Issue: kubectl commands to this endpoint were going through the proxy, I figured it out after running kubectl --insecure-skip-tls-verify cluster-info dump which displayed the proxy html error page.

I just want to share, sorry I wasn't able to provide this earlier as I just realized this is causing. I fixed it by exporting kubelet. For those of you that were late to the thread like I was and none of these answers worked for you I may have the solution:.

When I copied over my. Make sure that you do this and it may fix your problem like it did mine. In case of the error you should export all the kubecfg which contains the certs. This was happening because my company's network does not allow self signing certificates through their network.

Try switching to a different network. This is an old question but in case that also helps someone else here is another possible reason.

Docker login on Gitlab error x509: certificate signed by unknown authority

Let's assume that you have deployed Kubernetes with user x. If the. You need to switch to the user profile so kubernetes can load the configuration from the. So kubectl doesn't trust the cluster, because for whatever reason the configuration has been messed up mine included. To fix this, you can use openssl to extract the certificate from the cluster. I wish I knew what encoding certificate-authority-data uses, but after a few hours of googling I resorted to this solution, and looking back I think it's more elegant anyway.

After the root cert is imported, I can see curl is working fine as it won't complain the cert error, however if I use docker pull I still have the same issue.

Is docker using different ca-cert location than curl? How do I fix the issue with docker pull in this situation? Docker does have an additional location you can use to trust individual registry server CA. Include the port number if you specify that in the image tag, e. In Organizations, the servers usually comes preinstalled with it's own Root Cert. So if you use cert issued by the organization, docker will not be able to find the organization's Root Cert.

Client Version: version. Server Version: version. What happened : I used the below command to create a POD: kubectl create --insecure-skip-tls-verify -f monitorms-rc. Should Kubernetes not ignore the server certificate with that --insecure-skip-tls-verify flag? Assuming you're using a self signed certificate, your CA still needs to get added in your local trust store even if you're using --skip-tls-verify.

I installed the server certificate globally on this kubernetes master node and then restarted the docker service running on it. After that I am successfully able to manually pull that image using docker pull Before that I was getting this error message while doing a manual pull of that image. The error is from Docker daemon while pulling image.

Maybe you should try the command docker pull That is a valid arg to kubectl create but just controls trust between kubectl and the API server. The pull error is between the node and the docker registry. The node either needs to trust the certificate or treat that registry as an untrusted registry which makes the node tolerate TLS verification errors. Hopefully that should do the trick. Actual recorded cases of preventing unauthorized access : ZERO Amount of countless of developer time wasted because of tooling that don't integrate CA certs into their tooling properly: gasmillions of man hours.

Moral of the story. Ditch CA certs. Such a ballache every time you have try to get tooling to work together. Nobody knows how it works. Software that use it never work.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Getting this error when executing any kubectl command: Unable to connect to the server: x certificate signed by unknown authority.

Did some digging around and found that it is because of self signed certificates. My question: how can I get these configuration options added automatically added to the kube-apiserver startup script when I install the cluster with kops? You really shouldn't have to do this. This sounds more like an installation problem when running kops. Were you doing anything unusual? I have been able to reproduce lots of times.

I think it happens when I destroy a cluster and within a few mins, re-create the same cluster again. Finally found the source of this error. Essentially my. It was a bug in my scripts, outside of kops. Now that I have fixed, it, I do not expect to have this error. This will happen is you are intentionally MITMing eg if you are putting your cluster behind an external system that does SSL termination on a different CA then the cluster uses.

Not sure how to deal with this yet. This will happen if you recreate a cluster and you do not copy the new configuration to the regular user. What other info can I provide? It returned the client info version, etc. I've been getting this going through terraform demos on EKS launching from osx, but in theory that shouldn't matter Try doing it over a VPN. Soi performed these steps when I got a certification error.

Otherwise, it will not work. Entering the plaintext cert resolved the issue for me. In my case, I got this error with "kubectl version".

I had installed minikube in my linux machine, and kubectl was configured to use the minikube. It got resolved when I added the minikube server Its just about regenerating the kube config file.

It is a self signed certification, why do I get the error instead of a warning? Docker push and pull failed because of this. Testing with your system chain and curl will be a good indication of whether the certificates are correct and being used by the registry. Docker registry xxxxxxxxx is running in secure mode. I should not able to pull image from it in unsecure mode, right? Insecure mode will still attempt to use TLS, it will just allow certificates from unknown authorities.

Can you send your docker daemon logs and also the link to the docs you used for generating the certificate. Here is my log of testing it out. If you can attempt to do something similar in your environment maybe we can see if this is environment or version issue.

RichardScothern dmcgowan : thanks for the details. I am able to make it work. My docker client is able to push and pull docker images to a secure docker registry now. I have another open issue that I am not able to make it work with use HAProxy as a frontend load balancer to pass through the traffic to Docker registries after enabling SSL in the docker registries.We have some users who are trying to push Docker containers in to a Gitlab registry and their push is being rejected because of an invalid certificate.

This was working last week before doing yum update, upgrading from Gitlab There was a secondary issue as well that started happening, normal users trying to check out code were now forced to use SSL which is what we want. So I assumed it was the WeEncrypt certificate not working for some reason, and replaced it with our wildcard certificate. I did some tests using curl. Basically it seems that the SSL certificate settings on Gitlab needed to be changed. I need to make sure both the registry and the repo were using a pem file.

Ensure you have the following lines, I added mine at the bottom after all the commented out examples just so I can see all my settings in a common location. Share Tweet Share Email Kubernetes 1.
