 === Startup the container and install xpra ===
 {{{
-    hostname# docker run -it centos:latest /bin/bash
-    a370b5e014ca# cd /etc/yum.repo.d
-    a370b5e014ca# curl -O https://winswitch.org/downloads/CentOS/winswitch.repo
-    a370b5e014ca# yum repolist
-    a370b5e014ca# yum install xpra
+    hostname# docker run -it -h container -p 192.168.99.100:10010:10010 centos:latest /bin/bash
+    root@container# cd /etc/yum.repo.d
+    root@container# curl -O https://winswitch.org/downloads/CentOS/winswitch.repo
+    root@container# yum repolist
+    root@container# yum install xpra
 }}}
+
+=== Install dependency packages ===
+* You may hit bellow error if you run xpra in container now:
+{{{
+  /bin/xpra_Xdummy: line 52: which: command not found
+   failed to locate Xorg binary to run
+   2015-12-23 16:19:11,020
+   2015-12-23 16:19:11,024 Xvfb command has terminated! xpra cannot continue
+}}}
+ this is because xvfb and which is not installed on centos7.2 official image. We need to install it
+{{{
+    root@container#yum install  xorg-x11-server-Xvfb
+    root@container#yum install which
+}}}
+
+=== Generate uuid for container ===
+* You may hit UUID problem:
+{{{
+   D-Bus library appears to be incorrectly set up; failed to read machine uuid: UUID file 
+   '/etc/machine-id'       should contain a hex string of length 32, not length 0, with no other text
+}}}
+which can be resolved by:
+{{{
+    root@container#dbus-uuidgen >/etc/machine-id
+}}}
+=== Run xpra in container ===
+* Create a new user in container:
+{{{
+    root@container# useradd -m xpra1
+   root@container# passwd xpra1
+}}}
+* Start xpra server with the created user (you may need to yum install emacs if you also want to run emacs):
+{{{
+  root@container# su - xpra1
+  xpra1@container$ xpra start :100 --start-child=emacs --bind-tcp=0.0.0.0:10010
+}}}
+
+* After that you can connect with xpra client!!
