This repository provides container images for linux/amd64 and linux/arm64.

This repository automatically checks the upstream Bitbucket repository for changes in the master branch. If there are changes, it will build a new container image and push it to the GitHub Container Registry and Docker Hub. The upstream private Bitbucket repository is https://bitbucket.org/terndatateam/docker-airflow/src/master/.

This image support for linux/amd64 and linux/arm64 with the following tags:

• latest
• major.minor.patch - e.g. 2.1.4
• major.minor.patch-build.<git-short-hash> - e.g. 2.1.4-build.c584b88

This image by default only supports linux/amd64. However, this repository provides linux/arm64 support with the following tags:

• latest-arm64
• major.minor.patch-arm64.<git-short-hash> - e.g. 2.1.4-arm64.c584b88

Test the GitHub Actions workflows using act.

Prior to running any workflows with act, you will need to create a .env file in the root of the repository. See .env-template for what environment variables are required.

Note: this will change the state of the main branch by updating CURRENT_COMMIT_HASH file if the latest upstream commit hash is different.

act --secret-file .env --env GITHUB_REPOSITORY=ternaustralia/airflow-container-image

Note: running the build workflow with act will fail on the last step where it builds and pushes to the GitHub Container Registry. The reason it fails is because we do not provide it with the values for github.actor to correctly authenticate with the registry. This is not a problem as we are only interested in seeing that building the container image succeeds.

This repository stores the current build version in the CURRENT_COMMIT_HASH file and performs a scheduled check roughly every 30 minutes via GitHub Actions to see if the upstream repository has any new commits. If there are new commits, it will build a new container image targetting linux/amd64 and linux/arm64 platforms and push it to the GitHub Container Registry and Docker Hub.

See .github/workflows/build.yml for the workflow that performs the build.
