kandi X-RAY | coreos-kubernetes Summary

coreos-kubernetes is a Shell library typically used in Devops, Continuous Deployment, Docker applications. coreos-kubernetes has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

This repo is not in alignment with current versions of Kubernetes, and will not be active in the future. The CoreOS Kubernetes documentation has been moved to the tectonic-docs repo, where it will be published and updated. For tested, maintained, and production-ready Kubernetes instructions, see our Tectonic Installer documentation. The Tectonic Installer provides a Terraform-based Kubernetes installation. It is open source, uses upstream Kubernetes and can be easily customized. This repo contains tooling and documentation around deploying Kubernetes using CoreOS Container Linux. Initial setup of a Kubernetes cluster is covered, but ongoing maintenance and updates of the cluster is not addressed. If you're looking for kube-aws, it has been moved to a new dedicated repository. All outstanding AWS-related issues and PRs should be moved to there. This repository will continue to host development on single and multi node vagrant distributions.

            Fresh Install Kubernetes worker nodes never become "Ready"
            Asked 2017-Jun-12 at 14:51

            I've been battling a kubernetes install problem. We started up a new openstack environment and the scripts that work in the old fail environment fail in the new one.

            We are using K8s v1.5.4 using these scripts: https://github.com/coreos/coreos-kubernetes/tree/master/multi-node/generic

            CoreOS 1298.7.0

            The master seems to come up fine. I can deploy pods to it, always shows ready when running kubectl get nodes

            The worker installation script runs, however it never shows a ready state.

            You need to check if you add your IP address in the SSL generation file (openssl.cnf) for the master. Try to recreate your certificate with the IP of your dns server too ( if you follow coreOS it's 10.3.0.1 ). Your openssl.cnf will look like this:

            Kubernetes: how to enable API Server Bearer Token Auth?
            Asked 2017-Mar-28 at 18:22

            I've been trying to enabled token auth for HTTP REST API Server access from a remote client.

            I installed my CoreOS/K8S cluster controller using this script: https://github.com/coreos/coreos-kubernetes/blob/master/multi-node/generic/controller-install.sh

            My cluster works fine. This is a TLS installation so I need to configure any kubectl clients with the client certs to access the cluster.

            I think your kube-apiserver dies because it's can't find the /etc/kubernetes/token. That's because on your deployment the apiserver is a static pod therefore running in a container which in turn means it has a different root filesystem than that of the host.

            Look into /etc/kubernetes/manifests/kube-apiserver.yaml and add a volume and a volumeMount like this (I have omitted the lines that do not need changing and don't help in locating the correct section):

            kube-dns has a readiness probe that tries resolving trough the Service IP of kube-dns. Is it possible that there is a problem with your Service network?

            I'd check journalctl -xe on the host where calico-node is failing to start. Since you get nothing from kubectl logs calico-node... it sounds like the containers are failing to even start up.

            hyperkube doesn't start any manifest from /etc/kubernetes/manifests
            Asked 2017-Mar-04 at 15:05

            I have Container Linux by CoreOS alpha (1325.1.0) Installed on a pc at home.

            I played with kubernetes for a couple of month, but now after reinstalling ContainerOS and trying to install kubernetes using my fork at https://github.com/kfirufk/coreos-kubernetes I fail to properly install kubernetes.

            I use hyperkube image v1.6.0-beta.0_coreos.0.

            the problem is that it seems that hyperkube doesn't try to initiate any manifests from /etc/kubernetes/manifests. I configured kubelet to run with rkt.

            when I run journalctl -xef -u kubelet after restarting kubelet, I get the following output:

            thanks to @AntoineCotten the problem was easily resolved.

            first, I downgraded hyperkube from v1.6.0-beta.0_coreos.0 to v1.5.3_coreos.0. then I noticed an error in the kubelet log that made me understand that I had a major typo in /opt/bin/host-rkt.

            I had exec nsenter -m -u -i -n -p -t 1 -- /usr/bin/rkt "\$@" instead of exec nsenter -m -u -i -n -p -t 1 -- /usr/bin/rkt "$@".

            I escaped the $ when trying to paste the command line arguments, which then.. didn't. so.. not using 1.6.0-beta0 for now, that's ok! and fixed the script. now everything works again. thanks
