Continuous Integration and Deployment

⚠ Work in progress ⚠

Workflow Concept

for PRs, we run tests (duh)
for pushes to master (i.e. merged PRs), or pushes of tags:
- also run tests
- build all docker images and push them to the GitHub package registry
when new Docker images are published, re-deploy
- we could either poll for them (watchtower can do that)
- or we somehow notify the deployment server that new images are published (e.g. making a simple to request to some HTTP API)

TODO

build & publish nginx image
build & publish frontend image
create a docker-compose config that uses images from GitHub registry
make sure pulling from GH reg. works (needs auth via token, see below); try to automate with a small script

Pulling Docker Images from GitHub Registry

To be able to pull Docker images from the GitHub registry, you need an access token.

create token, give it package:read permission
store somewhere (e.g. ~/.wartefrei.token)
cat ~/.wartefrei.token | docker login docker.pkg.github.com -u USERNAME --password-stdin
docker pull docker.pkg.github.com/methodpark/digitaleswarten/wartefrei-backend:latest
