Docker Helper

Convenience utilities for Python applications in Docker containers.

Functions

• Get current container ID

get_current_container_id()

Returns the ID of the container the application is currently running in, otherwise returns None if not running in a container.

This is done on a best-effort basis, guessed from the information in /proc/self/cgroup

• Read configuration values

read_configuration(key, path=None, default=None,
                   single_config=False, fallback_to_env=True)

A convenient way to read configuration values from files with an option to fall back to using environment variables. This can come handy to pass in multiple configuration options as key-value pairs using Docker configs or secrets when working with Swarm services. When single_config is True, the configuration file is treated as a single text value which is useful to read JSON configuration for example for an application.
