Using the Ubuntu image, after installing Apache2, you need to start Aapche2 as the container starts.

You can't start with the container if you try to modify it in / etc/rc before.

Then write the startup to CMD ["service", "apache2", "start"], and the container cannot be started (because it exits the container after execution) ~

You have to write a self-startup script for apache2 in the container, and then run the script when you start the container, as follows:

# the / bin/bash in the container # vim / ETC _ Apache _ apache2 _ auto _ bin/bash service.shrub _ torque _ bind _ service _ service apache2 start / bin/bash is to keep a terminal, so that the execution will not end. # chmod 777 / etc/apache2/auto_service.sh encapsulates the container with self-startup script as an image # on the server # docker commit demo ubuntu#vim DockerfileFrom demoCMD ["/ bin/sh", "/ etc/apache2/auto_service.sh"] build a new image based on Dockerfile # docker buitd-t auto_apahce2.

After that, use auto_apache2 to image the started container, and then you can start apache2~ automatically.

Of course, you can also write all the steps of self-startup script into Dockerfile:

Dockerfile content

From ubuntu_demoRUN echo-e'#! / bin/sh\ nservice apache2 start\ nbind etc/apache2/auto_service.sh bash'> / etc/apahce2/auto_service.sh & &\ chmod 777 / etc/apache2/auto_service.sh & &\ CMD ["/ bin/sh", "/ etc/apache2/auto_service.sh"]

Generate an image based on Dockerfile

# docker build-t auto_service_ubuntu.
