class AsyncTemplate(TemplateBase)
Asynchronous template builder for E2B sandboxes.

build

@staticmethod
async def build(template: TemplateClass,
                alias: str,
                cpu_count: int = 2,
                memory_mb: int = 1024,
                skip_cache: bool = False,
                on_build_logs: Optional[Callable[[LogEntry], None]] = None,
                api_key: Optional[str] = None,
                domain: Optional[str] = None) -> BuildInfo
Build and deploy a template to E2B infrastructure. Arguments:
  • template: The template to build
  • alias: Alias name for 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
  • api_key: E2B API key for authentication
  • domain: Domain of the E2B API 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')
)

await AsyncTemplate.build(
    template,
    alias='my-python-env',
    cpu_count=2,
    memory_mb=1024
)

                              alias: str,
                              cpu_count: int = 2,
                              memory_mb: int = 1024,
                              skip_cache: bool = False,

                                                               None]] = None,

                              domain: Optional[str] = None) -> BuildInfo
Build and deploy a template to E2B infrastructure without waiting for completion. Arguments:
  • template: The template to build
  • alias: Alias name for 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
  • api_key: E2B API key for authentication
  • domain: Domain of the E2B API
Returns: BuildInfo containing the template ID and build ID Example 
from e2b import AsyncTemplate

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

build_info = await AsyncTemplate.build_in_background(
    template,
    alias='my-python-env',
    cpu_count=2,
    memory_mb=1024
)

get_build_status

@staticmethod
async def get_build_status(build_info: BuildInfo,
                           logs_offset: int = 0,
                           api_key: Optional[str] = None,
                           domain: Optional[str] = None)
Get the status of a build. Arguments:
  • build_info: Build identifiers returned from build_in_background
  • logs_offset: Offset for fetching logs
  • api_key: E2B API key for authentication
  • domain: Domain of the E2B API
Returns: TemplateBuild containing the build status and logs Example 
from e2b import AsyncTemplate

build_info = await AsyncTemplate.build_in_background(template, alias='my-template')
status = await AsyncTemplate.get_build_status(build_info, logs_offset=0)
