WSL: emulando docker e docker-compose com o podman

Estou usando o AlmaLinux 9 como distro do WSL, então os comandos abaixo são para o AlmaLinux.

sudo dnf install podman podman-docker
sudo touch /etc/containers/nodocker

O docker-compose precisa ser instalado em modo standalone.

sudo curl -SL https://github.com/docker/compose/releases/download/v2.20.3/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Habilite o systemctl no WSL

/etc/wsl.conf

[boot]
systemd=true

Execute no PowerShell para reiniciar a VM do WSL

wsl --shutdown

Abra o WSL novamente e habilite o systemctl

sudo systemctl enable --now podman.socket

Pronto.
