NAME
podman-info - Display Podman related system information

SYNOPSIS
podman info [options]

podman system info [options]

DESCRIPTION
Displays information pertinent to the host, current storage stats, configured container registries, and build of podman. Host information includes configured CDI spec directories and resolved CDI devices when present.

OPTIONS

  --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.

  Extracting the list of container registries with a Go template
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

  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

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.
