- Install terraform
Mac: brew install terraform
Linux:
wget https://releases.hashicorp.com/terraform/0.11.7/terraform_0.11.7_linux_amd64.zip
unzip terraform_0.11.7_linux_amd64.zip
sudo mv terraform /usr/local/bin
terraform --version
- Create terraform.tfvars
You will need to create a new file in the root of this repo called terraform.tfvars
which configures variables used to install faas-ecs
| Name | Description |
|---|---|
| aws_region | The aws region to create the openfaas ecs cluster in |
| debug | 1 to create an ec2 bastion in the external subnet and a test instance in the internal subnet |
| developer_ip | your ip address, used to whitelist incoming ssh to bastion |
Example file
cat > ./terraform.tfvars <<EOF
aws_region = "eu-west-1"
debug = "0"
developer_ip = "217.46.68.185"
EOF
- Create a public key for ssh
Ssh access is only required if debug = "1", however the ssh key is still required for the
install to work even if debug disabled. To create the key run:
make keys
- Run terraform
make

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.
Please just re-run make, this is an eventual consistency problem see #4
- Run
make uninstall - Patiently wait about
5-10 minutes
