vetlekise commented 3 weeks ago

Info

terraform-setup: v3.x.x
Runner OS: Ubuntu 22.04.3 LTS

Problem

Terraform init fails on GitHub self-hosted runner ONLY when its running as a service, if I run the script ./actions-runner/run.sh it works without any issues.

Error

Run terraform init -backend-config="storage_account_name=$STORAGE_ACCOUNT" -backend-config="container_name=$CONTAINER_NAME" -backend-config="resource_group_name=$RESOURCE_GROUP_NAME" -backend-config="key=$BLOB_KEY_NAME"

      with:
        terraform_wrapper: true

What's tested?

All the v3.x.x versions.

What works?

v2 works no problem.

Just found this earlier issue having the same error message and it got solved by setting the terraform_wrapper: to false.

Just tested this myself and it worked, but I unfortunately need the wrapper for the PR comment to work using the action actions/github-script@v7

Found this other issue telling them to use node 20 for terraform-setup v3. But the runner already had this installed as node -v showed me v20.18.0... I then ran sudo apt upgrade and I saw some error about a node 18 package.

I fixed it by running these commands:

sudo apt remove --purge nodejs BAD_PACKAGE
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs
