我正在尝试建立一个集群，其中有一个射线头和两个带有docker swarm的射线 worker 。为此，我有三台机器，其中一台运行射线防护仪，另一台运行两台射线防护仪。群集运行正常，但是每当我执行到容器并运行时:
import ray
ray.init(redis-address='ray-head:6379')
我得到
WARNING worker.py:1274 -- Some processes that the driver needs to connect to have not registered with Redis, so retrying. Have you run 'ray start' on this node?
容器的原木没有问题。
我也有IP，光线头容器的机器和ip。
ray.init(redis-address='192.168.30.193:6379')
运行时:
telnet 192.168.30.193 6379
有一个答案。
容器的Dockerfile:
FROM python:2.7-slim
RUN apt-get -y update
RUN apt-get install -y --fix-missing \
libxml2 \
gcc \
vim \
iputils-ping \
telnet \
procps \
&& apt-get clean && rm -rf /tmp/* /var/tmp/*
RUN pip install ray
CMD ["echo", "Base Image Ready"]
docker-compose.yml

我做错了吗？任何使它能够以群集模式工作的人。

我知道现在不起作用的原因，但不知道如何解决。
如果我登录到头容器并检查ray进程正在运行的ip
ray/monitor.py --redis-address=10.0.30.5:6379
这个匹配
/# ping ray-head
PING ray-head (10.0.30.5) 56(84) bytes of data.
64 bytes from 10.0.30.5 (10.0.30.5): icmp_seq=1 ttl=64 time=0.105 ms
但这不匹配
/hostname -i
10.0.30.6
如果我将射线过程从--redis-address = 10.0.30.6:6379开始
有用。
最佳答案
我发现了解决方法:
ray-head容器的主机名不是“ray-head”，而是“tasks.ray-head”。
为了使其工作，我需要像这样更改docker-compose文件中的主机名:
对于射线头:
command: ['start', '--head', '--redis-port', '6379', '--redis-shard-ports','6380,6381', '--object-manager-port','12345', '--node-manager-port','12346', '--node-ip-address', 'tasks.ray-head', '--block']
对于射线 worker :
command: ['start', '--redis-address', 'tasks.ray-head:6379', '--object-manager-port', '12345', '--node-manager-port', '12346', '--block']
现在，我可以在任何主机上运行它:
ray.init('tasks.ray-head:6379')
我希望这可以帮助处于相同情况的其他人
