Multiple Ostinato nodes in Containerlab

[Aninda Chatterjee]

Hi -

I am trying to instantiate multiple Ostinato nodes in Containerlab, example below:

    src1:

      kind: linux

      image: ostinato/ostinato:v1.3.0-1

      ports:

        - 5900:5900/tcp

    src2:

      kind: linux

      image: ostinato/ostinato:v1.3.0-1

      ports:

        - 5901:5901/tcp

However, it appears that only the port 5900 is made available. I cannot access the second node. Nor can I access the first node if I change its port number to anything other than 5900. 

Any help is much appreciated!

Regards,

Aninda

Hi Aninda,

Please change your config as shown below and try -

    src1:

      kind: linux

      image: ostinato/ostinato:v1.3.0-1

      ports:

        - 5900:5900/tcp

    src2:

      kind: linux

      image: ostinato/ostinato:v1.3.0-1

      ports:

        - 5901:5900/tcp

The only change is that for src2 host port 5901 is mapped to container port 5900. The container port to access VNC will always be 5900. You can change the host port, but not the container port.

This change should fix the access problem.

That said, why do you need multiple Ostinato nodes?

One Ostinato node with multiple links is the recommended and easier deployment so that you can access everything through a single GUI.

Let me know if this fixes the problem.

Hi Aninda,

Did the .yml file change I suggested in my previous email help with VNC access for the second node?

Hi Srivats, 

Yes, that worked. But like you said, it made more sense to just use one node with multiple interfaces connecting to different parts of the network.
