dockerfile-parser

Used to parse Dockerfile build specs to infer their dependencies.

Backend: pants.backend.docker
Config section: [dockerfile-parser]

Basic options

None

Advanced options

`version`

--dockerfile-parser-version=<str>
PANTS_DOCKERFILE_PARSER_VERSION

default: dockerfile==3.2.0

Requirement string for the tool.

`extra_requirements`

--dockerfile-parser-extra-requirements="['<str>', '<str>', ...]"
PANTS_DOCKERFILE_PARSER_EXTRA_REQUIREMENTS

default: []

Any additional requirement strings to use with the tool. This is useful if the tool allows you to install plugins or if you need to constrain a dependency to a certain version.

`interpreter_constraints`

--dockerfile-parser-interpreter-constraints="['<str>', '<str>', ...]"
PANTS_DOCKERFILE_PARSER_INTERPRETER_CONSTRAINTS

default:

[
  "CPython>=3.7,<4"
]

Python interpreter constraints for this tool.

`lockfile`

--dockerfile-parser-lockfile=<str>
PANTS_DOCKERFILE_PARSER_LOCKFILE

default: <default>

Path to a lockfile used for installing the tool.

Set to the string <default> to use a lockfile provided by Pants, so long as you have not changed the --version and --extra-requirements options, and the tool's interpreter constraints are compatible with the default. Pants will error or warn if the lockfile is not compatible (controlled by [python].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.12.1/src/python/pants/backend/docker/subsystems/dockerfile.lock for the default lockfile contents.

Set to the string <none> to opt out of using a lockfile. We do not recommend this, though, as lockfiles are essential for reproducible builds.

To use a custom lockfile, set this option to a file path relative to the build root, then run ./pants generate-lockfiles --resolve=dockerfile-parser.

As explained at Third-party dependencies, lockfile generation via generate-lockfiles does not always work and you may want to manually generate the lockfile. You will want to set [python].invalid_lockfile_behavior = 'ignore' so that Pants does not complain about missing lockfile headers.
