Description

When using daemon-config on a Windows runner, the config file gets rendered without any double quotes and so is invalid JSON. The config then gets ignored when the daemon starts so it's quite tricky to tell what's going on.

Example:

with:
  daemon-config: |
    {
      "experimental": true
    }

Becomes { experimental: true } in daemon.json.

Expected behaviour

For daemon-config to render valid JSON.

Actual behaviour

Invalid JSON.
