galaxy.tool_util.deps.container_resolvers package

The module defines the abstract interface for resolving container images for tool execution.

class galaxy.tool_util.deps.container_resolvers.ResolutionCache(**kwds)

Bases: Bunch

Simple cache for duplicated computation created once per set of requests (likely web request in Galaxy context).

This should not be assumed to be thread safe - resolution using a given cache should all occur one resolution at a time in a single thread.

mulled_resolution_cache: Optional[Cache] = None

class galaxy.tool_util.deps.container_resolvers.ContainerResolver(app_info: Optional[AppInfo] = None, **kwds)

Bases: Dictifiable

Description of a technique for resolving container images for tool execution.

dict_collection_visible_keys = ['resolver_type', 'can_uninstall_dependencies', 'builds_on_resolution']

can_uninstall_dependencies = False

builds_on_resolution = False

read_only = True

__init__(app_info: Optional[AppInfo] = None, **kwds) → None

Default initializer for ContainerResolver subclasses.

abstract resolve(enabled_container_types, tool_info, resolution_cache=None, **kwds)

Find a container matching all supplied requirements for tool.

The supplied argument is a galaxy.tool_util.deps.containers.ToolInfo description of the tool and its requirements.

abstract property resolver_type

Short label for the type of container resolution.

Submodules

galaxy.tool_util.deps.container_resolvers.explicit module

This module describes the ExplicitContainerResolver ContainerResolver plugin.

class galaxy.tool_util.deps.container_resolvers.explicit.ExplicitContainerResolver(app_info: Optional[AppInfo] = None, **kwds)

Bases: ContainerResolver

Find explicit containers referenced in the tool description (e.g. tool XML file) if present.

resolver_type = 'explicit'

resolve(enabled_container_types, tool_info, **kwds)

Find a container explicitly mentioned in tool description.

This ignores the tool requirements and assumes the tool author crafted a correct container.

class galaxy.tool_util.deps.container_resolvers.explicit.ExplicitSingularityContainerResolver(app_info: Optional[AppInfo] = None, **kwds)

Bases: ExplicitContainerResolver

resolver_type = 'explicit_singularity'

container_type = 'singularity'

resolve(enabled_container_types, tool_info, **kwds)

Find a container explicitly mentioned in tool description.

This ignores the tool requirements and assumes the tool author crafted a correct container. We use singularity here to fetch docker containers, hence the container_description hack here.

class galaxy.tool_util.deps.container_resolvers.explicit.CachedExplicitSingularityContainerResolver(*args, **kwargs)

Bases: CliContainerResolver

resolver_type = 'cached_explicit_singularity'

container_type = 'singularity'

cli = 'singularity'

__init__(*args, **kwargs)

Default initializer for ContainerResolver subclasses.

resolve(enabled_container_types, tool_info, install=False, **kwds)

Find a container explicitly mentioned in tool description.

This ignores the tool requirements and assumes the tool author crafted a correct container. We use singularity here to fetch docker containers, hence the container_description hack here.

__init__(app_info=None, identifier='', **kwds)

Default initializer for ContainerResolver subclasses.
