Multiple Sources for an ArgoCD Application
ref: Argo CD has the ability to specify multiple sources for a single Application. Argo CD compiles all the sources and reconciles the combined resources. (argocd-multi-sources)[https://argo-cd.readthedocs.io/en/stable/user-guide/multiple_sources/]
Install ArgoCD
kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
kubectl patch deployments.apps -n argocd argocd-server \
--type=json \
-p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--insecure"}]'
Install argocd CLI
curl -sSL -o argocd-linux-amd64 https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64
sudo install -m 555 argocd-linux-amd64 /usr/local/bin/argocd
rm argocd-linux-amd64
ArgoCD CLI login
kubectl get secrets -n argocd argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d && echo
kubectl port-forward service/argocd-server -n argocd 8080:443 &
argocd login localhost:8080 --insecure
Add Git repo
USERNAME=npanda
TOKEN=hello
# Add Template Repo
REPO_URL=https://github.com/naren4b/demo-app.git
argocd repo add ${REPO_URL} --username ${USERNAME} --password ${TOKEN}
# ADD Value Repo
REPO_URL=https://github.com/naren4b/argocd-multi-source-demo.git
argocd repo add ${REPO_URL} --username ${USERNAME} --password ${TOKEN}
Deploy the App
git clone https://github.com/naren4b/argocd-multi-source-demo.git
kubectl apply -f dev-demo-argo-application.yaml -f staging-demo-argo-application.yaml
Check the manifest file & match with the values given
kubectl get cm -n demo-dev demo -o jsonpath="{.data.env}" && echo
kubectl get cm -n demo-staging demo -o jsonpath="{.data.env}" && echo
To check the templating is OK before applying
