Dockerized Node.js App on Elastic Beanstalk Example

Example of developing and deploying a dockerized Node.js app to Elastic Beanstalk

source on Github at pfeilbr/Elastic-Beanstalk-Docker-Node.js-Example

Local Development Workflow

1. Edit code. e.g. index.js

2. Build image

   $ docker build --tag="pfeilbr/eb-docker-node-example" .
   

   ``

3. Run

   $ docker run -p 80:80 -it -rm -name eb-docker-node-example pfeilbr/eb-docker-node-example
   

   ``

4. Get docker host ip (optional. only if using boot2docker)

   $ boot2docker ip
   

   ``

5. Open browser to http://<boot2docker ip>

Initial Deployment

1. Init git repo

   $ git init .
   

   ``

2. Add files to repo

   $ git add .
   

   ``

3. Commit changes

   $ git commit -m "init"
   

   ``

4. Create eb app

   $ eb init # populate details
   

   ``

   Populate all details

5. Create environment for app

   $ eb create dev-env
   

   ``

   IMPORTANT Must immediately update the ec2 instance with tags so it doesn’t get terminated. Enable termination protection on the ec2 instance.

Output

Deploying Updates

1. Modify code and test via [Local Development Workflow]

2. Commit changes

   $ git commit -a -m "my updates"
   

   ``

3. Deploy to eb

   $ eb deploy
   

   ``

NOTE: Takes between 3-5 min to deploy changes

Output

Establish Interactive Bash Shell in Running Docker Container

1. ssh into ec2 docker host server

   $ eb ssh
   

   ``

2. Get container name

   $ sudo docker ps # save off name of container
   

   ``

3. Connect/attach with an interactive bash session

   $ sudo docker exec -i -t <container name> bash
   

   ``
