SUSE中Docker的配置和使用
（图片来源网络，侵删）
SUSE，全称SUSE Linux Enterprise Server，是一个开源的企业级Linux发行版，Docker是一种开源的应用容器引擎，它允许开发者将应用及其依赖打包到一个可移植的容器中，然后发布到任何流行的Linux机器或Windows机器上，也可以实现虚拟化，在SUSE中配置和使用Docker，可以分为以下几个步骤：
1. 安装Docker
我们需要在SUSE系统中安装Docker，可以通过以下命令进行安装：
sudo zypper install docker安装完成后，可以使用以下命令启动Docker服务：
sudo systemctl start docker并设置Docker服务开机自启：
sudo systemctl enable docker2. 验证Docker安装
安装完成后，我们可以使用以下命令查看Docker的版本信息，以验证Docker是否已经成功安装：
docker version如果Docker已经成功安装，该命令将显示Docker的版本信息。
3. Docker的基本操作
Docker有许多基本操作，如拉取镜像、运行容器、查看容器状态等，以下是一些常用的Docker命令：
命令 描述 docker pull [选项] [镜像名[:标签]] 从仓库中拉取镜像 docker run [选项] 镜像名[:标签] 运行一个新的容器 docker ps [选项] 列出运行中的容器 docker stop [选项] 容器ID或容器名 停止一个正在运行的容器 docker rm [选项] 容器ID或容器名 删除一个容器 docker images [选项] 列出本地所有的镜像 docker rmi [选项] 镜像ID或镜像名 删除一个本地镜像4. Docker的网络和存储管理
Docker提供了网络和存储的管理功能，可以方便地创建和管理网络和数据卷，以下是一些常用的Docker命令：
命令 描述 docker network create [选项] 网络名 创建一个新的网络 docker network connect [选项] 网络名 容器名或容器ID 将一个容器连接到一个网络 docker network ls [选项] 列出所有的网络 docker volume create [选项] 数据卷名 创建一个新的数据卷 docker volume ls [选项] 列出所有的数据卷 docker volume prune [选项] 删除未使用的数据卷5. Docker的高级功能
除了基本的操作外，Docker还有许多高级功能，如容器编排、服务发现、负载均衡等，以下是一些常用的Docker命令：
命令 描述 dockercompose up [选项] 启动所有在dockercompose.yml文件中定义的服务 dockercompose down [选项] 停止并移除所有在dockercompose.yml文件中定义的服务 docker stack deploy [选项] [堆栈名] 部署一个新的堆栈 docker service ls [选项] 列出所有的服务 docker service logs [选项] 服务名或服务ID 查看服务的日志相关问答FAQs
问题1：在SUSE中安装Docker时，提示“No candidate for package provider ‘docker’ found”怎么办？
答：这个问题可能是由于没有添加正确的软件源导致的，你可以尝试添加Docker的官方软件源，然后再进行安装，在SUSE中，可以通过以下命令添加Docker的官方软件源：
sudo sh c echo "deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_20.04/ /" > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list && sudo apt update && sudo apt install noinstallrecommends libltdl7 && sudo apt update && sudo apt install containerd.io && sudo systemctl start containerd && sudo systemctl enable containerd && sudo apt install ctr curl podman buildah snapd || exit $? && curl L "https://github.com/containerd/containerd/releases/download/v1.4.3/containerd.io1.4.3linuxamd64.tar.gz" o containerd.io1.4.3linuxamd64.tar.gz && sudo tar xzf containerd.io1.4.3linuxamd64.tar.gz C /usr/local/bin stripcomponents=1 containerd.io && rm rf containerd.io1.4.3linuxamd64.tar.gz && sudo systemctl restart containerd && sudo systemctl status containerd || exit $? && which containerd && which ctr && which podman && which buildah && which snapd && curl L "https://get.sdkman.io" > /tmp/sdkmaninstaller && chmod +x /tmp/sdkmaninstaller && sudo /tmp/sdkmaninstaller >> /dev/null && rm /tmp/sdkmaninstaller && source "$HOME/.sdkman/bin/sdkmaninit.sh" && sdk version && sdk install grep zip unzip jq coreutils tree procps less openssh golang nodejs yarn python java nvm && source "$HOME/.sdkman/bin/sdkmaninit.sh" && sdk version && sdk use go latest && go version && go env && which go && which node && which yarn && which python && which java && which nvm && which ctr && which podman && which buildah && which snapd || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? || true || exit $? verbose info debug trace help fail fast failfast pipefail errexit localerrexit input output error return code signal termination status code failure reason error message progress bytes transferred bytes expected total time elapsed real time user CPU used sys CPU used percent of CPU used elapsed user time elapsed sys time elapsed real user time elapsed real sys time wait queue length number of threads number of processes running number of threads in process number of signals received number of open file handles number of open network connections number of locks held number of messages in queue number of semaphores in set number of shared libraries loaded number of text segment page faults number of voluntary context switches number of involuntary context switches number of block input/output operations number of messages sent number of messages received number of messages copied number of messages flushed number of messages dropped number of clock tick seconds number of vnodes currently used number of TTY users current working directory home directory root directory current directory command line arguments environment variables process ID process group ID session ID tty type tty device name terminal type window size rows columns width height xpixelsize ypixelsize character cell width character cell height character width character height character cells horizontal offset vertical offset text foreground color background color text color map
