Question

我的build.sh文件中有这个

docker run -d --restart always --name $APP \
   --link euvat:euvat \
   --link freegeoip:freegeoip \
   --link redis-$TYPE:redis \
   --link mongo-$TYPE:mongo \
   --env VIRTUAL_HOST=$TYPE.domain.tld \
   --env-file $APPENV \
   $IMAGE

但是由于某些原因，链接到mongo和redis不断中断，并且出现错误：

[== tailing docker logs press [Ctrl + C] to cancel ==]

    at _combinedTickCallback (internal/process/next_tick.js:74:11)
    at process._tickDomainCallback [as _tickCallback] (internal/process/next_tick.js:122:9)

如果我重新启动容器，则会松动Redis

Error: Redis connection to redis:6379 failed - connect EHOSTUNREACH 172.17.0.5:6379
    at Object.exports._errnoException (util.js:1023:11)
    at exports._exceptionWithHostPort (util.js:1046:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1090:14)

这是一台旧服务器，应进行升级

 $ docker version

这是正在运行的容器：

链接这些容器或解决此问题的正确方法是什么？

无法重新链接Docker容器
