The IndexServerAddress field was as part of the initial Windows implementation
of the engine. For legal reasons, Microsoft Windows (and thus Docker images
based on Windows) were not allowed to be distributed through non-Microsoft
infrastructure. As a temporary solution, a dedicated "registry-win-tp3.docker.io"
registry was created to serve Windows images.
Currently, this field always shows "https://index.docker.io/v1/", which is
confusing, because that address is not used for the registry (only for
authentication and "v1" search).
docker info
...
Registry: https://index.docker.io/v1/
Starting with b4ca1c7368, this field is also
no longer used during authentication, and a3d56e7d06
removed the (deprecated) ElectAuthServer() which was previously used to
query it.
Given that there's currently no practical use for this information, and
it only adds "noise" (and confusion), this patch removes it from the default
output.
For now, the field is (still) available for those that want to use it;
docker info --format '{{.IndexServerAddress}}'
https://index.docker.io/v1/
But it won't be printed by default.

No need to mention that the env-var may be removed at that point to keep

Support for this environment variable was removed in docker 23.0 in
1240f8b41d
From that patch:
> All regular, non-EOL Linux distros now come with more recent kernels
> out of the box. There may still be users trying to run on kernel 3.10
> or older (some embedded systems, e.g.), but those should be a rare
> exception, which we don't have to take into account.

> This patch removes the kernel version check on Linux, and the corresponding
> DOCKER_NOWARN_KERNEL_VERSION environment that was there to skip this
> check.

This patch adds additional information to the Client section of the output.
We were already outputting versions of CLI Plugins, and the Server, but not
for the Client.
Adding this information can help with bug-reports where the reporter only
provided the `docker info` output, or (e.g.) only `docker --version`. The
platform name helps identify what kind of builds the user has installed
(e.g. docker's docker-ce packages have "Docker Engine - Community" set
for this), although we should consider including "packager" information
as a more formalized field for this information.

Current versions of the docs generator take this into account, but on
the 20.10 branch, the trailing whitespace can make the YAML generator
switch to use "compact" formatting, which is hard to read, and hard
to review diffs when updating.

I think the cli code block misses a backslash to brevent line break when copy/pasting it to a terminal.
I doubt that this is intentional, if it is, feel free to reject the pr.

Use /bin/sh in the examples, as it's more likely to be present in a
container than bash (some users got confused by this, so using plain
"sh" in the examples could lead to less confusion).
Also added some extra wording around defaults, and how they're inherited
by the exec'd process.
It's definitely not "perfect" yet (lots to do in this document to improve
it), but it's a start :)

Update the example output to not use deprecated storage drivers or
Windows versions.
Also removes the section about `--debug`, because the `docker info` output
depends on the _daemon_ (not the client) to have debug mode enabled.

Some touch-ups in the attach reference and man-page;
- remove uses of old images (ubuntu 14.04)
- adds some more wording about `-i` and `-t` to use the detach sequence.
- use `--filter` instead of `grep` to list the container, to make the
example more portable.

This example was mounting `/dev/zero` as `/dev/nulo` inside the container.
The `nulo` name was intended to be a "made up / custom" name, but various
readers thought it to be a typo for `/dev/null`.
This patch updates the example to use `/dev/foobar` as name, which should
make it more clear that it's a custom name.

Commit 955c1f881a
(v17.12.0) replaced detection of support for multiple lowerdirs (as required by
overlay2) to not depend on the kernel version. The `overlay2.override_kernel_check`
was still used to print a warning that older kernel versions may not have full
support.
After this, e226aea280
(v20.10, but backported to v19.03.7) removed uses of the option altogether.
