Podman: Podman ignores labels that are key only

Description

Podman 1.5.0 seems to ignore labels that are key only

# Podman version 1.5.0 on Ubuntu (doesn't work)
$ sudo podman run -d -l mylabel --network host docker.io/nginx
$ sudo podman ps --filter=label=mylabel
CONTAINER ID  IMAGE  COMMAND  CREATED  STATUS  PORTS  NAMES

$ sudo podman inspect 33cced6c675b
            "Labels": {
                "maintainer": "NGINX Docker Maintainers <[email protected]>"
            },

Same thing with Docker:

# Docker version 19.03.1 on Ubuntu (works)
sudo docker run -d -l mylabel --network host docker.io/nginx
# sudo docker ps --filter=label=mylabel
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS               NAMES
b8cb18efa8c9        nginx               "nginx -g 'daemon of…"   About a minute ago   Up About a minute                       romantic_brattain

Seems like a regression, because it seems to work with an older version

# Podman version 1.4.4 on CentOS (works)
$ sudo podman run -d -l mylabel --network host docker.io/nginx
$ sudo podman ps --filter=label=mylabel
CONTAINER ID  IMAGE                           COMMAND               CREATED                 STATUS                     PORTS  NAMES
949601197b0b  docker.io/library/nginx:latest  nginx -g daemon o...  Less than a second ago  Up Less than a second ago         musing_blackwell

This issue is already fixed with upstream code.

$ sudo ./bin/podman inspect f122ad694c04 -f {{.Config.Labels}}

map[maintainer:NGINX Docker Maintainers <[email protected]> mylabel:]

Shall be available with next release.

Closing.

Should be fixed in podman 1.6

This seems to have regressed again, at least on 1.8.0, running a container with just a key for the label doesn't add that label.l

podman run -p 9000:9000 -l minio_fetcher --env MINIO_ACCESS_KEY=... --env MINIO_SECRET_KEY=... --env MINIO_DOMAIN=localhost --rm --detach minio/minio:edge server /home/shared

"Labels": {
                "maintainer": "MinIO Inc <[email protected]>"
            },
