DockerBeanstalkSample

Hello World in Golang served with Docker. Deployable to AWS Beanstalk. For OSX.

Dependencies

• Docker Machine: Download latest release from https://github.com/docker/machine/releases
• boot2docker: brew install boot2docker ( Only required if docker machine does not work )
• Docker: brew install docker
• VirtualBox: Download 4.3.26 for OSX from here
• Golang: brew install go. Ensure that $GOPATH has been set. Usually to something like: ~/go/
• AWS Elastic Beanstalk CLI: pip install awsebcli

Setting up Docker Machine

• Download the latest release from https://github.com/docker/machine/releases

• Rename executable to docker-machine, copy it to /usr/local/bin/docker-machine and chmod +x /usr/local/bin/docker-machine

• Create a VM using: docker-machine create -d virtualbox dev

    Creating VirtualBox VM...
    Creating SSH key...
    Starting VirtualBox VM...
    Starting VM...
    To see how to connect Docker to this machine, run: docker-machine env dev
  

• Execute: docker-machine env dev

    export DOCKER_TLS_VERIFY="1"
    export DOCKER_HOST="tcp://192.168.99.100:2376"
    export DOCKER_CERT_PATH="/Users/hemantasapkota/.docker/machine/machines/dev"
    export DOCKER_MACHINE_NAME="dev"
    # Run this command to configure your shell:
    # eval "$(docker-machine env dev)"
    # Save the exports to ~/.bashrc or ~/.zshrc file
  

• Check the status of the VM: docker-machine ls

    NAME   ACTIVE   DRIVER       STATE     URL                         SWARM
    dev    *        virtualbox   Running   tcp://192.168.99.100:2376
  
    # Take a note of the IP address of the machine
  

Setting up Boot2Docker ( Only set this up if, docker-machine fails for some reason )

• boot2docker init

Latest release for github.com/boot2docker/boot2docker is v1.6.2
Downloading boot2docker ISO image...
Success: downloaded https://github.com/boot2docker/boot2docker/releases/download/v1.6.2/boot2docker.iso
        to /Users/hemantasapkota/.boot2docker/boot2docker.iso

• boot2docker up

# Run the following exports. Note the IP address for DOCKER_HOST in your machine may be different.
export DOCKER_HOST=tcp://192.168.59.103:2376▫
export DOCKER_CERT_PATH=/Users/hemantasapkota/.boot2docker/certs/boot2docker-vm▫
export DOCKER_TLS_VERIFY=1

Add those variables to your ~/.bashrc or ~/.zshrc ( if you're using Z Shell or oh-my-zsh )

Docker

• Clone this repo: git clone https://github.com/OrganicCoffeeNepal/DockerBeanstalkSample

• Build docker image: docker build -t docker-beanstalk-sample-app .

  • You should get a Successfuly built 9ac180ca5317 message in th end.

• Run the app: docker run -it --rm -p 8080:8080 docker-beanstalk-sample-app

  • Log: [negroni] listening on :8080

• Test the app

  • List the IP using docker-machine ls
  • If you're using boot2docker, get boot2docker's ip: boot2docker ip. Example output: 192.168.59.100
  • open http://192.168.59.100:8080. You should have a running app now.

Deploy to AWS Beanstalk

You'll need Amazon AWS account. If you don't have one, you can register for Amazon's free tier service.

Elastic Beanstalk Init - eb init

cd DockerBeanstalkSample

eb init -i

#Select your region

# AWS Credentials - http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSGettingStartedGuide/AWSCredentials.html
# Provide your aws-access-id
# Provide your aws-secret-key
# Note if you're creating new user through AWS IAM, you'll need to attach AmazonEC2FullAccess and AWSBeanstalkFullAccess policies to the user.

# Application Name: DockerBeanstalkSample

# It appears you are using Docker. Is this correct ?
# Answer: Y

# Do you want to set up SSH for your instances ?
# Answer: Y

# Select a keypair:
# Answer: 2

# Type a keypair name:
# (Default is aws-eb): aws-eb
# Generating public/private rsa key pair.
# Enter passphrase ( emptry for no passphrase): sample

Elastic Beanstalk Create - eb create

eb create

# Enter environment name (default is DockerBeanstalkSample-0): 
# Enter DNS CNAME prefix (default is DockerBeanstalkSample-0):

About 5 - 10 minutes later, you should get: INFO: Successfully launched environment: DockerBeanstalkSample-0
