313 Extracting the list of container registries with a Go template
317 If shell completion is enabled, type podman info --format={{. and then
318 press [TAB] twice.
319 $ podman info --format={{.
322 {{.Host. {{.Plugins. {{.Registries}} {{.Store. {{.Version.
323 Press R [TAB] [ENTER] to print the registries information.
327 $ podman info -f {{.Registries}}
330 map[search:[registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]]
331 $
332 The output still contains a map and an array. The map value can be ex‐
336 tracted with
337 $ podman info -f '{{index .Registries "search"}}'
340 [registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]
341 The array can be printed as one entry per line
345 $ podman info -f '{{range index .Registries "search"}}{{.}}\n{{end}}'
348 registry.fedoraproject.org
349 registry.access.redhat.com
350 docker.io
351 quay.io
352 Extracting the list of container registries from JSON with jq
357 The command-line JSON processor jq can be used to extract the list of
358 container registries.
359 $ podman info -f json | jq '.registries["search"]'
362 [
363 "registry.fedoraproject.org",
364 "registry.access.redhat.com",
365 "docker.io",
366 "quay.io"
367 ]
368 The array can be printed as one entry per line
372 $ podman info -f json | jq -r '.registries["search"] | .[]'
375 registry.fedoraproject.org
376 registry.access.redhat.com
377 docker.io
378 quay.io
379 Note, the Go template struct fields start with upper case. When running
383 podman info or podman info --format=json, the same names start with
384 lower case.
