This page documents the variable substitutions supported by Tasks and Pipelines.
For instructions on using variable substitutions see the relevant section of the Tasks doc.
Note: Tekton does not escape the contents of variables. Task authors are responsible for properly escaping a variable's value according to the shell, image or scripting language that the variable will be used in.
