PRODUCTION: AWS

build your ami

PRODUCTION: DIGITALOCEAN

build a droplet snapshot

packer build --only digitalocean packer.json

install doctl tool and login

brew install doctl
doctl auth login

run the newly created image

# find the image id
image=$(doctl compute image list --format ID,Name | grep packer | tail -n 1 | cut -f1)
ssh_key_fingerprint=$(doctl compute ssh-key list | grep primary | cut -f3)

# launch a droplet from the packer created snapshot
doctl compute droplet create test-$image --size 512mb --image $image --region nyc2 --ssk-keys $ssh_key_fingerprint

check it's actually running and view the app

ip=$(doctl compute droplet list | grep test-$image | cut -f4)
curl http://$ip
echo "Open up your web browser to http://$ip to interact with the app!"

DEVELOPMENT: DOCKER (DOCKERDOCKER)

install Docker Toolbox

https://docs.docker.com/engine/installation/mac/

brew cask install dockertoolbox

create a host machine, since we're on OSX and cannot run docker natively

docker-machine create --driver virtualbox default

The command also creates a machine configuration in the ~/.docker/machine/machines/default directory. You only need to run the create command once. Then, you can use docker-machine to start, stop, query, and otherwise manage the VM from the command line.

connect your shell to the newly created machine

eval "$(docker-machine env default)"

run hello-world to verify the setup

docker run hello-world

Hello from Docker. This message shows that your installation appears to be working correctly.
