## 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 be `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.
