 The container exposes its data directory, `/consul/data`, as a [volume](https://docs.docker.com/engine/tutorials/dockervolumes/). This is where Consul will store its persisted state.

 For servers, this stores the client information plus snapshots and data related to the consensus algorithm and other state like Consul's key/value store and catalog. **Servers need the volume's data to be available when restarting containers to recover from outage scenarios.** Therefore, care must be taken by operators to make sure that volumes containing consul cluster data are not destroyed during container restarts,

 You will need to tell Consul what its cluster address is when starting so that it binds to the correct interface and advertises a workable interface to the rest of the Consul agents.  There are two ways of doing this:

 2. Address Templates: You can declaratively specify the client and cluster addresses using the formats described in the [go-socketaddr](https://github.com/hashicorp/go-sockaddr) library.
 In the following example, the client and bind addresses are declaratively specified for the container network interface 'eth0'
 
     ```sh
     $ docker run \
