Nerdctl

Dagger can be used with any OCI-compatible container runtime, including nerdctl and finch (which uses nerdctl under the hood).

Prerequisites

Ensure that nerdctl (or finch) is installed and running on your system:

$ nerdctl info
Client:
 Namespace: default
 Debug Mode: false

warning

To be able to use the nerdctl backend as unprivileged user, nerdctl must be installed and running on the host system in rootless mode.

Using lima

To use nerdctl with Dagger via lima, create the following shell script at /usr/local/bin/nerdctl:

#!/bin/sh
lima nerdctl "$@"

Example

$ nerdctl ps
