- startup scripts don't run for Windows since it is isn't implemented yet. - startup scripts use instance metadata instead of serial port output to flag when they are done. - added licenses to Image data type (to check if an Image is a Windows Image). - added GetImage and GetImageFromProject to googlecompute Drivers. - changed some of the builder/googlecompute tests to use github.com/stretchr/testify/assert. Tests: - (in the Packer directory) `go test .`, `go test ./builder/googlecompute`, and `go test ./post-processor/googlecompute-export` - manual run of `packer build packer_template.json` with the following files --packer_template.json-- { "builders": [ { "type": "googlecompute", "account_file": "creds.json", "project_id": "google.com:packer-test", "source_image": "debian-8-jessie-v20160629", "zone": "us-central1-a", "startup_script_file": "startup_script.sh", "metadata": { "startup-script": "#!/bin/sh\necho \"This should be overwritten.\"", "startup-script-log-dest": "gs://packer-test.google.com.a.appspot.com/startup-script.log" }, "image_name": "test-packer-modifications", "ssh_username": "foo" } ], "post-processors": [ { "type": "googlecompute-export", "paths": [ "gs://packer-test.google.com.a.appspot.com/foo.tar.gz", "gs://packer-test.google.com.a.appspot.com/bar.tar.gz" ], "keep_input_artifact": true } ] } --startup_script.sh-- \#!/bin/sh echo "Hi, my name is Scott. I'm waiting 60 seconds!" >> /scott sleep 60 echo "I'm done waiting!" >> /scott
