Setting up a CentOS 7 machine for use with Convergence

We recommend a t3.large (specs) or equivalent instance at minimum. If on AWS, use the CentOS Linux 7 x86_64 HVM EBS ENA 1803 AMI.

Ports

TCP ports 443 (and optionally 80) should accept inbound TCP traffic.

Install Docker and docker-compose

You may need to use sudo with many of these commands.

# Add the Docker repo 
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

# Install Docker and its dependencies
yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2 \
  docker-ce \
  epel-release

# Allow the new `docker` user to run commands without sudo
usermod -aG docker centos

# Start up docker
systemctl start docker

# Install docker-compose with PIP, a Python package manager
yum upgrade -y python*
yum install -y python-pip
pip install docker-compose

# Bump up memory allocation for elasticsearch
sudo sysctl -w vm.max_map_count=262144

At this point, Docker and docker-compose should be running. Execute docker and docker-compose to make sure they were installed properly.
