Docker Mirrorv1.0.1

In a CI/CD pipeline (e.g., GitHub Actions, Jenkins) running on a Linux server with restricted internet access, Docker image pulls often fail from docker.io. This skill automatically retries with Chinese mirrors, ensuring pipeline stability without manual intervention.

Chinese universities or training institutes setting up Docker labs may face network timeouts when pulling images for courses (e.g., nginx, Redis). The tool simplifies image acquisition for students and instructors.

Individual developers in China using Docker for local development often encounter pull failures. This skill allows seamless image pulling for common tools like postgres, redis, or nginx.

Enterprises migrating workloads to or from air-gapped environments in China can use this tool to pre-pull images from accessible mirrors before transferring to restricted networks.

System administrators can periodically run docker.sh pull with test images (e.g., hello-world) to verify mirror availability and receive early warnings before failures impact production.

Offer a paid service that maintains a curated list of fast mirrors and provides a CLI tool (like this script) to enterprise clients, ensuring reliable image pulls in China.

Use the tool as part of Docker training packages for Chinese companies, offering workshops with hands-on labs that use this mirror-failover mechanism.

Keep the tool open-source but offer paid support SLAs for enterprises needing guaranteed mirror availability, custom mirror list configuration, and 24/7 incident response.
