ENTRYPOINT不会被运行的command覆盖，而CMD则会被覆盖如果在Dockerfile种同时写了ENTRYPOINT和CMD，并且CMD指令不是一个完整的可执行命令，那么CMD指定的内容将会作为ENTRYPOINT的参数；如果CMD是一个完整的指令，那么它们两个会互相覆盖，谁在最后谁生效 ENTRYPOINT ["<executeable>","<param1>","<param2>",...]/...
usesUser+executeCommand()+editFile()System+installDocker()+buildImage()+runContainer() 结论 以上就是如何以管理员权限执行Dockerfile的完整流程。通过遵循以上步骤,你可以在自己的开发环境中使用Docker,非常方便。同时,了解Dockerfile中的每一条指令的目的和作用也非常重要,这将有助于你更灵活地使用Docker。如果你...
RUN <command> RUN ["executable","param1","param2"] (RUN ["可执行文本","参数1","参数2"]) 指令会被解析为Json数组,因此必须用双引号。 实例: RUN echo hello RUN ["/bin/bash","-c","echo hello"] RUN <command> 默认会在shell终端中运行命令,即/bin/sh -c RUN ["","",""] 使用exec...
The RUN instruction will execute any commands to create a new layer on top of the current image. The added layer is used in the next step in the Dockerfile. RUN has two forms: # Shell form: RUN [OPTIONS] <command> ... # Exec form: RUN [OPTIONS] [ "<command>", ... ] ...
# Set the default command to execute # when creating a new container CMD service nginx start 保存dockfile。 使用Dockerfile自动构建Nginx容器 因为我们命令Docker用当前目录的Nginx的配置文件替换默认的配置文件,我们要保证这个新的配置文件存在。在Dockerfile存在的目录下,创建nginx.conf: ...
# execute command to compile nginx RUN ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-file-aio --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --...
ENTRYPOINT ["executable", "param1", "param2"] (exec form, preferred)ENTRYPOINT command param1 param2 (shell form) ONBUILD:子镜像继承父镜像,子镜像运行时,父镜像ONBUILD被触发。 RUNENTRYPOINT ONBUILD ④ ONBUILD测试 两个DockerFile文件:DockerFile3与DockerFile4。
SHELL ["powershell", "-command"] # 示例,比如在Windows时,默认shell是["CMD","/S","/C"] RUN powershell -command Execute-MyCmdlet -param1 "c:\foo.txt" # docker调用的是cmd /S /C powershell -command Execute-MyCmdlet -param1 "c:\foo.txt" ...
CMD command param1 param2 CMD ["param1", "param2"] RUN和CMD看起来挺像,但是CMD用来指定容器启动时用到的命令,只能有一条,如: CMD ["/bin/bash", "/usr/local/nginx/sbin/nginx", "-c", "/usr/local/nginx/conf/nginx.conf"] EXPOSE 格式:EXPOSE < port> [ < port >... ] ,如: EXPOSE...
ENTRYPOINT ["<executeable>","<param1>","<param2>",...] 第二种是官方推荐的使用方法,将命令分成几段,写成数组的形式;也可以像RUN一样写成shell的形式。 CMD <command> 或 CMD ["<executeable>","<param1>","<param2>",...] CMD ["<param1>","<param2>",...] ...
