Openshift: Run docker-compoe in Openshift

Page content

Kompose is a open source tool that uses “docker-compose” file to deploy on kubernetes. Openshift is also Kubernetes based and Kompose is support Openshift too.

Parst of the Openshift series

Let’s say we have project with multiple microsevices that needs to deploy on Openshift and they have docker-compose.yml and Dockerfile. How do we deploy on Openshift?

Use Kompose to convert the docker-compose file to openshift compatible kubernetes config.

kompose convert -f docker-compose.yaml --provider=openshift

This command creates a separet yaml file for all kubernetes building block like “-imagestream.yaml”, “-service.yaml”, “-deploymentconfig.yaml” for each microservice. We can use these config files to deploy on Openshift easily.

kompose up --provider=openshift -f docker-compose.yml --build build-config --namespace=devopstales

If you have “build” option in docker-compose file, kompose automatically detects remote git url to deploy automatically.
