# Bootstrap faasd with TLS support on Digitalocean
|
|
|
|
1) [Sign up to DigitalOcean](https://www.digitalocean.com/?refcode=2962aa9e56a1&utm_campaign=Referral_Invite&utm_medium=Referral_Program&utm_source=CopyPaste)
|
|
2) [Download Terraform](https://www.terraform.io)
|
|
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`.
|
|
|
|
6) Run `terraform apply`
|
|
1) Add `-var-file=main.tfvars` if you have set the variables in `main.tfvars`.
|
|
2) OR [use environment variables](https://www.terraform.io/docs/commands/environment-variables.html#tf_var_name) for setting the terraform variables when running the `apply` command
|
|
|
|
7) View the output for the login command and gateway URL i.e.
|
|
|
|
```
|
|
droplet_ip = 178.128.39.201
|
|
gateway_url = https://faasd.example.com/
|
|
```
|
|
|
|
8) View the output for sensitive data via `terraform output` command
|
|
|
|
```bash
|
|
terraform output login_cmd
|
|
login_cmd = faas-cli login -g http://178.128.39.201:8080/ -p rvIU49CEcFcHmqxj
|
|
|
|
terraform output password
|
|
password = rvIU49CEcFcHmqxj
|
|
```
|
|
|
|
|
|
9) 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`.
