build

@staticmethod
def build(template: TemplateClass,
          name: Optional[str] = None,
          *,
          alias: Optional[str] = None,
          tags: Optional[List[str]] = None,
          cpu_count: int = 2,
          memory_mb: int = 1024,
          skip_cache: bool = False,
          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 Template

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

Template.build(template, 'my-python-env:v1.0')

Template.build(template, 'my-python-env', tags=['v1.1.0', 'stable'])

                        **opts: Unpack[ApiParams]) -> BuildInfo
Build and deploy a template to E2B infrastructure without waiting for completion. 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
Returns: BuildInfo containing the template ID and build ID Example 
from e2b import Template

template = (
    Template()
    .from_python_image('3')
    .run_cmd('echo "test"')
    .set_start_cmd('echo "Hello"', 'sleep 1')
)

build_info = Template.build_in_background(template, 'my-python-env:v1.0')

build_info = Template.build_in_background(template, 'my-python-env', tags=['v1.1.0', 'stable'])
