podman-container-inspect - Man Page

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 will render all results in a JSON array. If a format is specified, the given template will be 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:

PlaceholderDescription

.ResolvConfPathPath to container's resolv.conf file (string)
.RestartCountNumber of times container has been restarted (int)
.RootfsContainer rootfs (string)
.SizeRootFsSize of rootfs, in bytes [1]
.SizeRwSize of upper (R/W) container layer, in bytes [1]
.State ...Container state info (struct)
.StaticDirPath to container metadata dir (string)

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

--latest, -l

Instead of providing the container name or ID, use the last created container. If you use methods other than Podman to run containers such as CRI-O, the last started container could be from either of those methods.

(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

$ podman container inspect foobar
