  • monitoring
  • user data (copy and paste the following):

      #cloud-config
      
      package_upgrade: true
      
      packages: [ "python", "python-pip", "git", "zip", "jq" ]
      
      runcmd:
        - [curl, -o, /tmp/terraform.zip, "https://releases.hashicorp.com/terraform/0.11.10/terraform_0.11.10_linux_amd64.zip"]
        - [unzip, -d, /usr/local/bin/, /tmp/terraform.zip]
        - [curl, -L, -o, /tmp/terraform-inventory.zip, "https://github.com/adammck/terraform-inventory/releases/download/v0.7-pre/terraform-inventory_v0.7-pre_linux_amd64.zip"]

        - [git, clone, "https://github.com/cryptokube-io/devcon4-workshop.git", "/root/devcon4-workshop"]
                    

• SSH keys: select yours
• Hostname: devcon4-mgmt
• Click Create

Management Host Setup

1. Copy IP address of devcon4-mgmt from DigitalOcean control panel
2. SSH into management host:

   ssh root@<IP_ADDRESS>

3. Monitor cloud-init progress (ctrl+c to exit):

     tail -f /var/log/cloud-init-output.log
     # wait ~5 minutes, until log stops with "Cloud-init ... finished at ..."
               

4. Enable Terraform tab-completion:

   terraform -install-autocomplete

   (must re-login or start new shell)
5. Enter workshop directory:

   cd devcon4-workshop

6. Run initialization script:

   bin/init_config
