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?
