Part 4 doesn't include instructions to change the port forwarding to 80:80 in this section. The screenshot is a bit misleading if you're coming directly from part 3 and have port 4000 still forwarding to port 80.
When you use `docker service ls`, it won't show you the list of services. Instead use `docker stack services getstartedlab` to show the service that was created and thereby getting the Service ID of it.
As this is an introductory document, using short options
and relying on default behaviors without explanation
may cause some confusion.
This change it explicit how the --tag option is being used.
It also uses an equal sign to visually group the option and its value,
so that the . at the end of the command doesn't go unnoticed.
Fixed a typographical error on line 246 - " we just map port 80 on the host to port 80 in the container" should be " we just map port 4000 on the host to port 80 in the container"
In the docker-compose file, the ports sections maps host port 4000 to container port 80, so if we want to see our app in a browser we should check on port 4000.
Proxy settings titles was placed in the DNS misconfiguration part, and the DNS settings title was placed in the proxy configuration part. This changes moves the places of the titles so that they both present the section they intend to.
The host port was set to 80, which was both inconsistent with the previous tutorial and also causing issues when following the tutorial on Windows.
For reference, here is the error when attempting to run a container on port 80:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint focused_euler (079893ea98df78bf7043f86072263317be106cbb7f4a3fcde23c2ef19ad39a01): Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error Permission denied.

Following the steps above I spent several hours trying to "Troubleshoot slow Docker swarm performance" as each web server in my stack was taking 'forever' to respond to HTTP requests, but worked just fine when invoked directly. I noticed it was taking almost exactly 30 seconds every time, and when finishing the turorial (thus deploying Redis) I realized that the python apps were waiting for some kind of Redis timeout. After deploying with a working Redis service responses were quick as before.
As somebody new to Docker it would have been good to know that the web app itself (timing out for Redis) was causing the delay not the host system or docker configuration.
This change will make sure request gets completed quickly. Without these it takes more than a minute for request to finish. This is especially important for beginners because they might not understand why request is taking so much time. Adding these parameters request completes quickly.
