Running the image

The container image must be able to run on a read-only file system.

Running shell locally:

docker run -it --platform linux/amd64 --tmpfs "/tmp" --read-only --rm ghcr.io/standout/integrationer-steps-ruby-runner:<version> sh

When mounted in the Kubernetes cluster the folder /tmp is mounted as a emptyDir. Kubernetes does not set the correct permissions for /tmp. This will affect for example the Ruby Temp-folder lookup.

To correct this we use a initContainer to set the correct permission. sticky-bit is set on the /tmp/app-tmp folder. And this folder is set as out temp-folder using environment variable TMPDIR in this container.

Build and push to GitHub packages

A new release will publish a new image on GitHub packages.

Creating manual release:

docker build -t ghcr.io/standout/integrationer-steps-ruby-runner:latest -t ghcr.io/standout/integrationer-steps-ruby-runner:<version> .

Using Mac M1:

docker buildx build --platform linux/amd64 -t ghcr.io/standout/integrationer-steps-ruby-runner:latest -t ghcr.io/standout/integrationer-steps-ruby-runner:<version> .

Pushing:

docker push ghcr.io/standout/integrationer-steps-ruby-runner:latest
docker push ghcr.io/standout/integrationer-steps-ruby-runner:<version>
