Heroku: How to release an existing image in gitlab CI/CD?


I would like to deploy my application as a container from Gitlab CI/CD pipeline.

A few days ago I could deploy my docker image as written in the heroku devCenter.

docker login --username=_ --password=$(heroku auth:token) registry.heroku.com

and pushed it to the heroku registry.

docker tag imageregistry.heroku.com/app/process-type

docker push registry.heroku.com/app/process-type

But then they changed the deploy in 2 steps

heroku cointainer:push

heroku container:release

Before the update it was deployed when the container was pushed into the container registry. Now I need to release it in any way.

I tried to rename the image to release and tried to install heroku CLI but then I cannot log into heroku registry.

How did you solve it?


Solution

  • Here's a working solution I found yesterday which trigger a release. You can keep your deployment with docker and just add this little script to your pipeline.

    #!/bin/bash
    imageId=$(docker inspect registry.heroku.com/$YOUR_HEROKU_APP/web --format={{.Id}})
    payload='{"updates":[{"type":"web","docker_image":"'"$imageId"'"}]}'
    curl -n -X PATCH https://api.heroku.com/apps/${YOUR_HEROKU_APP}/formation \
    -d "$payload" \
    -H "Content-Type: application/json" \
    -H "Accept: application/vnd.heroku+json; version=3.docker-releases" \
    -H "Authorization: Bearer $YOUR_HEROKU_API_KEY"
