+##Creating a build server for AlpineLinux
+
+On Alpine server run : at-begining.sh to install necessary tools.
+
+##Change to the build user :
+
+```su - build```
+
+##Create signing key:
+
+```abuild-keygen -i -a (-i installs them in /etc/apk/keys)```
+
+##Quick check : 
+
+```ls -lah /etc/apk/keys/build-xxxxxxxx.rsa.pub```
+
+##Clone the git repository : 
+
+```git clone --depth=1 https://gitlab.alpinelinux.org/alpine/aports.git```
+
+##Update : 
+
+```sudo apk updat```
+
+Copy script 'create-iso.sh' in '/home/build'
+
+You must enter a profile name to launch the creation of the iso. The iso is built with Edge sources to have Kubernetes tools. 
+For example ./create-iso.sh myKube.
+The iso is generated in the ~/iso folder.
