## NAME
|
|
podman\-commit - Create new image based on the changed container
|
|
|
|
## SYNOPSIS
|
|
**podman commit** [*options*] *container* [*image*]
|
|
|
|
**podman container commit** [*options*] *container* [*image*]
|
|
|
|
## DESCRIPTION
|
|
**podman commit** creates an image based on a changed *container*. The author of the image can be set using the **--author** OPTION. Various image instructions can be configured with the **--change** OPTION and a commit message can be set using the **--message** OPTION. The *container* and its processes aren't paused while the image is committed. If this is not desired, the **--pause** OPTION can be set to *true*. When the commit is complete, Podman prints out the ID of the new image.
|
|
|
|
If `image` does not begin with a registry name component, `localhost` is added to the name.
|
|
If `image` is not provided, the values for the `REPOSITORY` and `TAG` values of the created image is set to `<none>`.
|
|
|
|
