client-go | Go client for Kubernetes | Continuous Deployment library

In this documentation one can find the following excerpt:

k8s.io/client-go and tools using it such as kubectl and kubelet are able to execute an external command to receive user credentials. (...)

To authenticate against the API:

• The user issues a kubectl command.
• Credential plugin prompts the user for LDAP credentials, exchanges credentials with external service for a token.
• Credential plugin returns token to client-go, which uses it as a bearer token against the API server.
• API server uses the webhook token authenticator to submit a TokenReview to the external service.
• External service verifies the signature on the token and returns the user's username and groups.

Better answer: as suggested by @Oliver Dain, use zap.AtomicLevel. See their answer for details.

Another option is to create a core with a custom LevelEnabler function. You can use zap.LevelEnablerFunc to convert a closure to a zapcore.LevelEnabler.

The relevant docs:

LevelEnabler decides whether a given logging level is enabled when logging a message.

LevelEnablerFunc is a convenient way to implement zapcore.LevelEnabler with an anonymous function.

That function may then return true or false based on some other variable that changes at runtime:

you can use this package:

"k8s.io/client-go/discovery"

call this function: discovery.NewDiscoveryClientForConfig(cfg) which returns DiscoveryClient object which you can use to call discClient.ServerVersion()

cfg in the above function is the kubeconfig of the cluster that you can provide, which you can get by calling the function: config.GetConfigOrDie() from this package

"sigs.k8s.io/controller-runtime/pkg/client/config"

I have installed using instructions at this link for the Install NGINX using NodePort option.

The problem is that you are using outdated k0s documentation: https://docs.k0sproject.io/v1.22.2+k0s.1/examples/nginx-ingress/

You should use this link instead:
https://docs.k0sproject.io/main/examples/nginx-ingress/

You will install the controller-v1.0.0 version on your Kubernetes cluster by following the actual documentation link.

In a Kubernetes pod you can execute the stat linux command instead of ls command.

I create a pod with label, and then I get it through LabelSelector. Like it :

This commit of jfrog-client-go fixes the issue. jfrog-client-go v1.8.1 was released with this fix.

JFrog CLI 2.12.1 was also released and includes this fix. It appears that the scenario which exposed this bug is a nil response or a response without a body. If this is caused by some instability in your network, there's a chance that jfrog-client-go's HTTP retry mechanism will mitigate and resolve the issue, now that it no longer crashes beicase of it.

It is worth upgrading JFrog CLI to version 2.12.1 (which is currently the latest) and seeing if the issue is completely resolved, or there are other issues, which may or may not be related to the code of JFrog CLI, which still need to be handled.

Kubernetes 1.22 is supported only with NGINX Ingress Controller 1.0.0 and higher = https://github.com/kubernetes/ingress-nginx#support-versions-table

You need tu upgrade your nginx-ingress-controller Bitnami Helm Chart to Version 9.0.0 in Chart.yaml. Then run a helm upgrade nginx-ingress-controller bitnami/nginx-ingress-controller.

You should also regularly update specially your ingress controller, as the version v0.34.1 is very very old bcs the ingress is normally the only entry appoint from outside to your cluster.

Seems like these 2 documentation links are a lie:

• https://docs.okd.io/4.9/installing/installing_sno/install-sno-preparing-to-install-sno.html
• https://docs.okd.io/4.9/installing/installing_sno/install-sno-installing-sno.html

According to these 2 issues:

• https://github.com/openshift/okd/discussions/1012
• https://github.com/openshift/openshift-docs/issues/39759

OKD does not support "installation with Assisted Installer" and these links are "installation with Assisted Installer". Nice waste of time.
