一、Docker常用命令(1)镜像类命令
docker search :搜索镜像
docker login :登录到registry(仓库)
docker image pull :拉取镜像到本地
docker image push :推送镜像到registry(仓库)
docker image ls :查看本地有多少镜像
docker image rm :删除镜像
docker image build :基于dockerfile构建镜像
docker image inspect :查看镜像详细信息
docker image tag :给镜像打上标签
docker image save :导出镜像
docker image load :导入镜像(2)容器类命令
docker container run :基于镜像创建并启动一个容器，如果镜像不存在则会使用拉取下来再启动
-i :交互式与容器
-t :启动一个虚拟终端
-d :让容器运行在后台
docker container stop :停止容器
docker container start :启动已经停止的容器
docker container restart :重新启动容器
docker container rm :删除容器
docker container kill :杀死一个容器
docker container exec :对内部容器执行命令
-i :即使没有附加也保持STDIN 打开
-t :分配一个伪终端
docker container attach :进入容器内部
docker container ps :查看启动的容器
docker container ps -a :查看所有容器，包括启动停止的容器
docker logs :查看容器内部日志
docker port :查看容器映射的端口
docker top :显示容器进程信息
docker stats :显是容器占用资源信息[root@elk_134 ~]# docker search nginx

(4)docker image rm，删除镜像
[root@elk_134 ~]# docker image rm nginx

[root@elk_134 ~]# docker container run --name "nginx-web2" -d nginx:latest
9d9e155db3199b01930c98c8efe17196eba71f4ff2edcea2b66a7265a87d3c65
[root@elk_134 ~]# docker run --name "b1" -dit busybox

(2)docker container ps，查看启动的容器
[root@elk_134 ~]# docker container ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9d9e155db319 nginx:latest "nginx -g ‘daemon of…" 56 seconds ago Up 53 seconds 80/tcp nginx-web2
313d9d578bf5 alivv/elasticsearch-head "/bin/sh -c ‘node_mo…" 2 months ago Up 9 days 0.0.0.0:9100->9100/tcp es-head
(3)docker container inspect，查看容器详细信息
[root@elk_134 ~]# docker container inspect nginx-web2 | grep "IPAddress"
"SecondaryIPAddresses": null,
"IPAddress": "172.17.0.3",
"IPAddress": "172.17.0.3",
(4)docker container exec，docker container attach ，进入容器内部，nginx容器第一个进程ID为nginx所以需要exec执行/bin/bash解释器进入内部
而b1容器第一个进程为sh进程如果exit直接退出容器就会终止(容器内部程序要工作在前台)
[root@elk_134 ~]# docker container exec -it nginx-web2 /bin/bash
root@9d9e155db319:/# ls /usr/share/nginx/html/
50x.html index.html
[root@elk_134 ~]# docker container attach b1
/ #
/ #
/ # ls
bin dev etc home proc root sys tmp usr var
/ #
/ # ps
PID USER TIME COMMAND
1 root 0:00 sh
7 root 0:00 ps
ctrl + P，ctrl + Q退出
(5)docker container stop，关闭容器
[root@elk_134 ~]# docker container stop nginx-web2
nginx-web2
(6)docker container start，启动容器
[root@elk_134 ~]# docker container start nginx-web2
nginx-web2
(7)docker container top，查看容器内部进程信息
[root@elk_134 ~]# docker container top nginx-web2
UID PID PPID C STIME TTY TIME CMD
root 100084 100060 0 21:13 ? 00:00:00 nginx: master process nginx -g daemon off;
101 100145 100084 0 21:13 ? 00:00:00 nginx: worker process
(8)docker container stats，查看容器资源信息
[root@elk_134 ~]# docker container stats
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
d2cc7b34daa0 b1 0.00% 56KiB / 15.56GiB 0.00% 648B / 0B 111kB / 594kB 1
9d9e155db319 nginx-web2 0.00% 1.359MiB / 15.56GiB 0.01% 648B / 0B 446kB / 0B 2
313d9d578bf5 es-head 0.00% 12.92MiB / 15.56GiB 0.08% 27.5kB / 687kB 86.9MB / 0B 11
(9)docker container rm，删除容器，需要先停止容器才可删除
[root@elk_134 ~]# docker container stop nginx-web2
nginx-web2
[root@elk_134 ~]# docker container rm nginx-web2
nginx-web2一步一步来！！！！！！！！！！！！！！！！！！！！！！
其实很简单哒！！！！！！！！！！！！！！！！！！！！！
