% podman-info 1 podman\-info - Display Podman related system information podman info [options] podman system info [options] Displays information pertinent to the host, current storage stats, configured container registries, and build of podman. Change output format to "json" or a Go template. | Placeholder | Info pertaining to ... | | - | | | .Host ... | ...the host on which podman is running | | .Plugins ... | ...external plugins | | .Registries ... | ...configured registries | | .Store ... | ...the storage driver and paths | | .Version ... | ...podman version | Each of the above branch out into further subfields, more than can reasonably be enumerated in this document. Run `podman info` for a YAML formatted response: ``` $ podman info host: arch: amd64 buildahVersion: 1.23.0 cgroupControllers: [] cgroupManager: systemd cgroupVersion: v2 conmon: package: conmon-2.0.29-2.fc34.x86_64 path: /usr/bin/conmon version: 'conmon version 2.0.29, commit: ' cpu_utilization: idle_percent: 96.84 system_percent: 0.71 user_percent: 2.45 cpus: 8 distribution: distribution: fedora variant: workstation version: "34" eventLogger: journald hostname: localhost.localdomain idMappings: gidmap: container_id: 0 host_id: 3267 size: 1 container_id: 1 host_id: 100000 size: 65536 uidmap: container_id: 0 host_id: 3267 size: 1 container_id: 1 host_id: 100000 size: 65536 kernel: 5.13.13-200.fc34.x86_64 linkmode: dynamic logDriver: journald memFree: 1833385984 memTotal: 16401895424 networkBackend: cni networkBackendInfo: backend: cni dns: package: podman-plugins-3.4.4-1.fc34.x86_64 path: /usr/libexec/cni/dnsname version: |- CNI dnsname plugin version: 1.3.1 commit: unknown package: |- containernetworking-plugins-1.0.1-1.fc34.x86_64 podman-plugins-3.4.4-1.fc34.x86_64 path: /usr/libexec/cni ociRuntime: name: crun package: crun-1.0-1.fc34.x86_64 path: /usr/bin/crun version: |- crun version 1.0 commit: 139dc6971e2f1d931af520188763e984d6cdfbf8 spec: 1.0.0 +SYSTEMD +SELINUX +APPARMOR +CAP +SECCOMP +EBPF +CRIU +YAJL os: linux pasta: executable: /usr/bin/passt package: passt-0^20221116.gace074c-1.fc34.x86_64 version: | passt 0^20221116.gace074c-1.fc34.x86_64 Copyright Red Hat GNU Affero GPL version 3 or later <https://www.gnu.org/licenses/agpl-3.0.html> This is free software: you are free to change and redistribute it.
