CouchbaseContainer is a final container and doesn't need SELF typing. Any good reason to add it back?

I don't see why testcontainers should forbid subclassing the couchbase container. This gives a user the possiblity to add something they need.
Aside from a slightly more complex definition on the class line, this adds a lot of flexibility for adding new with methods without disallowing chaining at the configuration level.
Example:
MyCouchbaseContainer c = new MyCouchbaseContainer()
.withClusterUsername("admin") // returns CouchbaseContainer
.withRoles("role1", "role2"...) // implemented in MyCouchbaseContainer and cannot be chained from CouchbaseContainer
.withClusterPassword("mops");There was a problem hiding this comment.
Another reason is consistency. A lot of containers ins the modules project provide exactly the same style.

the problem is that some languages (ahem Kotlin ahem) really suck at handling such types :D
This is why we decided to use self-typing only on base classes and not the final ones (new modules have that)
Also, Testcontainers 2.0 will have a new, generic-less DSL

So you suggest to revert that change?
And using return self(); is still okay?

Yes, please.
return self() is okay :)
These methods do not clone the instance and therefore do not default to the standard alpine:3.5 image - Added test to verify that the image name is not overridden by withXXX - Made CouchbaseContainer conforming to other modules' containers Replaced the extends mechanism by the project standard
