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.
