We will leave the delay set to 1 minute and turn off the reboot. We will be doing a state Chaos Engineering Attack, so select “State” and choose “Shutdown” from the options. We will now go over to choosing the Gremlin. We can find the container we want to target by expanding the Deployments field and selecting "cartservice". Gremlin has imported the objects from Kubernetes and we can see them in the UI. We will be shutting down the “cartservice” containers. We’re going to target a Kubernetes resource, so click on the Infrastructure tab, then click on Kubernetes in the upper right.
Going back to the Gremlin UI, select Attacks from the menu on the left and press the blue “New Attack” button. I expect that my application’s cart will be replaced by Kubernetes after it is shutdown”. Our hypothesis is, “When shutting down my cart service container, my entire application will not suffer downtime and existing data in my cart will not be lost since it’s stored in Redis. We want to validate our application’s reliability. We are going to start practicing Chaos Engineering by creating our first Gremlin Scenario. Step 9 - Run a Gremlin Scenario to validate reliability Now visit localhost in your browser to view the Hipster Shop:
Open Terminal (Mac/Linux) or Command Prompt (Windows) and check that your Kubernetes cluster is up and running by typing: Step 2 - Verify your Kubernetes cluster is up and running If you break your cluster or do something wrong, the fastest way to get back to a clean slate is to just click that button. Note: the Reset Kubernetes Cluster button within Preferences is very handy. If you've used Docker Desktop before, make sure to select the correct Kubernetes context: click on the Docker Desktop icon in the menu bar, then select Kubernetes > docker-desktop.Īdvanced: You can also set your context via the command line using kubectl. Once Kubernetes is up and running, you'll get a green light and it will say " Kubernetes is running". Click "Apply & Restart" to finish the installation. Next, click on preferences within the Docker Desktop main menu, select Kubernetes, then click Enable Kubernetes. First, you'll need to sign in or create a Docker ID. You'll see a little Docker icon (whale) in your menu bar.
