Enterprise Kubernetes, delivered

Tectonic ships with CoreOS's signature automated operations, runs multi-cloud, and is the fastest, most secure path to Kubernetes.

Installer assets bundle

All installs of Tectonic produce an assets.zip bundle used to bootstrap the cluster. Though this archive is used to create the initial components, it contains several useful assets for administrators concerned with cluster lifecycle.

Contents of assets.zip

  • A TLS client certificate, and accompanying kubeconfig, with root-level access to the cluster to bypass Tectonic Identity.
  • TLS assets used by Kubelets and control plane components.
  • Manifests for all Tectonic components.
  • Provider specific assets such as raw cloudconfig files.

Using assets.zip to troubleshoot Tectonic

The main use of these files is to troubleshoot failing components.

Troubleshooting authentication issues in Tectonic Identity

If Tectonic Identity has been misconfigured, the kubeconfig and manifests in assets.zip can be used to regain access and reset Identity to its default configuration.

unzip assets.zip
export KUBECONFIG=$PWD/assets/auth/kubeconfig
kubectl apply -f ./assets/tectonic/identity-config.yaml

Sensitive information in assets.zip

Administrators should take proper precautions to ensure these assets remain secure.
