tf_os_consul

A Terraform module for creating a Consul cluster on OpenStack (neutron)

The Consul cluster will have cluster_size number of instances with the ssh keypair applied. Assumes security_group_ids allow ports required by Consul (see https://www.consul.io/docs/agent/options.html#ports). Tested with CoreOS Container-Linux.

Input Variables

• os_auth_url - OpenStack API auth url
• public_key_file - Path to ssh public key file
• private_key_file - Path to ssh private key file
• do_bootstrap - 1 to bootstrap cluster or 0 to join to existing cluster - NOTE: this currently only works with value 1 due to issue 14548 (see hashicorp/terraform#14548)
• cluster_size - Number of instances to start for cluster
• region - ID of the OpenStack Region
• image_name - Name of the OpenStack Image for instances
• flavor_name - Name of the OpenStack Flavor for instances
• ssh_key_pair_name - Name of ssh keypair to create in OpenStack
• security_group_ids - ID of OpenStack security group
• network_id - ID of OpenStack network
• env_name_prefix - A unique prefix to keep clusters separate
• consul_version - Version of Consul (tested with 0.8.5)

Outputs

• consul_endpoints - List of IP addresses of Consul cluster instances
