These config files will get you a 3 node kubernetes cluster with OpenFaaS up and running in under 5 minutes!

Deployment

To build this environment:

1. Source the civo-env.sh and input your username / password from https://www.civo.com/api Note: You'll need to be logged into your Civo account to see the username/password.

2. Update the public_key variable with your SSH public key in cluster.tf.

   variable "public_key"   { default = "ssh-rsa ..." }
   

3. Set the access CIDR in the access_cidr to restrict SSH and OpenFaaS access. Note: Usually your public IP address/32 or 0.0.0.0/0 for everywhere.

   variable "access_cidr"  { default = "0.0.0.0/0" }
   
   

4. Initialise terraform - terraform init

5. Run terraform - terraform apply.

Cleanup

You can leave your cluster running with OpenFaaS and keep experimenting, but if you want to clean-up the environment type in terraform destroy:

$ terraform destroy
