Extra hosts (`extra_hosts` in compose-file, or `--hosts` in services) adds
custom host/ip mappings to the container's `/etc/hosts`.
The current implementation used a `map[string]string{}` as intermediate
storage, and sorted the results alphabetically when converting to a service-spec.
As a result, duplicate hosts were removed, and order of host/ip mappings was not
preserved (in case the compose-file used a list instead of a map).
According to the **host.conf(5)** man page (http://man7.org/linux/man-pages/man5/host.conf.5.html)
multi Valid values are on and off. If set to on, the resolver
library will return all valid addresses for a host that
appears in the /etc/hosts file, instead of only the first.
This is off by default, as it may cause a substantial
performance loss at sites with large hosts files.
Multiple entries for a host are allowed, and even required for some situations,
for example, to add mappings for IPv4 and IPv6 addreses for a host, as illustrated
by the example hosts file in the **hosts(5)** man page (http://man7.org/linux/man-pages/man5/hosts.5.html):
# The following lines are desirable for IPv4 capable hosts
127.0.0.1 localhost
# 127.0.1.1 is often used for the FQDN of the machine
127.0.1.1 thishost.mydomain.org thishost
192.168.1.10 foo.mydomain.org foo
192.168.1.13 bar.mydomain.org bar
146.82.138.7 master.debian.org master
209.237.226.90 www.opensource.org
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
This patch changes the intermediate storage format to use a `[]string`, and only
sorts entries if the input format in the compose file is a mapping. If the input
format is a list, the original sort-order is preserved.

The `--host-add` flag adds a new `host:ip` mapping. Even though
adding an entry is idempotent (adding the same mapping multiple
times does not update the service's definition), it does not
_update_ an existing mapping with a new IP-address (multiple
IP-addresses can be defined for a host).
This patch removes the "or update" part from the flag's
description.

Port mappings in `docker service ls` are quite verbose, and occupy a lot of
space when ranges of ports are published.
This patch improves the output by reconstructing ranges of ports.
Given the following service;
$ docker service create \
-p 60-61:60-61 \
-p 62:61 \
-p 80:80 \
-p 81:80 \
-p 90-95:90-95 \
-p 90-92:90-92/udp \
-p 93-96:93-96/udp \
--name foo \
nginx:alpine
Before this patch is applied:
$ docker service ls

After this patch is applied:
$ docker service ls

Additional enhancements can still be made, and marked as TODO in this change;
- combine non-consecutive ports mapped to a single port (`80->80`, `81->80`,
`84->80`, `86->80`, `87->80`); to be printed as `*:80-81,84,86-87->80`.
- combine `tcp` and `udp` mappings if their port-mapping is the same;
print `*:80-81->80-81/tcp+udp` instead of `*:80-81->80-81/tcp, *:80-81->80-81/udp`

The `docker container stats` output has a column (`CONTAINER`), that shows either
the container _id_ or container _name_, depending on the arguments given.
For example, running `docker container stats foobar` shows:
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
foobar 0.00% 1.938MiB / 1.952GiB 0.10% 782B / 0B 4.11MB / 0B 2
Whereas `docker container stats 67b2525d8ad1` (`67b2525d8ad1` being the ID for
container `foobar`) shows:
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad1 0.00% 1.938MiB / 1.952GiB 0.10% 916B / 0B 4.11MB / 0B 2
This behavior is confusing.
This patch updates the default output format for `docker stats` to use separate
columns for container ID and container Name (similar to `docker container ls`).
With this patch applied, both commands show the same output:
$ docker container stats foobar
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad10bb236a49960e93c09993b0baabeef12c2d46cd5f4fbb6f4808c foobar 0.00% 1.938MiB / 1.952GiB 0.10% 1.25kB / 0B 4.11MB / 0B 2
$ docker container stats 67b2525d8ad1
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad10bb236a49960e93c09993b0baabeef12c2d46cd5f4fbb6f4808c foobar 0.00% 1.938MiB / 1.952GiB 0.10% 1.31kB / 0B 4.11MB / 0B 2
Users that want to use the old format can configure a custom format in the
cli configuration file (`~/.docker/config.json`);
on Linux:
{
"statsFormat" : "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}\t{{.PIDs}}"
}
on Windows:
{
"statsFormat" : "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}\t{{.BlockIO}}"

Commit 330a0035334871d92207b583c1c36d52a244753f added a `--detach=false` option
to various service-related commands, with the intent to make this the default in
a future version (17.09).
This patch changes the default to use "interactive" (non-detached), allowing
users to override this by setting the `--detach` option.
To prevent problems when connecting to older daemon versions (17.05 and below,
see commit db60f25561), the detach option is
ignored for those versions, and detach is always true.
Before this change, a warning was printed to announce the upcoming default:
$ docker service create nginx:alpine
saxiyn3pe559d753730zr0xer
Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
After this change, no warning is printed, but `--detach` is disabled;
$ docker service create nginx:alpine
y9jujwzozi0hwgj5yaadzliq6
overall progress: 1 out of 1 tasks
1/1: running [==================================================>]
verify: Service converged
Setting the `--detach` flag makes the cli use the pre-17.06 behavior:
$ docker service create --detach nginx:alpine
280hjnzy0wzje5o56gr22a46n
Running against a 17.03 daemon, without specifying the `--detach` flag;

Some mild refactoring of the docker info command;
- Use `fmt.Fprinln()` instead of `fmt.Fprintf()` where possible
- Rename `fprintfIfNotEmpty()` to `fprintlnNonEmpty()`, and removed
return variables, because they were not used. `fprintlnNonEmpty()`
now uses fmt.Fprintln()` instead of `fmt.Fprintf()`, because
formatting was not used.
- Use `fprintlnNonEmpty()` to get rid of some `if` statements
- Extract printing Swarm-related information to a `printSwarmInfo()` function

The validation functions to test for the number of passed arguments did not
pluralize `argument(s)`, and used `argument(s)` in all cases.
This patch adds a simple `pluralize()` helper to improve this.
Before this change, `argument(s)` was used in all cases:
$ docker container ls foobar
"docker container ls" accepts no argument(s).
$ docker network create one two
"docker network create" requires exactly 1 argument(s).
$ docker network connect
"docker network connect" requires exactly 2 argument(s).
$ docker volume create one two
"docker volume create" requires at most 1 argument(s).
After this change, `argument(s)` is properly singularized or plurarized:
$ docker container ls foobar
"docker container ls" accepts no arguments.
$ docker network create one two
"docker network create" requires exactly 1 argument.
$ docker network connect
"docker network connect" requires exactly 2 arguments.
$ docker volume create one two
"docker volume create" requires at most 1 argument.
Test cases were updated accordingly.

When re-deploying a stack without re-resolving the image digest,
the service's ContainerSpec was updated with the image-reference
as specified in the stack/compose file.
As a result, the image-digest that was resolved in a previous
deploy was overwritten, causing the service to be re-deployed.
This patch preserves the previously resolve image-digest
by copying it from the current service spec.
A unit test is also added to verify that the image information
in the service spec is not updated if QueryRegistry is disabled.

Some network environments may have NATs, proxies, or gateways which
kill idle connections. There are many Docker API operations which may
be idle for long periods of time (such as ContainerWait and ContainerAttach)
and may result in unexpected connection closures or hangs if TCP keepalives
are not used.
This patch updates the default HTTP transport used by the Docker client
package to enable TCP Keep-Alive with a keep-alive interval of 30 seconds.
It also sets a connect timeout of 30 seconds.

When running `docker stack rm <some stack>` against an older daemon,
a warning was printed for "configs" being ignored;
WARNING: ignoring "configs" (requires API version 1.30, but the Docker daemon API version is 1.26)
Given that an old daemon cannot _have_ configs, there should not be
a need to warn, or _attempt_ to remove these resources.
This patch removes the warning, and skips fetching (and removing)
configs.
A check if _secrets_ are supported by the daemon is also added,
given that this would result in an error when attempted against
an older (pre 1.13) daemon.
There is one situation where this could lead to secrets or
configs being left behind; if the client is connecting to a
daemon that _does_ support secrets, configs, but the API version
is overridden using `DOCKER_API_VERSION`, no warning is printed,
and secrets and configs are not attempted to be removed.
Given that `DOCKER_API_VERSION` is regarded a feature for
debugging / "power users", it should be ok to ignore this.
