"docker node ps" behaves strangely outside swarm mode:
$ docker node ps
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
Error: No such node:
It should explain that the node is not a swarm manager.
The reason this happens is that the argument to "docker node ps" defaults
to "self". The first thing the command does is try to resolve "self" to
a node ID using the /info endpoint. If there is no node ID, it tries to
use the empty string as an ID, and tries to GET /nodes/, which is not a
valid endpoint.
Change the command to check if the node ID is present in the /info
response. If it isn't, a swarm API endpoint can supply a useful error
message.
Also, avoid printing the column headers if the only following text is an
error.

This type is only used by CLI code. It duplicates SecretReference in the
types/swarm package. Change the CLI code to use that type instead.

when i was using:
docker search --automated -s 3 nginx
told me:
Flag --automated has been deprecated, use --filter=automated=true instead
Flag --stars has been deprecated, use --filter=stars=3 instead
and when i use:
docker search --filter=automated=true --filter=stars=3 nginx
told me:
Error response from daemon: Invalid filter 'automated'
and i found out that the correct command should be:
docker search --filter=is-automated=true --filter=stars=3 nginx

For an environment variable defined in the yaml without value,
the value needs to be propagated from the client, as in Docker Compose.

This change adds the ability to do --tail and --since on docker service
logs. It wires up the API endpoints to each other and fixes some older
bugs. It adds integration tests for these new features.

In https://github.com/torvalds/linux/commit/5ca3726 (released in v4.7-rc1) the
content of the `cpuacct.usage_percpu` file in sysfs was changed to include both
online and offline cpus. This broke the arithmetic in the stats helpers used by
`docker stats`, since it was using the length of the PerCPUUsage array as a
proxy for the number of online CPUs.
Add current number of online CPUs to types.StatsJSON and use it in the
calculation.
Keep a fallback to `len(v.CPUStats.CPUUsage.PercpuUsage)` so this code
continues to work when talking to an older daemon. An old client talking to a
new daemon will ignore the new field and behave as before.
Fixes#28941.

- Align output. Previously, output would end up unaligned because of
longer task names (e.g. web.1 vs web.10)
- Truncate task IDs and add a --no-trunc option
- Added a --no-ids option to remove IDs altogether
- Got rid of the generic ID Resolver as we need more customization.

Server-side rollback can take advantage of the rollback-specific update

Without this fix the error the client might see is:
target is unknown
which wasn't helpful to me when I saw this today. With this fix I
now see:
MediaType is unknown: 'text/html'
which helped me track down the issue to the registry I was talking to.

The overlay(2) drivers were moved up in the list of storage drivers,
and are known to have problems if the backing filesystem does not
support d_type.
Commit 2e20e63da2a8a0ffbbb3f2146f87559e17f43046 added a warning,
which is logged in the daemon logs, however, many users do not
check those logs, and may overlook this warning.
This patch adds the same warning to the output of `docker info`
so that the warning is more easily found.
In addition, the output of warnings printed by `docker info` is
optimized, by;
- moving all warnings to the _end_ of the output, instead of
mixing them with the regular output
- wrapping the storage-driver warnings, so that they are more
easily readable
Example output with this patch applied

This fix tries to address the issue raised in 25696 where
it was not possible to specify `--stop-signal` for `docker service create`
and `docker service update`, in order to use special signal to stop
the container.
This fix adds `--stop-signal` and update the `StopSignal` in `Config`
through `service create` and `service update`.
Related docs has been updated.
Integration test has been added.
This fix fixes 25696.

This fix ignore some functions in the Go template when header is
redendered, so that `--format "{{truncate .ID 1}}"` will still
be able to redener the header correctly.

This fix is an attempt to address
https://github.com/docker/docker/pull/28213#issuecomment-273840405
Currently when specify table format with table `--format "table {{.ID}}..."`,
the delimiter in the header section of the table is always `"\t"`.
That is actually different from the content of the table as the delimiter
could be anything (or even contatenated with `.`, for example):
```
$ docker service ps web --format 'table {{.Name}}.{{.ID}}' --no-trunc
NAME ID
web.1.inyhxhvjcijl0hdbu8lgrwwh7
\_ web.1.p9m4kx2srjqmfms4igam0uqlb
```
This fix is an attampt to address the skewness of the table when delimiter
is not `"\t"`.
The basic idea is that, when header consists of `table` key, the header section
will be redendered the same way as content section. A map mapping each
placeholder name to the HEADER entry name is used for the context of the header.
Unit tests have been updated and added to cover the changes.
This fix is related to #28313.
