Wiki Farm in Kubernetes
There are easier ways to get started with federated wiki. Here we are using wiki to drive some learning about kubernetes.
We're using MacOS, Docker Desktop, and k3d
brew cask install docker
brew install k3d
mkdir -p ~/.wiki-k8s ~/workspace/fedwiki
k3d create \
--server-arg --tls-san="127.0.0.1" \
--publish 80:80 \
-v "$HOME/.wiki-k8s:/macos/.wiki-k8s" \
-v "$HOME/workspace/fedwiki:/macos/fedwiki" \
--name wiki
Deploy Wiki
kubectl apply -f wiki.yaml
Play with the wiki
