Environment Characteristics

​
Isolation and Security

The Tembo Sandbox operates in a containerized Docker environment that provides:
  • Process isolation: Each task runs in its own isolated container
  • File system isolation: Changes are contained within the sandbox
  • Network security: Controlled network access for security
  • Resource limits: CPU and memory constraints to ensure stability

​
Development Workflow Integration

The sandbox environment is designed to integrate seamlessly with your development workflow:
  • Hook support: Execute custom commands at different stages via Tembo Hooks
  • Repository access: Full access to your repository contents and history
  • Build tool compatibility: Support for common build systems and package managers
  • Testing frameworks: Compatible with popular testing tools and frameworks

​
Best Practices

When working with the Tembo Sandbox environment:

​
Dependency Management

  • Use existing tools: Leverage the pre-installed package managers and tools when possible
  • Specify versions: When installing additional dependencies, pin to specific versions for reproducibility
  • Cache efficiently: Use package manager caching features to improve build times

​
Resource Optimization

  • Minimize installations: Avoid installing large dependencies unless necessary
  • Clean up: Remove temporary files and build artifacts when possible
  • Use lightweight alternatives: Choose lighter-weight tools when multiple options are available

​
Compatibility Considerations

  • Version awareness: Be aware of the pre-installed tool versions when writing build scripts
  • Cross-language support: Take advantage of the multi-language environment for polyglot projects
  • Tool conflicts: Be mindful of potential conflicts between different language ecosystems

​
Support and Updates

The Tembo Sandbox environment is regularly updated to include:
  • Security patches for all installed tools
  • Updates to major language runtimes and package managers
  • New tools based on community feedback and usage patterns
If you need a specific tool or version that isn’t currently available, please reach out to the Tembo team through your dashboard or contact support.
