get docker images command's output with bash script

I'm trying to get the docker images command output to display it on a webpage.

Ex: Docker images ouput

As you can see on the image, this is well formatted.

But what I get on my web page is one line not formatted at all;

REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 3448f27c273f 2 days ago 109.4 MB mysql latest e799c7f9ae9c 3 days ago 407.3 MB

This my script at the moment; 

docker_images=$(docker images)

echo $docker_images

How can I get the well formatted output through my echo ?

Solution

  • So I tried an echo nl2br($output) which gave me this;

    HTML OUTPUT

    This is a bit better but still not well formatted. Any ideas how to improve this ?

    Edit :

    This is working now, i'm getting the output that I want. I juste had to do this;

    echo "<pre>";
echo nl2br($output) or $output;
echo "</pre>";

    Well it is in plain text. If anyone want to manipulate these, you can use the docker API. https://docs.docker.com/engine/api/v1.24/
