在Docker中使用exec命令 在Docker中,我们可以通过在ENTRYPOINT中使用exec命令来执行多条命令。下面是一个示例Dockerfile: FROMubuntuCOPYscript.sh /usr/local/bin/RUNchmod +x /usr/local/bin/script.shENTRYPOINT["exec","/usr/local/bin/script.sh"] 1. 2. 3.
/bin/shecho"Running multiple commands"echo"Hello World!"# 你想要运行的其他命令exec"$@" 1. 2. 3. 4. 5. 修改Dockerfile: COPYstartup.sh .RUNchmod +x startup.shENTRYPOINT["/app/startup.sh"]CMD["/app/myscript.sh"] 1. 2. 3. 4. 5. 6. 在这个例子中,start.sh声明了一些命令并以ex...

(2)CMD与ENTRYPOINT区别 两者都是容器启动的时候要执行的命令,CMD命令只有最后一个会生效,后面不支持追加命令,会被替代。ENTRYPOINT不会被替代,可以追加命令。 CMD #vim cmdFROM centos CMD ["ls","-a"]#构建docker build -f cmd -t cmd_test .#运行,发现我们的ls-a命令生效docker run cmd_test ...
A container's main running process is theENTRYPOINTand/orCMDat the end of theDockerfile. It's best practice to separate areas of concern by using one service per container. That service may fork into multiple processes (for example, Apache web server starts multiple worker processes). It's ...
