Is there a built-in way to get "CREATE DATABASE app;" and app user created?

In a standard docker MySQL image there are options to get app user and database automatically when creating a MySQL instance for the first time.

For example:


Init script creates database for app without manual actions required.

If I’m right, when creating a new PXC cluster all yamls can be applied in one go, if app user/database-name/password would be in deploy/secrets.yaml and these details picked up to:


… and app should be able to start using a new DB without manual steps

(just interested to think on what is missing to get a cluster in one button click)

Obviously, this can be easily done in an additional container, if this automation is not offered for now.

Anyway, I have this in my CI/CD pipeline to solve it:

echo "Create app database"
rootpw=`kubectl get secret -n $namespace $secrets_resource_name -o json | jq -r '.data.root' | base64 --decode`
apppw=`kubectl get secret -n $namespace $secrets_resource_name -o json | jq -r '' | base64 --decode`

kubectl exec -it ${sts_pxc}-0 -n $namespace -- mysql -h${sts_haproxy} -uroot -p$rootpw -e "CREATE DATABASE IF NOT EXISTS app; CREATE USER IF NOT EXISTS \"app\"@\"%\" IDENTIFIED BY \"$apppw\"; GRANT ALL ON app.* TO \"app\"@\"%\"; FLUSH PRIVILEGES; SHOW DATABASES;"

So please feel free to close an issue.


Hello @Laimis ,

we have this feature in our roadmap. But it is not high priority because it can be easily solved with CICD or other automation tools.

Cool. No worries and thanks for input. I have already proved that this xtradb solution is capable to be deployed/provisioned in “one click”.

Hi @Laimis
If you need to init something bigger than empty the database - you can start a new cluster, manually put all required schemas and data and make a backup after all.
The next time when you need to create a new instance of the database with the same data - you can recover from backup immediately after empty cluster creation.

Thanks. This is another option.
