The reason is that in case a default value is decided by daemon,

Commit ed13c3abfb242905ec012e8255dc6f26dcf122f6 added flags
for Docker Content Trust. Depending on the `verify` boolean,
the message is "Skip image verification", or "Skip image signing".
"Signing" is intended for `docker push` / `docker plugin push`.
During the migration to Cobra, this boolean got flipped for
`docker push` (9640e3a4514f96a890310757a09fd77a3c70e931),
causing `docker push` to show the incorrect flag description.
This patch changes the flags to use the correct description
for `docker push`, and `docker plugin push`.
To prevent this confusion in future, the boolean argument
is removed, and a `AddTrustSigningFlags()` function is added.

This fix tries to address the issue raised in 29291 where
the output of `--replicas` in `service create/update`:
```
--replicas uint Number of tasks (default none)
```
is misleading. User might incorrectly assume the number of replicas
would be `0` (`none`) by default, while the actual default is `1`.
The issue comes from the fact that some of the default values are
from daemon and it is not possible for client to find out the default
value.
In this case, it might be better to just simply not displaying `(default none)`.
This fix returns "" for `Uint64Opt` so that `(default none)` is hidden.
In addition to `--replicas`, this fix also changes
`--restart-delay`, `--restart-max-attempts`, `--stop-grace-period`,
`--health-interval`, `--health-timeout`, and `--restart-window`
in a similiar fashion.

Previously the output string of the `DurationOpt` is `duration-ptr`
and `Uint64Opt` is `uint64-ptr`. While it is clear to developers,
for a normal user `-ptr` might not be very informative.
On the other hand, the default value of `DurationOpt` and `Uint64Opt`
has already been quite informative: `none`. That means if no flag
provided, the value will be treated as none.
(like a ptr with nil as the default)
For that reason this fix removes the `-ptr`.
Also, the output in the docs of `service create` has been quite
out-of-sync with the true output. So this fix updates the docs
to have the most up-to-date help output of `service create --help`.

Add the following options to "swarm init" and "swarm update":
- --max-snapshots: Retain this many old Raft snapshots in addition
to the latest one
- --snapshot-interval: Number of log entries between Raft snapshots
These options already existed in SwarmKit and the Docker API but were
never exposed in the CLI. I'm adding them here to fix this oversight.
--max-snapshots may be useful for debugging purposes and more
conservative users who want to store rolling backups of old versions of
the Raft state.
--snapshot-interval is most useful for performance tuning. The default
value of 10000 may not be ideal for some setups.
There is also a LogEntriesForSlowFollowers option that is not exposed. I
decided not to expose it along with these others because I don't think
it's generally useful (and I'm not sure what I would call the CLI flag).

Currently, there's no way to restart the tasks of a service without
making an actual change to the service. This leads to us giving awkward
workarounds as in
https://github.com/docker/docker.github.io/pull/178/files, where we tell
people to scale a service up and down to restore balance, or make
unnecessary changes to trigger a restart.
This change adds a --force option to "docker service update", which
forces the service to be updated even if no changes require that.
Since rolling update parameters are respected, the user can use
"docker service --force" to do a rolling restart. For example, the
following is supported:
docker service update --force --update-parallelism 2 \
--update-delay 5s myservice
Since the default value of --update-parallelism is 1, the default
behavior is to restart the service one task at a time.

This adds support for two enhancements to swarm service rolling updates:
- Failure thresholds: In Docker 1.12, a service update could be set up
to either pause or continue after a single failure occurs. This adds
an --update-max-failure-ratio flag that controls how many tasks need to
fail to update for the update as a whole to be considered a failure. A
counterpart flag, --update-monitor, controls how long to monitor each
task for a failure after starting it during the update.
- Rollback flag: service update --rollback reverts the service to its
previous version. If a service update encounters task failures, or
fails to function properly for some other reason, the user can roll back
the update.
SwarmKit also has the ability to roll back updates automatically after

This adds a small C binary for fighting zombies. It is mounted under
`/dev/init` and is prepended to the args specified by the user. You
enable it via a daemon flag, `dockerd --init`, as it is disable by
default for backwards compat.
You can also override the daemon option or specify this on a per
container basis with `docker run --init=true|false`.
You can test this by running a process like this as the pid 1 in a
container and see the extra zombie that appears in the container as it
is running.
```c
int main(int argc, char ** argv) {
pid_t pid = fork();

When xfs filesystem is being used on top of thin pool, xfs can get ENOSPC
errors from thin pool when thin pool is full. As of now xfs retries the
IO and keeps on retrying and does not give up. This can result in container
application being stuck for a very long time. In fact I have seen instances
of unkillable processes. So that means once thin pool is full and process
gets stuck, container can't be stopped/killed either and only option left
seems to be power recycle of the box.
In another instance, writer did not block but failed after a while. But
when I tried to exit/stop the container, unmounting xfs hanged and only
thing I could do was power cycle the machine.
Now upstream kernel has committed patches where it allows user space to
customize user space behavior in case of errors. One of the knobs is
max_retries, which specifies how many times an IO should be retried
when ENOSPC is encountered.
This patch sets provides a tunable knob (dm.xfs_nospace_max_retries) so
that user can specify value for max_retries and tune xfs behavior. If
one sets this value to 0, xfs will not retry IO when ENOSPC error is
encountered. It will instead give up and shutdown filesystem.
This knob can be useful if one is running into unkillable
processes/containers issue on top of xfs.

this change improves the instructions for

- print a message that a token was rotated

- add some extra white-space before / after

this change also does some refactoring of join-token;
- move flagname-constants together with other constants
- use variables for selected role ("worker" / "manager")
to prevent checking for them multiple times, and to
keep the "worker" / "manager" sting centralized
- add an extra blank line after "join-token" instructions

Rather than conflict with the unexposed task model, change the names of
the object-oriented task display to `docker <object> ps`. The command
works identically to `docker service tasks`. This change is superficial.
This provides a more sensical docker experience while not trampling on
the task model that may be introduced as a top-level command at a later
date.
The following is an example of the display using `docker service ps`
with a service named `condescending_cori`:
```
$ docker service ps condescending_cori

e2cd9vqb62qjk38lw65uoffd2 condescending_cori.1 condescending_cori alpine Running 13 minutes ago Running 6c6d232a5d0e

This changes the default behavior so that rolling updates will not
proceed once an updated task fails to start, or stops running during the
update. Users can use docker service inspect --pretty servicename to see
the update status, and if it pauses due to a failure, it will explain
that the update is paused, and show the task ID that caused it to pause.
It also shows the time since the update started.
A new --update-on-failure=(pause|continue) flag selects the
behavior. Pause means the update stops once a task fails, continue means
the old behavior of continuing the update anyway.
In the future this will be extended with additional behaviors like
automatic rollback, and flags controlling parameters like how many tasks
need to fail for the update to stop proceeding. This is a minimal
solution for 1.12.

Hostnames are not supported for now because libnetwork can't use them

Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com>
There are currently problems with "swarm init" and "swarm join" when an
explicit --listen-addr flag is not provided. swarmkit defaults to
finding the IP address associated with the default route, and in cloud
setups this is often the wrong choice.
Introduce a notion of "advertised address", with the client flag
--advertise-addr, and the daemon flag --swarm-default-advertise-addr to
provide a default. The default listening address is now 0.0.0.0, but a
valid advertised address must be detected or specified.
If no explicit advertised address is specified, error out if there is
more than one usable candidate IP address on the system. This requires a
user to explicitly choose instead of letting swarmkit make the wrong
choice. For the purposes of this autodetection, we ignore certain
interfaces that are unlikely to be relevant (currently docker*).
The user is also required to choose a listen address on swarm init if
they specify an explicit advertise address that is a hostname or an IP
address that's not local to the system. This is a requirement for
overlay networking.
Also support specifying interface names to --listen-addr,
--advertise-addr, and the daemon flag --swarm-default-advertise-addr.
This will fail if the interface has multiple IP addresses (unless it has
a single IPv4 address and a single IPv6 address - then we resolve the
tie in favor of IPv4).
This change also exposes the node's externally-reachable address in
docker info, as requested by #24017.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.
