Testing and Deploying Your Application

Running locally

You run your application locally with the native development tools that you usually use.

Deploying your application

Deploy your app using the gcloud beta app deploy command. This command automatically builds a container image for you by using the Container Builder service before deploying the image to the App Engine flexible environment control plane. The container will include any local modifications you've made to the runtime image.

gcloud beta app deploy .\bin\Debug\netcoreapp1.0\publish\app.yaml

By default the deploy command automatically generates a new version ID each time that you use it and will route any traffic to the new version.

To override this behavior, you can specify the version ID with the version flag:

gcloud beta app deploy .\bin\Debug\netcoreapp1.0\publish\app.yaml --version myID

You can also specify not to send all traffic to the new version immediately with the --no-promote flag:

gcloud beta app deploy .\bin\Debug\netcoreapp1.0\publish\app.yaml --no-promote

Manually building a container for deployment

To build your container images outside of Google Cloud Platform, you must first upload your images to a container image repository before you can deploy your images to App Engine with the gcloud beta app deploy command.

For example, if you build your container images locally with Docker, you can push those images to Google Container Registry and then specify the URL of your image in the --image-url flag of the command:

gcloud beta app deploy .\bin\Debug\netcoreapp1.0\publish\app.yaml --image-url gcr.io/[MY_PROJECT_ID]/[MY_CONTAINER_IMAGE]

Docker base images for .NET

If you'd like to build a .NET custom runtime application from scratch, you can use this base image in a Dockerfile:

Runtime Docker command
.NET FROM gcr.io/google-appengine/aspnetcore:1.0.3

Viewing your application

After you deploy your app to App Engine, you can run the following command to launch your browser and view the app at http://[YOUR_PROJECT_ID].appspot.com:

gcloud app browse
