Executing commands

Container startup command

By default the container will execute whatever command is specified in the image's Dockerfile. To override this, and specify a different command, use withCommand. For example:

Specifying a startup command inside_block:startupCommand

Executing a command

Your test can execute a command inside a running container, similar to a docker exec call:

Executing a command inside a running container inside_block:standaloneExec

This can be useful for software that has a command line administration tool. You can also get the output (stdout/stderr) and exit code from the command - for example:

Executing a command inside a running container and reading the result inside_block:execReadingStdout

Environment variables

To add environment variables to the container, use withEnv:

java

new GenericContainer(...)
		.withEnv("API_TOKEN", "foo")
