                on_build_logs: Optional[Callable[[LogEntry], None]] = None,
                **opts: Unpack[ApiParams]) -> BuildInfo
Build and deploy a template to E2B infrastructure. Arguments:
  • template: The template to build
  • name: Template name in ‘name’ or ‘name:tag’ format
  • alias: (Deprecated) Alias name for the template. Use name instead.
  • tags: Optional additional tags to assign to the template
  • cpu_count: Number of CPUs allocated to the sandbox
  • memory_mb: Amount of memory in MB allocated to the sandbox
  • skip_cache: If True, forces a complete rebuild ignoring cache
  • on_build_logs: Callback function to receive build logs during the build process Example
from e2b import AsyncTemplate

template = (
    AsyncTemplate()
    .from_python_image('3')
    .copy('requirements.txt', '/home/user/')
    .run_cmd('pip install -r /home/user/requirements.txt')

                              **opts: Unpack[ApiParams]) -> BuildInfo
Build and deploy a template to E2B infrastructure without waiting for completion. Arguments:
