Docker DB container doesn't start

[tom-s07]

Following the installation docs from https://fusionauth.io/docs/v1/tech/installation-guide/docker doesn't result in a working fusionauth docker setup.

DB container fusionauth-db-1 doesn't start due to version conflict.

Ah, had apparently run fusionauth a while ago on this machine already and there was an old volume still laying around. Removing that solved the issue.
