Kubedon

A Mastodon conf for Kubernetes / Google Container Engine.

Prerequisite: Generating Secrets

CloudSQL

Enable the Cloud SQL Administration API.

Create a Cloud SQL PostgreSQL instance.

Create the secrets for the proxy as described in Connecting from Google Container Engine. Note that we also add instance_connection_name to cloudsql-secrets. Furthermore take note of the PostgreSQL proxy user credentials, as they will be referred to as PROXY_USER and PROXY_PASSWORD later.

$ kubectl create secret generic cloudsql-secrets \
  --from-file=credentials.json=[PROXY_KEY_FILE_PATH] \
  --from-literal=instance_connection_name=[INSTANCE_CONNECTION_NAME]

Mastodon Conf Secrets

$ kubectl create secret generic mastodon-secrets \
  --from-literal=PAPERCLIP_SECRET=[FIRST_RANDOM_STRING] \
  --from-literal=SECRET_KEY_BASE=[SECOND_RANDOM_STRING] \
  --from-literal=OTP_SECRET=[THIRD_RANDOM_STRING] \
  --from-literal=LOCAL_DOMAIN=[YOUR_DOMAIN] \
  --from-literal=DB_USER=[PROXY_USER] \
  --from-literal=DB_PASS=[PROXY_PASSWORD]

Let's Encrypt Certs

Generate Let's Encrypt Certs.

$ kubectl create secret generic web-certificates \
  --from-file=fullchain.pem \
  --from-file=privkey.pem

Run Migration

TBD

Somehow run RAILS_ENV=production bundle exec rails db:migrate on a container that has been seeded with the same env variables as the web container.

Apply Conf

$ kubectl apply -f .
