$ docker run --name external-dns bitnami/external-dns:latestWhy use Bitnami Images?
- Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
- With Bitnami images the latest bug fixes and features are available as soon as possible.
- Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
- All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
- All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use
DOCKER_CONTENT_TRUST=1to verify the integrity of the images. - Bitnami container images are released daily with the latest distribution packages available.

How to deploy ExternalDNS in Kubernetes?
Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami ExternalDNS Chart GitHub repository.
Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.
Why use a non-root container?
Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.
