docker--常用命令
前戏
我们使用docker --help来查看下都有哪些命令

docker search jenkins # 搜索所有的jenkins的docker镜像

获取镜像
从docker registry获取镜像的命令是docker pull。命令格式是:
docker pull [选项][docker registry地址] 仓库名:标签
docker是把应用程序和其依赖打包在image文件里面,只有通过这个镜像文件才能生成docker容器。
一个image文件可以生成多个容器实例。
可以使用docker pull命令来从仓库获取所需要的镜像,比如下载一个jenkins的镜像
docker pull jenkins # 获取jenkins镜像
[root@HH ~]# docker pull jenkins Using default tag: latest latest: Pulling from library/jenkins 55cbf04beb70: Pull complete 1607093a898c: Pull complete 9a8ea045c926: Pull complete d4eee24d4dac: Pull complete c58988e753d7: Pull complete 794a04897db9: Pull complete 70fcfa476f73: Pull complete 0539c80a02be: Pull complete 54fefc6dcf80: Pull complete 911bc90e47a8: Pull complete 38430d93efed: Pull complete 7e46ccda148a: Pull complete c0cbcb5ac747: Pull complete 35ade7a86a8e: Pull complete aa433a6a56b1: Pull complete 841c1dd38d62: Pull complete b865dcb08714: Pull complete 5a3779030005: Pull complete 12b47c68955c: Pull complete 1322ea3e7bfd: Pull complete Digest: sha256:eeb4850eb65f2d92500e421b430ed1ec58a7ac909e91f518926e02473904f668 Status: Downloaded newer image for jenkins:latest docker.io/library/jenkins:latest
拉取指定版本,用:
docker pull jenkins:1.12 # 获取jenkins1.12的镜像
下载过程可以看出镜像是由多层存储构成的。下载也是一层一层,并非单一的文件。
下载过程中给出每一层的前12位ID。下载结束后会给出sha246的文件一致性校验值
查看docker镜像
docker images # 查看docker镜像
删除docker镜像
如果要移除本地的镜像,可以使用docker rmi命令(在删除镜像之前先用docker rm删除依赖于这个镜像的所有容器)。注意docker rm 命令是移除容器。
docker rmi imageID #删除docker镜像 或者 docker rmi 镜像名字
删除所有的镜像
docker rmi `docker images -aq` #一次性删除所有镜像记录,反单引号
导出docker镜像
有时候我们的镜像,别人也要使用,我们可以把我们的镜像导出给别人使用,使用docker save命令
docker save jenkins > /tmp/jenkins.tar.gz # 导出docker镜像到本地的tmp目录下
导入docker镜像
上面别人给我们导出了他的镜像,那我们就要导入了,删除自己的docker镜像在导入
docker load < /tmp/jenkins.tar.gz # 导入本地镜像到docker镜像库
导入完之后查看docker镜像库
# docker images REPOSITORY TAG IMAGE ID CREATED SIZE jenkins latest cd14cecfdb3a 14 months ago 696MB
启动docker容器
启动容器有两种方式,一种是基于镜像新建一个容器并启动,另外一个是将在终止状态(stopped)的容器重新启动。
因为Docker的容器实在太轻量级了,很多时候用户都是随时删除和新创建容器。
新建容器并启动
使用docker run启动容器
[root@HH ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE jenkins latest cd14cecfdb3a 14 months ago 696MB [root@HH ~]# docker run cd14
这样就启动了一个容器,但这样有缺点,我们关掉窗口或者ctrl+c就终止了,所以在启动的时候我们可以加上参数-d,表示后台启动
[root@HH ~]# docker run -d jenkins 也可以通过id启动 4ee88fb080c7718fd68bc5dfbea01e10048df8fd00e461cdec166be594064293
docker run就是运行容器的命令。
参数
- -it : -i 是交互式操作,-t是终端
- -rm : 容器退出后将其删除。也可以不指定参数,手动docker rm,使用-rm可以避免浪费空间。
- bash : 指定用交互式的shell,因此需要bash命令
当利用docker run来创建容器时,Docker在后台运行的标准操作包括
- 检查本地是否存在指定的镜像,不存在就从公有仓库下载
- 利用镜像创建并启动一个容器
- 分配一个文件系统,并在只读的镜像层外面挂在一层 可读写层
- 从宿主机配置的网桥接口桥接一个虚拟 接口到容器中去
- 从地址池配置一个 ip地址给容器
- 执行用户指定的 应用程序
- 执行完毕后容器被终止
查看正在运行的容器
通过docker ps就可以查看运行的容器
[root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 4ee88fb080c7 jenkins "/bin/tini -- /usr/l…" 4 minutes ago Up 4 minutes 8080/tcp, 50000/tcp brave_wilson
后面的NAMES参数是docker给我们生成的,我们也可以自定义,在启动的时候加上--name参数
[root@HH ~]# docker run -d --name MyJenkins jenkins 1603ebfad9aaff6c2ec1bfa6e5300ac711a716d8bea3b0fed37c6bbc38b354b1 [root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 1603ebfad9aa jenkins "/bin/tini -- /usr/l…" 9 seconds ago Up 8 seconds 8080/tcp, 50000/tcp MyJenkins
停止正在运行的容器
通过docker stop 容器id/names都可以停止容器
[root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 4ee88fb080c7 jenkins "/bin/tini -- /usr/l…" 7 minutes ago Up 7 minutes 8080/tcp, 50000/tcp brave_wilson [root@HH ~]# [root@HH ~]# docker stop brave_wilson brave_wilson [root@HH ~]# docker stop 40db 40db
查看所有的容器
docker ps -a 可以查看停止和运行的容器
[root@HH ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 40db302d030b jenkins "/bin/tini -- /usr/l…" 2 minutes ago Exited (143) About a minute ago admiring_morse 4ee88fb080c7 jenkins "/bin/tini -- /usr/l…" 9 minutes ago Exited (143) 2 minutes ago brave_wilson d6e046c9d2ff cd14 "/bin/tini -- /usr/l…" 12 minutes ago Exited (130) 11 minutes ago vigorous_greider
查看容器详细信息
docker inspect 容器名/容器id
[root@WC ~]# docker inspect mycentos

删除容器记录
通过docker rm 容器ID来删除
[root@dce88 ~]# docker rm -h
Flag shorthand -h has been deprecated, please use --help
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
Remove one or more containers # 删除一个或多个容器
Options:
-f, --force Force the removal of a running container (uses SIGKILL) # 强制删除一个正在运行的容器(使用SIGKILL)。
-l, --link Remove the specified link # 删除指定的链接
-v, --volumes Remove anonymous volumes associated with the container # 删除与容器相关的匿名卷
基本使用

通过rm删除的是已停止的,如果是正在运行的会报错
[root@HH ~]# docker rm 00436 Error response from daemon: You cannot remove a running container 00436eade5368cad1f93e9e1ef9c3cc5da3738a0f17a7e1b6e2669e7c379ca54. Stop the container before attempting removal or force remove
可以通过-f参数强制删除
[root@HH ~]# docker rm -f 00436 00436 [root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3c4cb6a23761 jenkins "/bin/tini -- /usr/l…" 30 minutes ago Up 30 minutes 50000/tcp, 0.0.0.0:8000->8080/tcp myjenkins
一次性删除所有容器记录
docker rm `docker ps -aq` # 一次性删除所有容器id记录
` ` #反引号是取命令的运行结果
启动终止状态的容器
通过docker start 容器ID来启动

进入容器
使用-d参数时,容器启动后会进入后台。某些时候需要进入容器进行操作,有很多种方法,包括使用docker attach命令或nsenter工具等。
docker exec -it 容器id /bin/bash docker attach 容器id
提交创建自定义的镜像
#1.我们进入交互式的centos容器中,发现没有vim命令 docker run -it centos
#2.在当前容器中,安装一个vim yum install -y vim
#3.安装好vim之后,exit退出容器 exit
#4.查看刚才安装好vim的容器记录 docker container ls -a
#5.提交这个容器,创建新的image docker commit 059fdea031ba chaoyu/centos-vim
#6.查看镜像文件 [root@master /home]docker images REPOSITORY TAG IMAGE ID CREATED SIZE chaoyu/centos-vim latest fd2685ae25fe 5 minutes ago 348MB
外网访问容器
上面我们使用-d参数后台启动了jenkins,但是还不能访问它,如果想访问,还需要加-p或者-P参数,返回的是容器ID
[root@HH ~]# docker run -d --name myjenkins -p 8000:8080 jenkins 3c4cb6a2376121fdc71303232cd3e68ffb6683c2c24aeba544c3d65e17c0e9be [root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3c4cb6a23761 jenkins "/bin/tini -- /usr/l…" 5 seconds ago Up 4 seconds 50000/tcp, 0.0.0.0:8000->8080/tcp myjenkins
-p 8000:8080表示将本机的8000端口映射到容器的8080端口,浏览器访问8000端口就是访问容器的8080端口
设置成功后,我们在浏览器输入如下的地址就能看到jenkins的页面了
http://49.235.160.132:8000
-P 参数会随机映射端口到容器开放的网络端口
[root@HH ~]# docker run -d -P jenkins 00436eade5368cad1f93e9e1ef9c3cc5da3738a0f17a7e1b6e2669e7c379ca54 [root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 00436eade536 jenkins "/bin/tini -- /usr/l…" 5 seconds ago Up 3 seconds 0.0.0.0:32769->8080/tcp, 0.0.0.0:32768->50000/tcp angry_curran 3c4cb6a23761 jenkins "/bin/tini -- /usr/l…" 3 minutes ago Up 3 minutes 50000/tcp, 0.0.0.0:8000->8080/tcp myjenkins
上面会将宿主机的32769端口映射到容器的8080端口,访问下面地址也是一样的
http://49.235.160.132:8000
温馨提示:如果访问失败的话,请检查自己的防火墙,以及云服务器的安全组
查看容器日志
不间断显示log:docker logs -f 容器ID
[root@HH ~]# docker logs -f 00436 Running from: /usr/share/jenkins/jenkins.war webroot: EnvVars.masterEnvVars.get("JENKINS_HOME") Sep 28, 2019 2:37:31 PM Main deleteWinstoneTempContents WARNING: Failed to delete the temporary Winstone file /tmp/winstone/jenkins.war Sep 28, 2019 2:37:31 PM org.eclipse.jetty.util.log.JavaUtilLog info INFO: Logging initialized @1325ms Sep 28, 2019 2:37:31 PM winstone.Logger logInternal INFO: Beginning extraction from war file Sep 28, 2019 2:37:33 PM org.eclipse.jetty.util.log.JavaUtilLog warn WARNING: Empty contextPath Sep 28, 2019 2:37:33 PM org.eclipse.jetty.util.log.JavaUtilLog info INFO: jetty-9.2.z-SNAPSHOT
查看指定容器的端口映射
现在我们已经映射了两个端口,一个是32769,一个是8000,如下
[root@HH ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 00436eade536 jenkins "/bin/tini -- /usr/l…" 8 minutes ago Up 8 minutes 0.0.0.0:32769->8080/tcp, 0.0.0.0:32768->50000/tcp angry_curran 3c4cb6a23761 jenkins "/bin/tini -- /usr/l…" 12 minutes ago Up 12 minutes 50000/tcp, 0.0.0.0:8000->8080/tcp myjenkins
使用docker port 容器ID就可以查看端口映射
[root@HH ~]# docker port 00436 50000/tcp -> 0.0.0.0:32768 8080/tcp -> 0.0.0.0:32769

总结
镜像 docker image ls # 查看所有镜像 docker images # 查看所有镜像 docker pull 镜像名 # docker仓库,dockerhub docker push 镜像名 # 把本地的镜像推送到 dockerhub仓库 docker search 镜像名 # 搜索镜像 docker rmi 容器ID # 删除镜像 docker version # 查看docker版本,查看到server 和client两个端 systemctl start docker # 启动docker docker save 镜像名 > /data/centos.tar.gz # 导出镜像 docker load < /data/centos.tar.gz # 导入镜像 docker run 镜像名 # 运行镜像文件,产生一个容器实例 容器 docker start 容器id # 启动容器 docker stop 容器id # 停止容器 docker exec -it 容器id # 进入正在运行的容器 -i 交互式操作 -t 开启一个终端 docker run 镜像名 # 创建容器实例 docker rm 容器id # 删除容器记录,必须提前docker stop 容器id ,只能杀死已经停止的容器 docker rm -f 容器id # 可以删除运行中的容器 docker ps # 查看容器正在运行记录 docker ps -aq # 显示所有容器记录的id号 -a 显示所有容器记录 -q 显示容器id docker rm `docker ps -aq` # 一次性删除所有容器记录 docker container ls # 查看容器正在运行记录 docker commit 容器id记录 # 提交这个容器,创建一个新的镜像 docker logs # 查看容器运行日志 -f #不间断打印容器日志 docker port #查看容器的端口映射关系(外部访问到容器内的端口) docker run -d centos -P -d 后台运行 -P 随机映射端口 -p 9000(宿主机):5000(容器内) --name 给创建的容器记录,添加别名
