MySQL failed

MySQL failed on startup.

This is a very rare error. It has to do with sharing of layers (we think). So in fact, we haven't been quite able to figure it out, but we have a solution.

Solution for all Images since 2020-11-05

We have fixed that error on 5th november 2020. So just pull the newest image and the error should not happen again.

Please keep in mind that this will remove any persistent data if you do not have mounted a volume for mysql.

You have to remove the volumes for your container.

Attention

Please keep in mind that this will remove any persistent data that you have. Think about this step before proceeding.

We start by removing our container. Use this script with the name of your actual container (shopware in our case).

ON HOST

docker rm -f [containername]

Now we have to remove the volumes. Let's find their names.

ON HOST

docker volume ls

Figure out what volumes belong to your image (by using their names) and then delete the mysql (and maybe shop) volumes.

OM HOST

docker volume rm -f [name]

If you now restart your docker container, it should work again. It's also time to restore your clean MySQL dump, if you have a running project ;)
