Deploying Vote Result with ChartSource

Besides the Source as HelmRepository source we're also capable of deploying a HelmRelease with a GitRepository. Lets deploy the vote-result application with this technique:

Generate a helm chart for vote-result

First we need to install the helm CLI:

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

Now we can use the default template in the instavote repository:

cd instavote
mkdir -p deploy/charts && cd $_
helm create result

# A template for a Chart should be generated
ls -R result

Update the values to reflect the result-vote application

Update the settings for image.repository, image.tag and service.type

sed -i '' \
  -e 's@repository:.*@repository: schoolofdevops/vote-result@' \
  -e 's@tag:.*@tag: "latest"@' \
  -e 's@type: ClusterIP@type: NodePort@' \
  result/values.yaml

Commit and Expose the values:

git add result
git commit -m "feat: Add result chart definition"
git push origin HEAD:refs/heads/main
