Skip most of kubernetes/preinstall role during late DNS config (#3627) When using resolvconf_mode host_resolvconf, there is an early DNS config stage where Kubernetes cluster DNS is not injected for host DNS intially. Later, the cluster DNS is enabled, but we do not need to run every task from the kubernetes/preinstall role.

Install the latest filesystem creation packages (#3904) This PR ensures that the e2fsprogs and xfsprogs packages are installed on all Kubernetes nodes and that the packages are the latest versions. It also ensures that the nodes can create XFS filesystems when necessary, since not all distros install xfsprogs by default. e2fsprogs - ext2/ext3/ext4 file system utilities xfsprogs - Utilities for managing the XFS filesystem

Implemented cloud-provider integration for OpenStack. Currently kubespray does not install kubernetes in a way that allows cinder volumes to be used. This commit provides the necessary cloud configuration file and configures kubelet and kube-apiserver to use it.

Remove support for CoreOS Container Linux (#6576)
2020-08-28 09:28:53 +00:00
# Flatcar Container Linux by Kinvolk cloud init config file to define /etc/resolv.conf content
Preconfigure DNS stack and docker early In order to enable offline/intranet installation cases: * Move DNS/resolvconf configuration to preinstall role. Remove skip_dnsmasq_k8s var as not needed anymore. * Preconfigure DNS stack early, which may be the case when downloading artifacts from intranet repositories. Do not configure K8s DNS resolvers for hosts /etc/resolv.conf yet early (as they may be not existing). * Reconfigure K8s DNS resolvers for hosts only after kubedns/dnsmasq was set up and before K8s apps to be created. * Move docker install task to early stage as well and unbind it from the etcd role's specific install path. Fix external flannel dependency on docker role handlers. Also fix the docker restart handlers' steps ordering to match the expected sequence (the socket then the service). * Add default resolver fact, which is the cloud provider specific and remove hardcoded GCE resolver. * Reduce default ndots for hosts /etc/resolv.conf to 2. Multiple search domains combined with high ndots values lead to poor performance of DNS stack and make ansible workers to fail very often with the "Timeout (12s) waiting for privilege escalation prompt:" error. * Update docs.
