NAME

podman-search - Search a registry for an image

SYNOPSIS

podman search [options] term

DESCRIPTION

podman search searches a registry or a list of registries for a matching image. The user can specify which registry to search by prefixing the registry in the search term (e.g., registry.fedoraproject.org/fedora). By default, all unqualified-search registries in containers-registries.conf(5) are used.

The default number of results is 25. The number of results can be limited using the --limit flag. If more than one registry is being searched, the limit will be applied to each registry. The output can be filtered using the --filter flag. To get all available images in a registry without a specific search term, the user can just enter the registry name with a trailing "/" (example registry.fedoraproject.org/).

Note that podman search is not a reliable way to determine the presence or existence of an image. The search behavior of the v1 and v2 Docker distribution API is specific to the implementation of each registry. Some registries may not support searching at all. Further note that searching without a search term will only work for registries that implement the v2 API.

podman search [OPTIONS] TERM

OPTIONS

--authfile=path

Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json

Note: You can also override the default path of the authentication file by setting the REGISTRY_AUTH_FILE environment variable. export REGISTRY_AUTH_FILE=path

--filter, -f=filter

Filter output based on conditions provided (default [])

Supported filters are:

  • stars (int - number of stars the image has)
  • is-automated (boolean - true | false) - is the image automated or not
  • is-official (boolean - true | false) - is the image official or not

--format=format

Change the output format to a Go template

Valid placeholders for the Go template are listed below:

Placeholder Description
.Index Registry
.Name Image name
.Descriptions Image description
.Stars Star count of image
.Official "[OK]" if image is official
.Automated "[OK]" if image is automated
.Tag Repository tag

Note: use .Tag only if the --list-tags is set.

--limit=limit

Limit the number of results (default 25). Note: The results from each registry will be limited to this value. Example if limit is 10 and two registries are being searched, the total number of results will be 20, 10 from each (if there are at least 10 matches in each). The order of the search results is the order in which the API endpoint returns the results.

--list-tags

List the available tags in the repository for the specified image. Note: --list-tags requires the search term to be a fully specified image name. The result contains the Image name and its tag, one line for every tag associated with the image.

--no-trunc

Do not truncate the output (default false).

--tls-verify

Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true, then TLS verification will be used. If set to false, then TLS verification will not be used if needed. If not specified, default registries will be searched through (in /etc/containers/registries.conf), and TLS will be skipped if a default registry is listed in the insecure registries.

FILES

registries.conf (/etc/containers/registries.conf)

registries.conf is the configuration file which specifies which container registries should be consulted when completing image names which do not include a registry or domain portion.
