[Github Action Workflow Example] #github #git #actions #workflows

1. Github Action Workflow Example.md

See https://github.com/Integralist/actions-testing for working examples.

DOCS: Syntax and Expressions.

The following example demonstrates a few things...

1. Events using on.
2. Generating multiple jobs using strategy.matrix.
3. Overriding specific variables using include.
4. Setting environment variables using env.
5. Defining a multiline script (for readability) using yaml | operator.
