Bootstrap faasd with TLS support on Digitalocean

  1. Sign up to DigitalOcean

  2. Download Terraform

  3. Clone this gist using the URL from the address bar

  4. Run terraform init

  5. Configure terraform variables as needed by updating the main.tfvars file:

    Variable Description Default
    do_token Digitalocean API token None
    do_domain Public domain used for the faasd gateway None
    do_subdomain Public subdomain used for the faasd gateway faasd
    letsencrypt_email Email used by when ordering TLS certificate from Letsencrypt ""
    do_create_record When set to true, a new DNS record will be created. This works only if your domain (do_domain) is managed by Digitalocean false
    do_region Digitalocean region for creating the droplet fra1
    ssh_key_file Path to public SSH key file ~/.ssh/id_rsa.pub

Environment variables can also be used to set terraform variables when running the terraform apply command using the format TF_VAR_name.

  1. Run terraform apply

    1. Add -var-file=main.tfvars if you have set the variables in main.tfvars.
    2. OR use environment variables for setting the terraform variables when running the apply command

  2. View the output for the login command and gateway URL i.e.

droplet_ip = 178.128.39.201
gateway_url = https://faasd.example.com/
  1. View the output for sensitive data via terraform output command
terraform output login_cmd
login_cmd = faas-cli login -g http://178.128.39.201:8080/ -p rvIU49CEcFcHmqxj

terraform output password
password = rvIU49CEcFcHmqxj
  1. Use your browser to access the OpenFaaS interface

Note that the user-data may take a couple of minutes to come up since it will be pulling in various components and preparing the machine. Also take into consideration the DNS propagation time for the new DNS record.

A single host with 1GB of RAM will be deployed for you, to remove at a later date simply use terraform destroy.
