NAME

podman-container-inspect - Display a container’s configuration

SYNOPSIS

podman container inspect [ options ] container [ container ...]

DESCRIPTION

This displays the low-level information on containers identified by name or ID. By default, this renders all results in a JSON array. If a format is specified, the given template is executed for each result.

OPTIONS

--format, -f=format

Format the output using the given Go template. The keys of the returned JSON can be used as the values for the --format flag (see examples below).

Valid placeholders for the Go template are listed below:

[1] This format specifier requires the --size option

--latest, -l

Instead of providing the container name or ID, use the last created container. Note: the last started container can be from other users of Podman on the host machine. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)

--size, -s

In addition to normal output, display the total file size if the type is a container.

EXAMPLE

Inspect the specified container and print its information in json format.

$ podman container inspect foobar
