Docker——常用命令（四）

本文只列举了几个常用的命令，其他命令可使用--help查看或在网上自行查阅

一、查看当前版本

命令：docker version   或者   docker -v

[root@localhost ~]# docker versionClient version: 1.7.1Client API version: 1.19Go version (client): go1.4.2Git commit (client): 786b29d/1.7.1OS/Arch (client): linux/amd64Server version: 1.7.1Server API version: 1.19Go version (server): go1.4.2Git commit (server): 786b29d/1.7.1OS/Arch (server): linux/amd64[root@localhost ~]# docker -vDocker version 1.7.1, build 786b29d/1.7.1[root@localhost ~]# 

二、查看当前所有docker镜像

命令：docker images

[root@localhost ~]# docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE[root@localhost ~]#

三、拉取远程docker镜像

网易蜂巢docker镜像库地址：https://c.163.com/hub#/m/home/

命令：docker pull [OPTIONS] NAME[:TAG]

e.g.. docker pull hub.c.163.com/wangjiaen/centos6.9:ssh     （从网易蜂巢拉取一个contos6.9的镜像）

[root@localhost ~]# docker pull hub.c.163.com/wangjiaen/centos6.9:sshssh: Pulling from hub.c.163.com/wangjiaen/centos6.9ebe688773310: Pull complete 7d9a6cbcf4ff: Pull complete 48a89683e055: Pull complete 166c7265ea0d: Pull complete 5caf8ed79df7: Already exists Digest: sha256:0d07d3e54a974c483c83dd64194718968b962e74c805833633fd12a5d0f31774Status: Downloaded newer image for hub.c.163.com/wangjiaen/centos6.9:ssh[root@localhost ~]# 

四、Docker的帮助命令

命令：docker COMMAND --help

e.g..  docker --help  、 docker run --help （列出docker的参数命令帮助、列出docker run的参数命令帮助）

[root@localhost ~]# docker run --helpUsage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]Run a command in a new container  -a, --attach=[]             Attach to STDIN, STDOUT or STDERR  --add-host=[]               Add a custom host-to-IP mapping (host:ip)  --blkio-weight=0            Block IO (relative weight), between 10 and 1000  -c, --cpu-shares=0          CPU shares (relative weight)  --cap-add=[]                Add Linux capabilities  --cap-drop=[]               Drop Linux capabilities  --cgroup-parent=            Optional parent cgroup for the container  --cidfile=                  Write the container ID to the file  --cpu-period=0              Limit CPU CFS (Completely Fair Scheduler) period  --cpu-quota=0               Limit the CPU CFS quota  --cpuset-cpus=              CPUs in which to allow execution (0-3, 0,1)  --cpuset-mems=              MEMs in which to allow execution (0-3, 0,1)  -d, --detach=false          Run container in background and print container ID  --device=[]                 Add a host device to the container  --dns=[]                    Set custom DNS servers  --dns-search=[]             Set custom DNS search domains  -e, --env=[]                Set environment variables  --entrypoint=               Overwrite the default ENTRYPOINT of the image  --env-file=[]               Read in a file of environment variables  --expose=[]                 Expose a port or a range of ports  -h, --hostname=             Container host name  --help=false                Print usage  -i, --interactive=false     Keep STDIN open even if not attached  --ipc=                      IPC namespace to use  -l, --label=[]              Set meta data on a container  --label-file=[]             Read in a line delimited file of labels  --link=[]                   Add link to another container  --log-driver=               Logging driver for container  --log-opt=[]                Log driver options  --lxc-conf=[]               Add custom lxc options  -m, --memory=               Memory limit  --mac-address=              Container MAC address (e.g. 92:d0:c6:0a:29:33)  --memory-swap=              Total memory (memory + swap), '-1' to disable swap  --name=                     Assign a name to the container  --net=bridge                Set the Network mode for the container  --oom-kill-disable=false    Disable OOM Killer  -P, --publish-all=false     Publish all exposed ports to random ports  -p, --publish=[]            Publish a container's port(s) to the host  --pid=                      PID namespace to use  --privileged=false          Give extended privileges to this container  --read-only=false           Mount the container's root filesystem as read only  --restart=no                Restart policy to apply when a container exits  --rm=false                  Automatically remove the container when it exits  --security-opt=[]           Security Options  --sig-proxy=true            Proxy received signals to the process  -t, --tty=false             Allocate a pseudo-TTY  -u, --user=                 Username or UID (format: <name|uid>[:<group|gid>])  --ulimit=[]                 Ulimit options  --uts=                      UTS namespace to use  -v, --volume=[]             Bind mount a volume  --volumes-from=[]           Mount volumes from the specified container(s)  -w, --workdir=              Working directory inside the container[root@localhost ~]# 

五、运行docker镜像

命令：docker run [OPTIONS] images[:TAG]

e.g..  docker run -d 5caf8ed   （在后台运行ID为5caf8ed的镜像，注：-d为参数，指后台运行且打印运行容器ID，5caf8ed为镜像的ID前端部分，ID不一定要输全，只要能够区分开docker就知道要运行哪个）

[root@localhost ~]# docker imagesREPOSITORY                          TAG                 IMAGE ID            CREATED             VIRTUAL SIZEhub.c.163.com/wangjiaen/centos6.9   ssh                 5caf8ed79df7        9 weeks ago         370.9 MB[root@localhost ~]# docker run -d 5caf8ed28d26a28befb16feb8506df458871a8416f1e9ae02e253d363fa4bba38180e6a[root@localhost ~]#

六、查看正在运行的容器

命令：docker ps           

docker ps -a 列出所有容器

docker ps -l 最后创建的容器

其他参数不明白可以输入：docker ps --help自行查看（其他命令一样，不懂就--help，以后就不赘述了）

[root@localhost ~]# docker psCONTAINER ID        IMAGE               COMMAND               CREATED             STATUS              PORTS               NAMES28d26a28befb        5caf8ed             "/usr/sbin/sshd -D"   4 hours ago         Up 4 hours          22/tcp              cranky_wright       [root@localhost ~]#

七、进入容器内部

命令：docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

e.g..  docker exec -i -t IMAGE /bin/bash

e.g..  docker exec -it 28d bash   （-it即-i -t ，以交互模式进入容器ID为：28d*的容器内部，bash即执行/bin/bash脚本，如示例已经进入centos6.9内部）

[root@localhost ~]# docker psCONTAINER ID        IMAGE               COMMAND               CREATED             STATUS              PORTS               NAMES28d26a28befb        5caf8ed             "/usr/sbin/sshd -D"   4 hours ago         Up 4 hours          22/tcp              cranky_wright       [root@localhost ~]# docker exec -it 28d bash[root@28d26a28befb /]# lsbin  boot  devetc  home  liblib64  media  mnt  optproc  root  sbin  selinux  srvsys  tmp  usr  var[root@28d26a28befb /]# 

八、退出容器

命令：exit

[root@28d26a28befb /]# lsbin  boot  devetc  home  liblib64  media  mnt  optproc  root  sbin  selinux  srvsys  tmp  usr  var[root@28d26a28befb /]# exitexit[root@localhost ~]#

九、停止正在运行的容器

命令：docker stop ContainerID

e.g..  docker stop 28d26a28befb  （停止正在运行的ID为28d26a28befb的容器）

[root@localhost ~]# docker psCONTAINER ID        IMAGE               COMMAND               CREATED             STATUS              PORTS               NAMES28d26a28befb        5caf8ed             "/usr/sbin/sshd -D"   4 hours ago         Up 4 hours          22/tcp              cranky_wright       [root@localhost ~]# docker stop 28d26a28befb28d26a28befb[root@localhost ~]# docker psCONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES[root@localhost ~]#
