如何从本地django连接到docker db？

networks:

  redisnet:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 10.0.0.0/16

这是我的docker-compose.yml文件，我想将位于端口7617上的predixy (集群代理)与django连接，如下所示。

# settings.py
CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://0.0.0.0:7617/",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        },
    }
}

failed to connect to Redis: Connection refused (os error 111)

然而，django似乎无法连接到predixy。

作为您的信息，我还上传了predixy文件。

# docker/predixy/predixy.conf
################################### GENERAL ####################################
## Predixy configuration file example

## Specify a name for this predixy service
## redis command INFO can get this
Name PredixyExample

## Specify listen address, support IPV4, IPV6, Unix socket
## Examples:
# Bind 127.0.0.1:7617
# Bind 0.0.0.0:7617
# Bind /tmp/predixy

## Default is 0.0.0.0:7617
Bind 10.0.0.3:7617

## Worker threads
WorkerThreads 4

## Memory limit, 0 means unlimited

## Examples:
# MaxMemory 100M
# MaxMemory 1G
# MaxMemory 0

## MaxMemory can change online by CONFIG SET MaxMemory xxx
## Default is 0
MaxMemory 0

## Close the connection after a client is idle for N seconds (0 to disable)
## ClientTimeout can change online by CONFIG SET ClientTimeout N
## Default is 0
ClientTimeout 300


## IO buffer size
## Default is 4096
# BufSize 4096

################################### LOG ########################################
## Log file path
## Unspecify will log to stdout
## Default is Unspecified
Log ./predixy.log

## LogRotate support

## 1d rotate log every day
## nh rotate log every n hours   1 <= n <= 24
## nm rotate log every n minutes 1 <= n <= 1440
## nG rotate log evenry nG bytes
## nM rotate log evenry nM bytes
## time rotate and size rotate can combine eg 1h 2G, means 1h or 2G roate a time

## Examples:
# LogRotate 1d 2G
# LogRotate 1d

## Default is disable LogRotate


## In multi-threads, worker thread log need lock,
## AllowMissLog can reduce lock time for improve performance
## AllowMissLog can change online by CONFIG SET AllowMissLog true|false
## Default is true
# AllowMissLog false

## LogLevelSample, output a log every N
## all level sample can change online by CONFIG SET LogXXXSample N
LogVerbSample 0
LogDebugSample 0
LogInfoSample 10000
LogNoticeSample 1
LogWarnSample 1
LogErrorSample 1

        + 10.0.0.15:7005
        + 10.0.0.16:7006
    }
}

我该如何解决这个问题？我在努力解决这个问题。我想要的是访问docker-cli并连接到redis-cli -h 10.0.0.3 -p 7617，这样我就可以看到从本地django输入的数据。

用predixy替换0.0.0.0，如下所示

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://predixy:7617/",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        },
    }
}
