Kubo Overview

Secure your stack with a hardened Kubo image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Kubo is the original and most widely used implementation of IPFS, a peer-to-peer protocol for storing and sharing content-addressed data across a distributed network of nodes.

Try It Out

Start the Kubo Daemon

Create local directories for the node's repository and for files you want to add to IPFS:

mkdir -p ipfs-staging ipfs-data

Run the daemon, mounting both directories and publishing the swarm, API, and gateway ports:

docker run -d --name kubo \
  -v "$(pwd)/ipfs-staging:/export" \
  -v "$(pwd)/ipfs-data:/data/ipfs" \
  -p 4001:4001 -p 4001:4001/udp \
  -p 127.0.0.1:5001:5001 -p 127.0.0.1:8080:8080 \
  reg.mini.dev/kubo

Confirm the node has finished initializing:

docker logs kubo

You should see Daemon is ready.

Add and Retrieve a File

Add a file to the staging directory, then add it to IPFS from inside the running container:

echo "Hello from Minimus" > ipfs-staging/hello.txt
docker exec kubo ipfs add /export/hello.txt

added QmXybYq1p3aiJqAJP9LXTBd8j9VBFxa8jZWSjhQdG4hS7X hello.txt

Retrieve the file back by its CID:

docker exec kubo ipfs cat QmXybYq1p3aiJqAJP9LXTBd8j9VBFxa8jZWSjhQdG4hS7X

The content is also reachable through the local HTTP gateway:

curl http://127.0.0.1:8080/ipfs/QmXybYq1p3aiJqAJP9LXTBd8j9VBFxa8jZWSjhQdG4hS7X

Clean Up

docker rm -f kubo

Technical Considerations

The Kubo image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

Kubo built by Minimus:

Runs as root to support required functions in alignment with the public image.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
