## 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` flag. Various image instructions can be
|
|
configured with the `--change` flag and a commit message can be set using the
|
|
`--message` flag. The container and its processes are paused while the image is
|
|
committed. This minimizes the likelihood of data corruption when creating the new
|
|
image. If this is not desired, the `--pause` flag can be set to false. When the commit
|
|
is complete, Podman will print out the ID of the new image.
|
|
|
|
If *image* does not begin with a registry name component, `localhost` will be added to the name.
|
|
If *image* is not provided, the values for the `REPOSITORY` and `TAG` values of the created image will each be set to `<none>`.
|
