Print the public certificates used by this UCP web server.

## Usage

```
docker container run --rm \
    --name ucp \
    -v /var/run/docker.sock:/var/run/docker.sock \
    docker/ucp \
    dump-certs [command options]
 ```

## Description

This command outputs the public certificates for the UCP web server running on
this node. By default, it prints the contents of the `ca.pem` and `cert.pem` files.

When integrating UCP and DTR, use this command with the `--cluster --ca` flags
to configure DTR.
