Right now, the quiet (-q, --quiet) flag ignores the output
generated from within the container.
However, it ought to be quiet in a way that all kind
of diagnostic output should be ignored, unless the build
process fails.
This patch makes the quiet flag behave in the following way:
1. If the build process succeeds, stdout contains the image ID
and stderr is empty.
2. If the build process fails, stdout is empty and stderr
has the error message and the diagnostic output of that process.
If the quiet flag is not set, then everything goes to stdout
and error messages, if there are any, go to stderr.

Each plug-in operates as a separate service, and registers with Docker
through general (plug-ins API)
[https://blog.docker.com/2015/06/extending-docker-with-plugins/]. No
Docker daemon recompilation is required in order to add / remove an
authentication plug-in. Each plug-in is notified twice for each
operation: 1) before the operation is performed and, 2) before the
response is returned to the client. The plug-ins can modify the response
that is returned to the client.
The authorization depends on the authorization effort that takes place
in parallel [https://github.com/docker/docker/issues/13697].
This is the official issue of the authorization effort:
https://github.com/docker/docker/issues/14674
(Here)[https://github.com/rhatdan/docker-rbac] you can find an open
document that discusses a default RBAC plug-in for Docker.

Docker daemon uses kv-store as the host-discovery backend.
Discovery module tracks the liveness of a node through a simple
keepalive mechanism. The keepalive mechanism depends on every
node performing heartbeat by registering itself with the discovery
module (via KV-Store Put operation). And for every Put operation,
the discovery module in all other nodes will receive a Watch
notification. That keeps the node alive.
Any node that fails to register itself within the TTL timer is
considered dead and removed from the discovery database.
The default timer (heartbeat = 20 seconds & ttl = 60 seconds)
works fine for small clusters. But for large clusters, these
default timers are extremely aggressive and that causes high CPU
& most of the processing is spent managing the node discovery
and that impacts normal daemon operation.
Hence we need a way to make the discovery ttl and heartbeat
configurable. As the cluster size grows, the user can change
these timers to make sure the daemon scales.

Use `pkg/discovery` to provide nodes discovery between daemon instances.
The functionality is driven by two different command-line flags: the
experimental `--cluster-store` (previously `--kv-store`) and
`--cluster-advertise`. It can be used in two ways by interested
components:
1. Externally by calling the `/info` API and examining the cluster store
field. The `pkg/discovery` package can then be used to hit the same
endpoint and watch for appearing or disappearing nodes. That is the
method that will for example be used by Swarm.
2. Internally by using the `Daemon.discoveryWatcher` instance. That is
the method that will for example be used by libnetwork.

- The build-time variables are passed as environment-context for command(s)
run as part of the RUN primitve. These variables are not persisted in environment of
intermediate and final images when passed as context for RUN. The build environment
is prepended to the intermediate continer's command string for aiding cache lookups.
It also helps with build traceability. But this also makes the feature less secure from
point of view of passing build time secrets.
- The build-time variables also get used to expand the symbols used in certain
Dockerfile primitves like ADD, COPY, USER etc, without an explicit prior definiton using a
ENV primitive. These variables get persisted in the intermediate and final images
whenever they are expanded.
- The build-time variables are only expanded or passed to the RUN primtive if they
are defined in Dockerfile using the ARG primitive or belong to list of built-in variables.
HTTP_PROXY, HTTPS_PROXY, http_proxy, https_proxy, FTP_PROXY and NO_PROXY are built-in
variables that needn't be explicitly defined in Dockerfile to use this feature.

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.

The concern there is we can't differentiate whether user explicitly
asked for an invalid value of -1 or he did not specify anything.
I don't think this would be a problem, because:
- like all other default values like zero, we can't differentiate
user specify it or not, most of which, zeros are also invalid, so
default is default, we show these default values in help info,
so users would know if they set value as default, it'll be like
they set nothing.

it'll make the behave different from docker command and RESTapi.

DeviceMapper must be explicitly selected because the Docker binary might not be linked to the right devmapper library.
With this change, Docker fails fast if the driver detection finds the devicemapper directory but the driver is not the default option.
The option `override_udev_sync_check` doesn't make sense anymore, since the user must be explicit to select devicemapper, so it's being removed.
Docker fails to use devicemapper only if Docker has been built statically unless the option was explicit.

publishing and inter-container communication.
Usage of the userland proxy remains the default as hairpin NAT is
unsupported by older kernels.

This patch modifies the journald log driver to store the container ID in
a field named CONTAINER_ID, rather than (ab)using the MESSAGE_ID field.
Additionally, this adds the CONTAINER_ID_FULL field containing the
complete container ID and CONTAINER_NAME, containing the container name.
When using the journald log driver, this permits you to see log messages
from a particular container like this:
# journalctl CONTAINER_ID=a9238443e193
Example output from "journalctl -o verbose" includes the following:
CONTAINER_ID=27aae7361e67
CONTAINER_ID_FULL=27aae7361e67e2b4d3864280acd2b80e78daf8ec73786d8b68f3afeeaabbd4c4
CONTAINER_NAME=web

This PR does the following:
- migrated ~/.dockerfg to ~/.docker/config.json. The data is migrated
but the old file remains in case its needed
- moves the auth json in that fie into an "auth" property so we can add new
top-level properties w/o messing with the auth stuff
- adds support for an HttpHeaders property in ~/.docker/config.json
which adds these http headers to all msgs from the cli
In a follow-on PR I'll move the config file process out from under
"registry" since it not specific to that any more. I didn't do it here
because I wanted the diff to be smaller so people can make sure I didn't
break/miss any auth code during my edits.

This provides an override for forcing the daemon to still attempt
running the devicemapper driver even when udev sync is not supported.
Intended to be a very clear impairment for those choosing to use it. If
udev sync is false, there will still be an error in the daemon logs,
even when the override is in place. The docs have an explicit WARNING.
Including link to the docs for users that encounter this daemon error
during an upgrade.

This flag is passed to the daemon CLI. In my opinion, "Container's
logging driver" is not accurate and refers to 'one container'.
Also the `syslog` driver was missing from the list. Having the list
of all logging drivers won't scale here (should be <80 chars per line)
and we have `rotation` driver coming up in the pipeline as well (gh11485).

Add the capability to cancel the build by disconnecting the client.
This adds a `cancelled` channel which is used to signal that a build
should halt. The build is halted by sending a Kill signal and noticing
that the cancellation channel is closed.
This first pass implementation does not allow cancellation during a
pull, but that will come in a subsequent PR.
* Add documentation of cancellation to cli and API
* Protect job cancellation with sync.Once
* Add TestBuildCancelationKillsSleep
* Add test case for build cancellation of RUN statements.

Adds more documentation for labels and adds the label instruction to the

Also included is a document called "Labels - custom meta-data in Docker"
in the user-guide, this is still a work-in-progress I started to describe
the "namespaces" conventions, an example on storing structured data.
I ran a bit "out of steam" (writers block?) on that document, but kept
it in (for now), in case it still ends up useful.

Save "LABEL" field in Dockerfile into image content.
This will allow a user to save user data into an image, which
can later be retrieved using:
docker inspect IMAGEID
I have copied this from the "Comment" handling in docker images.
We want to be able to add Name/Value data to an image to describe the image,
and then be able to use other tools to look at this data, to be able to do
security checks based on this data.
We are thinking about adding version names,
Perhaps listing the content of the dockerfile.
Descriptions of where the code came from etc.
This LABEL field should also be allowed to be specified in the

This adds two more tables to the run reference documentation.
- the list of 'modes' for Network settings is now a table.
- the "note" for `--net="host"` was moved from the list to the detailed
description.
- the 'options' for "Runtime constraints on CPU and memory" are
now a table
- slightly re-worded the description for "memory" options, e.g.
"It is not allowed..." was rewriten to "The *container* is not allowed..."
- fix example in "Runtime privilege, Linux capabilities, and LXC configuration"
being indented twice
- slightly reduced indenting in some `usage` output to be better readable.
- fixes a typo `/ets/hosts` -> `/etc/hosts`

Cgroup resources are host dependent, they should be in hostConfig.
For backward compatibility, we just copy it to hostConfig, and leave it in
Config for now, so there is no regressions, but the right way to use this
throught json is to put it in HostConfig, like:
{
"Hostname": "",
...
"HostConfig": {
"CpuShares": 512,
"Memory": 314572800,
...
}
}
As we will add CpusetMems, CpusetCpus is definitely a better name, but some
users are already using Cpuset in their http APIs, we also make it compatible.
The main idea is keep using Cpuset in Config Struct, and make it has the same
value as CpusetCpus, but not always, some scenarios:
- Users use --cpuset in docker command, it can setup cpuset.cpus and can
get Cpuset field from docker inspect or other http API which will get
config info.
- Users use --cpuset-cpus in docker command, ditto.
- Users use Cpuset field in their http APIs, ditto.
- Users use CpusetCpus field in their http APIs, they won't get Cpuset field
in Config info, because by then, they should already know what happens
to Cpuset.

This change adds daemon's system time as RFC3339Nano to the `/info` endpoint

I will be using this to fix the clock skew between the remote test host and

and `--until` and the timestamps are not matching when daemon is not on the
