Implementing secure service communication with TLS
In this section, we are going to demonstrate how to establish secure client-server communication for our services using a TLS protocol. To do so, we are going to generate a digital test certificate that we will use via our microservices. Then, we will update the server and client code of our microservices so that they can use the certificate data to verify each other’s identities and secure communication between them.
Let’s begin the TLS onboarding process by following these steps:
- First, let’s generate a test certificate and a private key file that we will use to authenticate our services:
...openssl req -x509 -nodes -newkey rsa:4096 \ -keyout server.key -out server.crt -days 365 -nodes \ -subj "/C=US/ST=State/L=City/O=Organization/OU=Department/CN=localhost" \ -addext "subjectAltName=DNS:localhost,DNS:example.com,IP:127.0.0.1,IP:192.168.1.1" -config /dev/null
