However, you can specify which IP pools to use for IP address management in the CNI network config, When using Calico IPAM, IP addresses are assigned from IP Pools.īy default, all enabled IP pools are used. See Configuring the Calico CNI plugins for more information. The log level can be configured via the CNI network configuration file, by changing the value of the For deployments using systemd, you can do this via journalctl. Where these logs end upĭepend on how your kubelet is configured. The Calico CNI plugin emits logs to stderr, which are then logged out by the kubelet. Not be created, and Calico policy will not be enforced. Without the above volume mounts, the kubelet will not call the Calico CNI binaries, and so Plugins and config that have been installed by mounting them into the kubelet container.įor example add the following arguments to the kubelet-wrapper service: You need to make sure that the containerized kubelet can see the CNI network When running the kubelet as a container using hyperkube as is common on CoreOS Container Linux, Byĭefault it places binaries in /opt/cni/bin and config /etc/cni/net.d. Kubernetes node in a directory on the host as specified in the manifest.

Why isn’t Calico working on CoreOS Container Linux / hyperkube?Ĭalico hosted install places the necessary CNI binaries and config on each Subnet-local gateways is fairly common in WAN networking. While the routing table may look a little odd to someone who is used toĬonfiguring LAN networking, using explicit routes rather than Link-local address, Calico saves precious IP addresses and avoidsīurdening the user with configuring a suitable address. In container deployments, Calico usesġ69.254.1.1 as the address for the Calico router. In a Calico network, each host acts as a gateway router for the

Why does my container have a route to 169.254.1.1? Not all orchestrators that we integrate with support IPv6 yet. Yes! Calico’s core components support IPv6 out of the box.
