Install the docnow application

Ansible Installer the Docnow App



The goal of this repository is to set up docnow/docnow tool.


On Ubuntu

cd ~
mkdir bin
cd bin
sudo apt-get update
sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible

Your versions may differ from the terraform examples presented above. Please note that this code was written for Terraform 0.11.7

On MacOS

brew install terraform ansible

Your versions may differ from the terraform examples presented above. Please note that this code was written for Terraform 0.11.7


Your own infrastructure

If you intend to run this on your own infrastructure, you will need a Docker Host and Docker compose installed on the host. It is recommended that you set up a reverse proxy web server ideally with TLS. Your reverse proxy server will listen on port 3000 for the docnow application

Clone the docnow repo

git clone

From the cloned repo review the docker-compose.yml file and adjust accordingly. Specifically determine where you plan to host your elasticsearch and redis. Then run

docker-compose up -d


Please note that this example will deploy real resources into your AWS account. We have made every effort to ensure all the resources qualify for the AWS Free Tier, but we are not responsible for any charges you may incur.

Configure your AWS access keys as environment variables:

From your AWS access keys above you will need to create AWS services. Enter the generated keys on a file named ~/.aws/credentials

cat ~/.aws/credentials
aws_access_key_id = GENERATEDAWSKEYABOVE
aws_secret_access_key = randomstringofcharactersgeneratedabove

We will also need to create an ssh key that we will use to log into our created EC2 instances


In order to log into your EC2 instance terraform will upload your ssh keys to your AWS. To generate your keys

ssh-keygen -t rsa -C "docnow_key" -f ./docnow_key

then add them to your sessions with

ssh-add -K docnow_key

Copy hosts_example to hosts in the staging directory and then copy docker-compose.yml-example to docker-compose.yml in the docnow ansible role

Configuration Options

How it works

When all this is done create your AWS infrastructure from the staging or production directory under the terraform_* environment you would like to build

terraform init

This will initialize the repo and pull the correct terraform plugins

terraform get

This will build your docnow, elastic, and networking modules

terraform plan

where you will be prompted for the number of VMs you plan to have

terraform apply

Which repeats the same step as plan but creates your infrastructure. The process will complete with information we will need for our ansible playbook.

The output for

  • docnow_ip, redis_ip, and elastic_ip will be added to the hosts file
  • elastic_ip and redis_ip will also be added to the docker-compose.yml file
  • bastion_host will be appended to your ~/.ssh/config file
  • elb_hostname will be the URI to point to

The repo has examples of ssh_config and hosts_example above

Then run the playbook to complete the application

ansible-playbook ansible/deploy.yml -b

When this is done your playbook will list the IP of the completed end point to log into. Below is an example of a completed play.

In that example pointing your browser to the elb_hostname variable

will lead you to your application.
