Chapter 5 ■ Using the Tectonic ConsoleFigure 5-2. Adding an A record for the public IP address of the controllerSSH log in to the controller instance and install kubectl as shown in Figure 5-3.Figure 5-3. SSH logging into the CoreOS controller instanceRun the following command to list the binaries.kubectl get nodes119
Chapter 5 ■ Using the Tectonic ConsoleThe single master node and the three worker nodes are listed, as shown in Figure 5-4.Figure 5-4. Listing the nodesTectonic provides the following services for applications deployed in a user's cluster: Tectonic Console,Tectonic Identity, Tectonic Support, Tectonic Wizard, and Tectonic Manager. Tectonic Console is a webmanagement console for a Kubernetes cluster. Tectonic Identity is for user management for services on aKubernetes cluster. Tectonic Support is the support from a team. Tectonic Wizard is the Tectonic installationand configuration wizard. Tectonic Manager is for management of the Tectonic services themselves.Tectonic is available at three subscription levels: Starter, Lab, and Enterprise. Starter includes justthe Tectonic Console and does not provide security (SSO) features; it is suitable as an initial starter level.Tectonic Lab includes the Tectonic Console with Quay Enterprise Basic but does not include securityfeatures. Tectonic Enterprise includes Tectonic Identity for Trusted Computing in addition to the TectonicConsole with Quay Enterprise Basic and is suitable for production. While the Lab and the Enterprise levelsare fee-based, the Starter is free. We shall use the Tectonic Starter subscription level in this chapter. TectonicStarter level does not authenticate users.Next, register for the Tectonic Starter account at https://tectonic.com/starter/.Downloading the Pull Secret and the Tectonic ConsoleManifestTectonic is mainly an infrastructure platform that enables enterprises to run containers with Kubernetesanywhere, securely and reliably. The Kubernetes cluster makes use of a Pull Secret to download the TectonicConsole image. The Pull Secret is a Kubernetes formatted file containing the credentials required todownload the Tectonic Console image. Click on Account Assets after creating a Tectonic Starter project andclick Download Kubernetes Secret for the Pull Secret file coreos-pull-secret.yml as shown in Figure 5-5.120
