TF2 Wiki Kubernetes Config

This repository contains the non-sensitive Kubernetes declarations powering the Team Fortress 2 Wiki.

Secrets and credentials are managed separately in a Blackbox repository: tfwiki/secrets

Rough notes:

### Prerequisites

• Kubernetes cluster running 1.8.x (to avoid hardcoding NFS Service IP in PersistantVolume declaration)
• Cloud SQL database cloudsql-instance-credentials https://cloud.google.com/sql/docs/mysql/connect-kubernetes-engine
• Persistant disk for mediawiki images (mounted via NFS)
• Global Static IP address

Task list

1. Create cluster in Google Container Engine
2. Work on correct zone (gcloud config set compute/zone [COMPUTE-ZONE])
3. Log into new cluster (gcloud container clusters get-credentials [CLUSTER-NAME])
4. Set up config.yaml
5. Set up secret.yaml (see tfwiki/secrets)
6. Update ingress.yaml's metadata.annotations.kubernetes.io/ingress.global-static-ip-name and spec.tls.hosts (TODO: Generalise?)
7. Update nfs.yaml's spec.template.spec.volumes.gcePersistentDisk (TODO: Generalise?)
8. Update Google Cloud proxy command in mediawiki.yaml (TODO: Generalise?)
9. Spin up! kubectl apply -f k8s/common;kubectl apply -f k8s/ENVIRONMENT

Syncing files from the Valve-hosted wiki is managed via the media-sync job, but needs authorised SSH keys stored within a Kubernetes secret:

kubectl create secret generic media-sync-secret --from-file=ssh-privatekey=/path/to/.ssh/id_rsa --from-file=ssh-publickey=/path/to/.ssh/id_rsa.pub
