Telepresence is an open-source tool that allows developers to debug and develop services locally while connected to a remote Kubernetes cluster. It provides a seamless way to test code changes in real-time without the need to deploy them to the cluster, thus speeding up the development process.
When using Telepresence, you might encounter the error message: telepresence: error 18
. This error indicates that there is an issue with the authentication process, specifically related to the service account token.
Error 18 in Telepresence typically signifies that the service account token used for authentication with the Kubernetes cluster has expired. This token is crucial for establishing a secure connection between your local development environment and the remote cluster.
Service account tokens have a limited lifespan for security reasons. Once expired, they need to be renewed to maintain access to the Kubernetes cluster. If not renewed, Telepresence cannot authenticate, resulting in error 18.
To resolve this issue, you need to renew the service account token. Follow these steps:
kubectl create token --namespace=
telepresence quit
telepresence connect
After renewing the token and restarting Telepresence, verify that the issue is resolved by checking the connection status. You should no longer see error 18, and Telepresence should connect to the Kubernetes cluster successfully.
For more information on managing service accounts and tokens, refer to the official Kubernetes documentation on Service Accounts. Additionally, the Telepresence Documentation provides further insights into configuring and troubleshooting Telepresence.
