Allow to set Tolerations on pods (master & agents)

[pbecotte]

Need to set tolerations on the jenkins master/agent pods- doesn't seem to be a way to do so?

[pawelprazak]

Yes, thank you, this is another thing we need to address with #196

Also the master pod needs to have this configurable.

As for the dynamically created pods it should be possible from the pipeline.

[pbecotte]

Good point, the agent config is in the configuration as code plugin, just hadn't gotten there yet since the master can't deploy :)

[pbecotte]

As a question- I still can't figure out any way to work around this. Before I decide to uninstall this operator and get this working with the helm chart, is there a workaround that I'm not seeing?

[tomaszsek]

Tolerations for Jenkins master pod can be set in https://github.com/jenkinsci/kubernetes-operator/releases/tag/v0.3.1. We have to wait for #196 to set tolerations for seed job agent and I there is no workaround for this 😢

[pbecotte]

That is an impressive turnaround time!

[tomaszsek]

In https://github.com/jenkinsci/kubernetes-operator/releases/tag/v0.3.3 the tolerations for seed job agent are copied from spec.master.tolerations.

How can this be set ? I have tried adding under master in values.yaml
master: \ tolerations: [node.kubernetes.io/disk-pressure:NoSchedule]

[pbecotte]

That's not the format for tolerations:

                    tolerations:
                      - effect: NoSchedule
                        key: program
                        operator: Equal
                        value: $(PROGRAM)

That's not the format for tolerations:

                    tolerations:
                      - effect: NoSchedule
                        key: program
                        operator: Equal
                        value: $(PROGRAM)

So what would the equivalent be for the above disk-pressure ?

[deeco]

believe found it here, https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/

`tolerations:

• key: "node.kubernetes.io/unreachable"
  operator: "Exists"
  effect: "NoExecute"
  tolerationSeconds: 6000`

[deeco]

works , thanks @pbecotte

Does an agent have the same toleration parameter as a master, or tolerations work for master only?

[pbecotte]

agent configuration goes in the configuration-as-code configmap.

clouds:
  - kubernetes:
      name: kubernetes
      templates:
        - name: default
           tolerations: ...
