Deploy Plunk with Levelrail

In the dashboard, open Apps, choose New app, then Browse templates, and select Plunk. Review the Compose body and deploy. With the CLI:

levelrail-cli templates get plunk --output json | jq -r .compose > plunk.compose.yaml
# edit plunk.compose.yaml to set the variables you must provide
levelrail-cli apps deploy-compose my-plunk --file plunk.compose.yaml
