Opencontrail Initial Mods

[galthaus]

• opencontrail replaces kube-proxy (so turn it off)
• opencontrail needs a plug-in

This still needs some changes. The problem is that the opencontrail ansible playbook isn't necessarily completely modularized.

It is here: https://github.com/Juniper/container-networking-ansible

The way I currently use it is to:

1. clone setup-kubernetes
2. clone container-networking-ansible
3. copy the roles from container-networking-ansible into setup-kubernetes roles
4. copy the playbook file from container-networking-ansible/playbooks into setup-kubernetes
5. build an inventory file like normal but add masters (kube-master) nodes (kube-nodes) gateways and opencontrail which is all three groups.
6. Set up the opencontrail vars

This is rough and still needs help.

Great work, going to look at it

@Smana will integrate this commits as he refactored the network plugin

[galthaus]

I'm updating it with regard to the new plugin pieces. These are required, but outside of the network plugin path.

[galthaus]

Do not pull this yet. I'm still working on it to see if it can be made cleaner (not the code that is currently here, but the other parts needed for this).

[galthaus]

With this now in place, you can try to run open contrail like this:

1. clone setup-kubernetes
2. clone container-networking-ansible
3. copy the roles from container-networking-ansible into setup-kubernetes/roles/network_plugin
4. copy the roles from container-networking-ansible into setup-kubernetes/roles/network_plugin_provision
5. cope the files from container-networking-ansible into setup-kubernetes
6. build an inventory file like normal but add four groups:
   1. masters (kube-master)
   2. nodes (kube-nodes)
   3. gateways
   4. opencontrail which is all three groups.
7. Set up the open contrail vars in inventory/group_vars/all.yml

[galthaus]

Well - that isn't working well either. Still need custom cluster file. Networking needs to be setup before kubernetes node install and only on some nodes and not others.

Back to this:

opencontrail needs a plug-in
This still needs some changes. The problem is that the opencontrail ansible playbook isn't necessarily completely modularized.

6. Set up the opencontrail vars

[ant31]

do you want to keep container-networking-ansible separated ?

[galthaus]

@ant31: It is Juniper's playbook that is used for kubernetes and openshift. It works with both the kubernetes/contrib playbook and this one. I haven't worked to make it a standalone role(s) that could be pulled by galaxy. I may at some point.

suggestions:

1. clone container-networking-ansible
2. copy the roles from container-networking-ansible into setup-kubernetes/roles/network_plugin
3. copy the roles from container-networking-ansible into setup-kubernetes/roles/network_plugin_provision

This can be done automaticaly with local_action tasks, maybe in network_plugin/opencontrail/preinstall ?

1. cope the files from container-networking-ansible into setup-kubernetes

We can add a cluster-opencontrail.yml playbook in this repo.

1. build an inventory file like normal but add four groups:
   1. masters (kube-master)
   2. nodes (kube-nodes)
   3. gateways
   4. opencontrail which is all three groups.
      rename gateways -> opencontrail-gateways

We can also add inventory-opencontrail.cfg as an example inventory

1. Set up the opencontrail vars in inventory/group_vars/all.yml

I propose to use inventory/group_vars/opencontrail.yml and opencontrail-gateway.yml if needed and again add in this repo.

[galthaus]

Interesting. Might be do able. I've been also talking with Juniper about
making it ansible-galaxy ready as an alternative.

Hi Greg, did you have the time to work on this opencontrail support ?
Let me know if i can help you in anyways.

[Smana]

Hi @galthaus, what about this PR ?

[galthaus]

@zehicle is working on this now as well. I've been focused on some other things. I like the suggestions, but will require reworking our deployment methods and updating the PR.

[Smana]

Ok @galthaus thank you, i close this one then
