// Package image provides end-to-end integration tests for runsc. These tests require
// docker and runsc to be installed on the machine. To set it up, run:
//
// ./runsc/test/install.sh [--runtime <name>]
//
// The tests expect the runtime name to be provided in the RUNSC_RUNTIME
// environment variable (default: runsc-test).
//
// Each test calls docker commands to start up a container, and tests that it is
// behaving properly, with various runsc commands. The container is killed and deleted
// at the end.
