Calico

Configure Calico components for the Master host.

Requirements

Ansible 2.2

Installation

To install, set the following inventory configuration parameters:

openshift_use_calico=True
openshift_use_openshift_sdn=False
os_sdn_network_plugin_name='cni'

For more information, see Calico's official OpenShift Installation Documentation

Improving security with BYO-etcd

By default, Calico uses the etcd set up by OpenShift. To accomplish this, it generates and distributes client etcd certificates to each node. Distributing these certs across the cluster in this way weakens the overall security, so Calico should not be deployed in production in this mode.

Instead, Calico can be installed in BYO-etcd mode, where it connects to an externally set up etcd. For information on deploying Calico in BYO-etcd mode, see Calico's official OpenShift Installation Documentation

Calico Configuration Options

Additional parameters that can be defined in the inventory are:

| Environment | Description | Schema | Default |
|---------|----------------------|---------|---------| | CALICO_IPV4POOL_IPIP | IPIP Mode to use for the IPv4 POOL created at start up. | off, always, cross-subnet | always | | CALICO_LOG_DIR | Directory on the host machine where Calico Logs are written.| String | /var/log/calico |
