This sample YML file shows two task types you can run:

• Shell: a task launching a shell command
• Docker: a task optimized for docker containers
• Group: a task that groups other tasks (for parallel execution)

The task runner supports searching for a pattern in the task output to signal its completion. This way you can start a dependent task after the pattern shows up in the task output.

Tasks are chained through dependencies. If you declare a task dependency on another task, it will wait for the first task to complete before launching the second task
