Hey @Yongchan Hong, welcome to lakeFS and thank you for your questions 👋🏻. 1. We haven't tested lakeFS with argocd. Can you give some more information about the trouble you're running into? Any error messages appearing? 2. The S3 gateway domain is the way for lakeFS to "understand" that the request is an S3-compatible request. This is needed when you want to interact with lakeFS using S3 clients like AWS CLI, boto, etc. When getting a request, lakeFS will check its Host header, and if it matches the S3 gateway domain, the request will be handled by the lakeFS S3-gateway. For this to work, the 3 DNS records mentioned here need to resolve to your lakeFS installation. lakeFS will do the rest 🙂. Here is some more information. 3. Can you please share the lakeFS logs from when you are trying to create the repository. Also, what kind of permissions did you give lakeFS and how? Can you share the helm values.yaml you used for the installation? (omitting any sensitive information, of course)
