What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)
Optimization of Dockerfile to reduce image size and improve build efficiency.
Why was this change needed? (You can also link to an open issue here)
This change aims to reduce Docker image size and enhance build efficiency. By merging apt-related RUN commands, we consolidate cleanup operations within the same layer, effectively reducing image size. Additionally, we removed the redundant apt-get clean command, as this operation is automatically handled in the Ubuntu base image.
Other information:
The reason why to remove
apt-get clean
is based on Docker's official best practices guide. More details can be found at:These changes not only reduce image size but also improve the efficiency of the build process, positively impacting continuous integration and deployment workflows.
