class Template(TemplateBase)
Synchronous template builder for E2B sandboxes.

​
build

@staticmethod
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,
          **opts: Unpack[ApiParams]) -> 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 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,
    alias='my-python-env',
    cpu_count=2,
    memory_mb=1024
)

build_in_background

@staticmethod
def build_in_background(template: TemplateClass,
                        alias: str,
                        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 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
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,
    alias='my-python-env',
    cpu_count=2,
    memory_mb=1024
)

get_build_status

@staticmethod
def get_build_status(build_info: BuildInfo,
                     logs_offset: int = 0,
                     **opts: Unpack[ApiParams])
Get the status of a build. Arguments:
  • build_info: Build identifiers returned from build_in_background
  • logs_offset: Offset for fetching logs
Returns: TemplateBuild containing the build status and logs Example 
from e2b import Template

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

​
alias_exists

@staticmethod
def alias_exists(alias: str, **opts: Unpack[ApiParams]) -> bool
Check if a template with the given alias exists. Arguments:
  • alias: Template alias to check
Returns: True if the alias exists, False otherwise Example 
from e2b import Template

exists = Template.alias_exists('base')
if exists:
    print('Template exists!')

​
check_alias_exists

def check_alias_exists(client: AuthenticatedClient, alias: str) -> bool
Check if a template with the given alias exists. Arguments:
  • client - Authenticated API client
  • alias - Template alias to check
Returns: True if the alias exists, False otherwise
