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}}"
}
