This build step invokes HashiCorp Packer in Google Cloud Build.
Arguments passed to this builder will be passed to packer directly, allowing callers to
run any Packer command.
Before using this builder in a Cloud Build config, it must be built and pushed to the registry in your project. Run the following command in this directory:
gcloud builds submit .
Advanced builder building: To specify a particular version of Packer, provide the Packer version number and the checksum of that version's linux/amd64 zip archive as Cloud Build substitutions:
gcloud builds submit --substitutions=_PACKER_VERSION=1.9.1,_PACKER_VERSION_SHA256SUM=793ed62255b9e572eda0c77d2a770f5fde501314b7598320786f1e51feb260d6 .
You can securely pass credentials to packer using encrypted files.
See examples in the examples subdirectory.
