WordPress repo and prerequisites

info

This runbook covers the prerequisites and the initial GitLab project setup for a WordPress deployment that will be reconciled onto the cluster by FluxCD.

WordPress GitOps series​

  1. WordPress GitOps summary
  2. WordPress repo and prerequisites - you are here
  3. WordPress manifests
  4. WordPress flux integration
  5. WordPress operations, restore and backups

1. Prerequisites​

These prerequisites ensure the cluster and your workstation can support a GitOps-managed WordPress install.

1.1 Cloudflare prerequisites​

Complete your Cloudflare runbook first:

  • Ingress-NGINX is installed and healthy
  • cert-manager is installed and healthy
  • Cloudflare Origin CA Issuer controller (or equivalent) is installed
  • Cloudflare Tunnel (or other ingress path) is configured to your ingress
  • DNS for muppit.au is proxied via Cloudflare to your ingress

1.2 Flux prerequisites​

Ensure Flux is bootstrapped and you are using the correct root:

  • Root at ./clusters/my-cluster in flux-config

1.3 SOPS and age prerequisites​

Secrets must be encryptable locally and decryptable in-cluster:

  • Cluster Secret sops-age exists in flux-system
  • Your local age private key exists (so you can encrypt and decrypt on your workstation)

2. Verify local tooling (Mac)​

This confirms your workstation has the required CLIs and helps when debugging mysterious failures.

2.1 Check tool versions​

printf "
== Versions ==
"
for t in git kubectl kustomize flux sops age jq yq; do
  printf "%-10s %s
" "$t" "$($t --version 2>/dev/null | head -n1 || echo 'not found')"
done

2.2 Install pv​

pv helps with visible progress when streaming backups into pods.

brew install pv

3. Cloudflare portal: protect wp-login.php​

This protects against unauthorised access.

warning

Add a custom rule under Cloudflare Security rules → Custom rules to protect wp-login.php and /wp-admin.

4. Create the app repo (website/coach)​

This creates the WordPress application repository that Flux will pull and reconcile.

4.1 Create the GitLab project​

  • Group: website
  • Project: website/coach
  • Clone URL (HTTPS): https://gitlab.reids.net.au/website/coach.git

4.2 Give Flux read access (Deploy Key)​

Enable the same Flux deploy key you already use (flux-ssh-auth) as read-only:

  • GitLab project → Settings → Repository → Deploy Keys
  • Enable existing key flux-ssh-auth (read-only)

If you must recover the public key from the cluster (prefer your original copy instead):

kubectl -n flux-system get secret flux-ssh-auth   -o jsonpath='{.data.identity}' | base64 -d > /tmp/flux_id
ssh-keygen -y -f /tmp/flux_id > /tmp/flux_id.pub
# paste /tmp/flux_id.pub into Deploy Keys (Read-only)
rm -f /tmp/flux_id /tmp/flux_id.pub

4.3 Clone and create structure​

mkdir -p ~/Projects/website && cd "$_"
git clone ssh://git@git-ssh.reids.net.au/website/coach.git
cd coach
mkdir -p k8s/prod
git switch --create main
touch README.md
git add README.md
git commit -m "add README"
git push --set-upstream origin main

5. Next steps​

Proceed to the app manifests document to create the Kubernetes resources under k8s/prod/.

tip

If the namespace wp-coach does not exist yet, create it via flux-config before expecting the app Kustomization to reconcile cleanly.

6. Verification checklist​

  • flux --version and kubectl version --client return expected outputs
  • GitLab repo website/coach exists and has a main branch
  • Deploy key flux-ssh-auth is enabled read-only for the project
