目录
1.安装docker服务配置镜像加速器
1.安装docker
1.安装工具 2.配置软件源
3.修改软件源配置
4.下载docker
5.设置开机docker自启
2.配置加速器 2.下载系统镜像Ubuntu、 centos
3.基于下载的镜像创建两个容器 容器名一个为自己名字全拼一个为首名字字母 4.容器的启动、 停止及重启操作
停止
启动 重启
进入容器 5.怎么查看正在运行的容器和所有容器 查看在运行的容器 查看所有容器 6.怎么退出容器 两种方法分别实现
进入容器
退出
第一种exit
第二种 ctrld / ctrlq
7.怎么连接到运行的容器
1.使用dockers exec
2.使用nsenter命令
8.查看容器或镜像的内部信息
查看容器内部信息
查看镜像的详细信息
9.如何查看所有镜像 1.安装docker服务配置镜像加速器
1.安装docker
1.安装工具 [rootbogon]# yum install -y yum-utils device-mapper-persistent-data lvm2 2.配置软件源 [rootbogon yum.repos.d]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo Loaded plugins: fastestmirror adding repo from: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo grabbing file https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo repo saved to /etc/yum.repos.d/docker-ce.repo 3.修改软件源配置 [rootbogon yum.repos.d]# sed -i sdownload.docker.commirrors.aliyun.com/docker-ce /etc/yum.repos.d/docker-ce.repo 4.下载docker yum makecache fast yum -y install docker-ce 5.设置开机docker自启 [rootbogon yum.repos.d]# systemctl enable docker.service Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service. 2.配置加速器 2.下载系统镜像Ubuntu、 centos 3.基于下载的镜像创建两个容器 容器名一个为自己名字全拼一个为首名字字母 4.容器的启动、 停止及重启操作
停止 启动 重启 进入容器 [rootbogon ~]# docker exec -it wangjiasheng /bin/bash rootdec77c79bb91:/# 5.怎么查看正在运行的容器和所有容器
我又创建了一个容器然后停止它现在有三个容器两个在运行 查看在运行的容器 查看所有容器 6.怎么退出容器 两种方法分别实现
进入容器 [rootbogon ~]# docker exec -it wjs /bin/bash [root37934146b020 /]# 退出
第一种exit 第二种 ctrld / ctrlq 7.怎么连接到运行的容器
1.使用dockers exec
使用 docker exec 命令docker exec 命令用于在正在运行的容器内执行命令。你可以使用该命令在容器内部打开一个新的终端并与容器进行交互。需要指定容器的名称或容器ID作为参数。例如
docker exec -it 容器名称或ID /bin/bash [rootbogon ~]# docker exec -it wjs /bin/bash [root37934146b020 /]# 2.使用nsenter命令 使用 nsenter 命令nsenter 是一个能够进入到命名空间的工具可以用来连接到已经运行的容器。首先获取容器的PID可以使用 docker inspect 命令来查找容器的PID。然后使用 nsenter 命令以附加模式连接到容器。例如 docker inspect --format {{.State.Pid}} 容器名称或ID sudo nsenter -t 容器PID -m -u -i -n -p /bin/bash 这将在容器内部打开一个新的 Bash 终端并允许你直接与容器进行交互。
以上方法中使用 -it 参数可以实现交互式的终端连接/bin/bash 是默认的 shell可以根据容器内部的配置来选择其他 shell。 8.查看容器或镜像的内部信息 查看容器内部信息 docker inspect 容器名或容器ID 查看镜像的详细信息 docker inspect 镜像名或镜像ID[rootbogon ~]# docker inspect wjs [ { Id:
