RabbitMQ with AMQPS and MQTTS with LetsEncrypt

Introduction

RabbitMQ with AMQPS and MQTTS with automatic renewal of certificates from LetsEncrypt in Docker. This repository can use a dns-mapper to facilitate automatic wildcard dns hostname creation like http://xip.io or http://nip.io for each docker-container specified in the docker-compose.

Start

Start AMQPS on port 5671, MQTTS on port 8883 and the management interface of RabbitMQ on port 443:

DNS_MAPPER=nip.io IP_ADDRESS=12.34.56.78 docker-compose up

Test HTTPS

Open a browser to https://rabbitmq.12.34.56.78.nip.io and check that you see the RabbitMQs management interface and that it has a valid SSL certificate.

Test AMPQPS

docker-compose exec rabbitmq bash -c \
 'openssl s_client -connect ${IP_ADDRESS}:5671 \
  -CAfile /var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/chained.pem \
  -cert   /var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/signed.crt  \
  -key    /var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/domain.key'

Test MQTTS

docker-compose exec rabbitmq bash -c \
 'openssl s_client -connect ${IP_ADDRESS}:8883 \
  -CAfile /var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/chained.pem \
  -cert   /var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/signed.crt  \
  -key    /var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/domain.key'

rabbitmq.conf

The rabbitmq.conf loads the the following certificates from https://github.com/SteveLTN/https-portal

[
 {ssl, [{versions, ['tlsv1.2', 'tlsv1.1']}]},
 {rabbit, [
  {ssl_listeners, [5671]},
  {ssl_options, [
   {cacertfile,"/var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/chained.pem"},
   {certfile,  "/var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/signed.crt"},
   {keyfile,   "/var/lib/https/rabbitmq.${IP_ADDRESS}.${DNS_MAPPER}/production/domain.key"},
   {versions, ['tlsv1.2', 'tlsv1.1']} 
  ]},
  {loopback_users, []}
 ]},
 {rabbitmq_mqtt, [
  {ssl_listeners,    [8883]},
  {tcp_listeners,    [1883]}
 ]}
].
