DC/OS is the commercialized Mesos distribution + extras maintained by Mesosphere. I found it very straight forward to setup in GCP with the out of the box Ansible scripts provided by Mesosphere.

For starters I followed everything described in the README.

Then, I had to modify the group_vars/all file in the playbook

project: <my-gcp-project-id>
subnet: default
login_name: <my-gcp-login-id-with-no-email>
bootstrap_public_ip: # This IP need to match the network in the zone
zone: us-central1-c

master_boot_disk_size: 200 # 200 is the recommended in GCP as of 05-2017
master_machine_type: n1-standard-1
master_boot_disk_type: pd-standard

agent_boot_disk_size: 200
agent_machine_type: n1-standard-1
agent_boot_disk_type: pd-standard
agent_instance_type: "MIGRATE"
agent_type: private
start_id: 0001
end_id: 0001

gcloudbin: gcloud
image: 'centos-7-v20161027'
image_project: 'centos-cloud'
bootstrap_public_port: 8080
cluster_name: cluster_name
scopes: "default=https://www.googleapis.com/auth/cloud-platform"
dcos_installer_filename: dcos_generate_config.sh
dcos_installer_download_path: "https://downloads.dcos.io/dcos/stable/{{ dcos_installer_filename }}"
home_directory: "/home/{{ login_name }}"
downloads_from_bootstrap: 2
dcos_bootstrap_container: dcosinstaller

Then to create the master I ran:

ansible-playbook -i hosts install.yml


and to create the agents or slaves I ran (for public facing ones):

ansible-playbook -i hosts add_agents.yml --extra-vars "start_id=0001 end_id=0002 agent_type=public"


If you want to create private agents or slaves you can run something like:

ansible-playbook -i hosts add_agents.yml --extra-vars "start_id=0001 end_id=0002 agent_type=private"


Then you can hit the DC/OS UI with the master’s IP address over HTTPS (Make sure you open up port 443 to your IP address).
