NSO in Docker containers and Kubernetes

[frjansso]

Lately we have received questions on running NSO in Docker and in some cases using Kubernetes.

I have started to collect examples and write down some thoughts. Everything can be found here, GitHub - NSO-developer/container-examples, any feedback is welcome.

So we have been experimenting with NSO in containers, and have come across an issue when implementing HA between NSO master and slave containers, when they are in different pods or VMs.  The internal IP is translated by the VM (source Ip changed) when communications takes place between the master and slave nso containers.

In the master HA config in CDB i specify the master (local ip of master contaiiner) and slave (external ip of slave container).  When the DB syncs to the slave container - the slave container's CDB now says the same.  But this wont work, since the slave container must communicate to the master using the master's external IP.......

MasterContainer(10.1.1.1) ---Ext(172.16.1.1)<------------------>Ext(172.16.1.2)-----SlaveContainer(10.1.1.2)

Options to address this ?  Moving the HA config out of CDB would help

Would using the "dns" names work?
