OpenDCOS in Triton

Collection of Terraform configuration files and Ansible playbooks for setting up OpenDCOS in Triton.

Requirements

• Ansible (>= 2.0.0.2)
• Terraform (>= 0.6.14)
• Ruby (>= 2.0.0)

How to use it?

Clone this repository with

git clone https://github.com/ContainerSolutions/dcos-in-triton.git

Then you will need to setup some environment variables with your Triton credentials, including your account, SSH key id and the path to the SSH key:

$ export TF_VAR_account=accountname
$ export TF_VAR_key_id=yourkeyid
$ export TF_VAR_key_path=/path/to/ssh/key # (defaults to ~/.ssh/id_rsa)

Be sure to use the MD5 hash of the SSH key for the TF_VAR_key_id variable; not the SHA256 hash. The SHA256 hash is the default printed out by ssh-keygen in OpenSSH 6.8 and newer. Both MD5 and SHA256 formats are accepted by the node-triton tools. If you have these tools installed, there is a good chance that you have the TRITON_KEY_ID environment variable set to the SHA256 value for your SSH key.

You can generate the MD5 fingerprint for a SSH key by using the following flags with ssh-keygen

$ ssh-keygen -l -E md5 -f  ~/.ssh/id_rsa.pub
2048 MD5:db:95:dd:3d:dd:6e:52:69:21:96:2a:46:4a:8d:21:7e [email protected] (RSA)

In this example, the SSH key id (fingerprint) is db:95:dd:3d:dd:6e:52:69:21:96:2a:46:4a:8d:21:7e.

For comparision, the SHA256 fingerprint will appear as follows:

ssh-keygen -l  -f  ~/.ssh/id_rsa.pub
2048 SHA256:8lJK34wkvadR5LNMj5WY4xFktFl/Q5UGcuKBtya9oO4 [email protected] (RSA)

You can check out the Terraform plan with:

$ terraform plan

Create the infrastructure in Triton with the following command:

$ terraform apply

Once Terraform is done creating your infrastructure, apply the Ansible roles running the init.yml playbook like so:

$ ansible-playbook -i plays/inventory/terraform plays/init.yml

Finally, find the IP of your DCOS master node by running

./plays/inventory/terraform

Access that IP on your browser and follow the instructions.

Enjoy!
