in swarm.
Also, fix some CLI command confusions:
1. If the --external-ca flag is provided, require a --ca-cert flag as well, otherwise
the external CA is set but the CA certificate is actually rotated to an internal
cert
2. If a --ca-cert flag is provided, require a --ca-key or --external-ca flag be
provided as well, otherwise either the server will say that the request is
invalid, or if there was previously an external CA corresponding to the cert, it
will succeed. While that works, it's better to require the user to explicitly
set all the parameters of the new desired root CA.
This also changes the `swarm update` function to set the external CA's CACert field,
which while not strictly necessary, makes the CA list more explicit.

in future version — this should make be easier to remove it.
- Validate the `stack` name in all cases (i.e. whatever the

Removing a host by `<host>:<ip>` should only remove occurences of the host with
a matching IP-address, instead of removing all entries for that host.
In addition, combining `--host-rm` and `--host-add` for the same host should
result in the new host being added.
This patch fixes the way the diff is calculated to allow combining
removing/adding, and to support entries having both a canonical, and aliases.
Aliases cannot be added by the CLI, but are supported in the Service spec, thus
should be taken into account:
Entries can be removed by either a specific `<host-name>:<ip-address>`
mapping, or by `<host>` alone:
- If both IP-address and host-name is provided, only remove the hostname
from entries that match the given IP-address.
- If only a host-name is provided, remove the hostname from any entry it
is part of (either as _canonical_ host-name, or as _alias_).
- If, after removing the host-name from an entry, no host-names remain in
the entry, the entry itself should be removed.
For example, the list of host-entries before processing could look like this:
hosts = &[]string{
"127.0.0.2 host3 host1 host2 host4",
"127.0.0.1 host1 host4",
"127.0.0.3 host1",
"127.0.0.1 host1",
}
Removing `host1` removes every occurrence:
hosts = &[]string{
"127.0.0.2 host3 host2 host4",
"127.0.0.1 host4",
}
Whereas removing `host1:127.0.0.1` only remove the host if the IP-address matches:
hosts = &[]string{
"127.0.0.2 host3 host1 host2 host4",
"127.0.0.1 host4",
"127.0.0.3 host1",
}
Before this patch:

Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").
The workflow for creating a manifest list will be:
`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`
The annotate step is optional. Most architectures are fine by default.
There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.
To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).

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

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.

When deploying a stack from a compose file, the output did not show
that a secret or config was created. This patch adds messages for these.
Create a configuration file and compose file:
$ cat > config.yml <<EOF
hello: world

$ cat > secret.txt <<EOF
p@ssw0rd
EOF
$ cat > docker-compose.yml <<EOF

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
ID NAME MODE REPLICAS IMAGE PORTS
u1kwguv841qg foo replicated 1/1 nginx:alpine *:60->60/tcp,*:61->61/tcp,*:62->61/tcp,*:80->80/tcp,*:81->80/tcp,*:90->90/tcp,*:91->91/tcp,*:92->92/tcp,*:93->93/tcp,*:94->94/tcp,*:95->95/tcp,*:90->90/udp,*:91->91/udp,*:92->92/udp,*:93->93/udp,*:94->94/udp,*:95->95/udp,*:96->96/udp
After this patch is applied:
$ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
u1kwguv841qg foo replicated 1/1 nginx:alpine *:60-62->60-61/tcp,*:80-81->80/tcp,*:90-95->90-95/tcp,*:90-96->90-96/udp
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`

Running `docker service ps --quiet` should print the
full, non-truncated ID, even if the `--no-trunc` option
is not set.
This patch disables truncation if the `--quiet` flag
is set.

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;
$ docker service create nginx:alpine

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
- Change `Http Proxy` and `Https Proxy` to `HTTP Proxy` / `HTTPS Proxy`
