E2B Workarounds

Since E2B SDK need HTTPS and Wildcard Domain support for sandbox routing, if your environment doesn't support these features, you can use the following workarounds to adapt to your environment.

E2B default sandbox URL format is as follows:
https://{port}-{sandboxID}.your-domain.com

e.g.
https://6080-294bef011f1e4567b4c5d02593e2e90e.example.com

‼️ If you don't have https or Wildcard Domain(*.example.com) support, please config and hack by the following functions no_wildcard() to adapt to your environment.

import os

def no_wildcard():
    os.environ['E2B_API_URL'] = 'http://localhost:10000/e2b/v1'
    os.environ['E2B_API_KEY'] = 'testuser-aef134ef-7aa1-945e-9399-7df9a4ad0c3f'
    os.environ['E2B_DOMAIN'] = 'localhost:10000'

    def __connection_config_get_host(_, sandbox_id: str, sandbox_domain: str, port: int) -> str:
        return f"{sandbox_domain}/sandboxes/router/{sandbox_id}/{port}"
    from e2b import ConnectionConfig
    ConnectionConfig.get_host = __connection_config_get_host

No HTTPS

os.environ['E2B_DEBUG'] = "true" will use HTTP for API requests, which is useful for local development without HTTPS.

Kubernetes Ingress Configuration for Wildcard Domain

You can set the following environment variables to configure E2B SDK:

import os
os.environ['E2B_DOMAIN'] = 'example.domain.com'
os.environ['E2B_API_URL'] = 'https://example.domain.com/e2b/v1'
os.environ['E2B_API_KEY'] = 'testuser-aef134ef-7aa1-945e-9399-7df9a4ad0c3f'

Agent-Sandbox ingress should also be configured to support wildcard domain.
