After installing Subversion in an Amazon EC2 instance, set the Security group to allow SSH from your IP and SVN from the EC2 instance's IP.
Connect to the Amazon EC2 instance using the key provided by Amazon and forward the Local SVN port to the Remote SVN port.
ssh -i ~/.ssh/AWS-ubuntu-key.pem ubuntu@xxx.xxx.xxx.xxx -L 3690:xxx.xxx.xxx.xxx:3690
You should now be able to connect to your remote SVN server via SSH tunnel using:
svn co svn://localhost/repository

One of the ideas behind Docker containers is that you create a sandbox environment segregated from the host environment in such a way that the configuration of the container can be guaranteed. However, when planning a Docker deployment, it can be useful to log into the container to troubleshoot unforeseen issues. As long as the lessons learned get conveyed into the Dockerfile and the image is rebuilt, then the original containerization intent can be achieved.
# show full id
sudo docker ps --notrunc
# use lxc-attach
sudo lxc-attach -n <full-id>

Putting the M in LAMP
In Part I we built a Dockerfile to generate the LAP part of a LAMP server. Now, all we need to do is add instructions to a Dockerfile in order to install and start MySQL.

Putting the LAP in LAMP
Assuming you have Docker installed and have a docker user within a docker group, you're ready to set up a Linux-Apache-MySQL-PHP (LAMP) Server.
As root, launch a container from the ubuntu image (not base):
$ sudo docker run -i -t ubuntu \bin\bash
In the launched container, install PHP and Apache2.
# apt-get install php5
# apt-get install apache2
Assuming everything goes well, exit the container and view the list of containers with "sudo docker ps -a".

The docker daemon always runs as root, and since docker version 0.5.2, docker binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root, and so, by default, you can access it with sudo.
