Improvement for metroae container ssh copyid

[toweber]

Would it be possible to make this command usable without specifying a host so that the ssh key is copied to all required hosts present in the deployment files?
Right now if I want to start using the metroae container for an already existing deployment I have to run metroae container ssh copyid for all deployed components (except VSCs ofc).

This is a great suggestion. I will create a JIRA ticket to track this internally. Thank you.

METROAE-419 has been created.

Thanks a lot! Will this include all Nuage components (linux based, not VSC of course) as well as target servers? Or only a subset?

We will support Linux-based components and Linux-based target servers. We will use the credentials provided in credentials.yml or default credentials when credentials are not provided.

Okay. I was just looking at the dev branch and could only find this role: https://github.com/nuagenetworks/nuage-metroae/blob/dev/src/roles/make-copy-sshid-automatic/tasks/main.yml
And this one only includes VSD and VSTAT so I was wondering if the other components as well as their target servers are also considered.

@toweber you are correct. I was wrong. The implementation that we delivered to the dev branch only covers VSD and VSTAT. Your question suggests that we should add KVM-based target servers. Since we don't support upgrade of NUH and VNSUtils, it seems that there are no other VSP components to add support for. What am I missing?

[toweber]

One thing that I can think of would be if MetroAE only takes care of the "deploy" but not the "predeploy". For that scenario I guess it would also be valuable / convenient to be able to copy the ssh key to NUH (or vnsutils). Currently seeing this with my customer. They have a separate team that only takes care of VM provisioning in VMWare up until IP connectivity.
What do you think?

In v4.5 (about to be released) we have the following workflows:

• metroae vsd copy sshid that copies '~/.ssh/id_rsa.pub' to all VSDs in the deployment. This can be helpful in the scenarios when the VM bring-up is done outside of MetroAE or we are doing an upgrade on something that existed previously.
• metroae vstat copy sshid that does the above for the ES nodes defined in the deployment.
• metroae container ssh copyid that copies the MetroAE container's ssh key to the specified host

from this discussion, I think additional functionality should be considered:

• Add NUH to the list of supported nodes.
• Add target servers to the list of supported nodes.
• Add support for copying the container's ssh key to VSD, ES, NUH and target servers. (Not a separate workflow. Code should be smart enough to detect when the container is being used...)
• Add a workflow for copying to all nodes in a single operation.
• Add support for specifying the ssh key file to copy - might not be the default in the non-container case.

@toweber what do you think?

METROAE-445 has been created to track this issue.

That sounds great!
