java-app-on-docker
Short example of working with Docker while developing Java application
Project structure:
src
- main - java
- resources
- webapp
- test - java
- resources
This application was created through the following steps:
-
npm install -g yo grunt-cli bower
-
npm install -g generator-ember
-
gem install compass
-
cd src/main/webapp
-
yo ember ` - [?] Would you like to include Bootstrap for Sass? (Y/n) Y
-
npm install grunt-connect-proxy --save-dev
-
npm install matchdep --save-dev
-
require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);
-
Add grunt.loadNpmTasks('grunt-connect-proxy'); to Gruntfile
-
proxies: [ { context: 'api', host: 'localhost', port: 8080, https: false, changeOrigin: true, xforward: false } ]
-
middleware: function (connect, options) { var proxy = require('grunt-connect-proxy/lib/utils').proxyRequest; return [ // Include the proxy first proxy, // Serve static files. connect.static(options.base), // Make empty directories browsable. connect.directory(options.base) ]; }
-
'configureProxies'
In order to run this application you have to perform:
-
cd src/main/webapp
-
npm install
-
bower install
In order to enable debugging for jetty servlet use: -Dorg.eclipse.jetty.servlet.LEVEL=ALL
In order to import data execute: mongoimport -v -d library -c books --jsonArray --file PATH_TO_PROJECT/src/test/resources/books_array.json
docker build -t="ihristov/library" .
docker run -p 8080:8080 -i -t ihristov/library
Don't forget to expose the port via the VirtualBox as well
To login docker container put /bin/bash as a final command in the entrypoint.sh script
Troubleshooting:
In case of : '... Error response from daemon: client and server don't have same version ...'
Run: boot2docker stop && boot2docker download && boot2docker up
