Linux kernel 3.10 or later with required dependencies. The following distributions have the required kernel, its dependencies, and are known to work well with Calico and host protection.
- RedHat Linux 7

Calico v3.1 requires a key/value store accessible by all Calico components. The key/value store must be etcdv3.
Calico requires the network to allow the following types of traffic.
* Our manifests enable IPIP by default. If you disable IPIP, you won’t need to allow IPIP traffic. Refer to Configuring IP-in-IP for more information.
Tip: On GCE, you can allow this traffic using firewall rules. In AWS, use EC2 security group rules.
Tip: If you are using one of the recommended distributions, you will already satisfy these.
