This displays the low-level information on Docker object(s) (e.g. container, image, volume,network, node, service, or task) identified by name or ID. By default, this will render all results in a JSON array. If the container and image have the same name, this will return container JSON for unspecified type. If a format is specified, the given template will be executed for each result. # EXAMPLES Get information about an image when image name conflicts with the container name, e.g. both image and container are named rhel7: $ docker inspect --type=image rhel7 [ { "Id": "fe01a428b9d9de35d29531e9994157978e8c48fa693e1bf1d221dffbbb67b170", "Parent": "10acc31def5d6f249b548e01e8ffbaccfd61af0240c17315a7ad393d022c5ca2", .... } ] ## Getting information on a container To get information on a container use its ID or instance name: $ docker inspect d2cc496561d6 [{ "Id": "d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47", "Created": "2015-06-08T16:18:02.505155285Z", "Path": "bash", "Args": [], "State": { "Running": false, "Paused": false, "Restarting": false, "OOMKilled": false, "Dead": false, "Pid": 0, "ExitCode": 0, "Error": "", "StartedAt": "2015-06-08T16:18:03.643865954Z", "FinishedAt": "2015-06-08T16:57:06.448552862Z" }, "Image": "ded7cd95e059788f2586a51c275a4f151653779d6a7f4dad77c2bd34601d94e4", "NetworkSettings": { "Bridge": "", "SandboxID": "6b4851d1903e16dd6a567bd526553a86664361f31036eaaa2f8454d6f4611f6f", "HairpinMode": false, "LinkLocalIPv6Address": "", "LinkLocalIPv6PrefixLen": 0, "Ports": {}, "SandboxKey": "/var/run/docker/netns/6b4851d1903e", "SecondaryIPAddresses": null, "SecondaryIPv6Addresses": null, "EndpointID": "7587b82f0dada3656fda26588aee72630c6fab1536d36e394b2bfbcf898c971d", "Gateway": "172.17.0.1", "GlobalIPv6Address": "", "GlobalIPv6PrefixLen": 0, "IPAddress": "172.17.0.2", "IPPrefixLen": 16, "IPv6Gateway": "", "MacAddress": "02:42:ac:12:00:02", "Networks": { "bridge": { "NetworkID": "7ea29fc1412292a2d7bba362f9253545fecdfa8ce9a6e37dd10ba8bee7129812", "EndpointID": "7587b82f0dada3656fda26588aee72630c6fab1536d36e394b2bfbcf898c971d", "Gateway": "172.17.0.1", "IPAddress": "172.17.0.2", "IPPrefixLen": 16, "IPv6Gateway": "", "GlobalIPv6Address": "", "GlobalIPv6PrefixLen": 0, "MacAddress": "02:42:ac:12:00:02" } } }, "ResolvConfPath": "/var/lib/docker/containers/d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47/resolv.conf", "HostnamePath": "/var/lib/docker/containers/d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47/hostname", "HostsPath": "/var/lib/docker/containers/d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47/hosts", "LogPath": "/var/lib/docker/containers/d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47/d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47-json.log", "Name": "/adoring_wozniak", "RestartCount": 0, "Driver": "devicemapper", "MountLabel": "", "ProcessLabel": "", "Mounts": [ { "Source": "/data", "Destination": "/data", "Mode": "ro,Z", "RW": false "Propagation": "" } ], "AppArmorProfile": "", "ExecIDs": null, "HostConfig": { "Binds": null, "ContainerIDFile": "", "Memory": 0, "MemorySwap": 0, "CpuShares": 0, "CpuPeriod": 0, "CpusetCpus": "", "CpusetMems": "", "CpuQuota": 0, "BlkioWeight": 0, "OomKillDisable": false, "Privileged": false, "PortBindings": {}, "Links": null, "PublishAllPorts": false, "Dns": null, "DnsSearch": null, "DnsOptions": null, "ExtraHosts": null, "VolumesFrom": null, "Devices": [], "NetworkMode": "bridge", "IpcMode": "", "PidMode": "", "UTSMode": "", "CapAdd": null, "CapDrop": null, "RestartPolicy": { "Name": "no", "MaximumRetryCount": 0 }, "SecurityOpt": null, "ReadonlyRootfs": false, "Ulimits": null, "LogConfig": { "Type": "json-file", "Config": {} }, "CgroupParent": "" }, "GraphDriver": { "Name": "devicemapper", "Data": { "DeviceId": "5", "DeviceName": "docker-253:1-2763198-d2cc496561d6d520cbc0236b4ba88c362c446a7619992123f11c809cded25b47", "DeviceSize": "171798691840" } }, "Config": { "Hostname": "d2cc496561d6", "Domainname": "", "User": "", "AttachStdin": true, "AttachStdout": true, "AttachStderr": true, "ExposedPorts": null, "Tty": true, "OpenStdin": true, "StdinOnce": true, "Env": null, "Cmd": [ "bash" ], "Image": "fedora", "Volumes": null, "VolumeDriver": "", "WorkingDir": "", "Entrypoint": null, "NetworkDisabled": false, "MacAddress": "", "OnBuild": null, "Labels": {}, "Memory": 0, "MemorySwap": 0, "CpuShares": 0, "Cpuset": "", "StopSignal": "SIGTERM" } } ] ## Getting the IP address of a container instance To get the IP address of a container use: $ docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' d2cc496561d6 172.17.0.2 ## Listing all port bindings One can loop over arrays and maps in the results to produce simple text output: $ docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} \ {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' d2cc496561d6 80/tcp -> 80 You can get more information about how to write a Go template from: https://golang.org/pkg/text/template/. ## Getting size information on a container $ docker inspect -s d2cc496561d6 [ { ....
