Deploying to OpenShift

In order to deploy to a kubernetes cluster, follow these steps. Kustomizeopen in new window is used to deploy to Kubernetes. You will also need the OpenShift CLIopen in new window

  • Create a folder for your deployment for this example we use deployment
  • Add a kustomization.yaml and a patch.yaml to your deployment
  • Copy the sample code into these files and add configuration and secretes
  • Create images for your deployment, which needs to be accessible by your deployment, and also match the architecture of kubernetes cluster (amd/arm)
  • Deploy to OpenShift using the oc apply -k command

Deploying

# Create a kubomization.yaml, and patch.yaml
# View your deployments (outputs to screen, but doesn't apply to OpenShift)
oc kustomize ./deployment
# Deploys and applies to OpenShift
oc apply -k ./deployment
