Deploy on Amazon EC2

Deploy Graph Explorer onto an Amazon EC2 instance and use it as a proxy server with SSH tunneling to connect to Amazon Neptune.

Prerequisites

Provision an Amazon EC2 instance that will be used to host the application and connect to Neptune as a proxy server. For more details, see instructions here.
Ensure the Amazon EC2 instance can send and receive on ports 22 (SSH), 8182 (Neptune), and 443 or 80 depending on protocol used (graph-explorer).
Docker installed on the EC2 instance
AWS CLI installed on the EC2 instance

aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws

Pull the Docker image
```
docker pull public.ecr.aws/neptune/graph-explorer
```
If you receive an error relating to the docker service not running, run service docker start.
Run the container substituting the {hostname-or-ip-address} with the hostname or IP address of the EC2 instance
```
docker run -p 80:80 -p 443:443 \
 --restart unless-stopped \
 --env HOST={hostname-or-ip-address} \
 public.ecr.aws/neptune/graph-explorer
```
The --restart unless-stopped flag ensures the container automatically restarts after a host reboot or if the container crashes. See Docker’s restart policy documentation for other options.
Navigate to the public URL of your EC2 instance accessing the /explorer endpoint. You will receive a warning as the SSL certificate used is self-signed. The URL will look like this:
```
https://ec2-1-2-3-4.us-east-1.compute.amazonaws.com/explorer
```
Since the application is set to use HTTPS by default and contains a self-signed certificate, you will need to add the Graph Explorer certificates to the trusted certificates directory and manually trust them. See HTTPS Connections section.
After completing the trusted certification step and refreshing the browser, you should now see the Connections UI.
