# CentOS Linux for Docker
Docker image with CentOS GNU/Linux.
## Synopsis
This is a set of scripts designed to create Docker images with CentOS
GNU/Linux.
The Docker images resulting from these scripts should be the ones used to
instantiate a CentOS container.
## Getting Started
There are a couple of things needed for the script to work.
### Prerequisites
Docker, either the Community Edition (CE) or Enterprise Edition (EE), needs to
be installed on your local computer.
#### Docker
Docker installation instructions can be found
[here](https://docs.docker.com/install/).
### Usage
In order to create a Docker image using this Dockerfiles you need to run the
`docker` command with a few options.
```shell
docker image build --force-rm --no-cache --progress plain --file /Dockerfile --tag /:
```
- `` - *[required]* The user that will own the container image (e.g.: "johndoe").
- `` - *[required]* The container name (e.g.: "centos").
- `` - *[required]* The container tag (e.g.: "latest").
- `` - *[required]* The location of the Dockerfile folder.
- `` - *[required]* The variant that is being build (`centos7`, `centos8`, `centos8-stream` or `centos9-stream`).
A build example:
```shell
docker image build --force-rm --no-cache --progress plain --file centos9-stream/Dockerfile --tag johndoe/my_centos:centos9-stream .
```
To clean any _`none`_ image(s) left by the build process the following
command can be used:
```shell
docker image rm `docker image ls --filter "dangling=true" --quiet`
```
You can also use the following command to achieve the same result:
```shell
docker image prune -f
```
### Add Tags to the Docker Image
Additional tags can be added to the image using the following command:
```shell
docker image tag /:
```
### Push the image to Docker Hub
After adding an image to Docker, that image can be pushed to a Docker registry... Like Docker Hub.
Make sure that you are logged in to the service.
```shell
docker login
```
When logged in, an image can be pushed using the following command:
```shell
docker image push /:
```
Extra tags can also be pushed.
```shell
docker image push /:
```
