podman-info(1)

💅 podman-info(1) — like, the whole vibe of podman-info

okay so bestie, welcome to podman-info(1), from the General Commands Manual section. this is the page where podman spills all its tea about the system it's living on. 🫖✨

✨ NAME ✨

podman-info — Display Podman related system information

like, it shows you stuff. about podman. system stuff. iykyk.

🦋 SYNOPSIS 🦋

podman info [options]

podman system info [options]

two ways in, same destination. podman system info is the lorg version, podman info is the lowkey shortcut. both slay.

🌸 DESCRIPTION 🌸

so what does it actually do? it Displays information pertinent to the host, current storage stats, configured container registries, and build of podman. basically the full carfax on your setup. 💅

and the host info? it includes configured CDI spec directories and resolved CDI devices when present. so if you've got CDI stuff configured, it shows up. if not, it's giving nothing and that's fine too.

🎀 OPTIONS 🎀

⭐ --format, -f=format

Change output format to "json" or a Go template.

no cap, this is the main character option. you want json? say json. you want a Go template? go off, build your own lil formatted masterpiece. 🌈

here's the placeholder tea — when you're templating, these are the top-level spots you can reach into:

• .Host ... — Info pertaining to ...the host on which podman is running 💻
• .Plugins ... — Info pertaining to ...external plugins 🔌
• .Registries ... — Info pertaining to ...configured registries 📋
• .Store ... — Info pertaining to ...the storage driver and paths 💾
• .Version ... — Info pertaining to ...podman version 🏷️

ngl, this is where the original had a cute lil table. we've gone with a list 'cause tables are so not invited to this party. same facts tho, fr fr.

Each of the above branch out into further subfields, more than can reasonably be enumerated in this document. so like, there's a whole tree under each one — .Host alone has a million little branches — and the manpage authors were like "bestie we're not typing all that out." respect honestly. 🙈

so if you're writing a template and you're like "what fields exist under .Store?" — the answer is "a lot, go look." 🧚

✨ EXAMPLES ✨

🧚 Extracting the list of container registries with a Go template 💅

if shell completion is enabled, type podman info --format={{. and then press Tab twice. it'll bless you with:

$ podman info --format={{.
{{.Host.         {{.Plugins.      {{.Registries}}  {{.Store.        {{.Version.

press R, Tab, Enter to print the registries information:

$ podman info -f {{.Registries}}
map[search:[registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]]
$

the output still contains a map and an array. the map value can be extracted with:

$ podman info -f '{{index .Registries "search"}}'
[registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]

and the array can be printed as one entry per line:

$ podman info -f '{{range index .Registries "search"}}{{.}}\n{{end}}'
registry.fedoraproject.org
registry.access.redhat.com
docker.io
quay.io

---

🍓 Extracting the list of container registries from JSON with jq 🦋

the command-line JSON processor jq can be used to extract the list of container registries:

$ podman info -f json | jq '.registries["search"]'
[
  "registry.fedoraproject.org",
  "registry.access.redhat.com",
  "docker.io",
  "quay.io"
]

the array can be printed as one entry per line:

$ podman info -f json | jq -r '.registries["search"] | .[]'
registry.fedoraproject.org
registry.access.redhat.com
docker.io
quay.io

⚠️ tiny but important note: the Go template struct fields start with upper case. when running podman info or podman info --format=json, the same names start with lower case. iykyk 💅
