1. Build test homeserver Docker images which can federate with each other
2. Run end-to-end (e2e) tests
#### Dev notes
Sharing variables across jobs when the `services` field can't access the `env` context, https://github.community/t/how-to-use-env-with-container-image/17252/24
```yaml
env:
FOO: bar
jobs:
set_env:
outputs:
var: ${{ steps.save_var.outputs.var }}
steps:
- id: save_var
run: echo "::set-output name=var::${{ env.FOO }}"
actual_job:
needs: set_env
container:
image: ...whatever_you_need_here...${{ needs.set_env.outputs.var }}
```
