Helm in Practice

Managing Dependencies

Updating Dependencies

When developing your chart, you may need to introduce updates to dependencies. For example, to update the PostgreSQL version from 16.4.3 to 16.5.0, follow these steps:

1. Edit Chart.yaml and change the version:

dependencies:
  - name: postgresql
    version: "16.5.0"  # New version
    repository: "https://charts.bitnami.com/bitnami"

1. Update the lock file and download:

helm dependency update $HOME/todowithdb-chart

ℹ️ helm dependency update is different from helm dependency build. The former updates the Chart.lock file to reflect changes in Chart.yaml, while the latter simply downloads dependencies based on the existing Chart.lock.

1. Repackage and deploy:

# Increment your chart version in Chart.yaml (e.g., 0.1.1)
helm package $HOME/todowithdb-chart -d $HOME/todowithdb-chart-dist

helm push $HOME/todowithdb-chart-dist/todowithdb-chart-0.1.1.tgz \
  oci://$MASTER_PUBLIC_IP:30003/todo-app

Any change introduced to either Chart.yaml or values.yaml
