Steps
Learn about steps pipelines.
A steps pipeline is designed to run a sequential set of tasks.
These pipelines do not have a minimum defined length and steps will always execute in the order defined.
In this pipeline each step is shown with the minimum required YAML tags to execute a step.
Both steps are pulling a Alpine Linux image from Docker Hub and executing echo statements.

version: "1"
# In this pipeline, commands are executed inside the container as the Entrypoint.
# If any command returns a non-zero exit code, the pipeline fails and exits.
