How do I save the output variable from terragrunt apply as regular shell environment variable?

After running my terragrunt apply-all in my CI step (so basically a bash script) I get my outputs, in this case I only have one:

output "cloudrun-hostname" { value = google_cloud_run_service.cloudrun.status[0].url description = "API endpoint URL"
}

How do I pass the value of that output to the environment variable so basically like I exported a variable like this:

export HOSTNAME=terragrunt-cloudrun-hostname-output

I need this variable with that value so I can envsub the value in another file later.

You can use the terraform output command, i.e.

export MY_ENV=$(terraform output cloudrun-hostname)

after your apply-all.

You will need to expand the command and so:

export HOSTNAME="$(terragrunt apply-all | awk -F= '/value/ { gsub(" ","",$2);print $2 }')"
