I'm running podman version 1.8.0 on Fedora 31 If I run with this command podman run --userns=keep-id \ --name=mysql \ --env="MYSQL_ROOT_PASSWORD=mysql" --publish 3306:3306 \ --volume=/home/simon/servers/mysql/var/lib/mysql:/var/lib/mysql:Z mysql:8.0 I can connect with the mysql client with no errors. mysql -u root -p -h 127.0.0.1 -P 3306 Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. etc. If I then do: podman stop mysql podman start mysql then I can no longer connect with the mysql client. mysql -u root -p -h 127.0.0.1 -P 3306 Enter password: ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111) I then reset everything: podman stop mysql podman rm mysql and delete all the database files. If I remove the --userns=keep-id argument I can connect after a 'stop' and a 'start'. (Except that the database files now have an odd user id that I can only delete as root) So, --userns=keep-id is the only difference and causing some sort of problem after a restart. I had this working using podman version 1.7 and I think that (and maybe the kernel) are the only things that have changed. Am I doing something wrong? Have I found a bug and would you like me to submit it? Simon
