## Examples
|
|
|
|
### Creating a new image from an existing container
|
|
An existing Fedora based container has had Apache installed while running
|
|
in interactive mode with the bash shell. Apache is also running. To
|
|
create a new image run `docker ps` to find the container's ID and then run:
|
|
|
|
```bash
|
|
$ docker commit -m="Added Apache to Fedora base image" \
|
|
-a="A D Ministrator" 98bd7fc99854 fedora/fedora_httpd:20
|
|
```
|
|
|
|
Note that only `a-z0-9-_.` are allowed when naming images from an
|
|
existing container.
|
|
|
|
### Apply specified Dockerfile instructions while committing the image
|
|
If an existing container was created without the DEBUG environment
|
|
variable set to "true", you can create a new image based on that
|
|
container by first getting the container's ID with `docker ps` and
|
|
then running:
|
|
|
|
```bash
|
|
$ docker container commit -c="ENV DEBUG true" 98bd7fc99854 debug-image
|
|
```
