The image built from the Dockerfile is currently failing to run properly. This is likely due to a minor revision update to version 0.10. Error details are shown below.

Note that when I change the "BASE" line in the Dockerfile to "BASE node:latest", everything works as expected.

Error details follow: When I jump into the v0.10 container and manually run the command (/usr/local/bin/node /data/app/index.js), I see the following error displayed:

root@32c1645004f8:/data/app# /usr/local/bin/node /data/app/index.js

Oops, I was careless in the errata I just posted a minute ago, and would like to correct my mistake, but cannot edit it.

I meant to say the line in the Dockerfile I changed was "FROM node:0.10", which I had to change to "FROM node:latest" to get it to work.

Thanks

I did more digging, and found that the exact version the "FROM node:0.10" is using is "node:0.10.48". I found that by looking at "docker inspect <image>", and verified it by changed the line in Dockerfile to "FROM node:0.10.48" and seeing the sha for the image is exactly the same (0f9a0e09fbda) as when I used "FROM node:0.10" (see output below). BTW that sha also matches the output in your book, so not sure if it is only failing for me, but it shouldn't because hey, this is docker right? oh well I reported it, thanks for reading.

Typo, misspelled "tehcnical"

"In the wake of this emergence rises a wave of innovation that demonstrates Linux containers’ potential to dramatically change application delivery across a variety of computing environments and platforms while leveraging a spectrum of tehcnical skill sets."

This line is from Page 11 "Even during the time that that it took us to write this book"

Issue is there are TWO of "THAT" word repeating and I was able to get the 53 page preview download from infoQ website.

In the first paragraph of the "Containers Are Lightweight" section, the 4th sentence begins "One the other hand". That should be "On the other hand".

"It is possible to run Docker on some older releases, but stability
may be an significant issue."

Should be

"It is possible to run Docker on some older releases, but stability
may be a significant issue."

Note from the Author or Editor:

The first line misspells "pieces" as "peices"

Note from the Author or Editor:
This is already fixed.

On page 43 (page 65 of the PDF) the following sentence appears to contain too many instances of the word "the".

"You’ll also start to use the build the variables you defined"

Note from the Author or Editor:
should be "build variables"

The below output is not correct if you take into account the command used to create the container "df542767bc17" on pag 71.

root@df542767bc17:/#mount | grep session
/dev/sda9 on /session_data type ext4 (rw,relatime,data=ordered)

The command used to create the container "df542767bc17" is the below:
$ docker run --rm -ti --read-only=true -v /mnt/session_data:/data ubuntu:latest /bin/bash

Therefore, the correct command inside the container should be "mount | grep data" and not "mount | grep session" and the correct output should be:

/dev/sda9 on /data type ext4 (rw,relatime,data=ordered)

Note from the Author or Editor:
fixed in upcoming release.

"the same was as" should be "the same way as"

Note from the Author or Editor:

" ... system in essentially the same WAS as any other ..." Should be WAY : " ... system in essentially the same WAY as any other ..."

"dynamic named assigned" should be

"logs all the containers logs" should be
"logs all the containers' logs".

"but does require that you set up log rotation" would be better as
"but it does require that you set up log rotation".

I suspect that ". . . the Docker API provides a lot more information on the stats endpoint that is shown in the client" should end with "than is shown in the client."

Second last line at is "expore some of the tools ..." here the first word should be "explore" rather than "expore".

Misspelled Chapter 6 title.
"Exploring Dockert" should be "Exploring Docker"

If you need to switch to the LXC driver, you should make sure you can support the version Docker that works best with. Running something outside the tested path is likely to encounter issue

In the middle of sentence above,"Support the version Docker that works best with" should be changed to "Support the version that Docker works best with"

Note from the Author or Editor:
This whole sentence has been removed in recent updates to the book.
