Auto-creation of host-directories was marked deprecated in
Docker 1.9, but was decided to be too much of an backward-incompatible
change, so it was decided to keep the feature.

This allows a user to specify explicitly to enable
automatic copying of data from the container path to the volume path.
This does not change the default behavior of automatically copying, but
does allow a user to disable it at runtime.

All other options we have use `=` as separator, labels,
log configurations, graph configurations and so on.
We should be consistent and use `=` for the security
options too.

Docker creates a UTS namespace by default, even with --net=host, so it
is reasonable to let the user set the hostname. Note that --hostname is
forbidden if the user specifies --uts=host.

This makes it so when calling `docker run --rm`, or `docker rm -v`, only
volumes specified without a name, e.g. `docker run -v /foo` instead of
`docker run -v awesome:/foo` are removed.
Note that all volumes are named, some are named by the user, some get a
generated name. This is specifically about how the volume was specified
on `run`, assuming that if the user specified it with a name they expect
it to persist after the container is cleaned up.

The existing example didn't illustrate how to
install strace in the container. In addition,
the rhel7 image used is no longer public (and maintained)
so not a good image to use in the example.
This updates the example to use htop (strace is
not working without disabling apparmor for the container)

This fixes markdown formatting, and formatting of tables;
- Our markdown engine doesn't support spanning rows, so
re-wrapped table contents.
- Added a CSS-styles to prevent "code" blocks in tables
from wrapping
- The "logging drivers" table didn't have a header
- Aligned table borders in source code for better readability.
- Standardize on using `-it` in stead of -i -t or -ti
- Some markup issues
- Some minor textual fixups

- Optional "--shm-size=" was added to the sub-command(run, create,and build).
- The size of /dev/shm in the container can be changed
when container is made.
- Being able to specify is a numerical value that applies number,
b, k, m, and g.
- The default value is 64MB, when this option is not set.
- It deals with both native and lxc drivers.

The LXC driver was deprecated in Docker 1.8.
Following the deprecation rules, we can remove a deprecated feature

The purpose of this PR is for users to distinguish Docker errors from
contained command errors.
This PR modifies 'docker run' exit codes to follow the chroot standard
for exit codes.
Exit status:
125 if 'docker run' itself fails
126 if contained command cannot be invoked
127 if contained command cannot be found
the exit status otherwise

If a logdriver doesn't register a callback function to validate log
options, it won't be usable. Fix the journald driver by adding a dummy
validator.
Teach the client and the daemon's "logs" logic that the server can also
supply "logs" data via the "journald" driver. Update documentation and
tests that depend on error messages.
Add support for reading log data from the systemd journal to the
journald log driver. The internal logic uses a goroutine to scan the
journal for matching entries after any specified cutoff time, formats
the messages from those entries as JSONLog messages, and stuffs the
results down a pipe whose reading end we hand back to the caller.
If we are missing any of the 'linux', 'cgo', or 'journald' build tags,
however, we don't implement a reader, so the 'logs' endpoint will still
return an error.
Make the necessary changes to the build setup to ensure that support for
reading container logs from the systemd journal is built.
Rename the Jmap member of the journald logdriver's struct to "vars" to
make it non-public, and to make it easier to tell that it's just there
to hold additional variable values that we want journald to record along
with log data that we're sending to it.
In the client, don't assume that we know which logdrivers the server
implements, and remove the check that looks at the server. It's
redundant because the server already knows, and the check also makes
using older clients with newer servers (which may have new logdrivers in
them) unnecessarily hard.
When we try to "logs" and have to report that the container's logdriver
doesn't support reading, send the error message through the
might-be-a-multiplexer so that clients which are expecting multiplexed
data will be able to properly display the error, instead of tripping
over the data and printing a less helpful "Unrecognized input header"
error.
