Full Description


This is a Docker image project with Rails and MySQL.


Installed these


## Clone this Project.
git clone

## CD
cd hello-docker-rails

## Init boot2docker
boot2docker init

## Run boot2docker
boot2docker up

## Run MySQL Server
docker run -p 3306:3306 -d --name db -e MYSQL_ROOT_PASSWORD=hoge mysql 

## Build App Server Image
docker build -t local/project .

## Run App Server
docker run -i -p 80:3000 --link db:db --name app -t local/project

## Get Virtual Machine's IP & Access!!
boot2docker ip


See the Demo. But if you already know the DockerHub, the usage is Super Easy. Take a look below.

## Run MySQL Server
docker run -p 3306:3306 -d --name db -e MYSQL_ROOT_PASSWORD=hoge mysql 

## Run App Server
docker run -i -p 80:3000 --link db:db --name app -t xtity/hello-docker-rails

Just 2 steps to make a VM with Rails and MySQL :)


boot2docker setting

The boot2docker requires these environmental variables.


We could export these vars in every time we use boot2docker.
But This way isn't handy.
For example, you could execute the below command to set these in .bash_profile.

echo -e '\n# boot2docker config\nif [ "`boot2docker status`" = "running" ]; then\n    $(boot2docker shellinit 2>/dev/null)\nfi\n' >> ~/.bash_profile

Try it :)

Persistent Database

To persist database, you need mount a data volume to database container.
If not, the data will be gone when you remove database container.
Separate DBMS and DB data!

There is a example below.

# Get up data volume container
docker run -t -v /var/lib/mysql --name db_data busybox

# Run MySQL Server mounted the volume
docker run -t -d -p 3306:3306 --volumes-from db_data --name db -e MYSQL_ROOT_PASSWORD=hoge mysql

Check the MySQL data is persisted when you rerun new database container after the database container removed :)

Persistent Application Data

Like the 'Persistent Database', you may want application data to persist.
Yeah, me too. So, how about below.

# Get up app data volume container
docker run -t -v /var/www/html --name app_data busybox

# Run App Server mounted the volume
docker run -d --volumes-from app_data -p 80:3000 --link db:db --name app -t xtity/hello-docker-rails

That's it!
It's very easy way so that it's similar to the 'Persistent Database' :)

Sharing Application Data

The next step of the 'Persistent Application Data' is sharing the data to your host OS like Windows, Mac OS X and so on.
A usual solution is using Samba Server, I think.

# Run Samba Container 
docker run --rm -v /usr/local/bin/docker:/docker -v /var/run/docker.sock:/docker.sock svendowideit/samba app_data

When you execute this command, you would see some messages to mount the volume.
They are pretty easy to understand how to use and I think you are not going to lost your way.
But if your host OS is Mac OS X and you use Eclipse IDE, take a look below.

# In case that your boot2docker's ip is and your mount point is ~/eclipse/workspace/app_data
mount_smbfs //GUEST@ ~/eclipse/workspace/app_data

You can mount the volume where ever you want :)
