Add flannel vars to enable vagrant and amazon environments 2016-01-23 18:27:06 +00:00			`---`
Add variables and defaults for multiple types of ip addresses. Each node can have 3 IPs. 1. ansible_default_ip4 - whatever ansible things is the first IPv4 address usually with the default gw. 2. ip - An address to use on the local node to bind listeners and do local communication. For example, Vagrant boxes have a first address that is the NAT bridge and is common for all nodes. The second address/interface should be used. 3. access_ip - An address to use for node-to-node access. This is assumed to be used by other nodes to access the node and may not be actually assigned on the node. For example, AWS public ip that is not assigned to node. This updates the places addresses are used to use either ip or access_ip and walk up the list to find an address. 2016-01-26 20:41:42 +00:00			`# Flannel public IP`

Initial version of Flannel using CNI (#1486) * Updates Controller Manager/Kubelet with Flannel's required configuration for CNI * Removes old Flannel installation * Install CNI enabled Flannel DaemonSet/ConfigMap/CNI bins and config (with portmap plugin) on host * Uses RBAC if enabled * Fixed an issue that could occur if br_netfilter is not a module and net.bridge.bridge-nf-call-iptables sysctl was not set 2017-08-25 07:07:50 +00:00			`# Disabled until https://github.com/coreos/flannel/issues/712 is fixed`

But different nodes can have different interface names for the inter-host communication network The option --iface-regex allows the flannel to find the interface on which the address is set from the inter-host communication network 2018-03-16 18:44:36 +00:00			`## This is actually an inventory cluster-level item`

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.
