Describe the bug
Unable to access docker. No images or containers are shown. Build in docker image not possible,

To Reproduce
Start eclipse 2025/03 binary, create new workspace. Window -> Show View ->Other -> Docker -> Docker Images. No docker images are shown, despite many do exist and Eclipse 2024/12 does show them.

In eclipse2025-workspace/.metadata/.log:

!ENTRY org.eclipse.linuxtools.docker.core 1 0 2025-03-12 19:35:16.919
!MESSAGE Failed to ping the Docker daemon for connection 'unix:///var/run/docker.sock'

Expected behavior
Docker should work and the images should show up.

This is a problem with Docker Tooling 5.18.0, not CDT. This release updates docker-client to 9.0 and there is a bug preventing communication with the docker connection. A work-around is to uninstall the Docker Tooling feature and reinstall the previous version from: https://download.eclipse.org/update-docker-5.17.0. A new issue has been opened against Linux Tools: eclipse-linuxtools/org.eclipse.linuxtools#461

Thank you for the quick response

[jjohnstn]

The problem was determined to be docker-client 9.0 not being able to work with httpclient5. A new version of docker-client has been made (9.0.3) which uses httpclient 4 and there is a maintenance release of Docker Tooling (5.18.1) which has just been made available through the https://download.eclipse.org/linuxtools/update-docker site. This site should be already be configured as part of the EPP and just needs to be enabled for an update to occur.

Tested, works. Thank you
