安装和使用 MongoDB Community Edition

您可以使用Kubernetes Operator 并部署mongot进程资源,以便在Kubernetes集群上与MongoDB Community Edition v8.3 或更高版本一起运行。 mongot进程支持MongoDB Search 和 Vector Search。或者,您可以启用和配置 Vector Search,使用支持的 Voyage AI嵌入模型为集合和查询中的文本数据自动生成向量嵌入。

重要

自动嵌入处于预览状态。在预览期间,该功能和相应的文档可能随时更改。要学习;了解更多信息,请参阅预览功能。

The following procedure demonstrates how to deploy and configure MongoDB Search and Vector Search to run with a new or existing replica set in your Kubernetes cluster. The deployment uses TLS certificates to ensure secure communication between MongoDB nodes and the mongot search process.

要部署MongoDB Search 和 Vector Search,您必须具备以下条件:

  • 正在运行的 Kubernetes 集群。

  • Kubernetes命令行工具 kubectl,配置为与集群通信。

  • Helm( Kubernetes的包管理器),用于安装Kubernetes Operator。

  • cert-manager 或用于 TLS 证书预配的替代证书管理解决方案。

  • Bash v5.1 或更高版本,用于运行本教程中的命令。

或者,要将向量搜索配置为自动为集合和查询中的文本数据生成向量嵌入,您必须为嵌入服务创建API密钥。我们建议创建两个键,一个用于在索引时为集合中的文本数据生成嵌入,另一个用于在查询时为查询文本生成嵌入。如果您没有密钥,可以从Atlas用户界面创建密钥。

设置环境变量以供本过程中的后续步骤使用。复制以下命令,更新环境的值,然后运行这些命令以加载变量:

1# set it to the context name of the k8s cluster
2export K8S_CTX="<local cluster context>"
3
4# the following namespace will be created if not exists
5export MDB_NS="mongodb"

9# Number of replica set members deployed in the sample MongoDBCommunity
10export MDB_MEMBERS=3

44export PROVIDER_ENDPOINT="https://ai.mongodb.com/v1/embeddings"
45export EMBEDDING_MODEL="voyage-4"

注意

如果您有API密钥来启用向量搜索自动生成嵌入,请替换环境变量中的以下占位符值:

AUTO_EMBEDDING_API_QUERY_KEY

用于为查询文本生成嵌入的API密钥。

AUTO_EMBEDDING_API_INDEXING_KEY

在索引时为集合中的文本数据生成嵌入的API密钥。

PROVIDER_ENDPOINT

嵌入模型提供商的终结点。从Atlas用户界面创建的密钥的默认值为 https://ai.mongodb.com/v1/embeddings。如果您直接从 Voyage AI创建API密钥,请替换为 https://api.voyageai.com/v1/embeddings

验证是否已设立环境变量。

要验证是否已设立所有必要的环境变量,请在终端中运行以下代码:

1required=(
2 K8S_CTX
3 MDB_NS
4 MDB_RESOURCE_NAME
5 MDB_VERSION
6 MDB_MEMBERS

20if (( ${#missing_req[@]} )); then
21 echo "ERROR: Missing required environment variables:" >&2
22 for m in "${missing_req[@]}"; do echo " - ${m}" >&2; done
23else
24 echo "All required environment variables present."

Helm 自动部署和管理 Kubernetes 上的 MongoDB 实例。如果您已经拥有包含用于安装 Kubernetes 操作符的 Helm 图表的 Helm 存储库,请跳过此步骤。否则,请添加 Helm存储库。

要添加 Helm存储库,请复制、粘贴并运行以下命令:

1helm repo add mongodb https://mongodb.github.io/helm-charts
2helm repo update mongodb
3helm search repo mongodb/mongodb-kubernetes
3

Kubernetes Operator 监视 MongoDBCommunity 和 MongoDBSearch 自定义资源,并管理MongoDB部署的生命周期。如果您已经安装了MongoDB Controllers for Kubernetes 操作符,请跳过此步骤。否则,请从您在上一步中添加的 Helm存储库安装MongoDB Controllers for Kubernetes Operator。

要在 mongodb 命名空间中安装 MongoDB Controllers for Kubernetes 操作符,请复制、粘贴并运行以下命令:

1helm upgrade --install --debug --kube-context "${K8S_CTX}" \
2 --create-namespace \
3 --namespace="${MDB_NS}" \
4 mongodb-kubernetes \
5 ${OPERATOR_ADDITIONAL_HELM_VALUES:+--set ${OPERATOR_ADDITIONAL_HELM_VALUES}} \
6 "${OPERATOR_HELM_CHART}"
4

在继续MongoDB Search 和 向量搜索部署之前,确保Kubernetes Operator 完全运行。运行以下命令,验证所有操作符组件都在运行且可用。

1kubectl --context "${K8S_CTX}" -n "${MDB_NS}" rollout status --timeout=2m deployment/mongodb-kubernetes-operator
2echo "Operator deployment in ${MDB_NS} namespace"
3kubectl --context "${K8S_CTX}" -n "${MDB_NS}" get deployments
4echo; echo "Operator pod in ${MDB_NS} namespace"
5kubectl --context "${K8S_CTX}" -n "${MDB_NS}" get pods
5

MongoDB需要身份验证才能安全访问权限。在此步骤中,您将创建三个Kubernetes密钥:

  • mdb-admin-user-password: MongoDB管理员的档案。

  • mdb-user-password:授权执行搜索查询的用户的档案。

  • mdbc-rs-search-sync-source-password:专用搜索用户的档案,由 mongot进程在内部用于同步数据和管理索引。

Kubernetes 操作符使用这些密钥中的密码在 MongoDB 数据库中自动创建用户。

要创建密钥,请复制、粘贴并运行以下命令:

1# Create admin user secret
2kubectl create secret generic mdb-admin-user-password \
3 --from-literal=password="${MDB_ADMIN_USER_PASSWORD}" \
4 --dry-run=client -o yaml | kubectl apply --context "${K8S_CTX}" --namespace "${MDB_NS}" -f -
5
6# Create search sync source user secret
7kubectl create secret generic "${MDB_RESOURCE_NAME}-search-sync-source-password" \
8 --from-literal=password="${MDB_SEARCH_SYNC_USER_PASSWORD}" \
9 --dry-run=client -o yaml | kubectl apply --context "${K8S_CTX}" --namespace "${MDB_NS}" -f -
10
11# Create regular user secret
12kubectl create secret generic mdb-user-password \
13 --from-literal=password="${MDB_USER_PASSWORD}" \
14 --dry-run=client -o yaml | kubectl apply --context "${K8S_CTX}" --namespace "${MDB_NS}" -f -
15
16echo "User secrets created."
6

The cert-manager is required for managing TLS certificates. If you already have cert-manager installed in your cluster, skip this step. Otherwise, install cert-manager using Helm.

要在 cert-manager命名空间中安装 cert-manager,请在终端中运行以下命令:

1helm upgrade --install \
2 cert-manager \
3 oci://quay.io/jetstack/charts/cert-manager \
4 --kube-context "${K8S_CTX}" \
5 --namespace "${CERT_MANAGER_NAMESPACE}" \
6 --create-namespace \
7 --set crds.enabled=true
8
9for deployment in cert-manager cert-manager-cainjector cert-manager-webhook; do
10 kubectl --context "${K8S_CTX}" \
11 -n "${CERT_MANAGER_NAMESPACE}" \
12 wait --for=condition=Available "deployment/${deployment}" --timeout=300s
13done
14
15echo "cert-manager is ready in namespace ${CERT_MANAGER_NAMESPACE}."

Create the certificate authority infrastructure that will issue TLS certificates for MongoDB and MongoDBSearch resources. The commands perform the following actions:

  • 创建自签名 ClusterIssuer

  • 生成 CA 证书。

  • 发布所有命名空间都可以使用的集群范围的 CA 颁发者。

  • 通过 ConfigMap 公开 CA 捆绑包,以便MongoDB资源可以使用它。

Issue TLS certificates for both the MongoDB server and the MongoDBSearch service. The MongoDB server certificate includes all necessary DNS names for the pod and service communication. Both certificates support server and client authentication.

如果您已经部署了MongoDB Community Edition,请跳过此步骤。否则,部署MongoDB Community Edition。

要部署MongoDB Community Edition,请完成以下步骤:

  1. 创建名为 mdb-rsMongoDBCommunity 自定义资源。

    该资源定义了 mongodmongodb-agent 容器的 CPU 和内存资源,并设置了以下三个用户:

    mdb-user

    可以恢复数据库和运行搜索查询的用户。该用户使用 mdb-user-password 密钥来执行这些操作。

    search-sync-source

    MongoDB 搜索用于连接到 MongoDB 数据库以管理和构建索引的用户。此用户使用Kubernetes 操作符创建的 searchCoordinator角色。这会使用 mdbc-rs-search-sync-source-password 密钥将 mongot 连接到 mongod

    admin-user

    数据库管理员用户。

    Kubernetes 操作符使用此资源配置具有 3 个成员的 MongoDB 副本集。

    要创建密钥,请复制、粘贴并运行以下命令:

    1kubectl apply --context "${K8S_CTX}" -n "${MDB_NS}" -f - <<EOF

  2. 等待 MongoDBCommunity资源部署完成。

您可以部署一个搜索节点实例,而无需任何负载均衡。

要部署,请完成以下步骤:

  1. 创建名为 mdbc-rs 的 MongoDBSearch 自定义资源。
