Summary
Hi guys,
I'm new bie of docker
I want to setup cronicle running on 2 servers with load balancer nginx. But now I get error: WebSocket connection to 'ws://172.19.0.2:3012/socket.io/?EIO=4&transport=websocket' failed: WebSocket is closed before the connection is established.
My Setup
- Create 2 VM centos 7 with IP: 172.16.10.104, 172.16.10.105
Image of cronicle:
FROM python:3.6
ARG CRONICLE_VERSION=v0.8.28
ENV CRONICLE_VERSION=${CRONICLE_VERSION}

RUN curl -s "https://raw.githubusercontent.com/jhuckaby/Cronicle/${CRONICLE_VERSION}/bin/install.js" | node

Hmmm, I have no idea, but do check out @mikeTWC1984's fork over at: https://github.com/cronicle-edge/cronicle-edge/tree/main/Docker
He seems to have multi-server docker figured out quite nicely (using swarm).
