Implementar pesquisa e Vector Search

Instalar e usar a pesquisa com o MongoDB Enterprise Edition

Você pode usar o Kubernetes Operator para implantar recursos do MongoDB Search e Vector Search para serem executados com o MongoDB Enterprise v8.0.10 ou superior em um cluster do Kubernetes. Este procedimento demonstra como implantar e configurar o processo mongot para ser executado com um conjunto de réplicas novo ou existente em seu cluster Kubernetes.

Importante

O suporte para versões do MongoDB inferiores a 8.2 está agora obsoleto. Atualize para o MongoDB v8.2 ou posterior.

Pré-requisitos

Para implantar o MongoDB Search e o Vector Search, você deve ter o seguinte:

  • Um cluster Kubernetes em execução com kubeconfig disponível localmente.

  • A ferramenta de linha de comando do Kubernetes, kubectl, configurada para se comunicar com seu cluster.

  • Helm, o gerenciador de pacote do Kubernetes, para instalar o Operador Kubernetes.

  • Bash v5.1 ou superior para executar os comandos neste tutorial.

  • projeto do MongoDB Ops Manager ou do MongoDB Cloud Manager e credenciais de API.

Procedimento

1

Obrigatório. Defina as variáveis de ambiente.

Para definir as variáveis de ambiente para uso nas etapas subsequentes deste procedimento, copie o seguinte, defina os valores para as variáveis de ambiente e carregue as variáveis de ambiente:

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"
6
7# name of the MongoDB Custom Resource.
8export MDB_RESOURCE_NAME="mdb-rs"
9
10# OM/CM's project name to be used to manage mongodb replica set
11export OPS_MANAGER_PROJECT_NAME="<arbitrary project name>"
12
13# URL to Cloud Manager or Ops Manager instance
14export OPS_MANAGER_API_URL="https://cloud-qa.mongodb.com"
15
16# The API key can be an Org Owner - the operator can create the project automatically then.
17# The API key can also be created in a particular project that was created manually with the Project Owner scope.
18export OPS_MANAGER_API_USER="<SET API USER>"
19export OPS_MANAGER_API_KEY="<SET API KEY>"
20export OPS_MANAGER_ORG_ID="<SET ORG ID>"
21
22# minimum required MongoDB version for running MongoDB Search is 8.2.0
23export MDB_VERSION="8.2.0-ent"
24
25# root admin user for convenience, not used here at all in this guide
26export MDB_ADMIN_USER_PASSWORD="admin-user-password-CHANGE-ME"
27# regular user performing restore and search queries on sample mflix database
28export MDB_USER_PASSWORD="mdb-user-password-CHANGE-ME"
29# user for MongoDB Search to connect to the replica set to synchronise data from
30export MDB_SEARCH_SYNC_USER_PASSWORD="search-sync-user-password-CHANGE-ME"
31
32export OPERATOR_HELM_CHART="mongodb/mongodb-kubernetes"
33# comma-separated key=value pairs for additional parameters passed to the helm-chart installing the operator
34export OPERATOR_ADDITIONAL_HELM_VALUES=""
35
36export MDB_CONNECTION_STRING="mongodb://mdb-user:${MDB_USER_PASSWORD}@${MDB_RESOURCE_NAME}-svc.${MDB_NS}.svc.cluster.local:27017/?replicaSet=${MDB_RESOURCE_NAME}"

Condicional. Adicione o repositório do MongoDB Helm.

O Helm automatiza a implantação e o gerenciamento de instâncias do MongoDB no Kubernetes. Se você já adicionou o repositório Helm que contém o gráfico Helm para instalar o operador Kubernetes Operator, pule esta etapa. Caso contrário, adicione o repositório Helm.

Para adicionar, copie, cole e execute o seguinte comando:

1helm repo add mongodb https://mongodb.github.io/helm-charts
2helm repo update mongodb
3helm search repo mongodb/mongodb-kubernetes
1"mongodb" has been added to your repositories
2Hang tight while we grab the latest from your chart repositories...
3...Successfully got an update from the "mongodb" chart repository

Condicional. Instale os drivers do MongoDB para o Kubernetes Operator.

O Operador Kubernetes observa MongoDB, MongoDBOpsManager e MongoDBSearch recursos personalizados e gerencia o ciclo de vida de suas implantações do MongoDB . Se você já instalou os Controladores MongoDB para Kubernetes Operator, pule esta etapa. Caso contrário, instale os Controladores MongoDB para Kubernetes Operator a partir do repositório Helm que você adicionou na etapa anterior.

Para instalar os Controladores MongoDB para o Operador Kubernetes no namespace do mongodb, copie, cole e execute o seguinte:

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}"
1Release "mongodb-kubernetes" does not exist. Installing it now.

Condicional. Crie e implemente o recurso MongoDB Enterprise .

Se você já implementou o MongoDB Enterprise, pule para a próxima etapa. Caso contrário, implemente o recurso MongoDB Enterprise .

Para implementar o MongoDB Enterprise, complete as seguintes etapas:

  1. Crie o ConfigMap e o segredo para o projeto MongoDB Ops Manager se estiver usando o MongoDB Ops Manager.

    Para armazenar a configuração e as credenciais para integração com o MongoDB Ops Manager, copie, cole e execute os seguintes comandos:

    1kubectl --context "${K8S_CTX}" -n "${MDB_NS}" create configmap om-project \
    2  --from-literal=projectName="${OPS_MANAGER_PROJECT_NAME}" --from-literal=baseUrl="${OPS_MANAGER_API_URL}" \
    3  --from-literal=orgId="${OPS_MANAGER_ORG_ID:-}"
    4
    5kubectl --context "${K8S_CTX}" -n "${MDB_NS}" create secret generic om-credentials \
    6  --from-literal=publicKey="${OPS_MANAGER_API_USER}" \
    7  --from-literal=privateKey="${OPS_MANAGER_API_KEY}"

  2. Crie um recurso personalizado do MongoDB denominado mdb-rs.

    O recurso define os recursos de memória e CPU para os containers mongod e mongodb-agent e instrui o Operador Kubernetes a configurar um conjunto de réplicas do MongoDB com membros 3:

    Para implantar o MongoDB Enterprise, copie, cole e execute o seguinte no namespace:

    1kubectl apply --context "${K8S_CTX}" -n "${MDB_NS}" -f - <<EOF
    2apiVersion: mongodb.com/v1
    3kind: MongoDB
    4metadata:
    5  name: ${MDB_RESOURCE_NAME}
    6spec:

    8  version: ${MDB_VERSION}
    9  type: ReplicaSet
    10  opsManager:

    13  credentials: om-credentials
    14  security:
    15    authentication:
    16      enabled: true
    17      ignoreUnknownUsers: true
    18      modes:
    19      - SCRAM
    20  agent:
    21    logLevel: INFO
    22  podSpec:
    23    podTemplate:
    24      spec:
    25        containers:
    26        - name: mongodb-enterprise-database
    27          resources:
    28            limits:
    29              cpu: "2"
    30              memory: 2Gi
    31            requests:
    32              cpu: "1"
    33              memory: 1Gi
    34EOF

  3. Aguarde a conclusão do sistema de recursos MongoDB.

    Quando você aplica o recurso personalizado do MongoDB, o operador Kubernetes começa a distribuir os nós MongoDB (Pods). Essa etapa pausa a execução até que a fase de status do recurso mdbc-rs seja Running, o que indica que o conjunto de réplicas da MongoDB Community está operacional.

    1echo "Waiting for MongoDB resource to reach Running phase..."
    2kubectl --context "${K8S_CTX}" -n "${MDB_NS}" wait --for=jsonpath='{.status.phase}'=Running "mdb/${MDB_RESOURCE_NAME}" --timeout=400s
    3echo; echo "MongoDB resource"
    4kubectl --context "${K8S_CTX}" -n "${MDB_NS}" get "mdb/${MDB_RESOURCE_NAME}"
    5echo; echo "Pods running in cluster ${K8S_CTX}"
    6kubectl --context "${K8S_CTX}" -n "${MDB_NS}" get pods

Obrigatório. Crie e carregue os segredos de usuário MongoDB .

O MongoDB requer autenticação para acesso seguro. Nesta etapa, você cria três segredos do Kubernetes:

  • mdb-admin-user-password: Credenciais do administrador do MongoDB .

  • mdb-user-password: Credenciais do usuário autorizado a realizar queries de pesquisa.

  • mdbc-rs-search-sync-source-password: Credenciais para um usuário de pesquisa dedicado utilizado internamente pelo processo do mongot para sincronizar dados e gerenciar índices.

O Kubernetes Operator monta esses segredos nos pods do MongoDB .

Para criar os segredos, copie, cole e execute o seguinte no namespace onde você distribuiu o MongoDB Server e planeja implantar a Pesquisa MongoDB e a Vector Search:

1# admin user with root role
2kubectl --context "${K8S_CTX}" --namespace "${MDB_NS}" \
3  create secret generic mdb-admin-user-password \

Obrigatório. Crie e implemente o recurso para MongoDB Search e Vector Search.

Você pode implementar uma instância do nó de pesquisa sem nenhum balanceamento de carga. Para implantar, conclua as seguintes etapas:

  1. Crie um recurso personalizado do MongoDBSearch denominado mdbc-rs.

    Este recurso especifica os requisitos de recursos de CPU e memória para os nós de pesquisa. Para saber mais sobre as configurações neste recurso personalizado, consulte Configurações de pesquisa do MongoDB e Vector Search.

    1kubectl apply --context "${K8S_CTX}" -n "${MDB_NS}" -f - <<EOF
    2apiVersion: mongodb.com/v1
    3kind: MongoDBSearch
    4metadata:
    5  name: ${MDB_RESOURCE_NAME}
    6spec:
    7  # no need to specify source.mongodbResourceRef if MongoDBSearch CR has the same name as MongoDB CR
    8  # the operator infer it automatically
    9  resourceRequirements:
    10    limits:
    11      cpu: "3"
    12      memory: 5Gi
    13    requests:
    14      cpu: "2"
    15      memory: 3Gi
    16EOF

  2. Aguarde a conclusão do sistema de recursos MongoDBSearch.

    Quando você aplica o recurso personalizado do MongoDBSearch, o operador do Kubernetes começa a distribuir os nós de pesquisa (Pods). Essa etapa pausa a execução até que a fase de status do recurso mdbc-rs seja Running, o que indica que o conjunto de réplicas da MongoDB Community está operacional.

    1echo "Waiting for MongoDBSearch resource to reach Running phase..."
    2kubectl --context "${K8S_CTX}" -n "${MDB_NS}" wait --for=jsonpath='{.status.phase}'=Running "mdbs/${MDB_RESOURCE_NAME}" --timeout=300s
7

Opcional. Verifique o status do recurso MongoDB Enterprise .

Certifique-se de que a implantação do recurso MongoDB com MongoDBSearch tenha sido bem-sucedida.

1echo "Waiting for MongoDB resource to reach Running phase..."
2kubectl --context "${K8S_CTX}" -n "${MDB_NS}" wait --for=jsonpath='{.status.phase}'=Running "mdb/${MDB_RESOURCE_NAME}" --timeout=400s

Opcional. Visualize todos os pods em execução em seu namespace.

Visualize todos os pods em execução nos pods do seu namespace para os nós do conjunto de réplicas do MongoDB , o operador do MongoDB Controladores for Kubernetes e os nós de pesquisa.
