Build and tag docker repo for deployment

deploy.sh

#!/bin/bash

# Builds and pushed docker image of a git repo, tagging the git repo and docker image with the
# same tag. Make sure you are logged into docker and that boot2docker is running if you're on
# OSX or Windows

# Check that a version tag was given
if [ $# -eq 0 ]
  then
    echo "No version tag supplied, please enter a version tag as the first parameter of this script"
    exit 1
fi

# Save the git repo as it is and tag it with the version number
echo "***** COMMITING TO GIT REPO"
git add .
git commit -m "Production Version $1"
echo "***** TAGGING LATEST COMMIT AS $1"
git tag $1

# Build and push to docker hub
echo "***** BUILDING DOCKER IMAGE (with tag $1)"
docker build -t <docker_username>/<docker_repo_name>:$1 .
echo "***** PUSHING DOCKER IMAGE"
docker push <docker_username>/<docker_repo_name>

Run this script with a version tag e.g ./deploy.sh v0.1.3

Make sure you change <docker_username> to your docker username and <docker_repo_name> to the name of your repo on docker.

This is particularly useful for deploying docker images to Elastic Beanstalk on AWS. After running this script with your version tag, add the version tag to your Dockerrun.aws.json file like so

"AWSEBDockerrunVersion": "1",
 "Image": {
     "Name" : "<docker_username>/<docker_repo_name>:<version_tag>",
     "Update" : "true"
 }

Upload this to the Elastic Beanstalk console and and type in the same version tag, then all your Elastic Beanstalk versions will be tied to the docker images and git commits with the same version tag.
