// Package image provides end-to-end image 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, like connecting to a port or looking at the output. The
|
|
// container is killed and deleted at the end.
