~/Google\ Drive/:cd ~/Google\ Drive/ mkdir projects cd projects mkdir my_project.git cd my_project.git git init --bareIn the test project workspace, a project is added to the repository as follows:
cd my_project git init git add * git commit -m "My initial commit message" git remote add origin ~/Google\ Drive/projects/my_project.git git push -u origin masterNow I can clone the project:
git clone ~/Google\ Drive/projects/my_project.git cd my_project
boot2docker up
var express = require('express');
var DEFAULT_PORT = 8080;
var PORT = process.env.PORT || DEFAULT_PORT;
var app = express();
app.get('/', function (req, res) {
res.send('Hello World\n');
});
app.listen(PORT)
console.log('Running on http://localhost:' + PORT);
Create the Docker package.json file:
{
"name": "docker-centos-hello-world",
"private": true,
"version": "0.0.1",
"description": "Node.js Hello World app on CentOS using docker",
"author": "Daniel Gasienica",
"dependencies": {
"express": "3.2.4"
}
}
Create the Dockerfile:
FROM centos:6.4 RUN rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm RUN yum install -y npm ADD . /src RUN cd /src; npm install EXPOSE 8080 CMD ["node", "/src/index.js"]The layout of your directory should be as follows:
> ls Dockerfile index.js package.jsonBuilding the image:
docker build -t peter/centos-node-hello .Verify if the image exists:
docker imagesThis should print:
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE peter/centos-node-hello latest 6c55823e6868 4 hours ago 672.2 MB
docker run -p 49160:8080 -d peter/centos-node-helloThe option
-p exposes the port 8080 to 49160. This is essential. Without that, the server is not visible to a client.docker psYou should see:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 578bd01b0407 peter/centos-node-hello:latest node /src/index.js 4 hours ago Up 2 hours 0.0.0.0:49160->8080/tcp jovial_feynmanInspect the image:
docker inspect 578bd01b0407You should see a JSON output showing all relevant information:
...
"PortBindings": {
"8080/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "49160"
}
]
}
...
If the -p was not given when starting the process, HostPort would have been null and the application would not have been visible to clients.
Test it:
curl localhost:49160Now you should see:
Hello World.Stop and start the process again:
docker stop 578bd01b0407
docker ps doesn't show the process any more. docker ps -a lists the process as Exited:
> docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 578bd01b0407 peter/centos-node-hello:latest node /src/index.js 12 minutes ago Exited (143) 9 seconds ago jovial_feynmanSo, start it again:
docker start 578bd01b0407Test if the process is running:
> docker -ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 578bd01b0407 peter/centos-node-hello:latest node /src/index.js 14 minutes ago Up 2 seconds 0.0.0.0:49160->8080/tcp jovial_feynmanCheck the logs:

According to the documentation, the boot2docker VM must be powered off for this to work:
> boot2docker stopRun following script (this takes a while):
for i in {49000..49900}; do
VBoxManage modifyvm "boot2docker-vm" --natpf1 "tcp-port$i,tcp,,$i,,$i";
VBoxManage modifyvm "boot2docker-vm" --natpf1 "udp-port$i,udp,,$i,,$i";
done
Starting docker VM again and login using ssh:> boot2docker up > boot2docker sshThen you should see:
wildfly-camel-installer-1.0.0.Alpha1.jar 
To add a new user execute the add-user.sh script within the bin folder of your WildFly installation and enter the requested information.Try that and answer the questions:
