No code changes are required.\n\nBefore you begin\n\nBefore following the instructions on this page, take the following steps:\n\n1. Verify that your app deploys and runs successfully in the App Engine flexible environment.\n\n2. In these instructions, you'll use the same project that you used for your\n App Engine app. You can always create and use a new project, if you want.\n\n3.\n\n\n Enable the GKE, Cloud Build APIs.\n\n\n [Enable the APIs](https://console.cloud.google.com/flows/enableapi?apiid=container.googleapis.com,cloudbuild.googleapis.com&redirect=https://console.cloud.google.com)\n\n \u003cbr /\u003e\n\n4. Download and install the Google Cloud CLI and then initialize the gcloud tool:\n [Download the Google Cloud SDK](/sdk/docs).\n\n Alternatively, you can use\n [Cloud Shell](/shell/docs/launching-cloud-shell), which comes with the\n gcloud CLI, `git`, and other pre-installed\n [features](/shell/docs/how-cloud-shell-works#tools), such as language\n support, tools, and editors.\n5. Install the `kubectl` command-line tool:\n\n gcloud components install kubectl\n\n6. [Download and install git](https://git-scm.com/).\n\nCreating a Dockerfile for your App Engine app\n\nBuild a Dockerfile for your app as described in\n[Create a Dockerfile](/appengine/docs/flexible/custom-runtimes/build#docker).\n\nBuilding a container from the Dockerfile\n\nTo build a container:\n\n1. Ensure you are in the App Engine app directory that contains the Dockerfile.\n\n2. Change the default project used by the `gcloud` tool so it points to the project you are using to run your app in GKE:\n\n gcloud config set project [YOUR-PROJECT-ID]\n\n Replace `[YOUR-PROJECT-ID]` with your GKE project ID.\n3. Build the container using the following command:\n\n gcloud builds submit --tag gcr.io/[YOUR-PROJECT-ID]/[YOUR-CONTAINER-NAME] .\n\n Replace `[YOUR-PROJECT-ID]` with the project ID of your GKE project, and replace `[YOUR-CONTAINER-NAME]` with the name of the container you want to use for your app container.\n4. Wait for the container to build: it may take awhile. When it finishes successfully, it shows a message like this one:\n\n Created [https://cloudbuild.googleapis.com/v1/projects/YOUR-PROJECT-ID/builds/xxxxxxx-xxxx-xxx-xxx-xxxxxxxxxxxx].\n Logs are permanently available at [https://console.developers.google.com/logs/viewer?resource=build&project=YOUR-PROJECT-ID&filters=text:xxxx-xxx-xxx-xxxxxxxxxxxx]].\n\n ID CREATE_TIME DURATION SOURCE IMAGES STATUS\n xxxxxxx-xxxx-xxx-xxx-xxxxxxxxxxxx 2017-03-04T00:42:10+00:00 1M32S gs://YOUR-PROJECT-ID_cloudbuild/source/xxxxxxx.08.tgz gcr.io/YOUR-PROJECT-ID/YOUR-CONTAINER-NAME SUCCESS\u003c\n\n Note the container name: you need to specify this when you run it in GKE.\n\nRunning your app in GKE\n\nTo run the container that holds your app:\n\n1. Create the cluster (this may take a few minutes):\n\n gcloud container clusters create [YOUR-CLUSTER-NAME]\n\n Replace `[YOUR-CLUSTER-NAME]` with the name you want to give the cluster.\n2. From the command line, set your compute zone:\n\n gcloud config set compute/zone us-central1-b\n\n3. Make sure the GKE `kubectl` tool is authorized:\n\n gcloud container clusters get-credentials [YOUR-CLUSTER-NAME]\n\n Follow the prompts to authorize the tool.\n4. Run the container that holds your app:\n\n kubectl create deployment [YOUR-DEPLOYMENT-NAME] --image=gcr.io/[YOUR-PROJECT-ID]/[YOUR-CONTAINER-NAME]\n\n Replace `[YOUR-DEPLOYMENT-NAME]` with the name you want to use for your\n deployment, replace `[YOUR-PROJECT-ID]` with your GKE project\n ID, and replace `[YOUR-CONTAINER-NAME]` with the name of the container you\n created for your app.\n5. Expose the container for public access:\n\n kubectl expose deployment [YOUR-DEPLOYMENT-NAME] --type=\"LoadBalancer\" --port=8080\n\n Replace `[YOUR-DEPLOYMENT-NAME]` with the name you used in the previous steps. You\n may need to wait several minutes before the external IP is viewable.\n | **Note:** The **type=\"LoadBalancer\"** option in `kubectl` requests that Google Cloud Platform provision a load balancer for your container, which is billed per the regular Load Balancer pricing.\n6. View the external IP address for your app:\n\n kubectl get service [YOUR-DEPLOYMENT-NAME]\n\n Replace `[YOUR-DEPLOYMENT-NAME]` with the name you used in the previous\n steps. If the `EXTERNAL IP` field is empty, wait for awhile, then re-invoke the\n command.\n7. View the app running in GKE:\n\n http://EXTERNAL-IP:8080\n\n Replace `EXTERNAL-IP` with the external IP address you obtained in the\n previous step.\n\nYou've successfully deployed and run your App Engine app on GKE!\n\nWhat's next\n\nYou may want to learn more about Kubernetes and the `kubectl` command.\nGoogle Kubernetes Engine uses Kubernetes for container management, deployment and\nscaling. More information on Kubernetes is available on the external\n[Kubernetes site](http://kubernetes.io/).\n\nThis guide uses `kubectl`, the command line interface for managing\nKubernetes clusters. More information on `kubectl` is available in the\n[kubectl reference](https://kubernetes.io/docs/reference/kubectl/)."]]
