Linux 多应用程序docker自动部署脚本可以结合jenkins分布式部署

参数:

镜像名:端口的格式:版本号

例如:spring-client:8764:0.0.1

1.先用maven install 打包项目到target目录下

2.项目对应的Dockerfile路径为:/src/main/docker/Dockerfile

3.脚本自动复制Dockerfile和程序文件自动打包镜像部署

4.docker命令运行时加入--restart unless-stopped 可以容器随docker自启

project=("spring-client:8764:0.0.1" "spring-system:8770:0.0.1" "spring-eureka:8761:0.0.1")
mainDir=/opt/jenkins
jenkinsDir=/root/.jenkins/workspace/spring-boot-xinjiang
#判断主文件夹是否存在,不存在创建
if [ ! -d $mainDir ]; then
  mkdir $mainDir
fi
#循环数组创建每个项目的文件夹
for var in ${project[@]} 
do
  OLD_IFS="$IFS"  
  IFS=":"  
  array=($var)  
  IFS="$OLD_IFS"
  name=${array[0]}
  port=${array[1]}
  version=${array[2]}  
  echo 项目名称$name;
  if [ ! -d $mainDir/$name ]; then
    echo "项目目录不存在,创建项目目录"
    mkdir $mainDir"/"$name
  fi
  cd $jenkinsDir;
  jarName=$name/target/$name-1.0.0.jar
  if [ -f $jarName ]; then
    echo "jar源文件存在,正在复制"
    #复制程序文件(war/jar)的名称
    cp $jarName $mainDir/$name/$name-$version-SNAPSHOT.jar
  else
    echo "jar源文件不存在"
  fi
  #Dockerfile文件的路径
  dockerFileName=$name/src/main/docker/Dockerfile
  if [ -f $dockerFileName ]; then
    echo "docker文件存在,正在复制"
    #复制Dockerfile程序文件的名称
    cp $dockerFileName $mainDir/$name
  else
    echo "docker文件不存在"
  fi
  if [ -f $dockerFileName ] && [ -f $jarName ]; then
    cd $mainDir/$name
    if docker ps -a|grep -i $name;then
      docker stop $name
      docker rm $name
    fi
    imagesid=`docker images|grep -i $name | awk '{print $3}'`

    if [ "$imagesid" == "" ];then
      echo  "镜像不存在"
    else
      echo  "镜像存在删除后构建"
      if docker ps -a|grep -i $name;then
       echo "镜像容器存在,正在停止容器"
       docker stop $name
       echo "镜像容器删除"
       docker rm $name
      fi
      docker rmi $imagesid -f
    fi
     docker build -t $name .
     echo "镜像构建成功"
     echo "容器构建中"
     docker run -d -p $port:$port --name $name --restart unless-stopped $dockerName $name
     echo "容器启动成功"
  else
    echo "镜像构建失败"
  fi
done
exit 0

The Future of Linux Software: Will Flatpak and Snap Replace Native Desktop Apps?The Future of Linux Software: Will Flatpak and Snap Replace Native Desktop Apps?Apr 25, 2025 am 09:10 AM

For years, Linux software distribution relied on native formats like DEB and RPM, deeply ingrained in each distribution's ecosystem. However, Flatpak and Snap have emerged, promising a universal approach to application packaging. This article exami

What are the differences in how Linux and Windows handle device drivers?What are the differences in how Linux and Windows handle device drivers?Apr 25, 2025 am 12:13 AM

The differences between Linux and Windows in handling device drivers are mainly reflected in the flexibility of driver management and the development environment. 1. Linux adopts a modular design, and the driver can be loaded and uninstalled dynamically. Developers need to have an in-depth understanding of the kernel mechanism. 2. Windows relies on the Microsoft ecosystem, and the driver needs to be developed through WDK and signed and certified. The development is relatively complex but ensures the stability and security of the system.

Compare and contrast the security models of Linux and Windows.Compare and contrast the security models of Linux and Windows.Apr 24, 2025 am 12:03 AM

The security models of Linux and Windows each have their own advantages. Linux provides flexibility and customizability, enabling security through user permissions, file system permissions, and SELinux/AppArmor. Windows focuses on user-friendliness and relies on WindowsDefender, UAC, firewall and BitLocker to ensure security.

How does hardware compatibility differ between Linux and Windows?How does hardware compatibility differ between Linux and Windows?Apr 23, 2025 am 12:15 AM

Linux and Windows differ in hardware compatibility: Windows has extensive driver support, and Linux depends on the community and vendors. To solve Linux compatibility problems, you can manually compile drivers, such as cloning RTL8188EU driver repository, compiling and installing; Windows users need to manage drivers to optimize performance.

What are the differences in virtualization support between Linux and Windows?What are the differences in virtualization support between Linux and Windows?Apr 22, 2025 pm 06:09 PM

The main differences between Linux and Windows in virtualization support are: 1) Linux provides KVM and Xen, with outstanding performance and flexibility, suitable for high customization environments; 2) Windows supports virtualization through Hyper-V, with a friendly interface, and is closely integrated with the Microsoft ecosystem, suitable for enterprises that rely on Microsoft software.

What are the main tasks of a Linux system administrator?What are the main tasks of a Linux system administrator?Apr 19, 2025 am 12:23 AM

The main tasks of Linux system administrators include system monitoring and performance tuning, user management, software package management, security management and backup, troubleshooting and resolution, performance optimization and best practices. 1. Use top, htop and other tools to monitor system performance and tune it. 2. Manage user accounts and permissions through useradd commands and other commands. 3. Use apt and yum to manage software packages to ensure system updates and security. 4. Configure a firewall, monitor logs, and perform data backup to ensure system security. 5. Troubleshoot and resolve through log analysis and tool use. 6. Optimize kernel parameters and application configuration, and follow best practices to improve system performance and stability.

Is it hard to learn Linux?Is it hard to learn Linux?Apr 18, 2025 am 12:23 AM

Learning Linux is not difficult. 1.Linux is an open source operating system based on Unix and is widely used in servers, embedded systems and personal computers. 2. Understanding file system and permission management is the key. The file system is hierarchical, and permissions include reading, writing and execution. 3. Package management systems such as apt and dnf make software management convenient. 4. Process management is implemented through ps and top commands. 5. Start learning from basic commands such as mkdir, cd, touch and nano, and then try advanced usage such as shell scripts and text processing. 6. Common errors such as permission problems can be solved through sudo and chmod. 7. Performance optimization suggestions include using htop to monitor resources, cleaning unnecessary files, and using sy
