Docker

Docker is the most widely used container runtime.

Prerequisites

Docker must be installed in your execution environment.

On macOS, mount your local /Users directory into the Docker virtual machine.

How it works

Enable Docker in the Nextflow configuration file:

docker.enabled = true
process.container = 'nextflow/examples:latest'

Whenever your pipeline launches a task, Nextflow runs it inside a Docker container created from the specified image using the docker run command.

You can also enable Docker on the command line:

nextflow run main.nf -with-docker

Advanced settings

See the docker configuration scope for advanced Docker settings.
