Variables

You can create configuration variables on the user, organization and repository level. The level of the variable depends on where you created it. When creating a variable, the key will be converted to uppercase. You need use uppercase on the yaml file.

Naming conventions

The following rules apply to variable names:

• Variable names can only contain alphanumeric characters ([a-z], [A-Z], [0-9]) or underscores (_). Spaces are not allowed.
• Variable names must not start with the GITHUB_ and GITEA_ prefix.
• Variable names must not start with a number.
• Variable names are case-insensitive.
• Variable names must be unique at the level they are created at.
• Variable names must not start with CI.

Using variable

After creating configuration variables, they will be automatically filled in the vars context. They can be accessed through expressions like ${{ vars.VARIABLE_NAME }} in the workflow.

Precedence

If a variable with the same name exists at multiple levels, the variable at the lowest level takes precedence: A repository variable will always be chosen over an organization/user variable.
