Fedora 31 Workstation
I am running mysql in a container using podman. After some experimenting I got
it running with this command:
podman run --detach --userns=keep-id \
--security-opt label=disable \
--name=mysql \
--env="MYSQL_ROOT_PASSWORD=mysql" --publish 3306:3306 \
--volume=/home/simon/servers/mysql/var/lib/mysql:/var/lib/mysql
mysql:8.0 \
--character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci \
--lower_case_table_names=1
The bits that took time to research were:
--userns=keep-id - which maps my user to the same uid in the
container
--security-opt label=disable - which disables SELinux in the container (dev
machine so OK)
I could then connect to the database using the mysql client:
mysql -u root -p -h 127.0.0.1 -P 3306
Now, after a dnf upgrade this has stopped working and I get an error message:
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)
The container is running and appears to be healthy. I've tried recreating the container and reinitialising the database
(by deleting all the files).
[simon@hedgehog ~]$ podman ps

Podman was updated during the upgrade, as was the kernel and a bunch of other
stuff.

Does anyone have any idea how I can get this working again? Or any clues as to
how I should go about investigating further?
Thanks,
Simon
