Initial commit 2015-10-03 20:19:50 +00:00			`---`
Scale-up functionality for etcd cluster * Set ETCD_INITIAL_CLUSTER_STATE from `new` to `existing`, because parameter `new` makes sense only on cluster assembly stage. * If cluster exists and current node is not a part of the cluster, add it with command `etcdctl add member name url`. Closes kubespray/kargo/#270 2016-05-27 09:55:52 +00:00			`- include: set_facts.yml`
etcd directly in host fix etcd configuration for nodes fix wrong calico checksums using a var name etcd_bin_dir fix etcd handlers for sysvinit using a var name etcd_bin_dir sysvinit script review etcd configuration 2016-01-19 14:23:19 +00:00			`- include: install.yml`

Add etcd proxy support * Enforce a etcd-proxy role to a k8s-cluster group members. This provides an HA layout for all of the k8s cluster internal clients. * Proxies to be run on each node in the group as a separate etcd instances with a readwrite proxy mode and listen the given endpoint, which is either the access_ip:2379 or the localhost:2379. * A notion for the 'kube_etcd_multiaccess' is: ignore endpoints and loadbalancers and use the etcd members IPs as a comma-separated list. Otherwise, clients shall use the local endpoint provided by a etcd-proxy instances on each etcd node. A Netwroking plugins always use that access mode. * Fix apiserver's etcd servers args to use the etcd_access_endpoint. * Fix networking plugins flannel/calico to use the etcd_endpoint. * Fix name env var for non masters to be set as well. * Fix etcd_client_url was not used anywhere and other etcd_* facts evaluation was duplicated in a few places. * Define proxy modes only in the env file, if not a master. Del an automatic proxy mode decisions for etcd nodes in init/unit scripts. * Use Wants= instead of Requires= as "This is the recommended way to hook start-up of one unit to the start-up of another unit" * Make apiserver/calico Wants= etcd-proxy to keep it always up Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com> Co-authored-by: Matthew Mosesohn <mmosesohn@mirantis.com> 2016-07-11 14:05:05 +00:00			`when: is_etcd_master`

Set default etcd deployment to docker Improved docker reload command to wait for etcd to be up before proceeding. Switched reload to run restart because it can't reload if it is not guaranteed to be in running state. 2016-07-19 13:45:37 +00:00			`- name: Restart etcd if binary changed`
