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

Question

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

# 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

将已编译的模块

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

加载模块似乎可能是一个潜在的解决方案 - 但是从文档中我看不到如何复制二进制文件图表。

我也不确定这本身是否足以满足主从或集群情况的工作。这个Github问题表明应该可以做到 - 但可惜我找不到支持它的文档。

可能吗？或者我是否需要创建一个自定义图表，例如使用 RedisBloom docker 映像 [redislabs/rebloom]？

提前致谢。

我认为您需要基于具有所需模块的 bitnami 映像构建自定义 Redis 映像，然后使用 extraVars var 指定您的模块，例如： --loadmodule /usr/lib/redis/modules/redisearch.so

我的 Dockerfile（我需要有 redisearch 模块）：

#### My customization
FROM redislabs/redisearch:latest AS moduleimg
#### End of
FROM docker.io/bitnami/minideb:buster
LABEL maintainer "Bitnami <[email protected]>"

ENV HOME="/" \

Answer 2

我会使用自定义图像，例如：

FROM redislabs/rebloom:latest as builder

FROM bitnami/redis:6.2.10
COPY --from=builder /usr/lib/redis/modules/redisbloom.so /usr/lib/redis/modules/redisbloom.so

CMD ["/run.sh", "--loadmodule", "/usr/lib/redis/modules/redisbloom.so"]

在我的想法中，您必须基于具有所需模块的 bitnami Redis 映像构建自定义 Redis 映像，之后，您必须在 helm 图表配置上添加一些配置以加载自定义模块，这是 redisearch 的完整示例：

# Copyright VMware, Inc.
# SPDX-License-Identifier: APACHE-2.0

    ) && \
    for COMPONENT in "${COMPONENTS[@]}"; do \
      if [ ! -f "${COMPONENT}.tar.gz" ]; then \
        curl -SsLf "https://downloads.bitnami.com/files/stacksmith/${COMPONENT}.tar.gz" -O ; \

      rm -rf "${COMPONENT}".tar.gz{,.sha256} ; \
    done
RUN apt-get autoremove --purge -y curl && \
    apt-get update && apt-get upgrade -y && \
    apt-get clean && rm -rf /var/lib/apt/lists /var/cache/apt/archives
RUN chmod g+rwX /opt/bitnami
RUN ln -s /opt/bitnami/scripts/redis/entrypoint.sh /entrypoint.sh

COPY rootfs /

ENV APP_VERSION="7.2.3" \
    BITNAMI_APP_NAME="redis" \
    PATH="/opt/bitnami/common/bin:/opt/bitnami/redis/bin:$PATH"

### My customization
RUN mkdir /opt/bitnami/redis/modules
COPY --from=searchmoduleimg /usr/lib/redis/modules/redisearch.so* /opt/bitnami/redis/modules

### End of

EXPOSE 6379

USER 1001
ENTRYPOINT [ "/opt/bitnami/scripts/redis/entrypoint.sh" ]
CMD [ "/opt/bitnami/scripts/redis/run.sh"]

构建 iamge 后，将这些行添加到 script-config.yaml 中的 start-master.sh 和 start-replica.sh 中：

exec redis-server \
--loadmodule /opt/bitnami/redis/modules/redisearch.so MAXSEARCHRESULTS 10000 MAXAGGREGATERESULTS 10000 \
"${ARGS[@]}"
{{- end }}

现在您可以使用自定义 mosule。
