Spinning up child pods in a different namespace

[Vignesh-Kathirkamar]

Hi, I have a nextflow pipeline which would carry out six process and all these six processes have to run in a different namespace.

For now, I am spinning up the main pod (kind: Job) in a namespace called "dev" and all the six process within the .nf file is spinning up the pods in "dev" namespace only. But now I want the main pod to run in the "dev" namespace and other pods in a different namespace, say "ft1".

I tried by changing the "k8s" spec within the config file as below:

k8s {
    namespace = 'ft1'
    serviceAccount = 'ft-ds'
}

but still got the error stating

User \"system:serviceaccount:dev-ds:dev\" cannot create resource \"pods\" in API group \"\" in the namespace \"ft1\"",

Is it possible to spin up the child pods alone in a different namespace?

Don't think the use of different namespaces is supported

As far as I have used nextflow, it's just spinning up the child pods in a specific order. So, why it's not possible to spin up those child pods in a different namespace.

[pditommaso]

because there's no way to specify the namespace at task level

I think he is only trying to run the head job in one namespace and all task pods in another. Should be possible as long as the head job namespace / service account has permission to submit pods to the other namespace

@bentsherman thanks for the reply. This helps.
