This patch adds a `--no-trunc` option to `docker container stats`;
With this patch applied, the default output is:

stats
Usage: docker stats [OPTIONS] [CONTAINER...]
Display a live stream of container(s) resource usage statistics
Options:
-a, --all Show all containers (default shows just running)
--format string Pretty-print images using a Go template
--help Print usage
--no-stream Disable streaming stats and only pull the first result
--no-trunc Don't truncate output
Description
The docker stats command returns a live data stream for running containers. To limit data to one or more specific containers, specify a list of container names or ids separated by a space. You can specify a stopped container but stopped containers do not return any data.
If you want more detailed information about a container's resource usage, use the /containers/(id)/stats API endpoint.
Examples
Running docker stats on all running containers against a Linux daemon.

Formatting
The formatting option (--format) pretty prints container output
using a Go template.
Valid placeholders for the Go template are listed below:
| Placeholder | Description |
|---|---|
.Container |
Container name or ID (user input) |
.Name |
Container name |
.ID |
Container ID |
.CPUPerc |
CPU percentage |
.MemUsage |
Memory usage |
.NetIO |
Network IO |
.BlockIO |
Block IO |
.MemPerc |
Memory percentage (Not available on Windows) |
.PIDs |
Number of PIDs (Not available on Windows) |
When using the --format option, the stats command either
outputs the data exactly as the template declares or, when using the
table directive, includes column headers as well.
The following example uses a template without headers and outputs the
Container and CPUPerc entries separated by a colon for all images:
$ docker stats --format "{{.Container}}: {{.CPUPerc}}"
09d3bb5b1604: 6.61%
9db7aa4d986d: 9.19%
3f214c61ad1d: 0.00%
To list all containers statistics with their name, CPU percentage and memory usage in a table format you can use:
$ docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"
CONTAINER CPU % PRIV WORKING SET
1285939c1fd3 0.07% 796 KiB / 64 MiB
9c76f7834ae2 0.07% 2.746 MiB / 64 MiB
d1ea048f04e4 0.03% 4.583 MiB / 64 MiB
The default format is as follows:
On Linux:
"table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}\t{{.PIDs}}"
On Windows:
"table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}\t{{.BlockIO}}"
Note
: On Docker 17.09 and older, the
{{.Container}}column was used, in stead of{{.ID}}\t{{.Name}}.
