Entire section

The description for Docker on Windows refers to the deprecated Boot2Docker installer. Docker client, since 1.6, has been native to Windows. While Docker Machine using Hyper-V (or Virtualbox) is the recommended way of starting a boot2docker VM on the local machine. Updated install instructions are at http://docs.docker.com/installation/windows/

Note from the Author or Editor:
Hi Ross, I struggled to get docker-machine working with Hyper-V. There are some open bugs about it on github. At least for Windows 8.1 it was buggy. So I opted not to cover the docker-machine hyper-v driver. I covered the Docker toolbox in a different recipes about OS X and mentioned this is the recommended way for Windows as well. The toolbox was released ~2 weeks ago with Docker 1.8. Boot2docker still works even though it is not the recommended install. As you know the docker toolbox still uses the boot2docker VM running in virtual box. I will see how I can make things clearer and cover toolbox for Windows. Thanks much for submitting an errata, -Sebastien

Second paragraph

In the Discussion section of "Publishing your image to Docker hub". Typo: "This recipes" should be "This recipe". In fact, the sentence might be better reworded as "This recipe introduced two new docker CLI commands...".

Note from the Author or Editor:
Thanks for the errata, this is now corrected. Be assured that O'Reilly does a thorough spell check, grammar review etc before publication. Cheers, -sebastien

The text reads "And if you want to add a tag manuall send...". "manuall" should be "manually".

Paragraph below Figure 2.1

The text says: "If you want to have private repistories, you will need to pay a subscription." (Side note: repositories is spelt incorrectly in the above sentence) However, the Docker Hub documentation at https://docs.docker.com/docker-hub/repos/#private-repositories says: "You get one private repository for free with your Docker Hub account" I've created a free account and I was able to create one private repository.

Note from the Author or Editor:
Good catch, thanks. Corrected and will be available in next update.

You are correct, the mistake is in the printed copy. It has been fixed in the ebook, but since there has not been an update to the printed copy, it is still there sadly. Thanks for reporting the issue and apologies for the error,

Section 'See also', first bullet line

The line: • Understanding the ONBUILD directive links to the url http://www.eikonomega.com/dockerfile-understand-onbuild/ which is a suspended ghost account hence getting redirected to https://ghost.org/suspended/

Note from the Author or Editor:
Thanks for catching this, you are correct. The URL in questioned is not available anymore, I just decided to remove the reference in the *See also* section.

2nd code block

In the 1st line of the 2nd code block from page 72 there's a typo on the command line: Originally it's: $ docker build -t flask Must have a final dot $ docker build -t flask . In the same page in the 3rd code block there's another mistake, the line code is: $ curl http://172.17.0.2:5000/ And must be: $ curl http://172.17.0.2:5000/hi

First line on this page

I am currently using docker version 1.9.1 when I type the following: docker service ls I get the following: docker: 'service' is not a docker command. See 'docker --help'. It seems like you are using 1.9.0-dev in that example. Not sure if that was a proper command in 1.9.0 and not in 1.9.1

Note from the Author or Editor:
Correct, I need to update it.

Third paragraph

The overlay filesystem is available in the Linux kernel starting with 3.18. Therefore to switch storage backends, you first need to upgrade (http://bit.ly/linux-318) the kernel of your machine to 3.8 and restart. Note: In the above paragraph, 3.8 should be 3.18 - This is a typo

Note from the Author or Editor:
Thank you for catching this. note: "Corrected typo in kernel version in recipe 4.12"

Warning or Caution section.

You clearly mention that the AUFS storage backend is available for 3.13-3.16 kernels, especially on Ubuntu systems. Overlay is now in the upstream kernel starting with 3.18, and AUFS is not available. Consider switching to Overlay. ----- I am clear about this here. But in the Docker web site, they recommend using the AUFS storage driver only. Is there any reason for this. I have been using devicemapper on my kernel version 3.14.58 without any issues. I am assuming that should be fine at least for the proof of concept purposes. Am I correct in making this assumption? Thank you.

Note from the Author or Editor:
Hi, you are correct you can use device mapper for proof of concept. It works. However the latest installation procedures from docker use aufs by default and device mapper is not recommended for production. If you start lots of containers, delete them etc, you might start to see some issues which are inherent to device mapper. So the bottom line is that Docker now recommends AUFS, and that's what you get by default from https://get.docker.com/ . However in newer kernels 3.18+ AUFS is not there anymore and overlayFS is the default. It seems to gain traction and gives better performance. Hence, you can see a future where OverlayFS may become the recommended storage driver, that's why I recommended using it.

"“Discussion on etcd is currently outside the scope of this cookbook. CoreOS provides a convenience etcd based discovery service to help with bootstrapping your CoreOS cluster. This is used in this Vagrant setup. This is not recommended in production.” Excerpt From: Sébastien Goasguen. “Docker Cookbook.” iBooks. It would be helpful to explain why this isn't recommended.

Note from the Author or Editor:
I will clarify the statement, and mention that the discovery service might be unresponsive without notice.
