Hi
I'm trying to get GCE Authentication working with packer inside a docker container. Currently, I'm creating a build container based on Debian 9.4 and to this container I add packer and gcloud. The installs go fine as does the gcloud init. But, the only way I get 'packer build' commands to succeed is if I use -var account_file=path/to/my/service_account.json on the command line too. I'd like to set things up in my container to not require passing the account file location in on command line or to hard code the path to the file in my packer.json config file. I know this is possible, as it works on my laptop and other places, but for some reason not in docker. Any suggestions?
Thanks,
Dave
