Installing MongoDB or other packages with Node JS using "ebextensions"
Recently wanted to
install a NodeJS application on Elastic Beanstalk. That was easy :).
One can use AWS EB
Console to upload a zipped nodejs application and be done with it.
However wanted to
install and run MongoDB in the beanstalk image that gets created when the
application get deployed.
So the easiest way
to get this done is to use CLI for AWS EB.
Using Elastic Beanstalk CLI ( Command Line Interface ) simplifies so many things
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/eb-cli3-install.html
describes the steps to install the same.
In short you would
need, Python 2.7 with PIP and once you have pip EB CLI can be installed with
"pip install awsebcli"
One would have to
either create a new EB environment or configure an existing nodeJs application
source code folder to an EB environment.
On my AWS
environment, I have few glitches that can be avoided ( network configurations
are slightly restrictive) only when the EB applications is created from AWS Web
Console, hence I would not be using "eb create", but I create an
empty EB NodeJs application environment and on my local machine map the
application using "eb init"
Moving
on, assuming you have everything on the folder on your local computer and ready to test EB CLI and container
customization, create a folder ".ebextensions". To customize the EB
container , you can include one or more configuration files with your source
bundle. Configuration files must be named with the extension .config (for example, myapp.config) and placed in an .ebextensions top-level directory in your
source bundle. Configuration files are executed in alphabetical order.
One can read about
it here
for linux and here
for windwos
For Installing Mongo
, Here is the config file
files:
"/etc/yum.repos.d/mongodb.repo":
mode: "000644"
