A playground for codespaces with kind

Note: All commands are from the perspective of the root directory

Once your container comes up, there a couple of steps you need to execute.

• If you want to preload data into your database, add your sql statements to dat/data.sql
• From the terminal execute 'install_k8s'

• httpie: a command line tool for executing ReST API Requests
• k: k is aliased to kubectl so instead of typing kubectl get po you can type k get po
• psql: the postgresql client is installed

Note: These scripts are available on the PATH, you can execute them anywhere in the codespace environemnt from the terminal

• create_envlist: creates an env.list file in the current directory with the environment variables needed for connection for a running app (see notes about DB_HOST in Connection Data)
• db_connect: loads the environment and connects to the database in the terminal
• db_details: outputs the database connection details (see notes about DB_HOST in Connection Data)
• destroy_k8s: deletes the kind cluster and all resources for a fresh start, usually followed up with install_k8s
• install_k8s: creates a kind cluster and installs postgres, prometheus with grafana, and ingress-nginx
• populate_postgres: loads the file `/dat/data.sql' into the database

• It takes a bit on rebuild for docker to come back up, you can execute docker ps in the command line to see if it is up
• Since we are running Docker-in-Docker with kind, things can get out of whack there as well
  • If you find that there are no contexts in kubectl config get-contexts but kind get clusters responds execute a command kind export kubeconfig --name local and try again

• to add a script to the PATH, add it to the /scripts/ directory
