podman info [options]

podman system info [options]

Displays information pertinent to the host, current storage stats, configured container registries, and build of podman.

--format, -f=format

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:

If shell completion is enabled, type podman info --format={{. and then press [TAB] twice.

$ 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]

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

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

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.
