Reading env vars fails to validate on pre-commit only

[cgarciaarano]

config.js

    // Host Rules
    secrets: {
        "MY_SECRET": process.env.SECRET,
    },
    hostRules: [
        {
            "hostType": "git-tags",
            "matchHost": "private.git.net",
            "password": "{{ secrets.MY_SECRET }}",
        }
    ],

Returns

 WARN: Found errors in configuration
       "file": "config.js",
       "warnings": [
         {
           "topic": "Configuration Error",
           "message": "Invalid `secrets.MY_SECRET` configuration: value must be a string."
         }
       ]

Oddly enough, running this from docker run -v $(pwd)/config.js:/usr/src/app/config.js renovate/renovate:41.90-full renovate-config-validator validates fine

It's because we cannot pass env variables to pre-commit.

The docker call includes the required variables.

We fixed it by adding

    hooks:
      - id: renovate-config-validator
        args: [--strict]
        files: ^.*/config\.js$
        entry: env MY_SECRET=foo renovate-config-validator
