# Commands when creating anewcontainer CMD/usr/sbin/nginx 其中,一开始必须指明所基于的镜像名称,接下来一般是说明维护者信息。后面则是镜像操作指令,例如 RUN 指令,RUN 指令将对镜像执行跟随的命令。每运行一条 RUN 指令,镜像就添加新的一层,并提交。最后是 CMD 指令,用来指定运行容器时的操作命令。
Split long or complexRUNstatements on multiple lines separated with backslashes to make yourDockerfilemore readable, understandable, and maintainable. 在多行上用反斜杠分隔长或复杂的RUN语句,以使您的Dockerfile更具可读性,可理解性和可维护性。 apt-get Probably the most common use-case forRUNis an app...
RUN Executes any commands in a new layer on top of the current image and commits the result.RUNalso has a shell form for running commands. WORKDIR <directory>Sets the working directory for anyRUN,CMD,ENTRYPOINT,COPY, andADDinstructions that follow it in the Dockerfile. COPY <src...

1. RUN 2. RUN ["executable", "param1", "param2"] 第一种后边直接跟shell命令 在linux操作系统上默认 /bin/sh -c 在windows操作系统上默认 cmd /S /C 第二种是类似于函数调用。 可将executable理解成为可执行文件,后面就是两个参数。 两种写法比对...
Docker Commands Docker Compose Docker Container 1. Overview Maintaining multiple containers with complex configurations can become difficult if we’re relying on the docker run command. Conveniently, Docker Compose provides a solution by enabling us to define multi-container Docker applications using a...
If you listmore than oneCMD, only the last one takes effect. So if you have multiple commands to run, you better write them in a script file. Docker is not the VMware, there is nosystemdin the container. Its startup program is the container application process. The container exists for...
run our build commands. I’ll first download the dependencies with go mod download, and I’ll go build to create the binary. And then finally, I’ll specify an entry point for my container, which is just going to say, this is the binary that’s going to get executed when you run ...
RUN 执行命令。 格式:#shell执行RUN #exec执行RUN ["executable", "param1", "param2"] 描述: 1)Dockerfile的指令每执行一次都会在docker上新建一层,所以尽量合并RUN。 2)exec执行格式是JSON数组,必须使用双引号描述。 3)exec格式不调用命令行shell,需要使用shell格式或者路径。如RUN [ "echo", "$...
