安装 Redis Enterprise Helm 图表

使用 Helm 图表安装 Redis Enterprise for Kubernetes 版本 7.8.6。

适用于 Kubernetes 的 Redis Enterprise

Helm 图表提供了一种简单的方法，只需几个步骤即可安装 Redis Enterprise for Kubernetes Operator。有关 Helm 的更多信息，请转到 https://helm.sh/docs/。

注意：
此功能目前为公共预览版，在生产工作负载上不受支持。目前仅支持 Redis 运算符的新安装。创建 RedisEnterpriseCluster （REC） 和其他自定义资源的步骤保持不变。

先决条件

示例值

以下步骤使用以下占位符来指示您必须提供的命令行参数：

  • <repo-name>是保存 Helm Chart 的存储库的名称（例如：redis).
  • <release-name>是您为 Helm Chart 的特定安装指定的名称（例如：my-redis-enterprise-operator)
  • <chart-version>是要安装的 Helm Chart 的版本（例如：7.8.2-2)
  • <namespace-name>是 Redis 运算符将在其中运行的新命名空间的名称（例如：ns1)
  • <path-to-chart>是 Helm Chart 的文件路径，如果它存储在本地目录中（例如：/home/charts/redis-enterprise-operator)

安装

  1. 添加 Redis 存储库。
helm repo add <repo-name> https://helm.redis.io/
  1. Install the Helm chart into a new namespace.
helm install <release-name> redis/redis-enterprise-operator \
    --version <chart-version> \
    --namespace <namespace-name> \
    --create-namespace

To install with Openshift, add --set openshift.mode=true.

To monitor the installation add the --debug flag. The installation runs several jobs synchronously and may take a few minutes to complete.

Install from local directory

  1. Find the latest release on the redis-enterprise-k8s-docs repo and download the tar.gz source code into a local directory.

  2. Install the Helm chart from your local directory.

helm install <release-name> <path-to-chart> \
    --namespace <namespace-name> \
    --create-namespace

To install with Openshift, add --set openshift.mode=true.

To monitor the installation add the --debug flag. The installation runs several jobs synchronously and may take a few minutes to complete.

Specify values during install

  1. View configurable values with helm show values <repo-name>/<chart-name>.

  2. Install the Helm chart, overriding specific value defaults using --set.

helm install <operator-name> redis/redis-enterprise-operator \
    --version <release-name> \
    --namespace <namespace-name> \
    --create-namespace
    --set <key1>=<value1> \
    --set <key2>=<value2>

Install with values file

  1. View configurable values with helm show values <repo-name>/<chart-name>.

  2. Create a YAML file to specify the values you want to configure.

  3. Install the chart with the --values option.

helm install <operator-name> redis/redis-enterprise-operator \
    --version <release-name> \
    --namespace <namespace-name> \
    --create-namespace \
    --values <path-to-values-file>

Uninstall

  1. Delete any custom resources managed by the operator. See Delete custom resources for detailed steps. You must delete custom resources in the correct order to avoid errors.

  2. Uninstall the Helm chart.

helm uninstall <release-name>

This removes all Kubernetes resources associated with the chart and deletes the release.

Note:
Custom Resource Definitions (CRDs) installed by the chart are not removed during chart uninstallation. To remove them manually after uninstalling the chart, run kubectl delete crds -l app=redis-enterprise.

Known limitations

  • Only new installations of the Redis operator are supported at this time. The steps for creating the RedisEnterpriseCluster (REC) and other custom resources remain the same.
  • Upgrades and migrations are not supported.
  • The chart doesn't include configuration options for multiple namespaces, rack-awareness, and Vault integration. The steps for configuring these options remain the same.
  • The chart has had limited testing in advanced setups, including Active-Active configurations, air-gapped deployments, and IPv6/dual-stack environments.
