Known issue running mySQL 5.7* in Docker container

1

Many people run on mySQL 5.7+ and I wanted to share our findings before people lose their minds like we did.

https://github.com/docker-library/mysql/issues/69 - do NOT bother running MySQL 5.7 in a docker container. But we were trying with the Rancher EBS plug-in. Thinking we’d configured it wrong we researched, did tests and found that it’s not a Rancher, Rancher EBS issue. It’s just that mySQL 5.7 doesn’t run in a container.

Use MariaDB or a diff release of mySQL. Have a good day.

Many thanks I spent all day thinking this was something I was doing wrong, I removed 5.7 and installed 5.6 and it was all ok. It appears that 5.7 has some authentication issues. Best avoided.
