你也可以将多个命令写入一个shell脚本文件中,然后在Dockerfile中指定该脚本作为ENTRYPOINT或CMD。 startup.sh: bash #!/bin/bash echo "Running multiple commands" command1 command2 command3 exec "$@" Dockerfile: dockerfile FROM ubuntu:20.04 COPY startup.sh /app/startup.sh RUN chmod +x /app/star...

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。 1.4 Dockerfile 指令清单 1.4.1 FROM 指定所创建镜像的基础镜像,...
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. ...
$ docker run -P nginx:alpine The -P, or --publish-all, flag publishes all the exposed ports to the host. Docker binds each exposed port to a random port on the host. The -P flag only publishes port numbers that are explicitly flagged as exposed, either using the Dockerfile EXPOSE ...
Run multiple processes in a container Page options A container's main running process is the ENTRYPOINT and/or CMD at the end of the Dockerfile. It's best practice to separate areas of concern by using one service per container. That service may fork into multiple processes (for example...
Dockerfile常用指令 一、Dockerfile Docker可以通过Dockerfile自动构建镜像,Dockerfile是一个包含多个指令的文档。如下 # syntax=docker/dockerfile:1 FROM ubuntu:18.04 COPY . /app RUN make /app CMD python /app/app.py 二、FROM FROM命令用于初始化一个新的构建阶段,并为后续指令设置基础镜像: FROM [-...
1. RUN指令 这个指令是dockerfile里用的最多的指令之一,它的作用就是执行一条命令。类似于linux的shell脚本里的命令一样,写一个RUN,后面跟着命令就执行一次。 比如上面的那个示例dockerfile里,就有那么一段关于RUN命令的集合: 代码语言:javascript 代码运行次数:0 ...
