Container Manager
Registries
Authenticate to Docker Hub and private image registries.
Docker Hub and private registry credentials.
Purpose
Registries (act=podman_registries) store credentials used when pulling private images or authenticating to mirrors.
Common registries
- Docker Hub (often pre-listed)
- GitHub Container Registry, GitLab, Quay, Harbor, or other private registries
Add or edit a registry
- Open Registries
- Add registry URL / identity details
- Save credentials
- Use Test when available to verify connectivity
Using registries in deploys
When composing a service, choose the registry/image that needs auth. Failed pulls almost always mean wrong credentials, wrong image path, or network restrictions.
Treat credentials as secrets
Use least-privilege tokens. Rotate them if a machine or teammate access changes.
