Docker Toolbox for Windows, Swarm mode, services connection refused #2914

Closed mechdeveloper closed 5 years ago

Docker toolbox for windows Services are refusing connection when using swarm mode on Docker toolbox for Windows

Note: (docker toolbox) Docker is running in a linux VM inside my local machine with an ip address of 192.168.99.101

Steps to Reproduce the issue -

Step 1: Initialize the swarm mode $ docker swarm init --advertise-addr 192.168.99.101 Swarm initialized: current node (yfgi1sjocv9jq74e97g6ya9fm) is now a manager.

Step 2: pull an nginx image $ docker pull nginx Using default tag: latest latest: Pulling from library/nginx a5a6f2f73cd8: Pull complete 1ba02017c4b2: Pull complete 33b176c904de: Pull complete Digest: sha256:5d32f60db294b5deb55d078cd4feb410ad88e6fe77500c87d3970eca97f54dba Status: Downloaded newer image for nginx:latest

Step 3: create nginx service and expose it to port 7070 $ docker service create --name svcnginx -p 7070:80 nginx 1rmtfr7hs0oashfmg6ty57nox overall progress: 1 out of 1 tasks 1/1: running verify: Service converged

Step 4: Check the service we just created $ docker service ls ID NAME MODE REPLICAS IMAGE PORTS 1rmtfr7hs0oa svcnginx replicated 1/1 nginx:latest *:7070->80/tcp

Step 5: Check the containers $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 1d681e3d0ea7 nginx:latest "nginx -g 'daemon of" 16 seconds ago Up 15 seconds 80/tcp svcnginx.1.58wzzqwbrcd3vmt9ymyxy2mmn

Step 6: Try to access the running nginx service $ curl $(docker-machine ip default):7070 curl: (7) Failed to connect to 192.168.99.101 port 7070: Connection refused

Expected O/P: $ curl 192.168.99.101:7070 <!DOCTYPE html>

I am new to docker not really sure what i am doing wrong. Practiced these same steps here "https://www.katacoda.com/courses/docker/playground" and everything work fine.

Running standalone nginx contianer also works fine without creating service $ docker run -d -p 7000:80 nginx

Update: this works on a public network but fails on a protected network. I am still trying to understand what is wrong with the machines on protected networks which prevents docker swarm mode services to work.

I tried the same scenario in my personal windows machine and it worked fine.

Update I found this-

Docker Swarm's routing mesh feature is not yet supported on Windows, but users seeking to publish ports for their service endpoints can do so today using publish-port mode.

refer this link https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-containers/swarm-mode#publish-ports-for-service-endpoints

The problem was proxy settings on the boot2docker vm i was running.
