Launching Using Deployment Manager Template

  1. To launch instance using deployment manager, cut/paste and store the following deployment sample in a yaml file. Please be careful in cut-pasting SSH key as any extra whitespace/newline will not let you log into the instance using SSH key. For example, mydeployment.yaml and edit/add fields for your environment such as instance zone, instance type, instance name, networks, subnetworks and so on. You can also add any startup configurations to the config file. The following example adds a user called “testuser” with password “test123” to the launched instance config which is used to login into the instance in addition to the SSH based login.
    Note: Only SSH based GCP authentication is recommended, this is just an example and should not be used in production.

  2. Deploy mydeployment.yaml: 
    $gcloud --project <my_project> deployment-manager deployments create --config mydeployment.yaml
  3. Get the IP address and connect to created instance. 
    
$gcloud --project <my_project> computeinstancesdescribe --zone us-east1-b deploy-arista-three-nic-mgmt
...check the NAT IP address of first interface ...
$ssh -i <my-ssh-priv-key> testadmin@<instance_nat_ip>
