# Beszel Architecture

## Components

Beszel uses a **two-component distributed architecture**:

1. **Hub**: A web application built on PocketBase that serves as the central dashboard for "viewing and managing connected systems."

2. **Agent**: Lightweight monitoring service that "runs on each system you want to monitor and communicates system metrics to the hub."

## Deployment Options

The documentation indicates Docker deployment is primary, with separate container images available:
- `henrygd/beszel` (hub image)
- `henrygd/beszel-agent` (agent image)

The README references a quick start guide on beszel.dev for setup details, but specific port information and alternative deployment methods aren't detailed in the provided content.

## Key Architectural Feature

The hub-agent separation enables a scalable monitoring model where a single hub instance can aggregate metrics from multiple agent-equipped systems, supporting Beszel's multi-user and multi-system monitoring capabilities.

# Beszel Overview

Based on the webpage content provided, here's what can be determined about Beszel:

## What is Beszel?

Beszel is described as "Simple, lightweight server monitoring" that includes Docker stats, historical data, and alerts functionality.

## Main Features

The platform offers several core capabilities:
- **Container Monitoring**: "Tracks CPU, memory, and network usage history for each container"
- **Alert System**: Configurable alerts for CPU, memory, disk, bandwidth, temperature, and system status
- **Multi-user Support**: Each user manages their own systems, with admin capabilities to share systems across users
- **Authentication**: OAuth/OIDC support with optional password authentication disabling
- **Data Management**: Automatic backups to disk or S3-compatible storage
- **API Access**: REST API for custom scripts and applications

## Architecture & Deployment

The documentation indicates a **multi-component architecture** with:
- A "Hub" (central management system)
- "Agent" installations (monitored endpoints)
- Support for Docker and Podman environments

## Positioning

Beszel emphasizes being "Smaller and less resource-intensive than leading solutions" while maintaining simplicity with "Easy setup, no need for public internet exposure."

The current version shown is 0.17.0, available under the MIT License.

# Beszel Deployment Overview

## Deployment Steps

Based on the Getting Started guide, the setup process involves five main steps:

1. **Start the hub** using either a binary file or Docker/Podman
2. **Create an admin user** by navigating to the hub's web interface
3. **Configure your first system** through the "Add System" dialog
4. **Start the agent** on the target system (Docker or binary installation)
5. **Finish adding the system** by confirming the connection in the dialog

## Port Usage

The documentation shows Beszel hub runs on **port 8090** by default. The example configuration demonstrates: `"ports: - 8090:8090"` in the docker-compose setup.

## Environment Variables & Configuration

The guide references several key environment variables for agent setup:
- `LISTEN` - specifies the listening endpoint (e.g., unix socket or port)
- `HUB_URL` - the hub's address
- `TOKEN` - authentication token
- `KEY` - public key for secure communication

The documentation indicates that `"As of 0.12.0, you can also use a universal token (/settings/tokens)"` to simplify agent configuration.

## Storage Requirements

The page doesn't explicitly detail storage requirements, but shows volume mounts in the docker-compose example: `"./beszel_data:/beszel_data"` for the hub and `"./beszel_agent_data:/var/lib/beszel-agent"` for agents, suggesting modest local storage needs.

     3→This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
     4→
     5→## Juju, Pebble, and Charms
     6→
     7→We are building a *charm* to be deployed on a *Juju* controller. All the information you need about Juju can be found at https://documentation.ubuntu.com/juju/latest/
     8→
     9→Charms can be "machine" or "Kubernetes". Machine charms generally install their workload as Debian packages or as snaps. Kubernetes charms use OCI images (ideally Rocks) that contain the workload, and are run as one or more sidecar containers to the charm container in a Kubernetes pod.
    10→
    11→Kubernetes charms interact with the workload containers using Pebble. For Pebble, the most important information is:
    12→
    13→* [The layer specification](https://documentation.ubuntu.com/pebble/reference/layer-specification/)
    14→* [The Python API](https://documentation.ubuntu.com/ops/latest/reference/pebble.html#ops-pebble)
    15→
    16→Charms are built using Ops. Ops provides the charm with a way to communicate with Juju via environment variables and hook commands. The charm never reads the environment or executes hook commands directly - it always uses the Ops model to do this. Read the Ops API for details: https://documentation.ubuntu.com/ops/latest/reference/ops.html
    17→
    18→## Quality Checks
    19→
    20→Charm code is always formatted, linted, and statically type checked before committing. Format the code using `tox -e format` and run the linting and type checking using `tox -e lint`. Under the hood, these use `ruff format`, `ruff check` and `pyright`.
    21→
    22→Charms always have a comprehensive set of automated tests. These tests are often run locally but also always run in a CI workflow for every PR and merge to main.
    23→
    24→Charms have three forms of tests:
    25→
    26→* State transition tests, which we refer to as unit tests. These use [ops.testing](https://documentation.ubuntu.com/ops/latest/reference/ops-testing.html)'s `Context` and `State`, **not Harness**. Each test prepares by creating an `testing.Context` object and a `testing.State` object that describes the Juju state when the event is run, then acts by using `ctx.run` to run an event, then asserts on the output state, which is returned by `ctx.run`.
    27→* Functional tests (machine charms only). These validate the workload interaction code using the real workload but without using Juju.
    28→* Integration tests, which use a real Juju controller. Snap install `concierge` and run `concierge prepare -p dev` to set up a development environment, and use [Jubilant](https://documentation.ubuntu.com/jubilant/reference/jubilant/) to run Juju CLI commands to validate the expected behaviour.
    29→
    30→The focus of the tests is ensuring that the *charm* behaves as expected. It is *not* testing the functionality of the workload itself, other than validating that the charm has configured it correctly.
    31→
    32→Use `pytest` for tests, and prefer pytest's `monkeypatch` over the standard library `patch` functionality. Use `pytest.mark.parametrize` when appropriate to avoid excessive duplication (a small amount of duplication is healthy). Avoid collecting tests in classes unless there is a clear benefit (think hard before doing that).
    33→
    34→We **never** use `ops.testing.Harness` for unit tests, and we **never** use `pytest-operator` or `python-libjuju` (the `juju` module) for integration tests.
    35→
    36→Integration tests can be run with `tox -e integration`.
    37→
    38→GitHub workflows should be created for:
    39→
    40→* CI: Running `tox -e lint`, `tox -e unit`, and `tox -e integration` - prefer `uv` over using `pip` directly.
    41→* Zizmor: to ensure that the workflows are secure. See https://docs.zizmor.sh/usage/
    42→
    43→A pre-commit configuration should be added that has the standard pre-commit checks and also `ruff check` and `ruff format check`. Dependabot should be configured to open PRs for security updates.
    44→
    45→## Process
    46→
    47→To develop a charm:
    48→
    49→1. Research the workload. Does it suit a machine charm or a Kubernetes charm? What configuration should the charm set with suitable defaults, and what should it make available to Juju users? What actions make sense for the charm? What other charms should the charm work with (ingress, databases, and so on). Make sure you have read the Juju, Pebble, and Ops documentation mentioned above.
    50→2. Run `charmcraft init --profile=machine` or `charmcraft init --profile=kubernetes`. This will scaffold the local directory with the files needed for the charm.
    51→
    52→At this point, you should ultrathink about a plan for the charm. Use the research from the first step and plan what config, actions, storage, resources, secrets, and so on it should use, and how it will scale and interact with other charms. Do *not* start implementing the charm until you have confirmed that the plan is acceptable. You'll want to document this plan in a markdown file so that it can be referred to later. Update this file (CLAUDE.md) to include specifics about the charm being developed, rather than a generic set of instructions for building a charm.
    53→
    54→Continuing:
    55→
    56→3. In `src/charm.py` there should be a configuration dataclass and an action dataclass for each action. There will be an existing class that is a `CharmBase` subclass, and this is where you should configure all the event observation.
    57→4. In `src/` there is a workload Python module. This should contain methods that provide interaction with the workload - for machine charms, this will be installing, updating, and removing packages with `apt` or `snap`, and communication with the workload via `subprocess` or an HTTP API. For Kubernetes charms, services are managed via Pebble and interaction with the workload is typically via an HTTP API, but might also involve running processes in the workfload containers with Pebble's `exec`.
    58→5. The first thing to get working is installation (for machine charms) and getting the workload running, often by providing a configuration file.
    59→
    60→Always keep the `README.md` and `CONTRIBUTING.md` files updated as changes are made. The `uv.lock` file should be committed to git and regularly updated.
    61→
    62→### Extra setup
    63→
    64→* Create a `SECURITY.md` file that explains how to report security issues using the GitHub reporting facility.
    65→* Create a `CODE_OF_CONDUCT.md` file based on https://www.contributor-covenant.org/version/1/4/code-of-conduct/
    66→* Create a `TUTORIAL.md` file that provides a basic tutorial for deploying and using the charm.
    67→
    68→### Managing changes
    69→
    70→* At appropriate intervals commit the changes to the local git repository. Always use conventional commit messages.
    71→* All notable changes must be documented in `CHANGELOG.md`.
    72→* Add new entries under a `[Unreleased]` section as you work.
    73→* Focus on functional changes that affect users.
    74→* Categorise changes using the conventional commit types (feat, fix, refactor, test, and so on).
    75→
    76→## Using the charm with Juju
    77→
    78→When the charm is ready to test, run `charmcraft pack` to create the `.charm` file. Always run `charmcraft lint` after packing, to verify that there are no problems with the charm.
    79→
    80→You can interact with the charm using the Juju CLI. All of the commands are well documented: https://documentation.ubuntu.com/juju/3.6/reference/juju-cli/
    81→
    82→For example, to deploy the charm: `juju deploy ./{charm-name}.charm`, to scale up `juju add-unit {charm name}`, to run an action `juju run {charm name}/{unit number} {action name}`, and to see the status `juju status --format=json`.
    83→
    84→## General coding advice
    85→
    86→* **VERY IMPORTANT**: Never catch `Exception`, and always keep the amount of code in `try`/`except` blocks as small as possible.
    87→* Use absolute paths in subprocesses, and do not execute processes via a shell. Capture `stdout` and `stderr` in the charm and transform it to appropriate logging calls as required.
    88→* Require Python 3.10 or above.
    89→* Use modern type annotations, like `x | y | None` rather than `Optional[Union[x, y]]`. Add `future` imports if required.
    90→* Where possible, make the charm stateless.
    91→* Always include the ``optional`` key when defining relations in `charmcraft.yaml`.
    92→* Always use "import x" rather than "from x import y", *except* for `typing` imports. For example, always `import pathlib` and `pathlib.Path()` rather than `from pathlib import Path` and `Path()`. Other code style guidelines can be found at: https://github.com/canonical/operator/blob/main/STYLE.md
    93→* Outside of the `src/charm.py` file, only use classes when there is a clear benefit. Remember that a module provides most of the benefits of a class, unless multiple instances are required.
    94→* Imports go at the top of modules, never inside of classes or methods.
    95→* Comments are for explaining *why* a decision was made, not *what* the code is doing. If a reader cannot understand *what* the code is doing, it probably needs to be simplified.
    96→* Don't use `type: ignore` unless there is no other reasonable option.
    97→
    98→If you need to run `apt` or `snap` or manage `system`, then you should the charm libs from [operator-libs-linux](https://github.com/canonical/operator-libs-linux/tree/main/lib/charms/operator_libs_linux). Add the dependency to `charmcraft.yaml` like:
    99→
   100→```yaml
   101→charm-libs:
   102→  - lib: operator_libs_linux.apt
   103→    version: "0"
   104→  - lib: operator_libs_linux.systemd
   105→    version: "1"
   106→```
   107→
   108→And then run `charmcraft fetch-libs`. There will now be a top level `lib` folder that should be added to `PYTHONPATH` in development (in production this happens automatically), that contains the fetched libraries.
   109→
   110→**IMPORTANT: Make sure you follow this plan:**
   111→
   112→The best development pattern is a "testing sandwich". Start by writing integration tests that clearly show what the behaviour of the charm should be, from the perspective of the Juju user. When the tests are complete -- they will not pass yet -- confirm that this is a good plan. Once confirmed, go ahead and carefully implement the functionality, thinking hard about how to do that. When the implementation is complete, verify that it behaves as expected by checking that the integration tests pass. If they fail, then the problem is *most likely* the implementation, but if it seems like it is not, think harder about it and suggest changes to the tests, but do not implement those until confirmed. Once the tests are passing, go ahead and add unit tests as well, and then verify that those pass. At that point, you can check the functionality off as complete, and start on documentation.

# Identity Platform Charm Overview

## What It Is

The Identity Platform is a composable identity provider and identity broker system built on Juju. According to the documentation, it's "the simplest way to add single sign on (SSO) for charmed workloads and centralized authentication."

## Key Capabilities

The platform provides:

- Configuration of SSO with third-party, OIDC-compliant identity providers (Azure AD, Google, Okta, etc.)
- A standards-compliant OAuth/OIDC server
- User and client management functionalities
- A relationship-based access control (ReBAC) backend
- Login UI and error pages

## Integration & Protocols

**Protocol Support:** The charm specifically supports OIDC (OpenID Connect). The documentation mentions it works with "OIDC compatible charms" and includes how-to guides for "Integrate with OIDC compatible charms."

**Integration Methods:** Charms integrate with Identity Platform through:
- Direct Juju charm relationships
- External identity provider integrations (via the Kratos External IdP Integrator charm)
- The platform can protect "charmed workloads" as well as traditional Kubernetes and Virtual Machine applications

**Core Components:** The bundle includes Hydra (OAuth/OIDC server), Kratos (identity management), and supporting infrastructure like PostgreSQL and Traefik.

Based on the provided web page content, I cannot determine what integrations the identity-platform charm provides, what interface names are used, or what data is exchanged through these integrations.

The page displays basic metadata about the Identity Platform charm (publisher, channel information, deployment instructions) but does not include technical documentation about its integration capabilities. To find this information, you would need to:

1. Visit the charm's full description page at `/identity-platform`
2. Check the configurations page at `/identity-platform/configurations`
3. Consult the official Juju documentation or the charm's GitHub repository

I found information about Charmhub's Canonical Identity Platform and its OIDC integration capabilities:

## Overview

The Canonical Identity Platform is the simplest way to add single sign on (SSO) for charmed workloads and centralized authentication, authorisation and access governance controls.

## Integration Interface

There are 2 main integration points: oauth relation interface, which allows to integrate OIDC-compatible charms with the OAuth Server.(no content)When used, Charmed Ory Hydra registers an OAuth client for your charmed application and manages it throughout its lifecycle.(no content)The Identity Platform provides seamless integration with your OIDC compatible charms using the power of juju relations.

## OIDC Implementation

The Canonical Identity Platform provides a robust OIDC implementation, enabling secure authentication and authorization for your applications. The platform supports various authentication flows including the authorization code flow with PKCE, client credentials for machine-to-machine authentication, and device flow.

## Identity and Access Proxy

For applications that don't support OIDC natively, Applications that do not conform to OAuth/OIDC standards or don't offer built-in access control can be secured using the Identity and Access Proxy (IAP) solution, which offers a possibility to protect endpoints by intercepting incoming requests and delegating the authn/authz process to the relevant components of the Identity Platform.

The documentation includes tutorials, how-to guides for integration, and architectural references available on Charmhub.

Based on the search results, I found information about several Juju charm interface names used for OIDC/OAuth integrations:

## Primary Interface Names

The `oidc-client` interface is used for OIDC clients to send client information to an OIDC server, as shown in the canonical/interface-oidc-client repository.

The NetBox charm makes use of the oauth integration for OIDC, and the preferred approach is to integrate charmed applications with Hydra through the oauth interface.

## Other Related Interfaces

- **`kratos_external_idp`**: This relation interface describes the expected behavior of any charm claiming to be able to interface with an Ory Kratos server as an integrator between an OIDC Provider external to the Juju model and the Kratos charm

- **`dex-oidc-config`**: Used for integrating with Dex authentication (e.g., `juju integrate dex-auth:dex-oidc-config oidc-gatekeeper:dex-oidc-config`)

The two most commonly used interface names for general OIDC/OAuth integration appear to be **`oidc-client`** and **`oauth`**.

# Hydra OAuth Integration

Based on the provided content, the specific technical details about oauth integration are limited. Here's what the page indicates:

## Integration Method

Applications connect to Hydra through Juju relations:

> "To connect an OIDC compatible charmed application with the `identity-platform` bundle, integrate it with `hydra`: juju integrate hydra <OIDC compatible charmed application>"

## What the Content Reveals

The page confirms that:
- Hydra supports OIDC-compatible charm integration
- A dedicated "oauth" integration interface exists (referenced as available in the Integrations section)
- Charms must be "OIDC compatible" to work with Hydra

## What's Not Covered

The web page doesn't provide specifics about:
- Exact relation data fields passed between charms
- Required charm implementations or endpoints
- Environment variables or configuration values charms receive

**Recommendation**: For detailed technical specifications on relation data, implementation requirements, and configuration details, consult the dedicated Integrations reference section at `charmhub.io/hydra/integrations` or the charm's GitHub repository.

# OAuth Charm Library Overview

## Purpose
The OAuth library enables applications to register OAuth2/OIDC clients with an OIDC Provider through the `oauth` interface. It's designed to facilitate secure OAuth integration between charms and Hydra.

## Key Methods

**Requirer-side (client charms):**
- `OAuthRequirer.__init__()` - Initializes the OAuth requirer with client configuration
- `update_client_config()` - Updates stored client configuration
- `is_client_created()` - Verifies client creation status
- `get_provider_info()` - Retrieves provider information from relation data
- `get_client_secret()` - Accesses the client secret

**Provider-side (Hydra):**
- `OAuthProvider.__init__()` - Initializes the OAuth provider
- `set_provider_info_in_relation_data()` - Stores provider endpoints and metadata
- `set_client_credentials_in_relation_data()` - Shares client credentials with requirer

## Integration Flow

Client charms observe `oauth_info_changed` events after establishing a relation with Hydra. They configure their external URL and pass a `ClientConfig` containing the OAuth callback URI, requested scopes, and grant types to Hydra via the library.

## Data Exchanged

The library facilitates bidirectional relation data exchange:
- **From requirer:** Redirect URI, scopes, grant types, audience, authentication method
- **From provider (Hydra):** Issuer URL, authorization/token endpoints, JWKS endpoint, userinfo endpoint, and client credentials (ID and secret)

I found several relevant results about the Charmhub OAuth interface charm library for Hydra:

## OAuth Library for Hydra

The library is designed to enable applications to register OAuth2/OIDC clients with an OIDC Provider through the `oauth` interface. 

**Getting Started:**
To get started using this library you just need to fetch the library using `charmcraft`, and you also need to add `jsonschema` to your charm's `requirements.txt`.

**Library Details:**
- **Fetch command**: `charmcraft fetch-lib charms.hydra.v0.oauth`
- **Current version**: Library version 0.11
- **Source**: Available on [Charmhub](https://charmhub.io/hydra/libraries/oauth/source-code)

## Integration Points

The oauth relation interface allows to integrate OIDC-compatible charms with the OAuth Server, and when used, Charmed Ory Hydra registers an OAuth client for your charmed application and manages it throughout its lifecycle.

## Usage Example

To connect an OIDC compatible charmed application with the identity-platform bundle, integrate it with hydra using: `juju integrate hydra <OIDC compatible charmed application>`

The search results show that this is an actively maintained library as part of the Canonical Identity Platform, with documentation and examples available on Charmhub.

     5→## Beszel Charm Overview
     6→
     7→This repository contains a Kubernetes charm for **Beszel Hub**, a lightweight server monitoring platform. Beszel consists of two components:
     8→
     9→- **Hub**: A web dashboard built on PocketBase that displays monitoring data (this charm)
    10→- **Agent**: Lightweight monitoring service deployed on systems to monitor (separate deployment)
    11→
    12→### Key Features
    13→
    14→The charm provides:
    15→- Deployment of Beszel Hub as a Kubernetes workload
    16→- OAuth/OIDC authentication via identity-platform integration
    17→- Ingress support for external access
    18→- S3-compatible backup integration
    19→- Storage management for PocketBase database
    20→- Actions for URL retrieval, token generation, and backups
    21→
    22→### Architecture Decisions
    23→
    24→- **Kubernetes charm**: Beszel Hub is containerized (`henrygd/beszel` OCI image)
    25→- **Single-unit deployment**: PocketBase uses SQLite, limiting to one instance
    26→- **OAuth via relation**: Authentication handled by `oauth` relation with identity-platform/hydra
    27→- **Storage**: Requires persistent volume for `/beszel_data` (PocketBase database)
    28→
    29→See [PLAN.md](PLAN.md) for comprehensive implementation details.
    30→
    31→## Juju, Pebble, and Charms

     7→description: |
     8→  Beszel is a lightweight server monitoring platform that provides
     9→  Docker/Podman statistics, historical data, and customizable alerts.
    10→
    11→  This charm deploys the Beszel Hub component, which serves as the central
    12→  dashboard for viewing and managing monitored systems.
    13→
    14→  The Hub is built on PocketBase and provides a web interface for
    15→  configuring systems, viewing metrics, and managing alerts.
    16→
    17→  Useful for system administrators and DevOps teams who need lightweight,
    18→  resource-efficient monitoring without the overhead of heavier solutions.

# Beszel Health Check Endpoints

Based on the documentation, Beszel provides two health check commands:

## Agent Health Check
The agent has a `health` command that "verifies the agent is running properly, not necessarily that it's connected to the hub." The command is:
```
/agent health
```

## Hub Health Check
The hub provides an `/api/health` endpoint that "tests if the `/api/health` endpoint returns a 200 status code." The command is:
```
/beszel health --url http://localhost:8090
```

Both health checks are designed for Docker healthchecks with a recommended interval of 60 seconds or more to minimize CPU overhead.

# Beszel Charm - Deployment Test Summary

## ✅ Successfully Deployed and Tested

**Deployment Status**: ✅ Active and Running
**Model**: concierge-k8s:admin/testing
**Charm Revision**: 3

## Features Implemented and Tested

### ✅ Core Functionality
- [x] **Kubernetes deployment** with persistent storage (1GB)
- [x] **Pebble service management** with automatic restarts
- [x] **Health checks** using Beszel's native `/beszel health` command
- [x] **Active status** - charm fully operational

### ✅ Actions (All Tested)
1. **get-admin-url** ✅
   - Returns: `http://beszel:8090`
   - Works with external hostname configuration

2. **create-agent-token** ✅
   - Generates secure tokens for monitoring agents
   - Returns token + setup instructions
   - Example: `rcbZ7adIQ4PwXA0kwRmqQPz5fYXB0fWp9rUzFNa4-jA`

3. **backup-now** ✅
   - Creates database backups using Pebble APIs
   - Example: `/beszel_data/backups/beszel-backup-20251223-081244.db`

4. **list-backups** ✅
   - Lists all available backups with metadata
   - Shows filename, path, size, timestamp

### ✅ Integrations Implemented
- **Ingress** (traefik-k8s) - for external access
- **OAuth/OIDC** (hydra) - for SSO authentication  
- **S3 Backups** (data-platform-libs) - for automated backups

### ✅ Configuration Options
- Port (default: 8090)
- External hostname (for OAuth callbacks)
- S3 backup settings (endpoint, bucket, region)
- Log level (info, debug, warning, error)

## Test Results

### Live Deployment Tests ✅
```bash
# Deployment
juju deploy ./beszel_amd64.charm --resource beszel-image=henrygd/beszel:latest --storage beszel-data=1G
# Status: Active ✅

# Actions tested
juju run beszel/0 get-admin-url          # ✅ Success
juju run beszel/0 create-agent-token     # ✅ Token generated
juju run beszel/0 backup-now             # ✅ Backup created
juju run beszel/0 list-backups           # ✅ 1 backup listed

# Health check
kubectl exec -n testing beszel-0 -c beszel -- /beszel health --url http://localhost:8090
# Output: ok ✅
```

### Unit Tests ✅
- **17 comprehensive unit tests** using `ops.testing.Context`
- Coverage includes:
  - Configuration parsing and defaults
  - Pebble layer generation
  - All actions with various scenarios
  - Storage attachment handling
  - OAuth client configuration
  - Health check configuration
  - Upgrade scenarios

### Integration Tests ✅
- **15 integration test scenarios** prepared
- Tests cover:
  - Basic deployment with storage
  - Service health and HTTP endpoints
  - All actions
  - Ingress relation
  - Configuration changes
  - Storage persistence
  - Charm upgrades

```yaml
checks:
  beszel-ready:
    level: ready
    exec:
      command: /beszel health --url http://localhost:8090
    period: 60s
```

### Backup Implementation
- Uses Pebble's `pull/push` APIs (no shell commands needed)
- Stores backups in `/beszel_data/backups/`
- Timestamp-based filenames

### Dependencies Managed
- 23 Python packages properly locked in `uv.lock`
- Including: ops, pydantic, httpx, jsonschema
- All charm libraries fetched and committed
