Building a Helm chart and managing it, are two different aspects of packaging an application for Kubernetes. Helm is efficient enough to package a complex K8s application and deploy it. When it comes down to app management, there are certain challenges with Helm. In this short blog, we will see how easy it is to deploy and manage a custom mongodb chart using Devtron.

So, let’s get started.

Note: The only prerequisite of getting started with Devtron is to have a Kubernetes cluster

Adding Helm repository

Devtron comes with a number of pre-added, commonly used Helm charts that can be seen in the `Charts` section. But if you want to install your custom chart, let's say MongoDB, it can be easily achieved using Devtron.

To add any custom chart, go to Global ConfigurationsChart RepositoryClick on Add RepositoryClick Save  → Click on Refresh Charts

Note: If you do not see any charts in Charts section, click on Refresh Charts to sync all the charts from added repositories

Deploying Helm charts

Now that we have added our custom chart repository i.e, percona, let’s deploy it.

To deploy any chart through Devtron, goto ChartsClick on Chart to DeployClick Deploy  → Change Values as per requiredClick Deploy Chart.

For instance, I want to deploy Percona's MongoDB operator. Let’s see how we can deploy it with just a few clicks.

Step-1: Select the chart to deploy i.e, percona/psmdb-operator

Step-2: Click on Deploy to edit default values as per your requirements

Step-4: Congratulations, you have successfully deployed! You can see all the details of your deployed chart such as current status, different workloads, manifests, events, logs, deployment history, etc within Devtron dashboard itself.
