BytePlusCDN

Skill for BytePlus CDN domain and policy management, purge and prefetch, and log delivery. When you need to use BytePlus CDN acceleration services, you can refer to this skill's guide to complete CDN domain access, origin configuration, policy template, purge and prefetch, and offline/real-time log delivery tasks.

BytePlus CDN Skill

Installation and Configuration

Before using the BytePlus CDN Skill, please configure your environment following these steps.

1. Install Dependencies

Before using this skill, you need to install Python dependencies first. Please run the following command in the terminal:

bash

cd /path/to/byteplus-cdn
pip3 install -r reference/requirements.txt

2. Configure Authentication (Credentials)

Before executing any commands, you need to set the environment variables BYTEPLUS_AK and BYTEPLUS_SK for secure authentication. This is a prerequisite for calling BytePlus OpenAPI.

Security Best Practices:

• Create a .env file only in the project root directory
• Restrict BytePlus API keys to only the CDN permissions needed (least privilege principle)
• Never commit .env file to version control

You can create a .env file in the project root directory to store the AK and SK environment variables:

text

BYTEPLUS_AK=YourAccessKey
BYTEPLUS_SK=YourSecretKey

Windows PowerShell

powershell

$env:BYTEPLUS_AK="YourAccessKey"
$env:BYTEPLUS_SK="YourSecretKey"

Linux / macOS

bash

export BYTEPLUS_AK="YourAccessKey"
export BYTEPLUS_SK="YourSecretKey"

3. Verify Installation

After configuration, you can try running the CLI tool's help command to verify if the installation is successful:

bash

python3 scripts/cli.py --help

If the help information is successfully output, it indicates that the environment configuration is complete.

Feature Overview

This is a local command-line toolkit for operating BytePlus CDN, fully corresponding to all the instruction requirements in CLI.md. It includes the following core features:

1. Add CDN Domain - supports two methods:
   • Method 1: Directly configure the origin (supports Alibaba Cloud OSS, Tencent Cloud COS, AWS S3, BytePlus TOS, IP, Domain)
   • Method 2: Bind an existing distribution policy template
2. Create Policy Template - pre-configure and publish CDN distribution policies
3. Purge Cache - file refresh and directory refresh
4. Prefetch Cache - pre-load files from origin to CDN nodes
5. Create Offline/Real-time Log Delivery Tasks - configure log delivery destinations, supporting delivery to platforms like S3, BytePlus TOS, Splunk, etc.

✨ New Feature: Interactive Guide (Interactive Mode) If you run a command without any parameters (e.g., python3 scripts/cli.py add-domain oss), the CLI will guide you through the required parameters step by step like a wizard!

Agent Interaction Guidelines

When the Agent (AI) finds that it needs to collect missing parameters from the user, must follow these interaction specifications:

1. Option Type Parameters: Must use the AskUserQuestion tool to let the user make single or multiple selections (e.g., origin type, service type).
2. In-depth Understanding and Transparency of Underlying Prompts: Before calling AskUserQuestion to collect parameters, you must read the prompt and help definitions of the corresponding parameters in scripts/cli.py.
3. Construct Precise Collection Forms: In the collection form (AskUserQuestion) presented to the user, the description or options you provide must fully include the special prompts from cli.py! For example: if cli.py specifies that --domain can input "all" to represent all domains, you must provide a special ["All Domains (all)"] option in the form, and must not make up irrelevant test options yourself.
4. String Input Type Parameters: Except for special values supported by the underlying layer (such as all), always provide a ["Manual Input (Please select Other to input)"] option, allowing the user to evoke a friendly text input prompt via the system's own Other option.

Command List (Corresponding to CLI List)

The following examples all demonstrate usage in non-interactive mode (bringing all parameters at once). If you want to use interactive mode, simply omit the --xxx parameters.

1-6. Add CDN Domain (add-domain)

• Alibaba Cloud OSS (CLI 1)

  bash

  python3 scripts/cli.py add-domain oss --domain YOUR_DOMAIN_NAME --origin YOUR_BUCKET_NAME.YOUR_OSS_REGION.aliyuncs.com --service-type web --private-bucket yes --bucket-ak YOUR_AK --bucket-sk YOUR_SK --apply-recommended yes
  

• Tencent Cloud COS (CLI 2)

• AWS S3 (CLI 3)

  bash

  python3 scripts/cli.py add-domain aws --domain YOUR_DOMAIN_NAME --origin YOUR_BUCKET_NAME.s3.YOUR_AWS_REGION.amazonaws.com --service-type video --private-bucket yes --bucket-ak YOUR_AK --bucket-sk YOUR_SK --region YOUR_AWS_REGION --apply-recommended yes
  

• BytePlus TOS (CLI 4)

  bash

  python3 scripts/cli.py add-domain tos --domain YOUR_DOMAIN_NAME --origin YOUR_BUCKET_NAME.YOUR_TOS_REGION.bytepluses.com --service-type web --private-bucket yes --apply-recommended yes
  

• IP Origin (CLI 5)

  bash

  python3 scripts/cli.py add-domain ip --domain YOUR_DOMAIN_NAME --origin YOUR_IP_ADDRESS --service-type web --apply-recommended yes
  

• Domain Origin (CLI 6)

  bash

  python3 scripts/cli.py add-domain domain --domain YOUR_DOMAIN_NAME --origin YOUR_ORIGIN_DOMAIN --service-type web --apply-recommended yes
  

• Bind Policy Template - add a domain by binding a published distribution policy

  bash

  # Basic Usage
  python3 scripts/cli.py add-domain template --domain YOUR_DOMAIN_NAME --service-template-id tpl-s2Q4mq
  
  # Enable HTTPS
  python3 scripts/cli.py add-domain template --domain YOUR_DOMAIN_NAME --service-template-id tpl-s2Q4mq --https-switch on --cert-id cert-044833503b2349b4b42c2e80b0aa8c23
  
  # Full Usage (including cipher policy and rule engine policy)
  python3 scripts/cli.py add-domain template --domain YOUR_DOMAIN_NAME,img.YOUR_DOMAIN_NAME --service-template-id tpl-s2Q4mq --cipher-template-id tpl-cqgRvW --https-switch on --cert-id cert-044833503b2349b4b42c2e80b0aa8c23 --rule-template-ids tpl-re9gvl6,tpl-abc123

  bash

  python3 scripts/cli.py log-offline s3 --bucket YOUR_BUCKET_NAME/logs --domain YOUR_DOMAIN_NAME --endpoint YOUR_S3_ENDPOINT --region YOUR_AWS_REGION --private-bucket yes --ak YOUR_AK --sk YOUR_SK
  

16. Create Real-time Log Delivery Task (log-realtime)

Deliver real-time logs of domains to external systems (TLS, SLS, HttpServer, Splunk, BigQuery).

• Deliver to TLS

  bash

  python3 scripts/cli.py log-realtime tls --domain YOUR_DOMAIN_NAME --project-id YOUR_PROJECT_ID --region HongKong --topic-name YOUR_TOPIC_NAME --ttl 30
  

• Deliver to SLS

  bash

  python3 scripts/cli.py log-realtime sls --domain YOUR_DOMAIN_NAME --sls-endpoint YOUR_SLS_ENDPOINT --project YOUR_PROJECT_NAME --log-store YOUR_LOG_STORE --ak YOUR_AK --sk YOUR_SK

• Deliver to Splunk

  bash

  python3 scripts/cli.py log-realtime splunk --domain YOUR_DOMAIN_NAME --url https://splunk.YOUR_DOMAIN_NAME:8088/services/collector/event --token YOUR_TOKEN
  

• Deliver to BigQuery

  bash

  # Method 1: Pass JSON string directly
  python3 scripts/cli.py log-realtime bigquery --domain YOUR_DOMAIN_NAME --project-id YOUR_GCP_PROJECT_ID --dataset-id YOUR_DATASET_ID --table-id YOUR_TABLE_ID --auth-str '{"type":"service_account",...}'
  
  # Method 2 (Recommended): Pass JSON via local file (CLI will automatically read and escape)
  python3 scripts/cli.py log-realtime bigquery --domain YOUR_DOMAIN_NAME --project-id YOUR_GCP_PROJECT_ID --dataset-id YOUR_DATASET_ID --table-id YOUR_TABLE_ID --auth-file /path/to/gcp-auth.json
  

Recommended Configuration Description (Only applicable to add-domain and create-template)
