- Ensure your version of `systemd` supports cgroupv2. [It must be at least `systemd` 247](https://github.com/systemd/systemd/issues/19760#issuecomment-851565075). Consider upgrading any `centos:7` images to `centos:8`.
- Containers running `systemd` need the following options: [`--privileged --cgroupns=host -v /sys/fs/cgroup:/sys/fs/cgroup:rw`](https://serverfault.com/questions/1053187/systemd-fails-to-run-in-a-docker-container-when-using-cgroupv2-cgroupns-priva).
### Known issue
Docker Dashboard incorrectly displays the container memory usage as zero.
You can use the [`docker stats`](../../../engine/reference/commandline/stats.md)
command on the command line as a workaround to view the
actual memory usage. See
[docker/for-mac#6076](https://github.com/docker/for-mac/issues/6076).
### Deprecation
- The following internal DNS names are deprecated and will be removed from a future release: `docker-for-desktop`, `docker-desktop`, `docker.for.mac.host.internal`, `docker.for.mac.localhost`, `docker.for.mac.gateway.internal`. You must now use `host.docker.internal`, `vm.docker.internal`, and `gateway.docker.internal`.
