The steps detailing the cycle of getting an application to production. Specifically step 7 states: "Loop over steps 5 and 6 n more times". Yet the diagram in Figure 2-1 loops from steps 4 - 6. Depending on the correct process either the step or the diagram should be updated to match each other.

In the first code block where a redis container is created

The book creates a container using `docker container create -p 6379:6379 redis:2.8`. However, the command's output indicates `redis:7.0` was downloaded.

In the second code block

The command `docker container ls -a --filter ancestor=redis:2.8` lists all containers that share a given image (redis:2.8). However, the output of the command shows `redis:7.0` instead.

In the first note

The note explains most docker commands will work using the full hash of the container (092c5dc850446324e…a37299d35fc67a042) or even just enough of the hash to make it unique. It finalizes the note saying that the command `docker container start 6b7` would have just worked fine. However, the command would not work as "6b7" is not found anywhere in the container's hash.

The text "Unlike stopping a container, where the processes are made aware that they are stopping via the SIGSTOP signal" should be "Unlike stopping a container, where the processes are made aware that they are stopping via the SIGTERM signal".

the first command `docker container run`

in the code, `g` means not specific

```
$ docker container run --rm --entrypoint htpasswd g \
-Bbn ${<username>} ${<password>} > htpasswd
```

maybe it should change to:

```
$ docker container run --rm --entrypoint htpasswd httpd:2.4 \
-Bbn ${<username>} ${<password>} > htpasswd
```

the command: docker container run --rm -d --name nginx-debug --rm nginx:latest

--rm option used twice in the command, should delete one

I filled in all fields in steps 1 & 2 (doesn't have "Organization Type" though), but I do not get the option "Continue as standalone" in step 3 which renders this whole chapter as unworkable?

193

When cloning the git repository, for the rocketchat-hubot-demo, from the book on page 193, the included 'docker-compose.yaml' file does not match the example shown here.

This 'docker-compose.yaml' file *does* however seem to match the 'docker-compose-default.yaml' file later referred to on page 207

Running the current supplied file ("default"), the zmachine and hubot bots appear in the application, after composing and running, however the bots do not function (running . as the alias for 'hubot' and z for 'zmachine' + commands does nothing).

Running the copy/pasted text from page 193, composing and running, seems to run the application but it prompts you with an administrator page, to create an administrator account, and is minus the bots (!)

Regardless, both yaml files do not seem to work, as expected/documented.

I am running this on Linux Mint 22 with Docker Compose version 2.32.4

Docker Swarm Mode section

Usage of the 'docker -H...' command, via Worker nodes, assumes OpenSSL, x509, and TLS configuration on users machines. This is an advanced topic and not all machines are configured in this manner.

When issuing this command, an unconfigured machine, will recieve "TLS handshake" errors as well as the "Is the docker daemon running?" error - vague enough to not realize it's actually a TLS issue.

For configuration details, see the official Docker documentation "Engine/Security/Protect-Access/" under the header "Use TLS (HTTPS) to protect the Docker daemon socket"

Using alternative sockets (such as unix://, tcp://, etc.) as per the Docker documentation also does not work.

Please update section with either a link to setting up this kind of configuration or provide examples that do not require this elaborate configuration to work.

Text "You can then restart the container after adding a single instance of the --env argument to the previous docker container run command:"

My understanding, thanks to the book, is that I am _not_ "restarting" this container by:

1. Stopping the running container, then
2. Issuing a fresh `docker container run` command.

I am, in fact, starting a _new_ container that has different properties to the one that I stopped.

Loving the book so far, thank you.

Page Layers Are Additive
After 1st paragraph in "Notes" section

using docker image build --squash . This will deleted files actually disappear and...

I think there is a word missing:
"This will make (?) deleted files..."

Note from the Author or Editor:
This already had a minor fix applied, but let's rework this sentence so that it reads like this:

This will cause all of the files that were deleted in the intermediate layers to actually disappear from the final image and can therefore recover a lot of wasted space, but it also means that the whole layer must be downloaded by every system that requires it, even when only a single line of source code was updated, so there are real trade-offs to using this approach.
