## Common questions

### Should I still use the old localstack CLI?

No, the old localstack CLI is deprecated and no longer receives updates. Use the lstk CLI and migrate local scripts or CI workflows to it.

### How do I configure an AWS client to target LocalStack?

Add an AWS profile with dummy credentials and a region, such as ls-sandbox, and configure the client to use that profile. Missing credentials or a region can cause calls to fail.

### Can clients use the Kubernetes Service name for LocalStack?

Yes, but host-based access such as S3 virtual-host addressing will not work with the Service name. Verify the LocalStack DNS server is running if DNS resolution fails.

### Why can CI fail when pulling LocalStack images?

LocalStack moved its images behind authentication after archiving the public repository. CI must pull with a token, or the pull will fail.
