In my QNAP NAS, I've installed a MySQL container, but after trying to start it, there is a console error:
You need to specify one of the following as an environment variable: MYSQL_ROOT_PASSWORD, MYSQL_ALLLOW_EMPTY_PASSWORD, _MYSQL_RANDOM_ROOT_PASSWORD.
I can't see any way to configure the container with such variables. I can see the configuration in Inspect, but this is not editable. Separate to Inspect, if I click Edit, I cannot add any such variable.
If I click Attach Terminal, there is an error "Container not running", and I can't start the container due to the error above.
Help appreciated.
As we got in comment, when creating MySQL container there should be Environment section in Advanced Settings, there you can specify for example MYSQL_ROOT_PASSWORD and value root
Before creating any container I encourage your to read documentation on https://hub.docker.com, in this case it will be https://hub.docker.com/_/mysql. There you can find many information that will help you to prepare it correctly
