HuakunShen / pocketbase-docker

An always up-to-date docker image

Pocketbase Docker

Pocketbase doesn't provide docker image, but the image is very easy to build, simply download the executable to docker image and run it within docker.

Pocketbase releases for 3 linux arch, amd64, arm64 and arm/v7, thus I also build docker image for these 3 platforms.

The Dockerfile determines the latest url from platform and the latest release url.

GitHub CI

I am using a cron job with GitHub Action to run a check daily to check for new release. If there is a new release, the CI will build again with the new release tag automatically, so it's always up to date and I don't need to maintain this project.

./.github/workflows/cron-update-docker.yml caches a file containing the previous tag version, and compare with the current tag.

If the tag is unchanged, then all steps will be skipped. actions/cache@v3 is used for caching, although it's usually used for caching large dependencies like Rust's target and node_modules.
