Create helm chart with the following command.
58+
59+
```sh
60+
helm create deployment
61+
```
62+
63+
Then, edit the deployment file, service and config map file accordingly.
64+
65+
After editing all configuration files, install with helm.
66+
67+
```sh
68+
helm install compare-helm deployment
69+
```
70+
71+
Helm will create k8s components based on the configuration files. Use `kubectl get all | grep helm` to find them.
72+
73+
```sh
74+
kubectl get all | grep helm

# A chart can be either an 'application' or a 'library' chart.

# Application charts are a collection of templates that can be packaged into versioned archives

10+
# Library charts provide useful utilities or functions for the chart developer. They're included as
11+
# a dependency of application charts to inject those utilities and functions into the rendering
12+
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
