Installing a Chart

As we have seen, the general syntax for installing a chart is:

helm install [RELEASE_NAME] [CHART] [flags]

Let's see different examples:

Installing from a Specific Repository

helm install my-release myrepo/mychart

Using a Chart with a Custom Configuration

helm \
  install \
  my-release \
  myrepo/mychart \
  --set service.type=NodePort

Using a Chart with Custom Configurations

helm \
  install \
  my-release \
  myrepo/mychart \
  --set service.type=NodePort \
  --set service.nodePort=30080

Using a Chart with a Custom Configuration File (values.yaml)

As an alternative to the --set flag, it's simpler to use the --values flag to specify a custom configuration file, especially when you have multiple configurations to set.

helm \
  install \
  my-release \
  myrepo/mychart \
  --values values.yaml

Installing a Chart from a Local Directory

The ./chart-directory should exist and contain a valid Helm chart structure.

helm \
  install \
  my-release \
  ./chart-directory

Installing a Chart from a Local Repository with a Custom Configuration File (values.yaml)

helm \
  install \
  my-release \
  ./chart-directory \
  --values values.yaml
