Advice on Deploying Harbor Registry in Active-Active Mode

[amitkumar2283]

TLDR:

Are there any recommended deployment patterns or best practices for deploying Harbor Registry in an active-active mode?

Long Read:

I'm reaching out to seek advice on deploying Harbor Registry in an active-active mode across multiple sites. Our goal is to ensure complete redundancy with each site having its own storage and database.

Our proposed architecture includes:

• Harbor Registry instances deployed in active-active mode across multiple sites
• Each site having its own storage (S3) and database
• Harbor instances behind a Load Balancer
• Bidirectional sync of storage (S3) to ensure images are synced across both Harbor instances

We're aware of potential challenges and would like to seek your advice on the following:

1. Unsynced DB data: Should we ensure that the databases are also in sync? If so, what's the recommended approach?
2. Robots and credentials: How can we ensure that robots and credentials created on one instance are synced with the other instance?
3. Caches: Are there any caching considerations we should be aware of in an active-active deployment?

We'd appreciate any guidance or advice you can offer.

Thank you for your time and expertise.
