What this category of data looks like
This category of data is primarily sourced from LICENSE and NOTICE files in code repositories, third-party dependency lists, open-source contribution records, and license texts. Data updates are triggered with each version release or dependency change. The documentation structure includes three core file types: LICENSE declares overall project copyright and license terms, NOTICE lists copyright ownership and license information for third-party dependencies, and the dependency list marks component names, version numbers, and corresponding license types. Data fields include license type, copyright holder, dependency name, version number, and no additional statistical fields.
What constraints do these characteristics impose on deployment and upgrade workflows
Since this category of data updates frequently with version and dependency changes, ensure compliance documents fully match the dependency list of the currently deployed version during deployment to avoid compliance risks caused by version mismatches. Data sources rely on code repositories and dependency metadata APIs, so deployment configurations must support access to the corresponding metadata sources. During upgrades, sync and pull compliance information for new dependencies. Additionally, data involves copyright ownership and compatibility checks; deployments must configure metadata caching to improve check efficiency. Do not skip compliance validation steps for new dependencies during upgrades, otherwise compliance-related functions may fail after startup.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 connections | Controls the maximum number of connections in the database connection pool, matching the batch query load of compliance documents |
MONGODB_URI | mongodb://admin:your-mongo-pwd@mongo-host:27017/fastgpt?authSource=admin | Standard MongoDB connection format required for FastGPT v4.17.0, used to store compliance documents and system metadata |
REDIS_URL | redis://:your-redis-pwd@redis-host:6379/0 | Used to cache dependency license query results to reduce time spent on repeated checks |
STORAGE_S3_ENDPOINT | https://s3-cn-beijing.volces.com (or the root address of the selected storage provider) | Used to archive and store compliance documents for each version, enabling version rollback and auditing |
ROOT_KEY | Random 32+ character string with no special characters | Used to encrypt sensitive metadata of compliance documents to prevent unauthorized access |
Three Common Misconfigurations
- Symptom: FastGPT service fails to start with a database connection error, and compliance documents cannot be loaded. Cause:
MONGODB_URIis not configured correctly, the connection string lacks authentication information or the database name. - Symptom: After upgrading to FastGPT v4.17.0, the dependency license list cannot be updated automatically. Cause: The local dependency list file was not updated synchronously, and permission to pull dependency metadata was not configured during deployment.
- Symptom: Copyright notice content fails to load correctly on the frontend page. Cause:
FE_DOMAINis configured incorrectly, and the actual externally exposed domain name is not used, causing the compliance document access link to fail.
How to Verify Proper Configuration
- Run the service startup validation script to check that core configuration items such as
MONGODB_URIandREDIS_URLfollow the required format. - Manually trigger the dependency license pull task, and check the service logs for successful prompts about compliance document generation.
- Access the compliance notice section of the frontend page, confirm that links redirect correctly and the displayed copyright information matches the currently deployed version.
- Check the corresponding storage bucket for archived compliance document files matching the deployed version, to verify that storage configurations are working.
