{
    "target:develop": [
        "envs/development"
    ],
    "target:staging": [
        "envs/staging"
    ],
    "target:production": [
        "envs/production"
    ],
    "target:all" : [
        "envs/development",
        "envs/staging",
        "envs/production"
    ]
}

2. Create GitHub Labels

CUI

If the jq and gh commands are installed, the following commands are useful.

export REPO=ponkio-o/select-target-action
export COLOR=5319E7
cat .deploy_target.json | jq -r 'keys | .[]' | xargs -I @ gh label create @ --color $COLOR --repo $REPO

ref. https://cli.github.com/manual/gh_label_create

Example

$ cat .deploy_target.json | jq -r 'keys | .[]' | xargs -I @ gh label create @ --color $COLOR --repo $REPO
✓ Label "target:all" created in ponkio-o/select-target-action
✓ Label "target:develop" created in ponkio-o/select-target-action
✓ Label "target:production" created in ponkio-o/select-target-action
