I started to used containerd instead of docker. I did what was to be installed for containerd with nerdctl. Nginx was the container I ran. Though container port 80 is mapped, it's not exposed. I've checked whether firewall blocks but none.
nerdctl run -d -p 80:80 70999c4a17c7
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0416dd502f86 docker.io/library/nginx:latest "/docker-entrypoint.…" 55 minutes ago Up 0.0.0.0:80->80/tcp nginx
So what could be the issue?
