How to rollback in liquibase when using docker for deployment

I started using liquibase for one of our spring-boot projects. Using Gitlab CI, we are creating the Image and deploying it. Everything is working fine. But I am stuck at rollback.

I have gone through the liquibase rollback documentshttps://www.liquibase.org/documentation/rollback.html

but I can perform rollback either using cmd or maven plugin. But the issue in my case is all thing packaged in an image and deployed. There is no system on which I can run these command. So how can I perform the rollback. Thanks in advance.
