Container install

If you want to run under Docker, you can use calicoctl node run --node-image=quay.io/calico/node:v3.4.0 to start the calico/node container image. This container packages up the core Calico components to provide both Calico networking and network policy. Running the container automatically pre-initializes the etcd database (which the other installations methods do not). See the calicoctl node run guide for details.
