Podman

Dagger can be used with any OCI-compatible container runtime, including Podman.

How it works

By default, Dagger tries to invoke the docker executable. Since Podman is CLI-compatible with Docker, it can be used as a drop-in replacement. This is as simple as creating a symbolic link to the Podman executable in your system path and naming it docker.

Prerequisites

Podman installed and running on the host system.
Podman machine configured for rootful container execution.

Example

To use Podman with Dagger, create a symbolic link as below:

shell

sudo ln -s $(which podman) /usr/local/bin/docker

:::note RHEL 8.x users may need to additionally execute modprobe iptable_nat. :::
