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.
