Step 1: Launch a t2.medium instance (redhat 7.x)

Step 2: login and run the following commands

• pushd /tmp

• sudo yum install wget -y # to get files we need

• wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm # the epel repo for dockr-compose

• sudo yum install -y epel-release-latest-7.noarch.rpm

• popd

• sudo yum update -y

• sudo yum install vim-enhanced mlocate python-pip python-wheel python-wheel postgresql-devel wget tmux git -y

• sudo sh -c "wget -qO- https://get.docker.com/ | sh" # installs docker

• sudo groupadd -f docker && sudo usermod -aG docker $USER # creates docker user

Step 3: Logout and login back. (due to setting a new user group for docker)

Step4: install docker-compose

• sudo systemctl enable docker.service
• sudo systemctl start docker.service
• sudo pip install docker-compose # install docker compose now we have docker
• alias dc='docker-compose'
• echo "alias dc='docker-compose'" > ~/.bashrc
• echo "alias dc='docker-compose'" > ~/.bash_profile

step 5: Create DART environment files to run using docker-compose.

• cd ~
• mv dart/tools/vagrant .
• rm -rf dart
• cd vagrant
• git clone https://github.com/RetailMeNotSandbox/dart.git # this source code will be referenced by d-compose
• sudo pip install -r tools_requirements.txt # installs jinja so we can create d-compose files
• python generate_deployment_files.py # generates files from templates, a set for each part (engine, web, ...)
• cd docker_files
• sed -i 's|/vagrant_data/docker_files|.|g' docker-compose.yml
• sed -i 's|/vagrant_data|.|g' docker-compose.yml # removing prefixes since we will use the files in cur dir
• sed -i 's|/docker_files|.|g' docker-compose.yml
• git clone https://github.com/RetailMeNotSandbox/dart.git # the source code
• docker-compose up -d --build web postgres elasticmq # launch dependent containers first so we can init dart

Step 6: init DART database

STOP=1;
while [ $STOP -gt 0 ]; do
  sh -c 'docker-compose logs web | tail -10'
  docker-compose exec web curl -XPOST "http://127.0.0.1:5000/admin/create_all";
  STOP=$?;
  echo "Waiting for web worker to complete. Trying again in 15 seconds ..."
  sleep 15;
done

step 7: Launch the remaining DART components.

• docker-compose up -d --build engine trigger subscription
• docker-compose ps # to verify

Step 8: Add no-op engine so we can run unit tests.

STOP=1; 
while [ $STOP -gt 0 ]; do 
  docker-compose exec web python /tmp/src/python/dart/engine/no_op/add_engine.py; 
  STOP=$?; 
  sleep 1; 
done

step 9: Run unit tests.

• docker-compose exec web python -m unittest discover /tmp/src/python/dart/test/schema/ "test_*.py"
• docker-compose exec web python -m unittest discover /tmp/src/python/dart/test/graph "test_*.py"
• docker-compose exec web python -m unittest discover /tmp/src/python/dart/test/crud "test_*.py"

_Step 10__: Misc.

• Open port 5000 as a custom tcp rule (use my ip) then you can access this instance via browser
• open 5432 for sql and so on ..(see docker-compose file for ports)
