Variable Substitutions Supported by Tasks and Pipelines
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.
