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. 4. 5. 6. 在上面的示例中,我们将一个脚本...

当ENTRYPOINT 与 CMD 同时给出时,CMD 中的内容会作为 ENTRYPOINT 定义命令的参数,最终执行容器启动的还是 ENTRYPOINT 中给出的命令。 2.5 LABEL LABEL 指令用来指定生成镜像的元数据标签信息。格式为: LABEL <key>=<value><key>=<value><key>=<value>... ...
作为ENTRYPOINT的默认参数 shell 模式 一个dockerfile中只能有一个CMD,如果有多个只有最后的CMD生效 所以...
(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 ...
ENTRYPOINT一般跟CMD配合起来一起使用。因为CMD里的内容能作为参数传到ENTRYPOINT里使用。官网里是这么介绍的:An ENTRYPOINT allows you to configure a container that will run as an executable. 换成中文意思是说ENTRYPOINT可以让你的容器功能表现得像一个可执行程序一样。
--entrypoint Overwrite the default ENTRYPOINT of the image -e, --env Set environment variables --env-file Read in a file of environment variables --expose Expose a port or a range of ports --gpus API 1.40+ GPU devices to add to the container ('all' to pass all GPUs) --group-add ...
The RUN, CMD, and ENTRYPOINT instructions all have two possible forms: INSTRUCTION ["executable","param1","param2"] (exec form) INSTRUCTION command param1 param2 (shell form) The exec form makes it possible to avoid shell string munging, and to invoke commands using a specific command shell...
