QUESTION
I'm following a tutorial https://docs.openfaas.com/tutorials/first-python-function/,
currently, I have the right image
...ANSWER
Answered 2022-Mar-16 at 08:10If your image has a latest
tag, the Pod's ImagePullPolicy
will be automatically set to Always
. Each time the pod is created, Kubernetes tries to pull the newest image.
Try not tagging the image as latest
or manually setting the Pod's ImagePullPolicy
to Never
.
If you're using static manifest to create a Pod, the setting will be like the following:

Answered 2021-Dec-28 at 08:33There are many agents capable of saving metrics collected in k8s to remote Prometheus server outside the cluster, example Prometheus itself now support agent mode, exporter from Opentelemetry, or using managed Prometheus etc.
QUESTION
I'm deploying a spring-boot application and prometheus container through docker, and have exposed the spring-boot /actuator/prometheus
endpoint successfully. However, when I enable prometheus debug logs, I can see it fails to scrape the metrics:
ANSWER
Answered 2022-Feb-07 at 22:37Ok, I think I found my problem. I made two changes:
First, I moved the contents of the web.config.file into the prometheus.yml file under the 'spring-actuator'. Then I changed the target to use the hostname for my backend container, rather than 127.0.0.1.
The end result was a single prometheus.yml file:
QUESTION
I’ve the following yaml which I need to apply using the K8S go sdk (and not k8s cli) I didn’t find a way with the go sdk as it is custom resource, any idea how I can apply it via code to k8s?
This is the file
Any example will be very helpful!

I'm trying to compare the behavior of go mod tidy
(and the resulting content of go.sum) to the output of go list -m all
.
Reading the docs, I understand go.sum contains the whole list of dependent modules declared in go.mod and in dependencies' go.mod files, go list -m all
shows the modules really loaded during the execution.
As an example, an application including logrus and prometheus like this:
go.mod
...ANSWER
Answered 2022-Jan-12 at 17:09Yes, it correct to say the modules really "used" by the application are listed by go list -m all
(as per documentation you provided the link of). By "used", it means the package selected at build time for the compilation of the go code of your application.
We had a similar issue with a static analysis tool and we had to change the configuration to use the output of go list -m all
(dumped in a file) instead of go.sum
.
QUESTION
The Google Managed Prometheus says that they cost $0.2 per million samples. However, in pricing examples they say:
Scenario 1: You have 100 containers, each writing 1,000 scalar times series.
Variant A: If each time series is written every 15 seconds (1 sample/15s), then the number of samples written per month is 17,420,000,000 (175,200 samples/month * 1,000 time series * 100 containers), or 17.42 million.
But 17,420,000,000 is 17.42 billion. So in that example, the price should be $3600, not $3.60, which is a pretty big difference to a pocket.
...ANSWER
Answered 2021-Dec-14 at 13:24You are right, this particular scenario is incorrect.
However, values in the table are correct - 18 million metrics would cost approximately $3.60.
Errors in documentation can be reported using the Public Issue Tracker.
You can also use the Google Cloud Pricing Calculator to estimate cost of your metrics.

I am working with a simple ML model with streamlit. It runs fine on my local machine inside conda environment, but it shows Error installing requirements when I try to deploy it on share.streamlit.io.
The error message is the following:
ANSWER
Answered 2021-Dec-25 at 14:42Streamlit share runs the app in a linux environment meaning there is no pywin32 because this is for windows.
Delete the pywin32 from the requirements file and also the pywinpty==1.1.6 for the same reason.
After deleting these requirements re-deploy your app and it will work.

I am new to Spring Security and Oauth2. In my spring boot application, I have implemented authentication with Oauth2 with following set of changes:
Custom Ouath2 User service is as follows:
...ANSWER
Answered 2021-Dec-08 at 11:45I've created a simplified setup starting from your code with support for both OAuth2 and Basic Auth.
/tenant2/**
will start a basic authentication.
/**
(everything else) triggers an OAuth2 Authorization Code authentication.
The key to achieve this is to have one @Configuration
class per authentication type.
Let's start with the controllers:

QUESTION
I am trying to figure out how to get pod labels into the metric tags from kubelet metrics using prometheus-stack. In our environment, we need to hash pod names (due to length limitations) so our app name, env, and unit name are saved in pod labels.
We are using prometheus-stack (helm installation) to collect metrics from kubelet (/metrics
, /metrics/cadvisor
) and due to the lack of pod labels in metrics tags, it's difficult to know which metric belongs to which application.
Prometheus-stack is using sd_kubernetes_config
with endpoint rule to collect kubelet metrics, where __meta
tags for pod labels cannot be used. Is there another way how to get that labels in metric tags?
I also tried to collect pod_labels metric using kubeStateMetrics
, where I can get metric that contains pod labels, but I cannot figure out how to display both metrics in a way that metric from cadvisor will show its value and metric from kubeStateMetrics
will be used to display its labels (in Prometheus graph).
Thanks for any advice.
...ANSWER
Answered 2021-Dec-02 at 08:39As far as I know you can really use filtering metrics based on pod labels. Look at the original answer:
You can use
+
operator to join metrics. Here,group_left()
will include the extra label:label_source
from the right metrickube_pod_labels
. The metric you're joining is forced to zero ( i.e.0 * kube_pod_labels
) so that it doesn't affect the result of first metric.
