This PR introduces support for building and exporting Docker images designed specifically for air-gapped (closed-network) environments.
While the repository currently provides .deb installers for offline deployment, there is a growing demand for containerized deployments even in restricted environments for better orchestration and maintenance. This update bridge that gap by providing a native Docker-based offline workflow.
Changes:
New Dockerfile.offline: Uses requirements-full.txt instead of the standard requirements to pre-install all connector dependencies during the build stage.
.dockerignore Update: Modified to include requirements-full.txt in the build context so it can be accessed by the offline Dockerfile.
--offline Flag: Added to the build script to trigger the build using the offline-ready Dockerfile.
--save Flag: Added to allow users to export the built image directly into a .tar.gz archive, making it easy to transfer to servers without internet access.
Why this is needed:
In many enterprise or high-security production environments, direct internet access is prohibited. While .deb packages work, many modern infrastructures prefer Docker for consistency. These changes allow users to build a "heavy" image once in a networked environment and deploy it seamlessly in a fully offline environment.
