# [Buildah](https://www.youtube.com/embed/YVk5NgSiUw8) - a tool that facilitates building OCI container images

[![Go Report Card](https://goreportcard.com/badge/github.com/projectatomic/buildah)](https://goreportcard.com/report/github.com/projectatomic/buildah)
[![Travis](https://travis-ci.org/projectatomic/buildah.svg?branch=master)](https://travis-ci.org/projectatomic/buildah)

The Buildah package provides a command line tool that can be used to
* create a working container, either from scratch or using an image as a starting point
* create an image, either from a working container or via the instructions in a Dockerfile
* images can be built in either the OCI image format or the traditional upstream docker image format
* mount a working container's root filesystem for manipulation
* unmount a working container's root filesystem
* use the updated contents of a container's root filesystem as a filesystem layer to create a new image
* delete a working container or an image

## Example

From [`./examples/lighttpd.sh`](examples/lighttpd.sh):

```bash
$ cat > lighttpd.sh <<"EOF"
#!/bin/bash -x

ctr1=`buildah from ${1:-fedora}`

## Get all updates and install our minimal httpd server
buildah run $ctr1 -- dnf update -y
buildah run $ctr1 -- dnf install -y lighttpd

## Include some buildtime annotations
buildah config --annotation "com.example.build.host=$(uname -n)" $ctr1

## Run our server and expose the port
buildah config --cmd "/usr/sbin/lighttpd -D -f /etc/lighttpd/lighttpd.conf" $ctr1
buildah config --port 80 $ctr1

## Commit this container to an image name
buildah commit $ctr1 ${2:-$USER/lighttpd}
EOF

$ chmod +x lighttpd.sh
$ sudo ./lighttpd.sh
```
