api_modify container - not possible to modify existing container

[maksimsamt]

Related with v3170-a1 release.

Is it possible to add the new container, for isntance like this:

    - name: Container add
      community.routeros.api_modify:
        path: container
        data:
          - name: nginx
            remote-image: nginx
            interface: veth1
            ...
            entrypoint: "sleep"
            cmd: "infinity"
            hostname: my.hostname

But, afterwards it is not possible to modify this created container (in case if I change some parameter and re-run the playbook), there is such routeros built-in error:

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Error while creating entry: failure: Name already exists"}

I assume in this case we should use container update ... instead of container add ...

Versions:

Ansible v2.20.2
librouteros 3.4.2
ansible.netcommon 8.2.1
community.routeros 3.17.0-a2

Env:

Mikrotik RouterOS 7.21

With api_find_and_modify is it possible to modify existing container.
In the current situation with api_modify only possible to create/add new container.
Is that how it was intended?
It would be great to be able to add and modify within api_modify module.

I guess primary_key=("name",) is missing here.

Though I'm wondering why name should only be there from 7.19 on, it seems like a very basic container parameter to me. Not having that before 7.19 seems to make the path pretty much unusable IMO.

Container name is optional (in command container add).
If not defined then it created automatically (part from remote-image).
As far as I understand and remember, before version 7.19 there was no such restriction/validation on creating containers with the same name, thus, running the command (container add) with identical parameters created a new separate container.
