Prerequisites for `dns-in-codespace`:
- Have `gh` installed, this provisioner is using the GitHub CLI to get the name of the current GitHub Codespace.

Initialize your local workspace, by importing a specific community provisioner:

score-commpose init --provisioners REPLACE-ME-WITH-ACTUAL-PROVISIONER-FILE-URL.yaml

Note: you need to replace REPLACE-ME-WITH-ACTUAL-PROVISIONER-FILE-URL.yaml by the actual provisioner file you want to use and import. More information here.

Get the provisioners definition:

score-compose provisioners list

Generate the platform specific manifests:

score-commpose generate score.yaml

See the resource outputs:

score-commpose resources list

You can run the following command on each resource listed with the previous command to get their outputs:

score-commpose resources get-outputs

Deploy the generated manifests:

docker compose up -d

See the running containers:

docker ps
