Running into an issue while using Gloo Mesh? Try the following debug guides and troubleshooting topics to find why things might not behave as expected. If you are still stuck, try posting on the Solo.io Slack.
General steps before debugging
- Make sure that you run a supported version of Gloo, Istio, and Kubernetes and their related command line interface (CLI) tools. If not, upgrade your version and CLIs.
- Review your infrastructure provider for any errors, incidents, or outages that might impact your clusters, load balancers, and related infrastructure. Common configuration problems happen in the following resources:
- Application load balancer (ALB) settings
- Expired or malformatted certificates, tokens, and secrets
Debug the Gloo setup: Troubleshoot issues by reviewing the Gloo server and agent statuses, snapshots, logs, and more.
Debug the gateway: Troubleshoot issues with the gateway and related resources, such as the backing load balancer.
Debug the Gloo UI graph: Debug the Gloo UI, such as if services do not show up in the Graph.
Debug the service mesh and apps: Debug Istio, Knative, and common service mesh apps like Bookinfo with Gloo observability tools.
