개발 단계에서는 배포하기 전에 로컬에서 컨테이너 이미지를 실행하고 테스트할 수 있습니다. Cloud Code 또는 로컬에서 설치된 Docker를 사용하여 Google Cloud 서비스에 대한 액세스 권한으로 로컬 실행을 포함하여 로컬에서 실행하고 테스트할 수 있습니다.
Knative serving 에뮬레이터에서 실행
VS Code 및 JetBrains IDE용 Cloud Code 플러그인을 사용하면 IDE 내 Knative serving 에뮬레이터에서 로컬에서 컨테이너 이미지를 실행하고 디버깅할 수 있습니다. 에뮬레이터를 사용하면 Knative serving에서 실행 중인 서비스를 대표하는 환경을 구성할 수 있습니다.
CPU 및 메모리 할당과 같은 속성을 구성하고 환경 변수를 지정하고 Cloud SQL 데이터베이스 연결을 설정할 수 있습니다.
컨테이너를 처음 사용하는 경우 Docker 시작하기 가이드를 먼저 검토하는 것이 좋습니다. Docker 명령어에 대한 자세한 내용은 Docker 문서를 참조하세요.
Google Cloud 서비스에 대한 액세스 권한으로 Docker를 사용해 로컬에서 실행
Google Cloud 클라이언트 라이브러리를 사용하여 Google Cloud 서비스와 애플리케이션을 통합했지만 외부 액세스를 제어하도록 서비스를 아직 보호하지 않은 경우 서비스 계정 키를 사용해서 Google Cloud서비스에 인증하도록 로컬 컨테이너를 설정할 수 있습니다.

You can use [Cloud Code](/code) or\n[Docker installed locally](https://docs.docker.com/install/) to run and test\nlocally, including running locally with access to Google Cloud services.\n\nRunning in a Knative serving emulator\n-------------------------------------\n\nThe [Cloud Code](https://cloud.google.com/code) plugin for\n[VS Code](https://code.visualstudio.com/) and [JetBrains IDEs](https://www.jetbrains.com/)\nlets you locally run and debug your container image in a Knative serving\nemulator within your IDE. The emulator allows you configure an environment that is\nrepresentative of your service running on Knative serving.\n\nYou can configure properties like CPU and memory allocation,\nspecify environment variables, and set Cloud SQL\ndatabase connections.\n\n1. Install Cloud Code for [VS Code](/code/docs/vscode/install) or a [JetBrains IDE](/code/docs/intellij/install).\n2. Follow the instructions for locally developing and debugging within your IDE.\n - **VS Code** : Locally [developing](/code/docs/vscode/developing-a-cloud-run-app) and [debugging](/code/docs/vscode/debugging-a-cloud-run-app)\n - **IntelliJ** : Locally [developing](/code/docs/intellij/developing-a-cloud-run-app) and [debugging](/code/docs/intellij/debugging-a-cloud-run-app)\n\nRunning locally using Docker\n----------------------------\n\nTo test your container image locally using Docker:\n\n1. Use the Docker command:\n\n ```bash\n PORT=8080 && docker run -p 9090:${PORT} -e PORT=${PORT} IMAGE_URL\n ```\n\n Replace \u003cvar translate=\"no\"\u003eIMAGE_URL\u003c/var\u003e with a reference to the container image, for\n example, `gcr.io/cloudrun/hello`.\n\n The `PORT` environment variable specifies the port your application will\n use to listen for HTTP or HTTPS requests. This is a requirement from\n the [Container Runtime Contract](/kubernetes-engine/enterprise/knative-serving/docs/reference/container-contract).\n In this example, we use port 8080.\n2. Open \u003chttp://localhost:9090\u003e in your browser.\n\nIf you are new to working with containers, you may want to review the\n[Docker Getting Started](https://docs.docker.com/get-started/) guide. To learn\nmore about Docker commands, refer to the\n[Docker documentation](https://docs.docker.com/engine/reference/run/).\n\nRunning locally using Docker with access to Google Cloud services\n-----------------------------------------------------------------\n\nIf you are using Google Cloud client libraries to integrate your application\nwith Google Cloud services, and have not yet secured those services to control external\naccess, you can set up your local container to authenticate with Google Cloud\nservices using a service account key.\n| **Note:** Service account keys are a security risk if not managed correctly. You should [choose a more secure alternative to service account keys](/docs/authentication#auth-decision-tree) whenever possible. If you must authenticate with a service account key, you are responsible for the security of the private key and for other operations described by [Best practices for managing service account keys](/iam/docs/best-practices-for-managing-service-account-keys). If you are prevented from creating a service account key, service account key creation might be disabled for your organization. For more information, see [Managing secure-by-default organization resources](/resource-manager/docs/secure-by-default-organizations).\n|\n|\n| If you acquired the service account key from an external source, you must validate it before use.\n| For more information, see [Security requirements for externally sourced credentials](/docs/authentication/external/externally-sourced-credentials).\n\nTo run locally:\n\n1. Refer to [Service account key](/docs/authentication/set-up-adc-on-premises#wlif-key)\n for help with setting up your credentials.\n\n2. The following Docker run flags inject the credentials and configuration from\n your local system into the local container:\n\n 1. Use the `--volume` (`-v`) flag to inject the credential file into the container (assumes you have already set your `GOOGLE_APPLICATION_CREDENTIALS` environment variable on your machine): \n\n ```bash\n -v $GOOGLE_APPLICATION_CREDENTIALS:/tmp/keys/FILE_NAME.json:ro\n ```\n 2. Use the `--environment` (`-e`) flag to set the `GOOGLE_APPLICATION_CREDENTIALS` variable inside the container: \n\n ```bash\n -e GOOGLE_APPLICATION_CREDENTIALS=/tmp/keys/FILE_NAME.json\n ```\n3. Optionally, use this fully configured Docker `run` command:\n\n ```bash\n PORT=8080 && docker run \\\n -p 9090:${PORT} \\\n -e PORT=${PORT} \\\n -e K_SERVICE=dev \\\n -e K_CONFIGURATION=dev \\\n -e K_REVISION=dev-00001 \\\n -e GOOGLE_APPLICATION_CREDENTIALS=/tmp/keys/FILE_NAME.json \\\n -v $GOOGLE_APPLICATION_CREDENTIALS:/tmp/keys/FILE_NAME.json:ro \\\n IMAGE_URL\n ```\n\n Note that the path \n\n ```\n /tmp/keys/FILE_NAME.json\n ```\n shown in the example above is a reasonable location to place your credentials inside the container.\n\n \u003cbr /\u003e\n\n However, other directory locations will also work. The crucial requirement\n is that the `GOOGLE_APPLICATION_CREDENTIALS` environment variable must\n match the bind mount location inside the container.\n\n Note also, that with some Google Cloud services, you may want to use an alternate\n configuration to isolate local troubleshooting from production performance\n and data.\n\nWhat's next\n-----------\n\nTo learn how to deploy your built containers, follow [Deploying Services](/kubernetes-engine/enterprise/knative-serving/docs/deploying)."]]
