MQ Adapter

Integration using Apache Cammel to connect IBM MQ systems to SQS, SNS and/or Amazon MQ.

Architecture

You can setup multiple Apache Camel clusters to perform different IBM MQ integrations.

Using Amazon SNS to receive messages

Amazon SNS

Using Amazon SQS to send messages

Amazon SQS

Using Amazon MQ to send and receive messages

Recommended when migrating existing applications or need to rely in industry standards protocols (AMQP, MQTT, STOMP, etc).

Amazon MQ

Requirements

You need to have the following dependencies in place for the deployment:

  • AWS Account (It's recommended to have one per environment such as development, integration and production)
  • Mac OS / Cloud9 with Amazon Linux 2 Platform
  • Bash/ZSH terminal
  • Docker version > 20.10.x
  • aws-cli v2 here
  • AWS credentials and profiles for each environment under ~/.aws/config here
  • Node v16.14.* && NPM v8.11.*
  • yarn v1.x e.g: 
      npm install --global yarn

Getting Started

1. Boostrapping

Prerequisites

The following credentials are needed for client to connect to MQ:

  • TrustStore
  • TrustStorePassword
  • KeyStore
  • KeyStorePassword

Boostrap

Boostrap

  1. Make sure you have the correct AWS_PROFILE and AWS_REGION environment variables. In case you have the latest version of Docker Desktop in your MacOs then make sure to export the following environment variables as well: export DOCKER_BUILDKIT=0 export COMPOSE_DOCKER_CLI_BUILD=0
  2. Run yarn cdk bootstrap --qualifier mq to boostrap CDK within each of your AWS account.
  3. If using Amazon MQ as target, setup resource policy for Amazon MQ to publish Cloudwatch Logs: aws logs put-resource-policy --policy-name AmazonMQ-logs --policy-document '{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "mq.amazonaws.com" }, "Action":[ "logs:CreateLogStream", "logs:PutLogEvents" ], "Resource" : "arn:aws:logs:*:*:log-group:/aws/amazonmq/*" } ] }'
  4. Run yarn install to install CDK dependencies

Creating secrets

  1. Generate the x509 certificates and AWS Secrets running the following commands under app folder:
cd app
# Generates X509 certificates
./deploy.sh generate_secrets
# Setup Secrets required for Camel broker (Replace <integration-name> with for example, dev)
./deploy.sh create_secrets broker <integration-name> 
# Setup Secrets for IBM MQ mock
./deploy.sh create_secrets mock

IMPORTANT: Update cdk.json with the "ARN" from the commands above.

Note: When running production, before running the scriptssetup the following environment variables TARGET_KEYSTORE_PASS and TARGET_TRUSTSTORE_PASS to random secure values before running the scripts for production.

You can skip last command if you're not deploying an IBM MQ Fargate mock (for example in a production enviroments).

(Optional) Updating secrets

  1. You can always upload new version of AWS Secrets using:
cd app
# Upload local secrets for broker
./deploy.sh update_secrets broker $integration-name
# Upload local secrets for IBM MQ mock
./deploy.sh update_secrets mock

2. Set up configuration

  1. Configure context (cdk.json) to specify environment and routes to enable (SQS, SNS or Amazon MQ). Example below:
"dev": {
      "accountId": "0123456788912",
      "region": "eu-west-1",

          }
        }
      }
    },
  1. Configure defaultVpcId with an existing vpc ID. If you're integrating to Amazon MQ, you also need to configure a hostedZone parameter.

Note: Separate integrations per channel to avoid Camel clusters noisy neighbours operations between routes (for example, request / response channels). This also supports better use of autoscaling functionality.

3. Deploying

  1. Run yarn cdk deploy '*-dev' --qualifier mq to deploy solution in dev environment.

How to access IBM MQ and Amazon MQ consoles

You can use a script to establish tunnels to both IBM MQ Mock or Amazon MQ and connect to their respective web consoles and send messages manually. You can test/connect.sh script. Make sure your AWS_PROFILE and AWS_REGION environment variables are set (export AWS_PROFILE='<ENTER_YOUR_CONFIGURED_AWS_PROFILE>'´).

You need to setup the following environment variables for it to work:

  • IBM_ENDPOINT: Endpoint for IBM MQ. Example: Network Load Balancer for IBM Mock (e.g mqmoc-mqada-1234567890.elb.eu-west-1.amazonaws.com)
  • AMAZONMQ_ENDPOINT: Endpoint for Amazon MQ (e.g b-12345678-abcd-1234-abcd-abcd12345678-9.mq.eu-west-1.amazonaws.com)
  • BASTION_ID: Instance ID for bastion (e.g i-abcd234567890abcd)

You can then log in to the console over https://127.0.0.1:8162/ or https://127.0.0.1:9443/ (if connecting to mock). For more information abut port forwarding: https://aws.amazon.com/de/blogs/mt/amazon-ec2-instance-port-forwarding-with-aws-systems-manager/.

You can login to the MQ Manager console https://localhost:9443/admin with password stored under mqAdapterIbmMockAdminPassword.

Login to Amazon MQ console (https://localhost:8162) with camel user name and the password stored in AWS Secrets Manager under amazonMQPassword.

How to test locally

Make sure your AWS_PROFILE environment variables are set so local application and IBM MQ retrieve secrets and publish/subscribe to events. Run start.sh run to start both app and IBM MQ using docker-compose up ibm-mq-mock.

Local tests require that routes are using either public routable services such as S3 or to configure a SSH tunnel through bastion (using connect.sh) to a private Amazon MQ. In the second case, configure your local DNS pointing AMAZONMQ_ENDPOINT to 127.0.0.1 to support SSL authentication.

YOu can also run camel from console or IDE using maven with following command line: camel:run -Dcom.ibm.mq.cfg.useIBMCipherMappings=false

Check Camel app's README.md to see the variables you need to configure.

How to test

When integrating to AmazonMQ

  1. In the IBM MQ console, access the local queue manager QM1 and under the corresponding DEV.QUEUE.
  2. Send a message using Hello AWS to the IBMMQ_REQUEST_QUEUE. This message will be processed by AWS Fargate and published to Amazon MQ.
  3. Access Amazon MQ console using connect.sh (https://localhost:8162) with camel user name and the password stored in AWS Secrets Manager under amazonMQPassword. Verify the message arrived in the corresponding AMAZONMQ_REQUEST_QUEUE queue specified in cdk.json.
  4. From Amazon MQ console, under Queues, select Send To to send a new message to the queue with: "Welcome to MQ Integration" message in the AMAZONMQ_RESPONSE_QUEUE queue.
  5. Verify the message has arrived in the corresponding IBMMQ_RESPONSE_QUEUE in IBM MQ.

When sending messages to SNS

  1. In the IBM MQ console, access the local queue manager QM1 and open the DEV.QUEUE under IBMMQ_REQUEST_QUEUE.
  2. Send a message using "Hello AWS". This message will be processed by AWS Fargate and published to SNS.
  3. Access the SQS console and choose the snsIntegrationStack prefix queue. This is an SQS queue subscribed to the SNS topic for testing.
  4. Select Send and receive message.
  5. Select Poll for messages to see the "Hello AWS" message previously sent from IBM MQ.

For reading messages from SQS

  1. Access the SQS console and choose the queue with the prefix sqsPublishIntegrationStack.
  2. Select Send and receive messages.
  3. For Message Body, add Hello from AWS.
  4. Choose Send message.
  5. In the IBM MQ console, access the local queue manager QM1 corresponding to IBMMQ_RESPONSE_QUEUE to find your message listed under this queue.

Adding new stages

  1. You can extend your cdk.json with new account stages such as int and prod.
    • Define Camel configuration per stage under app/resources/broker-<stage>.properties files.
    • For Amazon MQ, specify Active MQ configuration per stage under lib/conf/<stage>.xml
  2. Deploy via cdk deploy '*-dev --qualifier mq

Note: AWS recommends you to create a CDK pipeline using CDK Pipeline construct to manage changes in your environment.

Limitations

  • IBM MQ only supports mutual TLS authentication.
  • IBM MQ docker does not support M1 Link. Recommend a Cloud9 environment to deploy in that case.

FAQ

  • Where can I find Amazon MQ user credentials?

Credentials are stored in AWS Secrets Manager. There's a secret containing the admin MQ password (username: camel) and one for each integration configuration (specified under AMAZONMQ_CONSUMER_USERNAME).

  • Why do I need specify the credentials in each IBM MQ integration (dev-1, dev-2, dev-3)?

This enables you to integrate different IBM MQ clusters and use separate credentials between Camel clusters to reduce the blast radious.

  • Where can I find an example cdk.json for Amazon MQ configuration?

You can find the full examples to enable all Amazon SQS, SNS and MQ under cdk.json.full.

  • Where can I find Apache Camel's routes?

Camel routes are configured in app/src/main/resources/camel-context.xml file.
