Docker Remote API是一个取代远程命令行界面（rcli）的REST API。本文中，我们将使用命令行工具cURL来处理url相关操作。cURL可以发送请求、获取以及发送数据、检索信息。

本文档能够完成，主要借助于以下文档：

docker api 官方文档
dockerone组织翻译文档

1.容器相关

1.1 列出所有容器

GET /containers/json

URL:

/containers/json

查询参数:

all：获取所有容器信息，默认为false，仅显示正在运行的容器
limit：返回最近创建的容器的数量，包括未运行的容器。例如：limit=5 ，则返回5个最近创建的5个容器信息
size：将容器的大小作为字段SizeRw和SizeRootFs返回，默认为false
filters：过滤器处理容器列表，编码为JSON (map[string][]string)。例如，{“status”: [" stopped "]}将只返回暂停的容器

请求示例:

获取正在运行中的容器列表

curl http://127.0.0.1:5678/containers/json

查询全部的容器（包含不是正在运行的容器）

curl http://127.0.0.1:5678/containers/json?all=1

响应结果:

[root@localhost ~]# curl http://10.20.29.21:6666/containers/json?all=true
[{"Id":"15ffc3340941281cd6f515c1d34d15ee0cea3ee70cd1a0e34e39f94fcf06c98b","Names":["/shipyard-swarm-agent"],"Image":"docker.io/swarm:latest","ImageID":"sha256:ff454b4a0e84e50c50e3df457ad44b80f1a67ec6ec75cff5117dd5dc46bf4965","Command":"/swarm join --addr 10.20.29.21:6666 token://a997b11fdba7ede2551f9f8a17483bee","Created":1554858486,"Ports":[{"PrivatePort":2375,"Type":"tcp"}],"Labels":{},"State":"running","Status":"Up About an hour","HostConfig":{"NetworkMode":"default"},"NetworkSettings":{"Networks":{"bridge":{"IPAMConfig":null,"Links":null,"Aliases":null,"NetworkID":"74227783d8af05a30ae0d8817d984e815144387c1b1e4b7c6b9b10915579b61e","EndpointID":"9f85ced521dd4d081954de20af5350672fa08de18882614005d10ad2b94ff8b9","Gateway":"172.17.0.1","IPAddress":"172.17.0.4","IPPrefixLen":16,"IPv6Gateway":"","GlobalIPv6Address":"","GlobalIPv6PrefixLen":0,"MacAddress":"02:42:ac:11:00:04","DriverOpts":null}}},"Mounts":[{"Type":"volume","Name":"534f08f77e48bbc588756c5c1113807a3a0cbe8c6e073fb781fe6fd04a1d0d1c","Source":"","Destination":"/.swarm","Driver":"local","Mode":"","RW":true,"Propagation":""}]}
......

注：可通过python -mjson.tool可以将JSON数据格式化显示

成功后返回的参数：

ID：这个容器的ID
Names：这个容器的名称
Image：创建此容器时使用的镜像的名称
ImageID：：创建此容器时使用的镜像的ID
Command：启动容器时运行的命令
Created：容器创建时间

以上api各种使用方法灵感来源于：

hostconfig.json文件

文件路径：/var/lib/docker/containers/容器ID/hostconfig.json

[root@localhost 35a2f9491f6ad3d43a8e7c8b62acec1ccc82e90db844988b5a3c5f2ac630da5c]# cat hostconfig.json
{"Binds":["/etc/localtime:/etc/localtime","/etc/timezone:/etc/timezone","/mnt/public/mysql/data:/var/lib/mysql","/mnt/public/mysql/my.cnf:/etc/mysql/my.cnf"],"ContainerIDFile":"","LogConfig":{"Type":"json-file","Config":{}},"NetworkMode":"default","PortBindings":{"3306/tcp":[{"HostIp":"","HostPort":"13306"}]},"RestartPolicy":{"Name":"unless-stopped","MaximumRetryCount":0},"AutoRemove":false,"VolumeDriver":"","VolumesFrom":null,"CapAdd":null,"CapDrop":null,"Dns":[],"DnsOptions":[],"DnsSearch":[],"ExtraHosts":null,"GroupAdd":null,"IpcMode":"shareable","Cgroup":"","Links":null,"OomScoreAdj":0,"PidMode":"","Privileged":false,"PublishAllPorts":false,"ReadonlyRootfs":false,"SecurityOpt":null,"UTSMode":"","UsernsMode":"","ShmSize":67108864,"Runtime":"runc","ConsoleSize":[0,0],"Isolation":"","CpuShares":0,"Memory":0,"NanoCpus":0,"CgroupParent":"","BlkioWeight":0,"BlkioWeightDevice":[],"BlkioDeviceReadBps":null,"BlkioDeviceWriteBps":null,"BlkioDeviceReadIOps":null,"BlkioDeviceWriteIOps":null,"CpuPeriod":0,"CpuQuota":0,"CpuRealtimePeriod":0,"CpuRealtimeRuntime":0,"CpusetCpus":"","CpusetMems":"","Devices":[],"DeviceCgroupRules":null,"DiskQuota":0,"KernelMemory":0,"MemoryReservation":0,"MemorySwap":0,"MemorySwappiness":null,"OomKillDisable":false,"PidsLimit":0,"Ulimits":null,"CpuCount":0,"CpuPercent":0,"IOMaximumIOps":0,"IOMaximumBandwidth":0,"MaskedPaths":["/proc/asound","/proc/acpi","/proc/kcore","/proc/keys","/proc/latency_stats","/proc/timer_list","/proc/timer_stats","/proc/sched_debug","/proc/scsi","/sys/firmware"],"ReadonlyPaths":["/proc/bus","/proc/fs","/proc/irq","/proc/sys","/proc/sysrq-trigger"]}

注意：此时容器为Created（创建）状态，还需要启动容器

[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS                         PORTS                    NAMES

响应状态码解释

1.14 根据资源使用情况获取容器统计信息

此api用来显示容器使用的系统资源，下面是输出的主要内容：

[CONTAINER]：以短格式显示容器的 ID。
[CPU %]：CPU 的使用情况。
[MEM USAGE / LIMIT]：当前使用的内存和最大可以使用的内存。
[MEM %]：以百分比的形式显示内存使用情况。
[NET I/O]：网络 I/O 数据。
[BLOCK I/O]：磁盘 I/O 数据。
[PIDS]：PID 号。

GET /containers/{id}/stats

URL:

/containers/{id}/stats

路径参数:

ID：容器的ID或名称

查询参数:

stream：流输出，如果为false，则统计信息将输出一次，然后将断开连接。默认为true

默认情况下，只返回当前的状态，但可以每隔 1 秒钟刷新一次输出的内容，如果不想持续的监控容器使用资源的情况可以通过stream=false 参数只输出当前的状态。

请求示例:

curl http://10.20.29.21:2375/containers/545a4863e32f/stats?stream=false
