如果您运行的是 AlloyDB Omni 操作器 1.0.0 版或更高版本,则后续步骤取决于您要升级到的 AlloyDB Omni 版本。AlloyDB Omni 版本号包含以下组成部分:
PostgreSQL 兼容性的主要版本号
PostgreSQL 兼容性的次要版本号
此 AlloyDB Omni 发布版本的补丁版本号
例如,AlloyDB Omni 15.7.0 版支持 PostgreSQL 15.7 版,并且没有 AlloyDB Omni 发布版本补丁。
选择适合您的目标版本的安装选项:
安装场景
更新步骤
您希望升级到支持较新版本 PostgreSQL 的 AlloyDB Omni 版本。
升级 AlloyDB Omni 操作器和数据库集群。每组支持特定 PostgreSQL 次要版本的 AlloyDB Omni 发布版本都有自己的 AlloyDB Omni 操作器版本号,您可以在 AlloyDB Omni 版本的版本说明中找到该版本号。使用 AlloyDB Omni 操作器版本兼容性表验证您的 AlloyDB Omni 操作器版本是否与您的操作器版本兼容。

The steps to upgrade AlloyDB Omni in Kubernetes depend on your current version of AlloyDB Omni and the version that you upgrade to.\n\n\u003cbr /\u003e\n\nDetermine your current versions\n-------------------------------\n\nTo check the version of AlloyDB Omni used by your database\ncluster, run the following command: \n\n kubectl get dbclusters.alloydbomni.dbadmin.goog \u003cvar translate=\"no\"\u003eDB_CLUSTER_NAME\u003c/var\u003e -n \u003cvar translate=\"no\"\u003eNAMESPACE\u003c/var\u003e -o jsonpath='{.status.primary.currentDatabaseVersion}'\n\nMake the following replacements:\n\n- \u003cvar translate=\"no\"\u003eDB_CLUSTER_NAME\u003c/var\u003e: the name of your database cluster. It's\n the same database cluster name that you declared when\n [you created it](/alloydb/omni/15.7.0/docs/deploy-kubernetes#create).\n\n- \u003cvar translate=\"no\"\u003eNAMESPACE\u003c/var\u003e: the Kubernetes namespace of your database\n cluster.\n\nIf you run version 1.0.0 or later of the AlloyDB Omni operator, then this\ncommand prints the version of AlloyDB Omni used by your database\ncluster.\n\nTo check the version of the AlloyDB Omni operator installed on your\nKubernetes cluster, run the following command: \n\n kubectl get dbclusters.alloydbomni.dbadmin.goog \u003cvar translate=\"no\"\u003eDB_CLUSTER_NAME\u003c/var\u003e -n \u003cvar translate=\"no\"\u003eNAMESPACE\u003c/var\u003e -o jsonpath='{.status.primary.currentControlPlaneAgentsVersion}'\n\nIf you run version 1.0.0 or later of the AlloyDB Omni operator, the\noutput is the version number of the AlloyDB Omni operator running on your\nKubernetes cluster.\n\nIf you run a version of AlloyDB Omni operator earlier than\n1.0.0, follow the instructions in\n[Upgrade from a pre-1.0.0 AlloyDB Omni operator](/alloydb/omni/15.7.0/docs/manage#older-operator).\nOtherwise, continue with\n[Check your target version numbers](#check-target-version).\n\nCheck your target version numbers\n---------------------------------\n\nIf you run a version of AlloyDB Omni operator 1.0.0 or later, then\nyour next steps depend on the version of AlloyDB Omni that\nyou want to upgrade to. The AlloyDB Omni version number has\nthe following components:\n\n- The major version number of its PostgreSQL compatibility\n- The minor version number of its PostgreSQL compatibility\n- The patch version number of this AlloyDB Omni release\n\nFor example, AlloyDB Omni version 15.7.0\nsupports PostgreSQL version 15.7 and doesn't have a AlloyDB Omni\nrelease patch.\n\nChoose the installation option that works for your target version:\n\nUpgrade the AlloyDB Omni operator\n---------------------------------\n\nTo upgrade the AlloyDB Omni operator, follow these steps:\n\n1. Define the environment variables:\n\n export GCS_BUCKET=alloydb-omni-operator\n export OPERATOR_VERSION=\u003cvar translate=\"no\"\u003eOPERATOR_VERSION\u003c/var\u003e\n export HELM_PATH=$OPERATOR_VERSION/alloydbomni-operator-$OPERATOR_VERSION.tgz\n\n Replace \u003cvar translate=\"no\"\u003eOPERATOR_VERSION\u003c/var\u003e with the version of the\n AlloyDB Omni operator that you're upgrading to---for example,\n `1.3.0`.\n2. Download the latest AlloyDB Omni operator:\n\n gcloud storage cp -r gs://$GCS_BUCKET/$HELM_PATH ./\n tar -xvzf alloydbomni-operator-${OPERATOR_VERSION}.tgz\n\n3. Apply the latest AlloyDB Omni operator custom resource definitions:\n\n kubectl apply -f alloydbomni-operator/crds\n\n4. Upgrade the AlloyDB Omni operator Helm chart:\n\n helm upgrade alloydbomni-operator alloydbomni-operator-${OPERATOR_VERSION}.tgz \\\n --namespace alloydb-omni-system \\\n --atomic \\\n --timeout 5m\n\n To update the `dbCluster`, you need to update the `databaseVersion` and the\n `controlPlaneAgentsVersion` versions in the manifest file. The following is\n part of a manifest file that specifies version 15.7.0\n of `databaseVersion` and version 1.3.0 of\n `controlPlaneAgentsVersion`: \n\n ```html\n apiVersion: alloydbomni.dbadmin.goog/v1\n kind: DBCluster\n metadata:\n name: DB_CLUSTER_NAME\n spec:\n databaseVersion: \"15.7.0\"\n controlPlaneAgentsVersion: \"1.3.0\"\n ...\n ```\n | **Note:** When you upgrade the AlloyDB Omni operator, the database restarts unless all of the following are true:\n | - You're upgrading the AlloyDB Omni operator version 1.1.1 to a newer version.\n | - You're using the AlloyDB Omni database version 15.5.5 or later.\n | - AlloyDB AI is not [enabled](/alloydb/omni/15.7.0/docs/install-with-alloydb-ai?resource=kubernetes#enable-alloydb-ai).\n | If the database restarts, no data loss is expected."]]
