AlertBlackbird30 :

--remote-gateway [REMOTE_GATEWAY] Advanced: Specify gateway ip/address to be passed to interactive session (for use with k8s ingestion / ELB)I see this in clearml-session - what’s the intent here?

maybe I am entirely wrong .. I read clearml-session as running a remote 'headless container with jupyter'.. but not on k8s.. or rather... the pre-requisites say that 'ssh access', which you won't have in a k8s cluster (I would hope). I mean.. exposing the ssh port on a k8s cluster is jst a security nightmare.

I am guessing it could be but.. I don't feel that k8s is clearml-session's main focus/push

Hey Manoj, I am not sure how clearml-session would know how to setup kube-proxy, if that's your intent.

Personally, I would run the clearml-server and agents on the k8s cluster, and then expose the server endpoints via kube proxy or some other nicer ingress. Then you can run jupyter locally and you should be good. Jupyter session remotely running on k8s would be a logistical nightmare 🙂

Thanks AgitatedDove14 - i get overall what you are saying. Have to get glue setup, which I couldn’t understand fully, so that’s a different topic 🙂

AlertBlackbird30 - i don’t understand why it can’t be a focus though. Probably missing some context.

The way I read that is if you have exposed your clearml-server via k8s ingress then you can, from outside the k8s, say to clearml-session this is the k8s ingress/ip

There is kubectl exec 🙂

I suggest using the apply template setup (basically you provide a Job/Service template, and it uses that to setup k8s jobs based on the Tasks coming in from the specific queue)

Ok so that’s nothing more than what I would configured in the clearml config then

Ah ok. Kind of getting it, will have to try the glue mode

I believe that's correct, yes

How is clearml-session intended to be used?

  
  
Posted 2 years ago

I would like to create a notebook instance and start using it without having to do anything on a dev box

“notebook as a service” right

Hi TrickySheep9
Long story short, clearml-session fully supports k8s (using k8s glue)
The --remote-gateway along side ports mode will basically allow you to setup a k8s service so that every session will register with a specific port so k8s does ingest foe you and route the SSH connection to the pod itslef, everything else is tunneled over the original SSH connection.
Make sense ?

But ok the summary is I guess it doesn’t work in a k8s env
