The argocd-bootstrapper leverages the Argo CD's App of Apps pattern on K8S by using Helm.
The following is the directory structure for the bootstrap process:
.
├── apps # bootstrap manifest per cluster
├── README.md
├── templates/apps # child app templates (one file per app)
├── templates/bootstrap.yaml # bootstrap manifest template
└── cluster # live manifests for parent apps per cluster
└── helpers-crds # deployed crds & helper apps per clusterFirstly set environment variable for related cluster.
export CLUSTER_NAME=local
export SERVER_ADDR="https://kubernetes.default.svc"
export REPO_URL="https://github.com/omerurhan/argocd-bootstrap.git"
Create app of apps bootstrap file
cat templates/bootstrap.yaml | envsubst '$CLUSTER_NAME,$SERVER_ADDR, $REPO_URL' > apps/${CLUSTER_NAME}.bootstrap.yaml
Copy templates files to related cluster folder and subst environments.
cp -R templates/apps/* clusters/${CLUSTER_NAME}
envsubst '$CLUSTER_NAME,$SERVER_ADDR, $REPO_URL' < clusters/${CLUSTER_NAME}/values.yaml | sponge clusters/${CLUSTER_NAME}/values.yaml
To bootstrap, apply the bootstrap.yaml file:
kubectl apply -f apps/${CLUSTER_NAME}.bootstrap.yaml
