يعطي ما يلي بلا نهاية:
Job exception: 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.

من الواضح أن هذه مشكلة في Redis وأعتقد أنه يتم إنهاؤه بطريقة ما، ولكنه لا يبدو أنه من سجل النواة خارج حاوية docker، ومع ذلك داخل حاوية docker أرى:

ليس رائعًا، ولكنه ليس سيئًا على ما يبدو.
