Quickstart

Push and pull files to an OCI registry in under 5 minutes.

Prerequisites

• blobber installed
• Access to an OCI registry (GitHub Container Registry, Docker Hub, etc.)
• Docker credentials configured (docker login)

1. Create Test Files

Create a directory with some files to push:

mkdir myconfig
echo "database: postgres://localhost:5432/mydb" > myconfig/database.yaml
echo "port: 8080" > myconfig/server.yaml
echo "log_level: info" > myconfig/logging.yaml

2. Push to Registry

Push the directory to your registry:

blobber push ./myconfig ghcr.io/YOUR_USERNAME/config:v1

Output:

sha256:a1b2c3d4e5f6...

The SHA256 digest confirms your files are stored.

3. List Remote Files

See what's in the image without downloading:

blobber list ghcr.io/YOUR_USERNAME/config:v1

Output:

database.yaml
logging.yaml
server.yaml

4. Stream a Single File

View a specific file without pulling everything:

blobber cat ghcr.io/YOUR_USERNAME/config:v1 database.yaml

Output:

database: postgres://localhost:5432/mydb

5. Pull All Files

Download everything to a local directory:

blobber pull ghcr.io/YOUR_USERNAME/config:v1 ./downloaded

Verify the files:

ls ./downloaded

Output:

database.yaml  logging.yaml  server.yaml
