[Helm Chart] InfraStack Charts: A Comprehensive Guide to Creating and Verifying Multiple Charts

In the world of Kubernetes and Helm, creating and managing multiple charts can be a daunting task. However, with the right tools and scripts, it can be a breeze. In this article, we will explore the process of creating multiple Helm charts in the ekp-helm repository using the ekp-chart.sh script and then applying fixes and verifications.

Understanding the Charts to Create

Before we dive into the process, let's take a look at the charts that need to be created:

  • nginx-ingress
  • projectsveltos
  • rancher
  • vcluster
  • flux
  • contour
  • keda
  • crossplane
  • knative
  • kong
  • falco
  • thanos

Each of these charts has its own unique requirements and dependencies, which we will need to take into account as we create them.

Step 1: Generate Each Chart

To create each chart, we will use the ekp-chart.sh script. This script takes several parameters, including:

  • --name: The name of the chart to create
  • --dependency-url: The URL of the dependency chart
  • --dependency-chart-name: The name of the dependency chart
  • --dependency-chart-version: The version of the dependency chart
  • --dependency-alias: An optional alias for the dependency chart (in CamelCase)

Here is an example of how to run the script for each chart:

./ekp-chart.sh create --name nginx-ingress \
  --dependency-url https://example.com/nginx-ingress \
  --dependency-chart-name nginx-ingress \
  --dependency-chart-version 1.2.3 \
  --dependency-alias nginxIngress

Note that if the chart name has multiple words, we need to provide an alias in CamelCase using the --dependency-alias parameter.

Step 2: Fix Lint Issues

After creating each chart, we need to run the fix-lint.sh script to fix any linting issues within the generated chart files. This script will report any errors or warnings and provide suggestions for fixing them.

Here is an example of how to run the script:

./fix-lint.sh

Step 3: Verification

Once we have created and linted each chart, we need to run the link.sh script to perform link checks and validations. This script will ensure that the newly created charts pass all required verifications.

Here is an example of how to run the script:

./link.sh

Step 4: Push to Repository

Once all charts are successfully created, linted, and verified, we can commit and push them to the ekp-helm repository.

Definition of Done

To confirm that the process is complete, we need to verify that:

  • Each of the listed charts has been created with the correct dependency-url, dependency-chart-name, dependency-chart-version, and optional alias.
  • fix-lint.sh runs without errors for each chart.
  • link.sh passes successfully, confirming all links and references are valid.
  • The new charts are committed to the repository in a consistent folder structure.

By following these steps and verifying the results, we can ensure that our Helm charts are created and managed correctly, and that our infrastructure is running smoothly.

Conclusion

Creating and managing multiple Helm charts can be a complex task, but with the right tools and scripts, it can be a breeze. By following the steps outlined in this article, we can create and verify multiple charts in the ekp-helm repository, and ensure that our infrastructure is running smoothly. Whether you are a seasoned DevOps engineer or just starting out, this guide provides a comprehensive overview of the process and helps you to get started with creating and managing Helm charts.
[Helm Chart] InfraStack Charts: Frequently Asked Questions

In our previous article, we explored the process of creating and verifying multiple Helm charts in the ekp-helm repository using the ekp-chart.sh script.

Q: What is the purpose of the ekp-chart.sh script?

A: The ekp-chart.sh script is a tool that helps you create Helm charts in the ekp-helm repository. It takes several parameters, including the chart name, dependency URL, dependency chart name, dependency chart version, and optional alias.

Q: How do I run the ekp-chart.sh script?

A: To run the ekp-chart.sh script, you need to provide the required parameters, such as the chart name, dependency URL, dependency chart name, dependency chart version, and optional alias. You can do this by running the following command:

./ekp-chart.sh create --name <chartName> \
  --dependency-url <url> \
  --dependency-chart-name <depChartName> \
  --dependency-chart-version <depChartVersion> \
  [--dependency-alias <alias>]

Q: How do I run the link.sh script?

A: To run the link.sh script, you simply need to run the following command:

./link.sh

Q: What is the definition of done for creating and verifying Helm charts?

A: The definition of done for creating and verifying Helm charts includes the following:

  • Each of the listed charts has been created with the correct dependency-url, dependency-chart-name, dependency-chart-version, and optional alias.
  • fix-lint.sh runs without errors for each chart.
  • link.sh passes successfully, confirming all links and references are valid.
  • The new charts are committed to the repository in a consistent folder structure.

Q: How do I commit and push the new charts to the ekp-helm repository?

A: Once all charts are successfully created, linted, and verified, you can commit and push them to the ekp-helm repository using the following commands:

git add .
git commit -m "Added new charts"
git push origin master

Q: What if I encounter errors or issues during the process?

A: If you encounter errors or issues during the process, you can refer to the ekp-helm repository documentation or reach out to the community for support. Additionally, you can also use the fix-lint.sh script to fix any linting issues within the generated chart files.
