Redis在Docker容器中沒有附加自定義redis.conf文件

Question

我在獲取redis以在Docker容器中啓動時遇到問題。當我運行

docker-compose up 

我看到輸出

Starting redis_redis_1 
Attaching to redis_redis_1 
redis_redis_1 exited with code 0 

之後，我可以運行

docker ps -a 

看到

這是我的碼頭工人，compose.yml

redis: 
    image: redis 
    command: redis-server /usr/local/etc/redis/redis.conf 
    ports: 
     - "6379:6379" 
    volumes: 
     - /mnt/xvdb/redis/:/usr/local/etc/redis/ 
     - ./redis/redis.conf:/usr/local/etc/redis/redis.conf 

這是詳細的輸出，我得到：

搬運工日誌給我什麼

docker logs redis_redis_1 

給我什麼

因此，我能夠讓Redis以我認爲是默認配置文件的方式運行。因爲第一行顯示警告。

Redis must be restarted after THP is disabled.

這是什麼導致我的redis.conf文件在我原來的問題，我已經覆蓋默認命令。

之後我能夠檢查默認配置文件中的實際內容。

docker exec db00a03fd187 cat /usr/local/etc/redis/redis.conf 

找到我的自定義配置文件被使用。

因此，因爲我正在將我的配置文件映射到默認目錄，所以我想我會得到那個輸出。所以，沒有問題。

下面是我結束了我的搬運工，compose.yml文件：

redis: 
    image: redis 
    ports: 
     - "6379:6379" 
    volumes: 
     - ./redis/redis.conf:/usr/local/etc/redis/redis.conf 
     - /mnt/xvdb/redis:/usr/local/etc/redis
