Fungsi Cloud Run Anda berjalan di lingkungan yang terdiri dari versi sistem operasi dengan paket add-on, dukungan bahasa, dan library Go Functions Framework yang mendukung dan memanggil fungsi Anda. Lingkungan ini diidentifikasi berdasarkan versi bahasa, dan dikenal sebagai ID runtime.
Persiapan fungsi
Anda dapat menyiapkan fungsi langsung dari konsol Google Cloud atau menulisnya di komputer lokal, lalu menguploadnya. Guna menyiapkan mesin lokal untuk pengembangan Go, lihat Menyiapkan lingkungan pengembangan Go.
Anda dapat memilih salah satu runtime Go yang didukung untuk fungsi Anda selama
deployment.
Anda dapat memilih versi runtime menggunakan konsol Google Cloud , atau gcloud CLI. Klik tab untuk mendapatkan petunjuk cara menggunakan alat pilihan Anda:
gcloud
Tentukan image dasar Go untuk fungsi Anda menggunakan flag --base-image,
saat men-deploy fungsi Anda. Contoh:
gcloud run deploy FUNCTION \
--source . \
--function FUNCTION_ENTRYPOINT \
--base-image go125
Ganti:
FUNCTION dengan nama fungsi yang Anda deploy. Anda dapat menghilangkan parameter ini sepenuhnya,
tetapi Anda akan diminta untuk memasukkan nama jika menghilangkannya.
FUNCTION_ENTRYPOINT dengan titik entri ke fungsi Anda dalam kode sumber. Ini adalah kode yang dieksekusi Cloud Run saat
fungsi Anda berjalan. Nilai flag ini harus berupa nama fungsi atau
nama class yang sepenuhnya memenuhi syarat yang ada dalam kode sumber Anda.
Untuk mendapatkan petunjuk mendetail tentang cara men-deploy fungsi menggunakan gcloud CLI, lihat Men-deploy fungsi di Cloud Run.
Konsol
Anda dapat memilih versi runtime saat membuat atau memperbarui fungsi Cloud Run di konsol Google Cloud . Untuk mengetahui petunjuk mendetail tentang cara men-deploy fungsi, lihat Men-deploy fungsi di Cloud Run.
Untuk memilih runtime di konsol Google Cloud saat Anda membuat fungsi, ikuti langkah-langkah berikut:
Klik Buat, dan tunggu hingga Cloud Run membuat layanan menggunakan revisi placeholder.
Konsol akan mengalihkan Anda ke tab Source tempat Anda dapat melihat kode sumber fungsi. Klik Simpan dan deploy ulang.
Untuk mengetahui petunjuk mendetail tentang cara memperbarui versi runtime setelah fungsi Anda di-deploy, lihat
Men-deploy ulang kode sumber baru.
Struktur kode sumber
Agar fungsi Cloud Run dapat menemukan definisi fungsi Anda, kode sumber Anda harus mengikuti struktur tertentu. Lihat artikel Menulis fungsi Cloud Run untuk mengetahui informasi selengkapnya.
Menentukan dependensi
Fungsi Cloud Run di Go harus menyediakan semua dependensinya dengan modul Go dan file go.mod, atau dengan direktori vendor. Untuk
informasi selengkapnya, lihat Menentukan dependensi di Go.
Variabel lingkungan
Runtime Go akan otomatis menetapkan variabel lingkungan tertentu untuk digunakan fungsi Anda sesuai kebutuhan. Untuk mengetahui detailnya, lihat Mengonfigurasi variabel lingkungan.
Jenis Context
Paket context Go menentukan jenis Context, yang memiliki batas waktu, sinyal pembatalan, dan nilai cakupan permintaan
lainnya di seluruh batas API dan antar-proses.

This environment is identified\nby the language version, and is known as the runtime ID.\n\nFunction preparation\n--------------------\n\nYou can prepare a function directly from the Google Cloud console or write it on\nyour local machine and upload it. To prepare your local machine for Go\ndevelopment, see [Set up a Go development environment](/go/docs/setup).\n\nSupported Go runtimes and base images\n-------------------------------------\n\n| **Note:** Go's [release policy](https://go.dev/doc/devel/release#policy) states that each major Go release is supported until there are two newer major releases. Thus, depending on when newer versions of Go are made publicly available, key dates such as end of support, deprecation, and decommission might be postponed.\n\nSelect your runtime\n-------------------\n\nYou can select one of the supported Go runtimes for your function during\ndeployment.\n\nYou can select a runtime version using the Google Cloud console, or the\ngcloud CLI. Click the tab for instructions on using the tool of\nyour choice: \n\n### gcloud\n\nSpecify the [Go base image](/run/docs/configuring/services/runtime-base-images#how_to_obtain_base_images) for your function using the `--base-image` flag,\nwhile deploying your function. For example: \n\n gcloud run deploy \u003cvar translate=\"no\"\u003eFUNCTION\u003c/var\u003e \\\n --source . \\\n --function \u003cvar translate=\"no\"\u003eFUNCTION_ENTRYPOINT\u003c/var\u003e \\\n --base-image go125\n\nReplace:\n\n- \u003cvar translate=\"no\"\u003eFUNCTION\u003c/var\u003e with the name of the function you are\n deploying. You can omit this parameter entirely,\n but you will be prompted for the name if you omit it.\n\n- \u003cvar translate=\"no\"\u003eFUNCTION_ENTRYPOINT\u003c/var\u003e with the entry point to your function in\n your source code. This is the code Cloud Run executes when your\n function runs. The value of this flag must be a function name or\n fully-qualified class name that exists in your source code.\n\nFor detailed instructions on deploying a function using the gcloud CLI, see [Deploy functions in Cloud Run](/run/docs/deploy-functions#gcloud).\n\n### Console\n\nYou can select a runtime version when you create or update a Cloud Run function in the Google Cloud console. For detailed\ninstructions on deploying a function, see [Deploy functions in Cloud Run](/run/docs/deploy-functions#deploy-functions).\n\nTo select a runtime in the Google Cloud console when you create a function, follow these steps:\n\n1. In the Google Cloud console, go to the Cloud Run page:\n\n [Go to Cloud Run](https://console.cloud.google.com/run)\n2. Click **Write a function**.\n\n3. In the **Runtime** list, select a Go runtime version.\n\n4. Click **Create**, and wait for Cloud Run to create the service\n using a placeholder revision.\n\n5. The console will redirect you to the **Source**\n tab where you can see the source code of your function. Click **Save and redeploy**.\n\nFor detailed instructions on updating the runtime version after your function is\ndeployed, see\n[Re-deploy new source code](/run/docs/deploy-functions#update-code-functions).\n\nSource code structure\n---------------------\n\nFor Cloud Run functions to find your function's definition, your\nsource code must follow a specific structure. See\n[Write Cloud Run functions](/run/docs/write-functions#go) for more\ninformation.\n\nSpecify dependencies\n--------------------\n\nCloud Run functions in Go must provide all of their dependencies\neither with Go modules and a `go.mod` file, or with a `vendor` directory. For\nmore information, see [Specify dependencies in Go](/run/docs/runtimes/go-dependencies).\n\nEnvironment variables\n---------------------\n\nYour Go runtime automatically sets certain environment variables for your function\nto use as needed. For details, see\n[Configure environment variables](/run/docs/configuring/services/environment-variables).\n\n`Context` type\n--------------\n\n[Go's `context` package](https://golang.org/pkg/context/) defines the `Context`\ntype, which carries deadlines, cancellation signals, and other request-scoped\nvalues across API boundaries and between processes.\n\nThe following code shows an example of context access by a\nPub/Sub client: \n\n\n // Package helloworld provides a set of Cloud Functions samples.\n package helloworld\n\n import (\n \t\"context\"\n \t\"fmt\"\n \t\"log\"\n\n \t\"github.com/GoogleCloudPlatform/functions-framework-go/functions\"\n \t\"github.com/cloudevents/sdk-go/v2/event\"\n )\n\n func init() {\n \tfunctions.CloudEvent(\"HelloPubSub\", helloPubSub)\n }\n\n // MessagePublishedData contains the full Pub/Sub message\n // See the documentation for more details:\n // https://cloud.google.com/eventarc/docs/cloudevents#pubsub\n type MessagePublishedData struct {\n \tMessage PubSubMessage\n }\n\n // PubSubMessage is the payload of a Pub/Sub event.\n // See the documentation for more details:\n // https://cloud.google.com/pubsub/docs/reference/rest/v1/PubsubMessage\n type PubSubMessage struct {\n \tData []byte `json:\"data\"`\n }\n\n // helloPubSub consumes a CloudEvent message and extracts the Pub/Sub message.\n func helloPubSub(ctx context.Context, e event.Event) error {\n \tvar msg MessagePublishedData\n \tif err := e.DataAs(&msg); err != nil {\n \t\treturn fmt.Errorf(\"event.DataAs: %w\", err)\n \t}\n\n \tname := string(msg.Message.Data) // Automatically decoded from base64.\n \tif name == \"\" {\n \t\tname = \"World\"\n \t}\n \tlog.Printf(\"Hello, %s!\", name)\n \treturn nil\n }"]]
