Updating a trigger in Serverless Containers
You can update any parameters except for the trigger type and launched resource type.
Note

- In the management console
, select the folder containing your trigger. - Open Serverless Containers.
- In the left-hand panel, select
Triggers. - Select the trigger whose parameters you want to update.
- In the top-right corner of the page, click Edit.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.
By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID>
command. You can also set a different folder for any specific command using the --folder-name
or --folder-id
parameter.
To find out the name or unique ID of a trigger, get a list of triggers in the folder.
