An HTTP-triggered function runs in the image environment built in it based on the standard programming language. You must create an executable file scf_bootstrap
to start your web server, and then package the file with your code files for deployment to create an HTTP-triggered function. During actual request processing, your web server will receive HTTP requests by listening on the specified 9000
port, forward them to the backend service for logic processing, and return the responses to end users.
scf_bootstrap
is the bootstrap file of your web server and ensures that your web service can normally start and listen on requests. In addition, you can customize scf_bootstrap
to implement more personalized operations as needed:
/tmp
directory.Note:
- SCF only supports reading scf_bootstrap as the bootstrap file name, and other names cannot start the service normally.
- In the Tencent Cloud standard environment, only the
/tmp
directory is readable and writable. When outputting files, select the/tmp
path; otherwise, the service will exit abnormally due to the lack of write permission.
scf_bootstrap
file has the 777 or 755 permission; otherwise, it cannot be executed due to insufficient permissions.#!/bin/bash
in the first line./var/lang/${specific_lang}${version}/bin/${specific_lang}
; otherwise, it cannot be invoked normally. For more information, see Absolute Paths in Standard Language Environments.0.0.0.0
, and the internal loopback address 127.0.0.1
cannot be used.You can write your scf_bootstrap
file locally, make sure that the file permission meets the requirements, package it with the project code, and deploy them together on the HTTP-triggered function.
After the deployment is completed, you can view and edit the scf_bootstrap
file in the code editor as shown below:
Run the scf_bootstrap
file as the container bootstrap command. You must ensure that the container can normally start and run the code logic. Therefore, make sure that your bootstrap command is written correctly. If you encounter a 405
error code, it is usually caused by the failure to run the file; therefore, also make sure that your bootstrap file is written correctly.
