DC/OS Ansible based remote exec install

This module installs all DC/OS node types via a set of Ansible roles, invoked from an Docker image.

Prerequisites

• Docker available on bootstrap node
• Access to Dockerhub. Alternatively the mesosphere/dcos-ansible-bundle Docker image can be made available by other means.
• The boostrap node is able to ssh into the other nodes, either via SSH-Agent forwarding or a statically deployed key.

Re-running Ansible for upgrading or config updates

terraform taint -module dcos-install null_resource.run_ansible_from_bootstrap_node_to_install_dcos
terraform apply

EXAMPLE

 module "dcos-install" {
   source = "dcos-terraform/dcos-install-remote-exec-ansible/null"
   version = "~> 0.2.0"

   bootstrap_ip                = "${module.dcos-infrastructure.bootstrap.public_ip}"
   bootstrap_private_ip        = "${module.dcos-infrastructure.bootstrap.private_ip}"
   master_private_ips          = ["${module.dcos-infrastructure.masters.private_ips}"]
   private_agent_private_ips   = ["${module.dcos-infrastructure.private_agents.private_ips}"]
   public_agent_private_ips    = ["${module.dcos-infrastructure.public_agents.private_ips}"]

   dcos_config_yml = <<EOF
