Digital Ocean K8s cheatsheet

Step 1 - Config `kubectl` client to work with a new cluster
1. Download cluster yaml config from K8s dashboard
2. `export KUBECONFIG=~/.kube/config:<new yaml file>`
3. `kubectl config view --flatten > config.new`
4  Remove ~/.kube/config. Rename config.new to config

kubectl config get-contexts
kubectl config use-context <new context>

Step 2 - Add K8s cluster to Gitlab
Instructions are self-explanatory. Leave "Let Gitlab Manage your cluster" unchecked 
https://gitlab.com/help/user/project/clusters/index.md#add-existing-kubernetes-cluster
- check Install Helm
- check Install Cert-manager

Step 3 - Enable deploy key
Gitlab docker build pushes image to internal image registry.  We need to provide a "deploy token" in K8s deployment in order to pull the image.
gitlap repo -> Settings -> Repository settings -> Deploy token
