Podman
Podman have more strict security settings than Docker, so you need to add more capabilities to the container to make it work properly. If your podman is not a rootless installation, you can use the default docker-compose.yml file, as the additional capabilities required by the container are already included in the default configuration.
Rootless Podman have more limitations. You can try to mount /dev/tun to avoid permission issues. Here is an example command to run the container with Podman:
podman run -d \
--name warp \
--restart always \
-p 1080:1080 \
-e WARP_SLEEP=2 \
--cap-add=NET_ADMIN \
--device=/dev/net/tun \
--sysctl net.ipv6.conf.all.disable_ipv6=0 \
--sysctl net.ipv4.conf.all.src_valid_mark=1 \
-v ./data:/var/lib/cloudflare-warp \
docker.io/caomingjun/warp:latest
I am not a Podman user, the example command is written by @tony-sung.
