Les variables d'environnement de compilation sont des paires clé/valeur qui vous permettent de transmettre des informations de configuration aux packs de création lors du déploiement d'une fonction à partir du code source. Par exemple, au moment de la compilation, vous pouvez personnaliser les options du compilateur, spécifier des certificats au moment de la compilation, configurer des paramètres, etc.
Cette page explique comment définir des variables d'environnement de compilation disponibles au moment de la compilation. Elle s'adresse aux développeurs de plate-forme qui déploient des fonctions dans Cloud Run.
Avant de commencer
Activez l'API Cloud Build :
gcloudservicesenablecloudbuild.googleapis.com
Rôles requis
Pour obtenir les autorisations nécessaires pour déployer à partir de la source, demandez à votre administrateur de vous accorder les rôles IAM suivants sur votre projet :
Définir des variables d'environnement de compilation
Vous pouvez définir des variables d'environnement de compilation pour établir de nouvelles variables ou remplacer complètement des variables de compilation existantes.
gcloud
Vous pouvez définir des variables d'environnement de compilation lorsque vous déployez une fonction à partir du code source :
FUNCTION_ENTRY_POINT par le point d'entrée de votre fonction dans votre code source ;
KEY1=VALUE1,KEY2=VALUE2 par la liste de noms de variables séparés par une virgule et de leurs valeurs, déployées avec une fonction qui vous permet de transmettre des informations de configuration aux buildpacks.
Mettre à jour des variables d'environnement de compilation
Vous pouvez mettre à jour les variables d'environnement de compilation pour les fonctions existantes.
Il s'agit d'une approche non destructrice, qui permet de modifier ou d'ajouter des variables d'environnement de compilation sans les supprimer.
gcloud
Pour mettre à jour une variable d'environnement de compilation pour des fonctions existantes :
Remplacez FILE_NAME.yaml par le contenu du fichier qui ressemble à ceci :
KEY1: VALUE1
KEY2: VALUE2

For example, at build time, you might want to customize\ncompiler options, specify build-time certificates, configure parameters, and so\nforth.\n\nThis page shows how to set build environment variables that are available at\nbuild time, and is relevant for platform developers who are deploying\nCloud Run [services](/run/docs/deploying-source-code) or\n[functions](/run/docs/deploy-functions) from source. The build environment\nvariable gcloud CLI flags are supported for\n[source deployments](/run/docs/deploying-source-code) (`--source`), and not\nsupported for [container image deployments](/run/docs/deploying) (`--image`).\n\nYou can use environment variables for service or function configuration, but we don't\nrecommend them as a way to store secrets such as database credentials or API keys.\nStore sensitive values outside both your source code and environment variables. To\nstore secrets, we recommend using Secret Manager.\nTo configure services that access secrets stored in Secret Manager,\nsee [Configure secrets](/run/docs/configuring/secrets).\n\nBefore you begin\n----------------\n\n- Enable the Cloud Run Admin API and the Cloud Build API:\n\n ```bash\n gcloud services enable run.googleapis.com \\\n cloudbuild.googleapis.com\n ```\n\n After the Cloud Run Admin API is enabled, the Compute Engine default service account is\n automatically created.\n\n### Required roles\n\nYou or your administrator must grant the deployer account and the\nCloud Build service account the following IAM roles. \n\n#### Click to view required roles for the deployer account\n\nTo get the permissions that you need to build and deploy from source,\nask your administrator to grant you the following IAM\nroles:\n\n- [Cloud Run Source Developer](/iam/docs/understanding-roles#run.sourceDeveloper) (`roles/run.sourceDeveloper`) on your project\n- [Service Usage Consumer](/iam/docs/understanding-roles#serviceusage.serviceUsageConsumer) (`roles/serviceusage.serviceUsageConsumer`) on your project\n- [Service Account User](/iam/docs/understanding-roles#iam.serviceAccountUser) (`roles/iam.serviceAccountUser`) on the Cloud Run service identity \n\n#### Click to view required roles for the Cloud Build service account\n\nCloud Build automatically uses the\n[Compute Engine default service\naccount](/build/docs/cloud-build-service-account) as the default Cloud Build service account to build your source code and\nCloud Run resource, unless you override this behavior. For\nCloud Build to build your sources, ask your administrator to grant\n[Cloud Run Builder](/iam/docs/understanding-roles#run.builder)\n(`roles/run.builder`) to the Compute Engine default\nservice account on your project: \n\n```bash\n gcloud projects add-iam-policy-binding PROJECT_ID \\\n --member=serviceAccount:PROJECT_NUMBER-compute@developer.gserviceaccount.com \\\n --role=roles/run.builder\n \n```\n\nReplace \u003cvar translate=\"no\"\u003ePROJECT_NUMBER\u003c/var\u003e with your Google Cloud\nproject number, and \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with your Google Cloud\nproject ID. For detailed instructions on how to find your project ID, and project number,\nsee [Creating\nand managing projects](/resource-manager/docs/creating-managing-projects#identifying_projects).\n\nGranting the Cloud Run builder role to the Compute Engine default service account\ntakes a couple of minutes to [propagate](/iam/docs/access-change-propagation).\n| **Note:**\n|\n|\n| The [`iam.automaticIamGrantsForDefaultServiceAccounts` organization policy constraint](/resource-manager/docs/organization-policy/restricting-service-accounts#disable_service_account_default_grants)\n| prevents the Editor role from being automatically granted to default service accounts. If you\n| created your organization after May 3, 2024, this constraint is enforced by\n| default.\n|\n|\n| We strongly recommend that you enforce this constraint to disable the automatic role grant. If you\n| disable the automatic role grant, you must decide which roles to grant to the default service\n| accounts, and then [grant these roles](/iam/docs/granting-changing-revoking-access)\n| yourself.\n|\n|\n| If the default service account already has the Editor role, we recommend that you replace the\n| Editor role with less permissive roles.To safely modify the service account's roles, use [Policy Simulator](/policy-intelligence/docs/simulate-iam-policies) to see the impact of\n| the change, and then [grant and revoke the\n| appropriate roles](/iam/docs/granting-changing-revoking-access).\n\nFor a list of IAM roles and permissions that are associated with\nCloud Run, see\n[Cloud Run IAM roles](/run/docs/reference/iam/roles)\nand [Cloud Run IAM permissions](/run/docs/reference/iam/permissions).\nIf your Cloud Run service interfaces with\nGoogle Cloud APIs, such as Cloud Client Libraries, see the\n[service identity configuration guide](/run/docs/configuring/services/service-identity).\nFor more information about granting roles, see\n[deployment permissions](/run/docs/reference/iam/roles#additional-configuration)\nand [manage access](/iam/docs/granting-changing-revoking-access).\n\nMaximum number of build environment variables and limits\n--------------------------------------------------------\n\nYou can define up to 100 build environment\nvariables, with a total key and value limit of 64 KiB.\n\nSet build environment variables\n-------------------------------\n\nYou can set build environment variables to establish new variables or completely\nreplace existing build variables.\n**Note:** Keys must start with an uppercase ASCII letter, and consist of uppercase ASCII letters, digits, and underscores. You should avoid creating variable keys with a `GOOGLE_*` prefix. [View all supported buildpacks environment variables](/docs/buildpacks/service-specific-configs). \n\n### gcloud\n\nTo set build environment variables when deploying a service from\nsource code, use the `--set-build-env-vars` flag: \n\n```bash\ngcloud run deploy SERVICE \\\n --source . \\\n --set-build-env-vars KEY1=VALUE1,KEY2=VALUE2\n```\n\nReplace:\n\n- \u003cvar translate=\"no\"\u003eSERVICE\u003c/var\u003e with name of your Cloud Run service.\n- \u003cvar translate=\"no\"\u003eKEY1=VALUE1,KEY2=VALUE2\u003c/var\u003e with the comma-separated list of variable names and their values that are deployed alongside a function that let you pass configuration information to buildpacks.\n\nIf you are deploying a function, add the `--function` flag with the function\nentry point from your source code.\n\nUpdate build environment variables\n----------------------------------\n\nYou can update build environment variables for existing services. This is a\nnon-destructive approach that changes or adds build environment variables, but\ndoes not delete the build environment variables. \n\n### gcloud\n\nTo update build environment variables for existing services, use the\n`--update-build-env-vars` flag: \n\n```bash\ngcloud run deploy SERVICE \\\n --source . \\\n --update-build-env-vars KEY1=VALUE1,KEY2=VALUE2\n```\n\nIf you are deploying a function, add the `--function` flag with the function\nentry point from your source code.\n\nDelete build environment variables\n----------------------------------\n\nYou can delete build environment variables for existing services. \n\n### gcloud\n\nTo remove build environment variables for existing services, use the\n`--remove-build-env-vars` flag: \n\n```bash\ngcloud run deploy SERVICE \\\n --source . \\\n --remove-build-env-vars KEY1=VALUE1,KEY2=VALUE2\n```\n\nAlternatively, you can clear build environment variables by using the\n`--clear-build-env-vars` for existing services: \n\n```bash\ngcloud run deploy SERVICE \\\n --source . \\\n --clear-build-env-vars KEY1=VALUE1,KEY2=VALUE2\n```\n\nIf you are deploying a function, add the `--function` flag with the function\nentry point from your source code.\n\nUse a build environment variables file\n--------------------------------------\n\nYou can use a build environment variables file for existing functions. \n\n### gcloud\n\nTo set build environment variables from a file, use the\n`--build-env-vars-file` flag: \n\n```bash\ngcloud run deploy SERVICE \\\n --source . \\\n --build-env-vars-file FILE_NAME.yaml\n```\n\nReplace \u003cvar translate=\"no\"\u003eFILE_NAME\u003c/var\u003e.yaml where the contents of the file, which\nshould look as follows: \n\n KEY1: VALUE1\n KEY2: VALUE2\n\nIf you are deploying a function, add the `--function` flag with the function\nentry point from your source code."]]
