Finishing set up

Docker, HAProxy, Git

sudo yum install docker -y
sudo service docker start
sudo yum install haproxy -y
sudo yum install git -y

There is no further configuration needed here.

Installing Nodejs and NPM

You need Nodejs and NPM in order to install Nodejs packages and start Manticore. Here are the instructions for installing NVM, which can easily install different version of Nodejs for you.

# See https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-a-centos-7-server
curl -sL https://raw.githubusercontent.com/creationix/nvm/master/install.sh -o install_nvm.sh
bash install_nvm.sh
source ~/.bash_profile

Now do nvm ls-remote to see available versions and run

nvm install <version string>
nvm use <version string>
nvm alias default <version string>

Setting up consul-template

You can download it here. consul-template has the responsibility of using Consul to generate the HAProxy configuration file. You will need consul-template running on every machine with HAProxy and Manticore. The template and settings files for HAProxy can be found in the Manticore Github repository here.

Running consul-template in the background:

sudo consul-template -config <location of template-settings.hcl> &

You may need to give ownership of /etc/haproxy/ and the configuration file within depending on how you run consul-template

Domain names

If you're using HAProxy, you need a domain name that Manticore can use in order to set up custom external urls. This may involve using Route 53 to get a domain name. Ensure that you have a domain name you can use to point to either an Elastic Load Balancer which points to your API machine or to point to your API machine directly.

Now we are ready to start Manticore
