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 v8.2.0 ou superior em um cluster do Kubernetes. Este procedimento demonstra como implantar e configurar o mongot processo para ser executado com um conjunto de réplicas novo ou existente em seu cluster Kubernetes. A implantação usa certificadosTLS para garantir uma comunicação segura entre os nós do MongoDB e o mongot processo de pesquisa.

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 MongoDB Ops Manager ou MongoDB Cloud Manager e credenciais de API.

Procedimento

1

Obrigatório. Defina as variáveis de ambiente.

Defina as variáveis de ambiente para uso nas etapas subsequentes deste procedimento. Copie os seguintes comandos, atualize os valores do seu ambiente e execute-os para carregar as variáveis:

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
10export MDB_MEMBERS=3
11# OM/CM's project name to be used to manage mongodb replica set
12export OPS_MANAGER_PROJECT_NAME="<arbitrary project name>"
13
14# URL to Cloud Manager or Ops Manager instance
15export OPS_MANAGER_API_URL="https://cloud-qa.mongodb.com"
16
17# The API key can be an Org Owner - the operator can create the project automatically then.
18# The API key can also be created in a particular project that was created manually with the Project Owner scope.
19export OPS_MANAGER_API_USER="<SET API USER>"
20export OPS_MANAGER_API_KEY="<SET API KEY>"
21export OPS_MANAGER_ORG_ID="<SET ORG ID>"
22
23# minimum required MongoDB version for running MongoDB Search is 8.2.0
24export MDB_VERSION="8.2.0-ent"
25
26# root admin user for convenience, not used here at all in this guide
27export MDB_ADMIN_USER_PASSWORD="admin-user-password-CHANGE-ME"
28# regular user performing restore and search queries on sample mflix database
29export MDB_USER_PASSWORD="mdb-user-password-CHANGE-ME"
30# user for MongoDB Search to connect to the replica set to synchronise data from
31export MDB_SEARCH_SYNC_USER_PASSWORD="search-sync-user-password-CHANGE-ME"
32
33export OPERATOR_HELM_CHART="mongodb/mongodb-kubernetes"
34# comma-separated key=value pairs for additional parameters passed to the helm-chart installing the operator
35export OPERATOR_ADDITIONAL_HELM_VALUES=""
36
37export MDB_TLS_CERT_SECRET_PREFIX="certs"
38export MDB_TLS_CA_CONFIGMAP="${MDB_RESOURCE_NAME}-ca-configmap"
39
40export CERT_MANAGER_NAMESPACE="cert-manager"

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...

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}"

Condicional. Instale cert-manager o.

O cert-manager é necessário para gerenciar certificados TLS. Se você já tiver cert-manager o instalado em seu cluster, pule esta etapa. Caso contrário, instale cert-manager usando o Helm.

Para instalar o cert-manager no namespace cert-manager, execute o seguinte comando em seu terminal:

1helm upgrade --install \
2  cert-manager \
3  oci://quay.io/jetstack/charts/cert-manager \
4  --kube-context "${K8S_CTX}" \

Obrigatório. Prepare o emissor do certificado e a infraestrutura da CA.

Crie a infraestrutura da autoridade de certificação que emitirá certificados TLS MongoDB para MongoDBSearch recursos e. Os comandos executam as seguintes ações:

  • Crie um ClusterIssuer autoassinado.

  • Gere um certificado CA.

  • Publique um emissor de CA em todo o cluster que todos os namespaces possam usar.

  • Exponha o pacote CA por meio de um ConfigMap para que os recursos do MongoDB possam usá-lo.

Obrigatório. Emita certificados TLS.

Emita certificados TLS para o servidor MongoDB (${MDB_RESOURCE_NAME}-server-tls) e o serviço MongoDBSearch (${MDB_RESOURCE_NAME}-search-tls). O certificado de servidor MongoDB inclui todos os nomes de DNS necessários para o pod e a comunicação de serviço. Ambos os certificados dão suporte à autenticação de servidor e cliente.

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:-}"

    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

    38EOF

  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

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

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.

    Quando você aplica o recurso personalizado MongoDBSearch, o operador Kubernetes começa a implantar 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

Opcional. Verifique o status do recurso MongoDB Enterprise .

Certifique-se de que a implementação do recurso MongoDB com o 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
11

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.
