Part1 shows how to create a username/repository:tag but it doesn’t say what the :tag should be. Should it always be :tag or should it be my version #. Or something else? I am working through the part 3 of the docker get started tutorial. Everything was working great till I needed to test my swarm w…

@denisroy I mean its exactly the same as the tutorial. docker-compose.yml iversion: "3" services: web: image: mjwrazor/repository:4 deploy: replicas: 5 resources: limits: cpus: "0.1" memory: 50M restart_policy: condition: on-fai…

[image] mjwrazor: There is no extension on the Dockerfile right? No extension, that’s correct. Error response from daemon: This node is already part of a swarm. Use "docker swarm l join another one. That happens when you run docker swarm init more than once. If you need to restart the tut…

Still the same response. I only ever get the same container ID it never load balances. @denisroy . Fallowing the tutorial step by step. It shows I have 5 instances if I use docker stack ps getstartedlab using the browser or curl will only ever show the same string.

Im getting the usual connected refused at localhost:4000 and localhost:80. I am using ubuntu 16.04. I have apache installed…

Hi there! Part 3 “Services”… all is running and fine BUT why my service is SIGNIFICANTLY slower than my container? Response from service: curl -o /dev/null -s -w %{time_total}\\n http://localhost 40.049 Response just from running container (tutorial part 2): curl -o /dev/null -s -w %{time_total…

Hello guys, I ran in the same issue, I didn’t investigate too much yet but I was getting nothing out of localhost (hitting port 80). So, if you want to progress in the tutorial, go in docker-compose.yml and change: “80:80" by "4000:80” Then hit localhost:4000 I’ll update if I find something …

Ran into the same issue for Part 4. I tried on both Win10 and Ubuntu 16.04. Why have nobody given out the solution for half a year? It is a just easy tutorial.
