Runnable Docker image for the Hyperledger Aries Cloudagent

Docker images for Hyperledger Aries Cloud Agent

The image repository is located on Docker Hub.

The images include language-specific implementations of Aries Cloudagent such as:

• Aries CloudAgent Python (ACA-Py)

Repository structure

The repository is structured so that there is a folder for each implementation/language , and this contains the dockerfiles and resources required to build and test the output image.

Inside make_image.py a data structure called VERSIONS describes the versions and base image for each implementation/language.

Adding a new implementation/language

To add a new implementation/language:

1. create a new folder named after the new implementation in the root of the repository. For reference, the python folder can be copied and its contents updated to reflect the new implementation/language.
2. Update the VERSIONS object in make_image.py to add the new implementation/language details.

Image versioning

All the aries-cloudagent images will reside on the Aries Cloud Agent Docker Hub, and will differentiate between each other by using specific tags.

By default, the tag for a new image will be composed by $base_image_tag, followed by _$agent_version. Because of this naming convention, please make sure you use a tagged version for each base image rather than using latest or a more generic tag that is not as descriptive.

Building the image locally

This project is setup to use Visual Studio Code Remote - Containers. The devContainer includes everything you need to work on the project and build the images. The container uses docker-from-docker so any images you build will show up in your host's docker repository.

Pre-requisites

Using the devContainer:

• Visual Studio Code with the Remote - Containers extension installed.
• Docker

To develop and build the image locally you will need to install:

• Python 3
• Docker

Running the build

To build the image, open a terminal session at the root of this git repo and execute: python make_image.py 0.3.0 python, replacing 0.3.0 with the aries-cloudagent version you need.

Additional parameters can be specified through command-line, for more information please type python make_image.py --help to display the command's usage page.

Building an image from a GitHub source

In some cases you may want to build an image from a particular repository and branch. You can do this by adding the git_egg_ref build-arg to the command line. In this case the version number you specify will only be used to determine the relevant base_image and acapy_reqs to use for the build.

The format of the git_egg_ref argument is:

• git+<git_repo_url>[@<git_ref>]#egg=
  • Where:
    • <git_repo_url>: Is the url to the repo including the trailing .git extension.
    • <git_ref>: Optional. The git_ref of the branch or tag to use. If specified, the <git_repo_url> and <git_ref> must be separated by a @.

Example:

./make_image.py 0.7.3 python --build-arg git_egg_ref="git+https://github.com/WadeBarnes/aries-cloudagent-python.git@persistant_queue#egg="

Adding and Publishing a New Image

To add a new version of aries-cloudagent to this repo, create a PR with the following changes:

• Decide on the base image to be used for the image, and the version of Aries Cloud Agent.
  • The image tag of the output will be a concatenation of the two, as indicated in the table above.
• Update the table in this readme to add the new version.
• Edit the make_image.py file in this repo to add the new version.
• Create and test the build of the local image using the options --no-cache and --test
  • python make_image.py 0.7.2-rc0 --no-cache --test python
• If successful, push the image to the bcgovimages organization of Docker Hub using the --push option
  • python make_image.py 0.7.2-rc0 --push python
• If successful, verify the publishing of the image by checking Docker Hub
  • Note that it make take a few minutes for the new tag to appear. Hit refresh periodically until the image is visible.
