Navigate to the VPC Dashboard in the AWS Management Console and create a new VPC. Finally, we will SSH into the EC2 instance, install the Postgres client psql, create a table on the RDS instance, and install and set up an SSH tunnel. An EC2 instance will be provisioned in the public subnet with an attached security group that only allows inbound SSH traffic from your local IP and all outbound traffic. A Postgres RDS instance will be provisioned in the private subnet with an attached security group that only allows inbound traffic on port 5432 from the public subnet. The public subnet will have a custom route table that includes the local route as well as a route directing all other traffic over the Internet gateway. The VPC will have an Internet gateway attached, however the main route table will contain only a single local route that enables communication within the VPC. We will create a VPC with 2 subnets in the us-west-1 region 1 public subnet in the us-west-1a availability zone and 1 private subnet in the us-west-1b availability zone. The following diagram depicts what our final architecture will look like. This allows you to connect Chartio to a database in your private VPC subnet without modifying its route table or security groups.
You may change the value of the key at any time, resulting in a termination of all active sessions.In this tutorial, we will walk through setting up an Amazon RDS instance inside a private VPC subnet and connecting to it using an SSH tunnel.Ī reverse SSH tunnel makes an outbound encrypted connection from within your VPC to Chartio’s servers. It should be at least 50 characters long and should not be shared outside the configuration file. SECRET_KEY specifies a secret cryptographic key that is used to improve the security of cookies and password resets. For more information about advanced Redis configuration, you may refer to the official documentation. For most installations the default configuration is good enough and you can leave it as it is. REDIS specifies the configuration parameters of Redis, an in-memory key-value store required as part of the NetBox installation.
