I supposedly installed the latest podman, only a week ago - but for the Pi Zero W's 32-bit ARMv6. Everyone seems to provide v6 versions of things, and they seem to install, but I'm getting more and more convinced that they just don't work. pi@raspberrypi:~/tripod $ podman logs 787779b20e96 pi@raspberrypi:~/tripod $ podman logs 54a005199e38 pi@raspberrypi:~/tripod $ podman logs httpd Error: no container with name or ID httpd found: no such container pi@raspberrypi:~/tripod $ podman logs docker.io/library/httpd Error: no container with name or ID docker.io/library/httpd found: no such container pi@raspberrypi:~/tripod $ So the ID numbers don't show errors, the names do. Not sure what that means... But seems there are no logs. I suspect since the run ends in under two seconds, there really aren't any logs. Where would the logs be stored in my filesystem? Would the names include "podman"? Searching for logs, I saw: pi@raspberrypi:~ $ cat /etc/cni/net.d/87-podman-ptp.conflist { "cniVersion": "0.4.0", "name": "podman", "plugins": [ { "type": "ptp", "Documentation": "/usr/share/doc/containernetworking-plugins/main_ptp.md", "ipMasq": true, "ipam": { "type": "host-local", "Documentation": "/usr/share/doc/containernetworking-plugins/ipam_host-local.md", "subnet": "172.16.16.0/24", "routes": [ { "dst": "0.0.0.0/0" } ] } }, { "type": "portmap", "Documentation": "/usr/share/doc/containernetworking-plugins/meta_portmap.md", "capabilities": { "portMappings": true } }, { "type": "firewall", "Documentation": "/usr/share/doc/containernetworking-plugins/meta_firewall.md", "backend": "iptables" } ] } pi@raspberrypi:~ $ So looks like I do have the old CNI networking. pi@raspberrypi:~ $ sudo find / -iname '*cni*' /usr/lib/systemd/system/cni-dhcp.socket /usr/lib/systemd/system/cni-dhcp.service /usr/lib/cni /usr/share/doc/buildah/examples/cni-examples /usr/share/doc/podman/examples/cni /var/lib/systemd/deb-systemd-helper-enabled/cni-dhcp.service.dsh-also /var/lib/systemd/deb-systemd-helper-enabled/cni-dhcp.socket.dsh-also /etc/cni pi@raspberrypi:~ $ Is there any chance of this working in 32-bit ARMv6?
