BioContainers in rkt Improve this page

rkt is a next-generation container manager for Linux clusters. Differently from the docker daemon, rkt is a single binary currently available on CoreOS and Kubernetes only, it’s designed for modern Linux clusters environments.

It is also possible to run Docker-based images with rkt. Since there is no signature verification, the only difference relies on the running sintaxe:

To reference a Docker image, use the docker:// prefix when fetching or running images.

> rkt --insecure-options=image run docker://biocontainers/comet

According to the original documentation :

This behaves similarly to the Docker client: if no specific registry is named, the Docker Hub is used by default. As with Docker, alternative registries can be used by specifying the registry as part of the image reference. For example, the following command will fetch an nginx Docker image hosted on

> rkt --insecure-options=image fetch docker://

Since the BioContainers images have no difference from traditional ones, you can use also use rkt to manage and execute the containers.
