aries-acapy-plugins

This repository contains approved and tested plugins for Aries Cloudagent Python. This is to encourage collaboration and sharing of useful features not directly included in aca-py.

Developer Notes

• Open devcontainer in VS Code
• Python and all dependencies will be loaded
• Poetry will be loaded and configured, dependencies will be installed
• Docker and Docker Compose will be available

IMPORTANT: docker-in-docker can be a little flaky, so if you encounter a messages such as: "Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?" you should probably reboot VS Code.

Plugin Documentation

The development team should describe what the plugin does, any limitations (ex only in multitenant mode), any known issues interacting with other plugins, etc. Full documentation including a plugin_config sample should be provided.

This documentation should be provided in your plugin root as a README.md file. With at least a Description and Configuration section.

Build and Run

A Dockerfile is provided to run integration tests. This image is not intended for production as it copies the plugin source and loads its dependencies (including ACA-Py) along with a simplistic ACA-Py configuration file: default.yml.

Run and Debug

In the devcontainer, we can run an ACA-Py instance with our plugin source loaded and set breakpoints for debug (see launch.json).

To run your ACA-Py code in debug mode, go to the Run and Debug view, select "Run/Debug Plugin" and click Start Debugging (F5). Using default.yml, your agent swagger is available at http://localhost:3001/api/doc.

Testing

For the plugin to be accepted into this repo it must have adequate testing.

Unit Testing:

• There should be adequate unit testing coverage. A coverage report is created when poetry run pytest in ran from the devcontainer. A good mark to aim for is 90% but the quality of the tests on critical sections is more important than coverage percentage.
• Mocking can be challenging. Study the existing plugins in this repo and aca-py in general for good examples of mocks and fixtures.
• Put your unit tests in a tests folder in your plugin version path and name all files and test with the test_ prefix.

Integration Testing:

• All plugins should have a suite of integration tests. The base suite will be created for your plugin after running the updater script
• See integration tests. You should have everything you need to start integration testing and a sample test will be provided.

Deploy

For production use, plugins should be installed as libraries to an ACA-Py image.

This requires having a Dockerfile and a config file for your agent.

example Dockerfile:

FROM ghcr.io/hyperledger/aries-cloudagent-python:py3.9-0.10.3

USER root

# install plugins as binaries
RUN pip install git+https://github.com/hyperledger/aries-acapy-plugins@main#subdirectory=basicmessage_storage
RUN pip install git+https://github.com/hyperledger/aries-acapy-plugins@main#subdirectory=connection_update

USER $user
# copy configurations, choose at deploy time...
COPY ./configs configs

CMD ["aca-py"]

example config file (local single tenant):

auto-provision: true
label: plugins-agent

inbound-transport:
   - [http, 0.0.0.0, 9060]

outbound-transport: http

emit-new-didcomm-prefix: true
wallet-type: askar
wallet-storage-type: default

admin-insecure-mode: true

admin: [0.0.0.0, 9061]

endpoint: http://host.docker.internal:9060

genesis-url: https://indy.igrant.io/genesis

# Connections
debug-connections: true
auto-accept-invites: true
auto-accept-requests: true
auto-ping-connection: true
auto-respond-messages: true

log-level: info

# plugins
plugin:
  - basicmessage_storage.v1_0
  - connection_update.v1_0

Now you can deploy a agent with as many plugins as you want as long as they are decalred in your build config file and installed.

docker build -f <Dockerfile> --tag acapy_plugins .
docker run -it -p 9060:9060 -p 9061:9061 --rm acapy_plugins start --arg-file=<config-file> -->
