kube-prometheus: need to add Toleration to Prometheus about kube-prometheus HOT 15 CLOSED

Very cool. 👍
Don't hesitate to ask in the Kubernetes Slack in #monitoring-mixins, if you have questions about writing the example.

We're always very happy to assist new-comers, please feel free to ask any question 🙂 .

The antiaffinity should be a good example on how to add these tolerations:
https://github.com/coreos/prometheus-operator/blob/master/contrib/kube-prometheus/jsonnet/kube-prometheus/kube-prometheus-anti-affinity.libsonnet

The PrometheusSpec allows to set the tolerations directly (same for AlertmanagerSpec):
https://github.com/coreos/prometheus-operator/blob/a7eb782ea174af819bd82c72be54946ed83bd7b3/pkg/client/monitoring/v1/types.go#L138

Instead of adding the tolerations to the config you have to merge them with the real Prometheus and Alertmanager objects.

Maybe we could also make this an example like antiAffinity, @brancz?!

@metalmatze I think that's a good idea. Either of you want to create a PR and add a mixin?

from kube-prometheus.

Thanks a lot @metalmatze ...that most definitely gave me a direction on how to proceed, even if I don't know golang, reading the code helped !

@brancz thanks i will try to put something together and submit a PR for it ...but please bare with me here it's gonna be my first one ever, I let you know as soon as I have something

from kube-prometheus.

wow ...there's a channel for that !? that's dope !! will do.
by the way i have something working as i wanted..now i'm just gonna craft that mixin thing and a followed up PR

Thanks guys

Hello Guys,

I am trying to increase the retention and use the pvc (persistent volume) for prometheus. And we do have example for it. When i copy and pasted that on the jsonnet/kube-prometheus folder and running the build.sh its giving the error:

+ rm -rf manifests
+ mkdir manifests
+ jsonnet -J vendor -m manifests example.jsonnet
+ xargs '-I{}' sh -c 'cat {} | gojsontoyaml > {}.yaml; rm -f {}' -- '{}'
RUNTIME ERROR: couldn't open import "kube-prometheus/kube-prometheus.libsonnet": no match locally or in the Jsonnet library paths
        example.jsonnet:2:4-54  thunk <kp> from <$>

        <std>:1176:5-33 function <anonymous>
        example.jsonnet:8:64-99 $


        During evaluation```

Any idea how to resolve that.

You need to have the jsonnetfile.json in your same directory and then run jb install (jb being the jsonnet-bundler) to fetch all necessary dependencies to build kube-prometheus.

@metalmatze : Thanks for the prompt reply.
To achieve that, i have copied the examples/prometheus-pvc.jsonnet to jsonnet/kube-prometheus and run the below commands:

1. jb install
2. ./build.sh

Now from where i can confirm that the retention and pvc has been added in the manifests so that i can apply on the cluster.

Apology, but new to jsonnet and kube-prometheus both.

from kube-prometheus.

No worries. Glad it works now!

@metalmatze: I have not applied in the cluster, just wanted to know where can i confirm the retention period and pvc configuration has been modified before i apply.

Also if we have any slack channel for this kind of issue, can you please provide the URL to join that.

from kube-prometheus.

Yes. We have. There's #prometheus-operator in the Kubernetes Slack. See you there! :)

from kube-prometheus.

Can you please provide the link, while searching the workspace kubernetes.slack.com, its asked to login and i am using my github registered email to do that or any other way to login to the kubernetes slack

from kube-prometheus.

Please ignore i was able to join the slack now
