AppEngine Deploy Error (app.yaml)

Question

I am trying to deploy the app.yaml file to appengine flexible.

Here is my app.yaml file

runtime: java
env: flex
manual_scaling:
  instances: 1

handlers:
- url: /.*
  script: this field is required, but ignored
  secure: always

runtime_config:  # Optional
  jdk: openjdk8
  server: jetty9

resources:
  cpu: 0.5
  memory_gb: 0.18
  disk_size_gb: 10

I am trying to deploy it with this command:

gcloud app deploy app.yaml --verbosity=debug

And this is the error I get:

DEBUG: No staging command found for runtime [java] and environment [FLEX].

So it ends up not deploying the app.yaml. However, if I run this command:

gcloud app deploy cron.yaml

It will work just fine.

Answer 1

Yeah, this is a gap right now :/ You can't actually deploy a Java app to App Engine flexible via gcloud app deploy. You need to use the Maven or Gradle plugins.

Sorry for the trouble!
