354 Extracting the list of container registries with a Go template
358 If shell completion is enabled, type podman info --format={{. and then
359 press [TAB] twice.
360 $ podman info --format={{.
363 {{.Host. {{.Plugins. {{.Registries}} {{.Store. {{.Version.
364 Press R [TAB] [ENTER] to print the registries information.
368 $ podman info -f {{.Registries}}
371 map[search:[registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]]
372 $
373 The output still contains a map and an array. The map value can be ex‐
377 tracted with
378 $ podman info -f '{{index .Registries "search"}}'
381 [registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]
382 The array can be printed as one entry per line
386 $ podman info -f '{{range index .Registries "search"}}{{.}}\n{{end}}'
389 registry.fedoraproject.org
390 registry.access.redhat.com
391 docker.io
392 quay.io
393 Extracting the list of container registries from JSON with jq
398 The command-line JSON processor jq can be used to extract the list of
399 container registries.
400 $ podman info -f json | jq '.registries["search"]'
403 [
404 "registry.fedoraproject.org",
405 "registry.access.redhat.com",
406 "docker.io",
407 "quay.io"
408 ]
409 The array can be printed as one entry per line
413 $ podman info -f json | jq -r '.registries["search"] | .[]'
416 registry.fedoraproject.org
417 registry.access.redhat.com
418 docker.io
419 quay.io
420 Note, the Go template struct fields start with upper case. When running
424 podman info or podman info --format=json, the same names start with
425 lower case.
