[prometheus-users] Re: passwords in config file

[Brian Candler]

If you're talking about basic_auth in scrape jobs 
,
 
then use password_file instead of password.

Otherwise, please clarify, or give an example of the embedded 
username+password config you're talking about.

I'm not really clear about exactly what you are trying to do & what is 
happening.


Could you please show what you are running, the query, what you are 
expecting & what you actually see?

[prometheus-users] Prometheus Users

[Yashaswini K]

Hi Team,


Need one help, i would need to write a query which will check pod status 
for all cluster operator pods for all operator namespaces and trigger an 
alert along with details all of them are down or whichever pod is down.

below query can be used for the same? will it print whichever pod is down 

absent(kube_pod_info{pod=~".*authentication-operator.*|.*etcd-operator.*|.*ingress-operator.*|.*kube-apiserver-operator.*|.*kube-controller-manager-operator.*|.*kube-scheduler-operator.*|.*kube-storage-version-migrator-operator.*|.*monitoring-operator.*|.*network-operator.*|.*openshift-apiserver-operator.*|.*openshift-controller-manager-operator.*|.*cloud-credential-operator.*|.*cluster-autoscaler-operator.*|.*openshift-config-operator.*|.*console-operator.*|.*machine-api-operator.*|.*machine-approver.*|.*machine-config-operator.*|.*node-tuning-operator.*|.*storage-operator.*|.*prometheus-operator.*"})

[prometheus-users] passwords in config file

[Natacha Souza]

Hey guys,

I'm looking for some best practices advice for securing my prometheus 
stack, because I don't wanna have username+password for my targets in my 
prometheus.yml file

I've looked for environment variables because this is one way that I know 
of, and that turned out to be a huge discussion and a dead end. 

So what is you recommendation? What should I study/do ?

Regards,
Nat
