如果用户启动容器时手动指定了运行的命令(作为 run 的参数),则会覆盖掉 CMD 指定的命令。 如容器启动时进入 bash: CMD /bin/bash 或者可以用exec写法 CMD ["/bin/bash"] 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...

docker run [OPTIONS]可以让image使用者完全控制container的生命周期,允许image使用者覆盖所有image开发者在执行docker build时所设定的参数,甚至也可以修改本身由Docker所控制的内核级参数。 Operator exclusive options 当执行docker run时可以设定的资源如下:
