Module Contents

class deps_rocker.dependencies.Dependencies

Bases: rocker.extensions.RockerExtension

The base class for Rocker extension points

name = 'deps'

deps_files = []

dependencies

layers_preamble

layers

layers_user

dep_group_order

empy_args

all_files

parsed = False

classmethod get_name()

invoke_after(cliargs) → Set[str]: This extension should be loaded after the extensions in the returned set. These extensions are not required to be present, but if they are, they will be loaded before this extension.

setup_deps(cliargs)

read_dependencies(path: pathlib.Path, pattern: str): Recursively load all deps.yaml and create a dictionary containing sets of each type of dependency. Each type of dependency (apt_base, apt etc) should have duplicates rejected when adding to the set

get_deps(key: str, as_list: bool = False) → str

Given a dependency key return a space delimited string of dependencies

Parameters:: key (str) – A type of dependency e.g apt
Returns:: space delimited dependencies
Return type:: str

get_files(cliargs) → dict: Get a dict of local filenames and content to write into them

add_file(filename: str, content: str) → None

Create a file on the users host machine to be copied into the docker context. This also updates the empy_args dictionary with True if that file is generated. The empy_args are used to determine if a snipped related to that file should be generated or not.

Parameters:

filename (str) – name of file to create
content (str) – the contents of the file

get_scripts(name: str) → str

collect all scripts files into a single script

Parameters:: name (str) – name of the scripts key and output script name
Returns:: All scripts combined into a single script
Return type:: str

get_pyproject_toml_deps() → str

Recursively load all dependencies from pyproject.toml”

Returns:: Space delimited string of dependencies
Return type:: str

get_preamble(cliargs)

get_snippet(cliargs=None): Get a dockerfile snippet to be executed as ROOT.

get_user_snippet(cliargs): Get a dockerfile snippet to be executed after switching to the expected USER.
