Download version of terraform in atlantis.yaml

Hello,

It would be awesome if we didnt have to install the version of terraform present in the atlantis.yaml file , but instead having atlantis download the version specified and use it.

Cheers

That's a great idea! I love it.

It should be pretty trivial to do (I do this currently in jenkins via wget and unzip):

# setup terraform version
TFVER="0.11.7" # change me if needed
wget --no-clobber https://releases.hashicorp.com/terraform/"$TFVER"/terraform_"$TFVER"_linux_amd64.zip
unzip terraform_"$TFVER"_linux_amd64.zip
export TERRAFORM_PATH="$(pwd)/terraform"
"$TERRAFORM_PATH" --version

I am also working on a chef cookbook to manage all the things atlantis related and you can find similar logic here for URL building to download: https://github.com/majormoses/atlantis-chef/blob/8edc22005f4bf42d09eb7eeaf01c1599980ce487/libraries/helpers.rb#L32-L35
