Deploying calico on docker

Project Calico provides a layer 3 network implementation,
aimed at scalable datacenter deployments. Compared to
traditional network overlays, Calico provides a more efficient
implementation with minimal packet encapsulation. This allows
better usage of node resources and a simple yet powerful
network stack for your infrastructure.
Calico can be deployed in Docker easily
Calico implements a Docker network plugin that can be used to
provide routing and advanced network policy for Docker
containers.

This slides will guide you to configure a Docker with
Calico networking.
Calico runs as a Docker container on each host
and calicoctl command line tool can be used to launch
the calico/node container.

First step is to download the calicoctl binary:

Next step is to Configure access to our etcd cluster,
calicoctl - etcd datastore and then launch calico/node.
calicoctl will use the specified keys directly on the host
to access etcd, it will also pass on these environment
variables and volume mount the keys into the started
calico-node container:

Let’s now check that calico/node is now running: :

We can also check if the calico/node container is
functioning properly with the following command:

So to print the command calicoctl node run uses to
launch Calico on this host, run the command with
the --init-system and --dry-run flags:
