Overview

DigitalOcean provides a private Container Registry plus tools for managing Droplet images and snapshots.

Container Registry

Use Container Registry to store private container images.

• Create a registry in the target region.

• Authenticate build systems to push images.

• Configure App Platform or Kubernetes to pull from the registry.

Containers and Images

Use preconfigured images to create Droplets quickly.

• Select official or marketplace images when creating Droplets.

• Use snapshots to capture a configured Droplet as a reusable image.

Custom Images

Use custom images to boot Droplets with preinstalled stacks.

• Upload a custom image that meets DigitalOcean requirements.

• Use the custom image as the base for new Droplets.

Image Lifecycle Practices

• Standardize base images for consistency.

• Use snapshots to version and roll back Droplet states.

• Store container images in the registry alongside source commits.

Complementary Skills

When using this skill, consider these related skills (if deployed):

• digitalocean-compute: Droplets, App Platform, and Kubernetes compute selection.

• digitalocean-storage: Snapshots and backups.

• docker: Container build and runtime patterns.

Note: Complementary skills are optional. This skill is fully functional without them.
