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:

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

note

Podman Desktop on Mac and RHEL 8.x users may need to additionally execute modprobe iptable_nat.

To access the virtual machine used by Podman Desktop on Mac, use the commands below:

# list podman machines
podman machine list 

# log in to machine
podman machine ssh podman-machine-default

# execute command
sudo modprobe iptable_nat
