1. 从镜像启动一个容器


1.1 前台启动容器

root@node16:~# docker images

1.2 后台启动容器

### 后台启动容器，并生成随机的容器ID和名称
root@node16:~# docker container ls -a
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS                          PORTS     NAMES

1.3 创建容器时并进入容器（依赖于"-i"(保持一个标准输入)和"-t"(分配一个tty终端)两个参数）

### 会打开一个bash并直接进入到容器，并随机生成容器ID和名称
root@node16:~# docker image ls
REPOSITORY   TAG       IMAGE ID       CREATED        SIZE
nginx        latest    605c77e624dd   2 months ago   141MB

1.4 自定义容器名称（一般在单机上会有点作用，在k8s集群中很少去自定义容器名称）

1.5 单次运行容器（容器退出后会自动删除，主要用于临时验证镜像内容是否符合标准，如配置文件目录组织结构等信息）

root@node16:~# docker run -it --rm --name V1nginx nginx bash
root@d46480b32cb4:/# exit
exit
root@node16:~# docker container ls -a |grep V1nginx         #发现容器没有了

5.3 获取容器的PID信息

root@node15:~# docker container ls -a
CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS                                                                                                                   NAMES
15acaf3a4cff   nginx     "/docker-entrypoint.…"   18 minutes ago   Up 18 minutes   80/tcp, 0.0.0.0:50003->53/udp, :::50003->53/udp, 172.16.1.15:50001->80/udp, 0.0.0.0:50002->443/tcp, :::50002->443/tcp   myNginx-test05
root@node15:~# docker container inspect -f "{{.State.Pid}}" 15acaf3a4cff

root@node15:~# docker container inspect -f "{{.State.Pid}}"  myNginx-test05
2855
root@node15:~#


6. 进入到正在运行的容器


6.1 使用attach命令连接正在运行的容器（生产环境不推荐使用，因为使用exit退出容器后容器会跟着自动关闭）

root@node15:~# docker container ls -a
CONTAINER ID   IMAGE     COMMAND                  CREATED              STATUS              PORTS     NAMES

root@node15:~# docker container  ls -a
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS                          PORTS     NAMES

root@node15:~#


6.2 使用exec命令（生产环境推荐使用这种方式）

root@node15:~# docker container ls -a
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS     NAMES

root@node15:~#

Docker容器操作_docker_20

6.3 使用nsenter命令(生产环境也推荐使用这种方式，但需要单独安装nsenter命令)

root@node15:~# apt-get install util-linux       #安装nsenter命令
root@node15:~# docker container ls -a
CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS     NAMES
39cb32823eb0   nginx     "/docker-entrypoint.…"   18 minutes ago   Up 10 minutes   80/tcp    myNginx-test01
root@node15:~# docker container inspect -f "{{.State.Pid}}" myNginx-test01        #获取容器PID
2559
root@node15:~# nsenter -t 2559 -m -u -i -n -p           #通过容器的PID连接运行中的容器
root@39cb32823eb0:/# cat /etc/issue
Debian GNU/Linux 11 \n \l

root@39cb32823eb0:/# cat /etc/resolv.conf 
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients directly to

# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

6.4 脚本方式连接容器

root@node15:/data/scripts# pwd 
/data/scripts
root@node15:/data/scripts# cat docker_connect.sh 
#!/bin/bash
function docker_connect(){
    CONTAINER_NAME=$1

    nsenter -t ${CONTAINER_PID} -m -u -i -n -p
