`podman-compose` currently does not support interpolating environment variables in dictionary keys, despite the compose file specification indicating this capability. See the relevant compose-spec documentation: https://github.com/compose-spec/compose-spec/blob/main/12-interpolation.md This feature is useful in `labels` or `environment` sections, where keys can be user-defined strings. To enable interpolation, an alternate equal sign syntax must be used, e.g.: services: foo: labels: - "$VAR_NAME=label_value" After this PR `podman-compose` will align more closely with the compose file specification, allowing for the interpolation of environment variables in dictionary keys.
