So what would be the Helm equivalent in this case? With kubectl, we can use kubectl rollout status to further check the status of the deployment. It seems that the Helm chart deployments work similar to how kubectl apply works: the resources are created, but the actual deployment is not verified. $ helm delete -purge demo Wait and timeout However, the chart deployment history will show that the first deployment was superseded by the second one. Waiting for deployment "demo" rollout to finish: 1 old replicas are pending We can verify that the deployment didn’t finish successfully by viewing the deployment rollout status. The output shows that the chart was “deployed”, but the updated Pod wasn’t launched successfully. $ helm upgrade -install -set readinessPath=/fail demo demo/ĭemo-54df8f97bb-ffp4b 0/1 ContainerCreating 0 0s Let’s break the deployment on purpose by changing the path of the readiness probe to something that we know doesn’t work. When we create a failing deployment, we should see the same result. Helm didn’t check that our deployment finished successfully.

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGEĪs we can see from the output, the Helm chart was installed, but the deployment is still in progress.

Let’s use it to install the demo Helm chart we created earlier. With the upgrade feature, we can use a single command for installs and upgrades, which is handy for automation. The install sub-command always installs a brand new chart, while the upgrade sub-command can upgrade an existing chart and install a new one, if the chart hasn’t been installed before. There are two ways to install Helm charts using the Helm CLI: helm install and helm upgrade -install. Let’s parametrize the readiness probe, so that we can simulate a failing deployment by changing a Helm chart parameter. The template in path demo/templates/deployment.yaml generates the deployment manifest. This creates a simple chart in the directory demo/, which contains a deployment for a web server. Let’s generate a Helm chart to a local directory that we can use for testing failing and successful deployments. Each chart has their own set of variables that can be used for customizing the deployment.

The charts can be deployed from an external Helm repository, a chart archive file, or a local chart directory. In Helm, Kubernetes resources are distributed as charts: a collection of templated Kubernetes resources in YAML or JSON format.

We’ll be using Helm version 2.14.2 for the demonstration.

In this article, I’ll talk about how to repeat the deployment pattern demonstrated in the previous post using Helm.

One way to manage them safely is to use kubectl directly as demonstrated in my previous article.Īnother popular way to deploy resources to Kubernetes is to use Helm, a package manager for Kubernetes. The Deployment resource is the de-facto way to handle application deployments in Kubernetes, but there are many tools to manage them.
