可以将redis模块(redisbloom)加载到redis helm图表(bitnami/redis或bitnami/redis-cluster)上吗？

Question

我正在尝试将redisbloom模块添加到redis helm图表(bitnami/ redis )中，或者理想情况下添加到redis集群图表(bitnami/redis- cluster )中。

# Chart.yaml

apiVersion: v2
name: my-app
description: My app and redis (with redisbloom module loaded)
type: application
version: 0.1.0
appVersion: 0.1.0
dependencies:
  - name: redis
    alias: redisbloom
    version: 12.1.1
    repository: https://charts.bitnami.com/bitnami

将编译后的模块redisbloom.so复制到每个pod，然后在启动后或使用master.command=redis-server --load-module=<path>/redisbloom.so加载模块似乎是一个潜在的解决方案-然而，从文档中我看不到如何复制图表的二进制文件。

我也不确定这是否足以满足主从式或集群模式的需要。这个Github issue表明这应该是可能的-但遗憾的是，我找不到支持它的文档。

有可能吗？或者，我是否需要创建自定义图表，例如，使用RedisBloom docker映像redislabs/rebloom

提前谢谢。

我认为您需要基于带有所需模块的bitnami映像构建自定义redis映像，然后使用extraVars变量指定您的模块，如下所示：--loadmodule /usr/lib/redis/modules/redisearch.so

我的Dockerfile (我需要有redisearch模块)：
