# 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。 2. 指令...
RUN /bin/bash -c 'source $HOME/.bashrc; echo $HOME RUN ["/bin/bash", "-c", "echo hello"] 注意:多行命令不要写多个RUN,原因是Dockerfile中每一个指令都会建立一层. RUN书写时的换行符是\ 多少个RUN就构建了多少层镜像,会造成镜像的臃肿、多层,不仅仅增加了构件部署的时间,还容易出错。 CMD 功...
指定使用其它终端可以通过第二种方式实现,例如使用bash终端: RUN [“/bin/bash”, “-c”, “echo hello”]。 注意:多行命令不要写多个RUN,原因是Dockerfile中每一个指令都会建立一层,多少个RUN就构建了多少层镜像,会造成镜像的臃肿、多层,不仅仅增加了构件部署的时间,还容易出错。一般一个RUN指令后边可以跟多...
RUN 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] ... # Exec form: RUN [OPTIONS] [ "", ... ] For more information...

Theexecform makes it possible to avoid shell string munging, and toRUNcommands using a base image that does not contain/bin/sh. Note: To use a different shell, other than '/bin/sh', use theexecform passing in the desired shell. For example,RUN ["/bin/bash", "-c", "echo hello"]...
