Jx: node-js worker goes offline due to low ephemeral-storage

Summary

nodejs worker node goes offline during build.

kubectl events:

nodejs-qc2lb.15877af0bf79909c
The node was low on resource: ephemeral-storage. Container nodejs was using 40Ki, which exceeds its request of 0. Container jnlp was using 60Ki, which exceeds its request of 0.

Jenkins log:

Step 5/6 : COPY . .
Cannot contact nodejs-7pmmr: hudson.remoting.ChannelClosedException: Channel "unknown": Remote call on JNLP4-connect connection from ip-XXX-XXX-X-X.eu-central-1.compute.internal/XXX.XXX.X.X:41874 failed. The channel is closing down or has closed down

Steps to reproduce the behavior

sporadically happens when building npm apps.

Expected behavior

I tried to set a ephemeral-storage request in the nodejs template, but it looks like jenkinsci/kubernetes-plugin does not allow to set this.

Actual behavior

Jx version
