Docker commands via php shell_exec

I’m trying run command from my index.php:

$output = shell_exec('docker images');

and then output results,

  • Registering an ELB to an ECS service with random host port
  • docker is not VM , why container need base image OS ? [closed]
  • How to link selenium server via docker compose
  • What to do about NPE when trying to build docker image using jenkins?
  • Jenkins run external script with docker command
  • Jenkins Pipeline push Docker image
  • or run new container the same way:

    $output = shell_exec('docker run hello-world');

    It seems that I could not run ANY docker cmd via php.

    How do it properly?

  • How to make changes to httpd.conf of apache running inside DOCKER container and restart apache
  • Docker: how to execute a batch file when container starts and keep the user in cmd / session
  • Play 2.5.x in Docker container not updating through shared folder
  • Errors with alpine linux 3.5 and ruby 2.0?

    You can do this:

    vi rd.php

    Put this content in rd.php file

    $output = shell_exec('RET=`docker run hello-world`;echo $RET');
    echo $output;

    Now you can run

    php rd.php

    You can view the result :

    Hello from Docker. This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (Assuming it was not already locally available.) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash For more examples and ideas, visit:

    That’s all !

    I hope this help you

    I did the following to get this working:

    1. Created a php file called index.php on /var/www/html/ with this content:

          echo '<pre>';
          $content = system('sudo docker images', $ret);
          echo '</pre>';
    2. Edited sudoers file with visudo, adding the following line at the end:

      www-data ALL=NOPASSWD: /usr/bin/docker
    3. Checked http://localhost/index.php and it worked!

    You can even build and run containers with this, hope it works for you.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
