This change requires 'disable_default_service_account=false' in order to
set 'service_account_email'.
This is a guard against an incorrect assumption
that disabling the default service account would mean that no service
account would be used.
The ability to use a service account other than the default was
introduced in #5928. This change adds to that by introducing the
'disable_default_service_account' config option. If true - and
'service_account_email' is not set - Packer will create a GCE VM
with no service account.
This commit allows user to specify the service account they want
to associate with the virtual machine provisionned by setting
the service_account_email field in the config.
It allows to manage permissions of the instantiated VM properly,
using a service account that can be tied up to IAM roles and
permissions.
This change adds an `omit_external_ip` configuration property that, when true,
will cause no external IP address to be associated with the Google Compute
Engine VM provisioned to create an image. When using `omit_external_ip`, you
must also set the `use_internal_ip` configuration property to true.
Addresses #3296
- Startup scripts can be provided through the instance creation metadata field 'startup-script'.
- Script log can be copied to a GCS location by setting the metadata field 'startup-script-log-dest'.
Added Retry method to googlecompute package.
Added GetSerialPortOutput to googlecompute Drivers.
Added StepWaitInstanceStartup (and associated test) which waits for an
instance startup-script to finish.
Changed the instance service account to use the same service account as the one provided in the Packer config template. It was the project default service account.
Tested googlecompute package with 'go test' and also performed builds
with a startup script and without a startup script.
