Environment as a Service

This repo contains a set of gitops configuration to setup a developer platform based on OpenShift.

This repo mainly focuses on the Environment as a Service use case.

This repo tries to showcase a realistic scenario featuring:

1. a multi cluster setup: we have three cluster at play, hub, non-prod prod. Other clusters can be easily added.
2. a multi tenant setup: we have two teams configured: team-a, team-b. More teams can be easily added.
3. a multi environment setup: each application can have multiple environments. In this example we have: dev, qa (running in the non-prod cluster) and prod (running in the prod cluster)

This is a gitops repo build from the red hat CoP starter template and populated ion large part with elements from the red hat CoP gitops catalog

This example was built starting from the AWS ROSA Open Environment Red Hat demo catalog item, you might have to adjust pieces of the configuration if you start from a different place. Adjustments should be minimal.

To get started run the following:

export gitops_repo=https://github.com/environment-aas/platform-iac.git #<your newly created repo>
export cluster_name=hub #<your hub cluster name, typically "hub">
export cluster_base_domain=$(oc get ingress.config.openshift.io cluster --template={{.spec.domain}} | sed -e "s/^apps.//")
export platform_base_domain=${cluster_base_domain#*.}
oc apply -f .bootstrap/subscription.yaml
oc apply -f .bootstrap/cluster-rolebinding.yaml
envsubst < .bootstrap/argocd.yaml | oc apply -f -
envsubst < .bootstrap/root-application.yaml | oc apply -f -

To get the prod and non-prod cluster created you'll have to prepare a secret in the way ACM expects it, then run:

oc new-project open-cluster-management
oc delete secret aws-credentials -n open-cluster-management
oc apply -f ./.rosa/aws-secret.yaml

To deploy RHDH run the following (you need to have prepared the secret)

oc new-project redhat-developer-hub
oc delete secret rhdh-pull-secret -n redhat-developer-hub
oc delete secret github-pat -n redhat-developer-hub
oc create -f ./clusters/hub/overlays/redhat-developer-hub/rhdh-pull-secret.yaml -n redhat-developer-hub
