352 Extracting the list of container registries with a Go template
356 If shell completion is enabled, type podman info --format={{. and then
357 press [TAB] twice.
358 $ podman info --format={{.
360 {{.Host. {{.Plugins. {{.Registries}} {{.Store. {{.Version.
361 Press R [TAB] [ENTER] to print the registries information.
365 $ podman info -f {{.Registries}}
367 map[search:[registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]]
368 $
369 The output still contains a map and an array. The map value can be ex‐
373 tracted with
374 $ podman info -f '{{index .Registries "search"}}'
376 [registry.fedoraproject.org registry.access.redhat.com docker.io quay.io]
377 The array can be printed as one entry per line
381 $ podman info -f '{{range index .Registries "search"}}{{.}}\n{{end}}'
383 registry.fedoraproject.org
384 registry.access.redhat.com
385 docker.io
386 quay.io
387 Extracting the list of container registries from JSON with jq
392 The command-line JSON processor jq can be used to extract the list of
393 container registries.
394 $ podman info -f json | jq '.registries["search"]'
396 [
397 "registry.fedoraproject.org",
398 "registry.access.redhat.com",
399 "docker.io",
400 "quay.io"
401 ]
402 The array can be printed as one entry per line
406 $ podman info -f json | jq -r '.registries["search"] | .[]'
408 registry.fedoraproject.org
409 registry.access.redhat.com
410 docker.io
411 quay.io
412 Note, the Go template struct fields start with upper case. When running
416 podman info or podman info --format=json, the same names start with
417 lower case.
