How can I run rover while passing tfvars locally

[pankajshrestha]

Hello,

Very excited to try this out. I have downloaded the file locally in mac and trying to run from root of TF, how can I pass *.tfvars file when running rover?

Looks like there is option for passing some kind of config but did not see example of how pass this.

Appreciate suggestions on this.

Thanks

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"
