Connect Git Repository to ArgoCD

Connect This Repo To ArgoCD

This guide connects https://github.com/nsudhanva/homelab to ArgoCD so ApplicationSets can sync from Git.

Step 1: Get the initial admin password

Fetch the bootstrap password from the argocd-initial-admin-secret Secret:

kubectl -n argocd get secret argocd-initial-admin-secret \
  -o jsonpath='{.data.password}' | base64 -d; echo

Step 2: Sign in to ArgoCD

Use the CLI or UI. If you are on the tailnet, the UI is at https://argocd.sudhanva.me.

CLI

argocd login argocd.sudhanva.me \
  --username admin \
  --password "<INITIAL_PASSWORD>" \
  --grpc-web

If the CLI cannot resolve argocd.sudhanva.me, verify split DNS is configured and the tailnet resolver is reachable:

dig +short argocd.sudhanva.me @100.100.100.100

Follow Tailscale if the query times out or returns no records.

Step 3: Add the repository

The repo is public, so HTTPS is enough.

CLI

argocd repo add https://github.com/nsudhanva/homelab.git

UI

Open ArgoCD, go to Settings, then Repositories, then Connect Repo. Use the HTTPS URL.

Step 4: Verify ArgoCD can see the repo

argocd repo list

You should see https://github.com/nsudhanva/homelab.git listed as a repository.
