Start container - privileged mode:
docker run -it --privileged -e "container=docker" -v /sys/fs/cgroup:/sys/fs/cgroup:ro blgo/centos-systemd:base
Start container -without privileged mode (experimental):
docker run -it --tmpfs /tmp --tmpfs /run -e "container=docker" -v /sys/fs/cgroup:/sys/fs/cgroup:ro blgo/centos-systemd:base
Interact with the container:
docker exec -it container_name
Containers based on this image run using the following command on the base Dockerfile
CMD ["/usr/sbin/init"]
If this is overwritten, systemd won't work
docker run -it --privileged --restart always -e "container=docker" -p 3306:3306 -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mysql:/var/lib/mysql blgo/centos-systemd:mysql8
Then, get your temp password, which you will need for reseting the root password and adding new users.
grep -oP 'temporary password(.*): \K(\S+)' /var/log/mysqld.log
