You can see [what that looks like on Dockerhub](https://hub.docker.com/r/blairdrummond/datasette/tags?page=1&ordering=last_updated)

And how it lets Datasette run on a Raspberry Pi (top is my dockerhub, bottom is upstream)

But it's pretty close.**

Closes https://github.com/simonw/datasette/issues/1344 . Using a build-matrix for the platforms and [this test](https://github.com/simonw/datasette/issues/1344#issuecomment-849820019), we test all the platforms in parallel. I also threw in container scanning.

### Switch `pip install` to use either tags or commit shas

Notably! This also [changes the Dockerfile](https://github.com/blairdrummond/datasette/blob/7fe5315d68e04fce64b5bebf4e2d7feec44f8546/Dockerfile#L20) so that it accepts tags or commit-shas.

```

This lets you build the containers in CI every push for testing, which maybe resolves [this problem](https://github.com/simonw/datasette/issues/1272#issuecomment-808648974)?

# Workflow run example

You can see the results in my workflow [here](https://github.com/blairdrummond/datasette/pull/2/checks?check_run_id=2690570717). The commit history is different because I squashed this branch, also in the testing branch I had to change `github.com/simonw` to `github.com/blairdrummond` for the CI to pick up my git_sha.

## Why did the builds fail?

**NOTE:** The results of all the tests fail, but for different reasons! A few fail to install Rust, the amd64 passes the tests (phew!) but has critical CVEs which fail the container scan, the Arm/v6 and Arm/v7 seem to fail to install the test dependencies due to missing programs like `gcc`. (`gcc` is not sufficient though, as [this run](https://github.com/blairdrummond/datasette/pull/3/checks?check_run_id=2690672982) indicates) ",107914493,pull,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/1348/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",0,
