This issue was originally opened by @rbellamy as hashicorp/packer#9230. It was migrated here as a result of the Packer plugin split. The original body of the issue is below.
Overview of the Issue
Shell provisioner with docker builder sets wrong UID:GID for script.
Packer is run by UID:GID of 1001:1001.
Packer shell provisioner script in Docker is mode 0600 and UID:GID of 1001:1001.
Packer Docker builder uses exec_command of 1000:1000.
Error is permission denied when provisioner attempts to execute script.
When the UID:GID of the user running packer is the same as that set for the exec_command there are no permission denied errors.
