问题 I'm trying to setup a light-weight RQ task queue app running in Docker. I keep on getting this error: ValueError: Redis URL must specify one of the following schemes (redis://, rediss://, unix://) When grabbing from environmental variable ( os.getenv() ) it doesn't work, but somehow when hard-coding in redis://redis:6379/0 , it seems to work. However, this is not really a long-term solution in my opinion. I looked at: link1 and link2, but there wasn't really a solution, the thread went dead.

问题 In "naked" Docker, I can use --network=host to make the host reachable from the container through the docker0 interface at 127.0.0.1 , or I can reach the host at 172.17.0.1 . Ostensibly docker-compose supports the host networking driver through network_mode: host . Unfortunately, this prevents me from using exposed ports. Containers created using docker-compose don't live on the docker0 interface, and hence can reach the host at some IP address like 172.18.0.1 or 172.19.0.1 , decided at

问题 On <Container Id>-json.log finding some entries with INFO and WARNING with stream as stderr. Actually, these have to be with stream as stdout. Can anybody give a clue to where exactly I need to look into this? Is this docker related configuration or my application related configuration? Example, {"log":"[2020/02/20-08:50:26,557]-[**INFO** ]-[362]-[testlogger]--4: 202a68dfd8621ee9de1a7ff4\n","stream":"stderr","time":"2020-02-20T08:50:26.55867314Z"} 来源： https://stackoverflow.com/questions

问题 How can I access the host ARP records from within a Docker container? I tried to mount a volume (in a docker-compose file) /proc/net/arp:/proc/net/arp but found out that I can't make any volume with /proc . Then I tried to mount it elsewhere like /proc/net/arp:/root/arp , but then if I cat /root/arp , from within the container, the table comes out empty. docker run -v /proc/net/arp:/root/arp alpine cat /root/arp <-- returns empty table Ideas? 回答1: You should be good if you add privileged mode
