Repository containing Ansible playbooks that will deploy OSS DC/OS

Documentation for dcos-ansible

This repo contains Ansible playbooks that can be used to deploy a DC/OS cluster running the community version of DC/OS.

Dependencies

We assume you at least 4 systems, each of which has CentOS 7.2 or 7.3 installed. This may work on 7.4, however it has not been tested, nor has this been tested on RHEL and will likely not work due to yum repositories that will be added to the cluster to install Docker.

Ansible needs to be installed on the system that will drive the deployment process. For installation instructions, refer to the Ansible install docs found here.

You will need to have an SSH key installed on your remote systems before you proceed with the installation.

Usage

Clone this repository:

git clone https://github.com/dparrish-mesosphere/dcos-ansible.git
cd dcos-ansible

Update the hosts file with the IP addresses or hostnames of the systems you would like to use for your cluster, for example:

[bootstrap]
10.0.0.5

[masters]
10.0.0.100
10.0.0.101
10.0.0.102

[public-agents]
10.0.0.200
10.0.0.201

[private-agents]
10.0.0.150
10.0.0.151
10.0.0.152
10.0.0.153
10.0.0.154

[dcos-cluster:children]
masters
public-agents
private-agents

If you have not already made an ssh connection to your remote systems, you will want to disable Ansible host key checking. This can be done in one of the following ways:

export ANSIBLE_HOST_KEY_CHECKING=False

Or by creating/modifying ~/.ansible.cfg with the following option:

[defaults]
host_key_checking=False

When ready to start installing DC/OS, run the following command:

ansible-playbook -i hosts --private-key <path_to_ssh_key> --extra-vars="dcos_version=dcos-1.10" main.yaml
