服务名称在 Google Cloud App Engine 标准 spring 启动 java 11 maven 部署中没有改变

Question

I'm trying to deploy to google cloud App Engine standard, a spring boot java 11 maven microservice using app.yml. It deploys but it deploys with default as service name. I want to deploy it with a custom name.

I tried to put the tag service in the app.yml file but it stills has the same name.

Here is my app.yml file

runtime: java11
instance_class: F1
env: standard
service: mycustomname
entrypoint: java -noverify -jar helloworld.jar

and here is my pom

I'm deploying using this command gcloud app deploy target/helloworld.jar

In App Engine there must be always a default service no matter what.

According to your app.yaml file, your attempting to deploy a service called mycustomname and this will create a new service called like that but you will not be able to rename the service default since this is not possible.

You will see the new service going to the Cloud Console -> App Engine -> Versions. Once there, there is a drop down menu to choose the other services.
