Bursting into Azure from AWS

In the previous lab we've configured a cluster with small # of DC/OS instances. In this lab we will increase the # of nodes on one of the cloud providers (Azure) to simulate bursting and expanding capacity to the cloud

Adding or Removing Remote Nodes or Default Region Nodes

Change the number of remote nodes in the desired cluster profile.

  1. Open your desired_cluster_profile.tfvars
  2. Change the following variables

  • aws_group_{n}_private_agent_az from 1 to 3 (per zone)

  • number of aws_group_{n}_public_agent_az from 1 to 3

  • num_of_azure_private_agents from 1 to 5

At the end of your change it should look like this:

dcos_version = "1.12.1"
num_of_masters = "1"
aws_region = "us-east-1"
aws_master_instance_type = "m4.xlarge"
aws_agent_instance_type = "m4.xlarge"
aws_public_agent_instance_type = "m4.xlarge"
aws_private_agent_instance_type = "m4.xlarge"
aws_bootstrap_instance_type = "m4.xlarge"
# ---- Private Agents Zone / Instance
aws_group_1_private_agent_az = "a"
aws_group_2_private_agent_az = "b"
aws_group_3_private_agent_az = "c"
num_of_private_agent_group_1 = "3"
num_of_private_agent_group_2 = "3"
num_of_private_agent_group_3 = "3"
# ---- Public Agents Zone / Instance
aws_group_1_public_agent_az = "a"
aws_group_2_public_agent_az = "b"
aws_group_3_public_agent_az = "c"
num_of_public_agent_group_1 = "0"
num_of_public_agent_group_2 = "0"
num_of_public_agent_group_3 = "1"
# ----- Remote Region Below
azure_region = "UK South"
num_of_azure_private_agents = "5"
num_of_azure_public_agents  = "1" 
azure_public_agent_instance_type = "Standard_D3_v2"
azure_agent_instance_type = "Standard_D3_v2"
azure_bootstrap_instance_type = "Standard_D3_v2"
# ----- DCOS Config Below
dcos_cluster_name = "Hybrid-Cloud"
aws_profile = "110465657741_Mesosphere-PowerUser"
dcos_license_key_contents = "<INSERT_LICENSE_HERE>"
ssh_pub_key = "<INSERT_SSH_PUB_KEY>"
  1. Save the file and now you can burst out by performing the terraform apply <args> below:
terraform apply -var-file desired_cluster_profile.tfvars
