Update default output format for stats to include ID and Name 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}}" } Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

Fix panic of "docker stats --format {{.Name}} --all" This commit fixes panic when execute stats command: * use --format {{.Name}} with --all when there're exited containers. * use --format {{.Name}} while stating exited container. The root cause is when stating an exited container, the result from the api didn't contain the Name and ID field, which will make format process panic. Panic log is like this: ``` panic: runtime error: slice bounds out of range [recovered] panic: runtime error: slice bounds out of range goroutine 1 [running]: panic(0xb20f80, 0xc420014110) /usr/local/go/src/runtime/panic.go:500 +0x1a1 text/template.errRecover(0xc4201773e8) /usr/local/go/src/text/template/exec.go:140 +0x2ad panic(0xb20f80, 0xc420014110) /usr/local/go/src/runtime/panic.go:458 +0x243 github.com/docker/docker/cli/command/formatter.(*containerStatsContext).Name(0xc420430160, 0x0, 0x0) /go/src/github.com/docker/docker/cli/command/formatter/stats.go:148 +0x86 reflect.Value.call(0xb9a3a0, 0xc420430160, 0x2213, 0xbe3657, 0x4, 0x11bc9f8, 0x0, 0x0, 0x4d75b3, 0x1198940, ...) /usr/local/go/src/reflect/value.go:434 +0x5c8 reflect.Value.Call(0xb9a3a0, 0xc420430160, 0x2213, 0x11bc9f8, 0x0, 0x0, 0xc420424028, 0xb, 0xb) /usr/local/go/src/reflect/value.go:302 +0xa4 text/template.(*state).evalCall(0xc420177368, 0xb9a3a0, 0xc420430160, 0x16, 0xb9a3a0, 0xc420430160, 0x2213, 0x1178fa0, 0xc4203ea330, 0xc4203de283, ...) /usr/local/go/src/text/template/exec.go:658 +0x530 ``` Signed-off-by: Zhang Wei <zhangwei555@huawei.com>
