I need Docker Joomla image of version 2.15.4 about docker-joomla

[Hackwar]

The oldest Docker image we have is with Joomla 3.4. We don't have any images for Joomla 2.5.

Thanks for quick reply. I have installed Joomla using Docker image. Do you have any idea, how to downgrade Joomla to any older version or how to downgrade the php version of Joomla?

There is an unofficial way for you to get that kind of image.
Fork this repo, then in your fork open the https://github.com/joomla-docker/docker-joomla/blob/master/versions.json file and add the version details you would like to build.

Then run https://github.com/joomla-docker/docker-joomla/blob/master/update.sh in your repository.

This should build the Docker files for that version. Do note that you may need to tweak that docker file a little more since its aimed at Joomla 3.4 and above... then do a normal docker build on the docker file and you will have a local image.

This image will not get any support or other help from the official maintainers... but it will give you an image.

Also note that the lowest I have taken Joomla was 3.4 as @Hackwar stated. Here is where I play with Joomla and Docker...
