#### 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__](https://stedolan.github.io/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.
