Rework systemd service units * Add for docker system units: ExecReload=/bin/kill -s HUP $MAINPID Delegate=yes KillMode=process. * Add missed DOCKER_OPTIONS for calico/weave docker systemd unit. * Change Requires= to a less strict and non-faily Wants=, add missing Wants= for After=. * Align wants/after in a wat if Wants=foo, After= has foo as well. * Make wants/after docker.service to ask for the docker.socket as well. * Move "docker rm -f" commands from ExecStartPre= to ExecStopPost=. hooks to ensure non-destructive start attempts issued by Wants=.

Move docker systemd unit creation to docker role Creating the unit using default settings early on and then changing it during network_plugin section leads to too many docker restarts and duplicated code. Reversed Wants= dependence on docker.service so it does not restart docker when reloading systemd Consolidated all docker restart handlers. 2016-08-02 10:42:27 +00:00			`Wants=docker.socket calico-node.service`

Address standalone kubelet config case Also place in global vars and do not repeat the kube_*_config_dir and kube_namespace vars for better code maintainability and UX.

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. 2016-03-29 12:50:22 +00:00			`$KUBELET_NETWORK_PLUGIN \`

Systemd units, limits, and bin path fixes * Add restart for weave service unit * Reuse docker_bin_dir everythere * Limit systemd managed docker containers by CPU/RAM. Do not configure native systemd limits due to the lack of consensus in the kernel community requires out-of-tree kernel patches.

Deploy kubelet and kube-apiserver as containers kubelet via docker kube-apiserver as a static pod Fixed etcd service start to be more tolerant of slow start. Workaround for kube_version to stay in download role, but not download an files by creating a new "nothing" download entry. 2016-07-08 09:59:21 +00:00			`Restart=always`
