Concourse Packer Resource

Based off the cycloidio/concourse-packer-resource fork of Snapkitchen/concourse-packer-resource.

A concourse-ci resource for building images via Packer.

behaviour

check: not implemented

in: not implemented

out: validate a template, or template and config directory, or build a new instance artifact

parameters

• template: required. the path to the packer template file or directory.

• objective: optional. the packer objective for the template; either validate or build triggers corresponding additional actions. default: validate

• env_vars: optional. dict of variables to set in the environment.

• env_vars_from_files: optional. dict of vars and file paths to set in the environment.

• var_files: optional. the list of paths to external JSON variable file(s).

• vars: optional. dict of explicit packer variable key/value pairs.

• vars_from_files: optional. dict of vars and file paths to use as their value.

• only: optional. list of sources on which to perform the action (mutually exclusive with excepts)

• excepts: optional. list of sources on which to not perform the action (mutually exclusive with only)

• force: optional. set to true to enable the force option during a packer build. default: false

• debug: optional. set to true to dump argument values and parsed output. may result in leaked credentials. default: false

the id of the first artifact produced will be used as the version, with the full artifact details in the output metadata

note: in an effort to prevent credentials leaking to logs, the full packer command line will not be printed on failure -- however, you should still mark any relevant variables as sensitive variables in the packer template to prevent packer from printing them in log output

the packer executable will have a working directory of the concourse input directory, so file paths can be relative to resources, or absolute paths
