+# Sabayon base: a Docker Project #
+
+Attention! It's under strong development
+
+State: Alpha
+
+The purpose of this project is to provide an image of Sabayon base.
+It is just a gentoo stage3 + entropy
+
+UPDATE: Images are also on Docker Hub [sabayon/base-armhfp](https://registry.hub.docker.com/u/sabayon/base-armhfp/) and the already squashed image, 
+[sabayon/base-armhfp-squashed](https://registry.hub.docker.com/u/sabayon/base-armhfp-squashed/)
+
+## First steps on docker
+
+Ensure to have the daemon started and running:
+
+    sudo systemctl start docker
+
+## Building sabayon-base locally
+
+    git clone https://github.com/mudler/docker-sabayon-base-armhfp.git docker-sabayon-base
+    cd docker-sabayon-base
+    sudo docker build -t sabayon/base-armhfp .
+
+## Pulling sabayon-base from Docker Hub
+
+    sudo docker pull sabayon/base-armhfp
+
+## Converting the image from Docker to use it with [Molecules](https://github.com/Sabayon/molecules)
+
+### Only with undocker, without squashing the layers
+
+After pulling the docker image, install [undocker](https://github.com/larsks/undocker/) and then as root:
+
+    docker save sabayon/base-armhfp:latest | undocker -i -o base sabayon/base-armhfp:latest
+
+### Using [docker-squash](https://github.com/jwilder/docker-squash)
+You can also squash the image with [docker-squash](https://github.com/jwilder/docker-squash) and then extract your layers.
+
+    sudo docker save sabayon/base-armhfp:latest | sudo TMPDIR=/dev/shm docker-squash -t sabayon/base-armhfp:squashed > /your/prefered/path/base.tar
+
+You can replace /dev/shm with your prefered tmpdir
+
+### With undocker, but squashing the layers
+
+The squash can also been accomplished creating a container from the image, exporting it and then importing it back.
+
+    sudo docker run -t -i sabayon/base-armhfp:latest /bin/bash
+    $ exit # You should drop in a shell, exit, you should see a container id, otherwise find it :
+    sudo docker ps -l
+    sudo docker export <CONTAINER ID> | docker import - sabayon/base-armhfp:squashed
+    docker save sabayon/base-armhfp:squashed | undocker -i -o base sabayon/base-armhfp:squashed
+
+Docker will loose the history revision and then you can estract the layer, using as base for chroot.
+
+You now have the tree on the *base/* directory
+
+If you are planning to use the resulting files as a chroot, don't forget to set a nameserver on resolv.conf file
+
+    echo "nameserver 208.67.222.222" > base/etc/resolv.conf
+
+
+## 2 tricks on crosscompiling/building from an alien architecture
+
+### Enabling arm support
+
+Copy ext/qemu-arm-static to /usr/bin/binfmt, then:
+
+	echo ':arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff:/usr/bin/qemu-arm-binfmt:' > /proc/sys/fs/binfmt_misc/register
+	
+On the stage3, qemu-arm is not exported by default:
+
+	docker run -t -i -v /usr/bin/qemu-arm-binfmt:/usr/bin/qemu-arm-binfmt sabayon/gentoo-stage3-base-armhf uname -m
+
+On the base it is
+	
+	docker run -t -i sabayon/base-armhf uname -m
