TLS Support

To enable TLS, you need to set the following properties in your application.yml file:

spring:
  rabbitmq:
    ssl:
      enabled: true
      trust-store: classpath:docker/rabbitmq/certs/keystore.p12
      trust-store-password: changeit
      trust-store-type: PKCS12

Use below commands to generate RabbitMQ certificates

mkdir -p certs && cd certs
# CA key and certificate
openssl genrsa -out ca.key 2048
openssl req -x509 -new -nodes -key ca.key -sha256 -days 1024 -out ca.crt -subj "/CN=MyCA"

# Server key and certificate signing request
openssl genrsa -out server.key 2048
openssl req -new -key server.key -out server.csr -subj "/CN=localhost"

# Sign the server cert with the CA
openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial \
-out server.crt -days 365 -sha256

Trust Store

keytool -import -alias rabbitmq -file ca.crt -keystore keystore.p12 -storetype PKCS12 -storepass changeit
