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

ARG CRONICLE_VERSION=v0.8.28 ENV CRONICLE_VERSION=${CRONICLE_VERSION}

RUN curl -sL https://deb.nodesource.com/setup_16.x | bash - \ && apt-get install -y nodejs \ && curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - \ && echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list \ && apt-get update && apt-get install -y yarn

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

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).
