This repository provide a tool which allows generating docker images using templates.

pkr comes from pocker, which was the first name of this software.

To learn how to use pkr, you can have a look at our examples here.

See https://docs.docker.com/install/

pkr requires gcc and the python-devel libraries.

## Install the environment

1. Install its system dependencies

   yum install epel-release
   yum update
   yum install gcc python-pip python-devel
   

Note: you might also want to install git to automatically fetch sources from the Git repository.

3. Update pip and setuptools to their latest version

   pip install --upgrade setuptools
   pip install --upgrade pip
   

## Install with pip

Install it on your machine, or in a virtual env

```
pip install pkr
```

## Install from the sources

1. Clone the repository

   git clone XXX
   

2. Install it on your machine, or in a virtual env

   cd pkr
   pip install -e .
   

1. Use either directly the pkr command by running the image, or via the interactive mode. The image has a volume for storing its Kard (See pkr documentation), and also needs to access the docker socket.

   # Direct mode
   docker run \
       -v /run/docker.sock:/run/docker.sock \ 
       -v /home/sami/pkr/kard:/pkr/kard \
       pkr:dev pkr <command>
   
   # Interactive mode
   docker run -ti \
       -v /run/docker.sock:/run/docker.sock \
       -v /home/sami/pkr/kard:/pkr/kard \
       pkr:dev bash
   

In the source folder, run the following command:

docker build -t pkr:<TAG_NAME> .
