Redis配置为保存RDB快照，但目前无法在磁盘上持久化-Ubuntu Server

Question

我使用的是redis alpine的容器，在生产过程中——在我的服务器上——出现了这个错误。我发现Miscf Redis配置为保存RDB快照，并进行了检查，但其中的建议都不起作用。

这是错误消息：

    $ node dist/queue.js

events.js:174
      throw er; // Unhandled 'error' event
      ^
ReplyError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

出现此错误的原因之一是当您使用Redis容器时，没有受到攻击的卷。要解决此问题，只需将以下行放入docker compose文件：

volumes:
    - "./redis-data:/data"
