Run your Docker image on AWS EC2 via systemd

1. Start new EC2 instance running Debian Stretch via AWS cli (or AWS Console)



aws ec2 run-instances --image-id ami-8bb70be4 --instance-type c4.large --key-name X

2. Get public ip (or use AWS Console)

aws ec2 describe-instances

3. Install Docker

ssh admin@>>>IP-from-step-2<<<
sudo -i

apt-get update
apt-get install -y \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg2 \
    software-properties-common

curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg | apt-key add -
add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \
  $(lsb_release -cs) \
  stable"

apt-get update
apt-get install -y docker-ce

systemctl status docker

# Register at https://hub.docker.com/ first
docker login

4. Install systemd-docker

curl -L https://github.com/ibuildthecloud/systemd-docker/releases/download/v0.2.1/systemd-docker -o /usr/local/bin/systemd-docker
chmod +x /usr/local/bin/systemd-docker

5. Start postgresql & redis Docker containers



docker run -d -p 5432:5432 -e POSTGRES_USER=user -e POSTGRES_PASSWORD=pass -e POSTGRES_DB=dbname --name db postgres:9.6.5


docker run -d -p 6379:6379 --name redis redis:3.2.6

6. Create systemd service

exit  # exit root
exit  # exit EC2 instance & return to host
scp systemd/docker_polycon_app.service systemd/polycon.env admin@>>>IP-from-step-2<<<:
ssh admin@>>>IP-from-step-2<<<
sudo -i
mkdir /etc/docker-container
mv /home/admin/polycon.env /etc/docker-container
mv /home/admin/docker_polycon_app.service /etc/systemd/system

6. Start systemd service & create database schema

systemctl start docker_polycon_app
systemctl status docker_polycon_app

docker exec docker_polycon_app.service bin/console doctrine:schema:create

7. Open browser
