Managing Aliases¶
Overview¶
An alias points to a specific function version. Create an alias and expose it to clients, for example, bind a trigger to the alias instead of the corresponding version. Then your modification to the version for update or rollback will be imperceptible to the clients. An alias can point to up to two versions with different weights for dark launch.
Creating an Alias¶
Log in to the FunctionGraph console. In the navigation pane, choose Functions > Function List.
Click the function to be configured to go to the function details page.
On the Aliases tab page, click Create Alias.
