Describe the enhancement you want to request

Description

Please create an official Docker sandbox template for OpenCode, similar to the existing one for Claude Code. This would enable a simple one-liner command: docker sandbox run opencode, which automatically launches OpenCode in the current project directory.

Why this feature?

• Proven with Claude Code: docker sandbox run claude already works seamlessly. It pulls a pre-configured template image from Docker Hub/registry, mounts the current working directory as the workspace, and ensures OpenCode only modifies files within that directory while keeping the host system completely isolated and untouched.

• ​Quick & Safe Usage: Developers can instantly use OpenCode from any project folder without manual Dockerfile creation, volume mounts, or security risks. The sandbox guarantees:

  • Exclusive file modifications in the mounted project dir

  • No access to host filesystem outside the workspace

  • Isolated network, processes, and credentials

• Parity with competitors: Claude Code users benefit from this native Docker AI integration; OpenCode as open-source deserves equivalent ease-of-use to boost adoption.

Implementation Notes

• Base on docker/sandbox-templates structure with OpenCode pre-installed (Go binary, auth setup, Git injection).
• Entry point auto-detects current dir and runs opencode .
• Publish to Docker Hub as docker/sandbox-opencode or similar.

This small addition would make OpenCode production-ready for secure, everyday use! Happy to test a POC.
