This project is designed to bootstrap an OpenShift cluster using ArgoCD.
This repo is subject to frequent breaking changes while we all learn patterns to use as a team.

Bootstrapping a Cluster
- Verify you are logged into your cluster using
oc. - Clone this repository to your local environment.

Cluster Bootstrap
Execute the following script:
./scripts/bootstrap.shThe bootstrap.sh script will:
- Install the OpenShift GitOps Operator
- Create an ArgoCD instance in the
openshift-gitopsnamespace - Bootstrap a set of ArgoCD applications to configure the cluster
Sealed Secrets Bootstrap
bootstrap.sh will attempt to deploy sealed-secrets and requires a sealed secret master key to manage existing deployments.
If managing an already bootstrapped cluster, the sealed-secrets key must be obtained from the initial bootstrap (ask the person who initially setup the cluster).
The sealed secret(s) for bootstrap should be located at:
bootstrap/base/sealed-secrets-secret.yamlIf this is the first time bootstrapping a cluster, bootstrap.sh will deploy a new sealed-secrets controller and obtain a new secret if it does not exist.
