Summary

This PR upgrades the Ubuntu base image in the Dockerfile from version 18.04 to 22.04 (Jammy Jellyfish).

Changes Made

  • File Modified: Dockerfile
  • Change: Updated base image from ubuntu:18.04 to ubuntu:22.04

Rationale

  • Ubuntu 18.04 (Bionic Beaver) reached end of standard support in April 2023
  • Ubuntu 22.04 is a Long Term Support (LTS) release with support until April 2027
  • Using Ubuntu 22.04 provides:
    • Better security with more recent package versions
    • Access to updated dependencies and libraries
    • Improved performance and stability
    • Continued security patches and updates

Testing Considerations

  • Verify that all existing package installations (bash, curl, jq, ca-certificates) work correctly with Ubuntu 22.04
  • Ensure the entrypoint script functions as expected with the new base image
  • Test any workflows that depend on this Docker image

Files Modified

  • Dockerfile (line 1: changed base image version)

🤖 Generated with Claude Code

Updated the Dockerfile to use Ubuntu 22.04 as the base image instead of
the deprecated Ubuntu 18.04. This ensures we use a more recent and
supported Ubuntu LTS version for better security and package availability.
