drafa/node repository overview
IMAGEN DE NODE
This image creates a container to run an application node, which should be on your machine and shared with a volume.
This image is on beta test. Not recomend for production use. Wait a few weeks, I'm working on it.
Structure of project
node_server
|_ app/
| |_ app.js
|_ node_modules/
| |_ <dependencies>
|_ package.json
|_ .editorconfig
I recomend use of editorconfig file. See most in editorconfig website
Preparing the environment
# Generates all directories
mkdir -p $HOME/Docker/node_server/app
cd $HOME/Docker/node_server
touch app/app.js package.json
Now, you need create two files (app.js and package.json). (For example:)
app.js
var express = require("express"),
app = express(),
http = require("http"),
server = http.createServer(app);
app.configure(function () {
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
});
app.get('/', function(req, res) {
res.send("<h2>Hello world!<h2>Node server running on http://localhost:**PORT**<br/>This is a dummy app. You can deploy your app usign volumes<br/><br/>Example:<br/>****************************************************************<br/>docker run -d -p <host>:<port>:8888 -v $HOME/node/app:/node/app<br/>****************************************************************<br/>Where $HOME/node/app is a directory for your computer and<br/>/node/app is the docker container.");
});
server.listen(**PORT**, function() {
console.log("Node server running on http://localhost:**PORT**");
});
Rememeber rename your app port to
8888or to**PORT**. If not change it, app not work. If you desire use other port, donwload Dockerfile and rebuild it.
package.json
{
"name" : "node-api-rest-example",
"version" : "0.0.1",
"dependencies" : {
"express" : "3.2.6",
"mongoose" : "3.6.11",
"gulp" : "3.9.0",
"bower" : "1.5.3"
}
}
Install the container
You are prepared for create the container. Execute a docker run with volume for /node/app (If not create a volume, then not working)
docker run --name node -d -p 127.0.0.1:8888:8888 -v $HOME/Docker/node_server:/node/server drafa/node
You can redefine the host
127.0.0.1::for other.You can redefine the host port
:8888:for other.You can't redefine the container port
::8888.You need create a volume for this container and create a
app.jsandpackage.json.
And now... you have a node server on your machine.
Remember
- This container creates a file node_modules on your host volume, this folder have drwxr-xr-x privileges (owner: root). If your user can't execute with root privileges, execute:
chmod 777 $HOME/docker/node/app/node_modules, but it not recommended for Production. - If you download this proyect from the github then can't edit
run.shscript, you need usechmodbecause its defined with r-x------ privileges. Execute:chmod 700 run.shfor edit the file
