Helm in Practice

Packaging and Distributing the Chart

If everything works as expected, we can package the chart using the helm package command, which creates a versioned chart archive file (.tgz). The syntax is as follows:

helm package [CHART_PATH] [FLAGS]

To package our todo-chart chart, we can run the following command:

helm package $HOME/todo-chart -d $HOME/todo-chart-dist

The version of the packaged chart is determined by the version field in the Chart.yaml file. However, you can change this by using the --version flag: helm package $HOME/todo-chart --version 0.2.0 -d $HOME/todo-chart-dist.

We can verify that the chart was packaged correctly by listing the contents of the output directory:

ls -lh $HOME/todo-chart-dist

Everything is ready to distribute the chart. We are using a private Harbor registry to host our Helm chart, so we need to log in to the registry first:

helm registry login $MASTER_PUBLIC_IP:30003 -u admin -p Harbor12345

Then, we can push the chart to the Harbor registry using the helm push command. The syntax is as follows:
