Accessing the Web UI​

helm install argo-cd charts/argo-cd/

The Helm chart doesn’t install an Ingress by default, to access the Web UI we have to port-forward to the argocd-server service:

kubectl port-forward svc/argo-cd-argocd-server 8080:443

Get pass​

kubectl get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

Reset pass​

kubectl -n default patch secret argocd-secret \

-p '{"stringData": {"admin.password": "$2a$10$xxx","admin.passwordMtime": "'$(date +%FT%T%Z)'"}}'

argocd repo add [email protected]:xxx/abc-autotest.git --ssh-private-key-path ~/.ssh/id_rsa_argo
