Running on Kubernetes about vespa HOT 7 CLOSED

You can also take a look in the multinode AWS ECS guide. There you will see the two types of containers (which should correspond to two types of Kubernetes pods). The docker image is given a command to either be a configserver or services. Please note that you will have to know the hostnames of your config servers upfront and pass these in the environment variable described.

The host column in the documentation you mentioned is more like a mental model for where you would expect to see the processes. You can run everything on one host but in a larger production environment it makes sense to split up accordingly to reason about resource usage and handle lifecycle events.

For your questions, I would say 1) yes, 2) yes and 3) there is nothing technical why you should not run them on the same hosts.

As for Kubernetes we have limited experience with it - feedback on this would be very interesting.

On start/stop: There are only two different start/stop commands as you can see. The services should be started on all nodes in your cluster and configuration server on a fewer set of nodes (e.g 3) but configuration server can also run on the same node(s) as the services.

start services will start the Config sentinel process which needs the configuration server address to know which services it should start on a given node which again is configured in the application package which describes which high level services should where http://docs.vespa.ai/documentation/cloudconfig/application-packages.html.

We try to demonstrate this in the quick start http://docs.vespa.ai/documentation/vespa-quick-start.html but maybe the AWS multi-node guide is more informative on this http://docs.vespa.ai/documentation/vespa-quick-start-multinode-aws.html

@F21 Any updates on this?

@jobergum I haven't had a chance to try this out yet, but I hope to give it a spin before the end of the month.

Hi @aressem the link you've given http://docs.vespa.ai/documentation/vespa-quick-start-multinode-aws-ecs.html returns 404
I'm in need of a solution to run multinode vespa on Kubernetes.

@humayun0156 This is a 5-year-old issue. Living documentation move around. You can search for Kubernetes in current vespa doc here:
https://docs.vespa.ai/search.html?q=kubernetes

Good starting point is https://docs.vespa.ai/en/vespa-quick-start-kubernetes.html
