displague/linode-terraform-demo repository overview

⁠Linode Terraform Provider in a Container

This repository contains a Dockerfile and a basic set of Terraform configuration files that demonstrate the Linode Terraform Provider.

The image is based on the hashicorp/terraform:full image, adding only the Linode provider.

Terraform variables can be defined in config files, using the command-line, or using environment variables. For the purposes of this demo container, environment variables will be supplied through docker -e arguments. We will also attach the local copy of this repository to the container.

⁠Name the Container

DOCKER_IMAGE=displague/linode-terraform-demo

⁠Build the Container (Optional)

docker build . -t $DOCKER_IMAGE

⁠Setup the Environment for the Container

read -sp "Linode Token: " LINODE_TOKEN; echo
export TF_VAR_root_pass="$(openssl rand -base64 32)"
export TF_VAR_authorized_key="$(cat ~/.ssh/id_rsa.pub)"
export TF_VAR_linode_token="$LINODE_TOKEN"

⁠Run the Container

Finally, let's run terraform from the container.

alias dockertf='docker run  -v `pwd`/:/terraform -it -e TF_VAR_root_pass="$TF_VAR_root_pass" -e TF_VAR_authorized_key="$TF_VAR_authorized_key" -e TF_VAR_linode_token="$TF_VAR_linode_token" $DOCKER_IMAGE'
dockertf plan
dockertf apply

You will notice that .terraform now contains more files.

⁠Destroy the created Linode Instances

dockertf destroy

⁠Enter the Container

To dive deeper into this demo,

docker run -it --entrypoint /bin/bash displague/linode-terraform-demo
