CentOS Docker build scripts

===========================

This repository contains the kickstart files needed to build a CentOS Docker container from scratch

## Necessary tools

The Docker base containers for 6 and 7 are now created with tools included in CentOS itself. 

The following packages and dependencies are needed:

  yum install -y libguestfs-tools-c lorax virt-install libvirt

  systemctl start  libvirtd

## Build

In order to build the container, a rootfs tarball and Dockerfile are required.

We use lorax's livemedia-creator to create the rootfs tarball, but you'll need

a boot.iso start the process. Below you can find a set of example commands

that will produce a suitable rootfs tarball. Additionally you can also run the

containerbuild.sh script, which will fetch the iso, create the rootfs, and

generate a Dockerfile for you.

### The hard way

--

```bash

# curl http://mirror.centos.org/centos/7/os/x86_64/images/boot.iso -o /tmp/boot7.iso

# sudo livemedia-creator --make-tar --iso=/tmp/boot7.iso --ks=/path/to/centos-7.ks --image-name=centos-7-docker.tar.xz

```

--

Once livemedia-creator has finished, you can use the Dockerfile-TEMPLATE to

create a suitable Dockerfile.

### The easy way

After you've run this command, your rootfs tarball and Dockerfile will be

waiting for you in `/var/tmp/containers//`

--

```bash

# sudo ./containerbuild.sh centos-7.ks

```

--

Once this is done, you can delete the `boot.iso` files in /tmp if you wish.

## Usage

From here, you can either import the docker container via

```

cat centos-version-docker.tar.xz | docker import - container-name

```

Or you can create a Dockerfile to build the image directly in docker.

```

FROM scratch
