How can I run rover while passing tfvars locally

Hello !

Running rover --help explain how to use the tfVar and tfVarsFile, among others.

In order to use a .tfvars file, you an use this command: rover -tfVarsFile /path/to/test.tfvars
Be sure to use the key-value (i.e: name=value) format fot your tfvars file, JSON is not yet parsed corrctly by rover.

In order to convert a JSON into a tfvars, you can use the following snippet:

# Input file
ofile="/path/to/test.tfvars.json"
# Output file
vfile=$(mktemp)

# JSON -> KV variables
cat ${ofile} | \
  jq -r '. as $in | keys[] | [.]+["=\""]+[$in[.]]+["\""] | map(tostring) | add' > \
  ${vfile}

If you are running Rover in Docker, you'll also need to mount the variables file into the container:

vfile="/path/to/test.tfvars"
TERRAFORM_FILES_DIR="/path/to/terraform_files"

docker run \
  --rm \
  -it \
  -p 9000:9000 \
  -v "${vfile}:/vars:ro" \
  -v ${TERRAFORM_FILES_DIR}:/src \
  im2nguyen/rover \
  -tfVarsFile /vars"
