Why can't I change the settings of the App Runner service?

日本語版はこちら

The issue

I paused the service to change the settings of the App Runner service on the console, but the "Edit" button has become unclickable.

Is it not possible to change the settings of the App Runner service?

The solution

In the App Runner service, it is designed so that no changes can be made while the service is paused, except for tagging changes.

AWS official documentation

Actions you cannot perform on a paused service

• StartDeployment actions (or a manual deployment using the console)
• UpdateService (or a configuration change using the console, except for tagging changes)
• CreateCustomDomainAssociations, DeleteCustomDomainAssociations
• CreateConnection, DeleteConnection

Therefore, when making changes to the settings of the App Runner service, please change the service status to Running.

I tried it

I created an App Runner service and set its status to Paused.

In this state, even if I try to change the settings, the "Edit" button is inactive and I cannot make any changes.

I will change the status to Running and try to modify the settings again.

This time, I will change the memory from 2GB to 3GB.

This time, I was able to change the settings.

After changing the settings, a message indicating that the settings are being updated is displayed.

After the update is complete, I can confirm that the memory value has been changed to 3GB.
