Guide to Deploy RocketMQ on Akash

This guide will help you deploy Apache RocketMQ on Akash, leveraging the official Docker image. RocketMQ is a distributed messaging and streaming platform. The steps include creating an SDL file for Akash, setting up the RocketMQ broker and nameserver, and deploying them on Akash.

Prerequisites

1. Akash CLI Installed: Make sure you have the Akash CLI installed and configured.
2. Docker Image: Use the official RocketMQ Docker image: apache/rocketmq:latest.
3. Akash Account: Ensure you have AKT tokens and are ready to deploy.
4. Ports Used:
   • Nameserver: 9876
   • Broker: 10911, 10912 (communication) and 10909 (Web access)

Step 1: Prepare the Akash SDL File

The SDL (Stack Definition Language) file describes your deployment. Here’s an example rocketmq-deployment.yml for deploying RocketMQ’s nameserver and broker:

version: "2.0"

services:
  rocketmq-nameserver:
    image: apache/rocketmq:latest
    args: ["sh", "-c", "mqnamesrv"]
    env:
      - JAVA_OPT=-Duser.timezone=UTC
    expose:
      - port: 9876
        as: 9876
        to:
          - global: true

  rocketmq-broker:
    image: apache/rocketmq:latest
    args: ["sh", "-c", "mqbroker -n rocketmq-nameserver:9876"]
    env:
      - JAVA_OPT=-Duser.timezone=UTC
      - BROKER_ID=0
      - BROKER_NAME=broker-a
      - NAMESRV_ADDR=rocketmq-nameserver:9876
    expose:
      - port: 10909
        as: 10909
        to:
          - global: true
      - port: 10911
        as: 10911
        to:
          - global: true
      - port: 10912
        as: 10912
        to:
          - global: true

profiles:
  compute:
    rocketmq-nameserver:
      resources:
        cpu:
          units: 500m
        memory:
          size: 512Mi
        storage:
          size: 1Gi
    rocketmq-broker:
      resources:
        cpu:
          units: 1
        memory:
          size: 1Gi
        storage:
          size: 2Gi

deployment:
  rocketmq:
    rocketmq-nameserver:
      profile: rocketmq-nameserver
      count: 1
    rocketmq-broker:
      profile: rocketmq-broker
      count: 1

Step 2: Validate the SDL File

Run the following command to validate the SDL file syntax:

akash validate --manifest rocketmq-deployment.yml

If there are errors, correct them before proceeding.

Step 3: Deploy RocketMQ on Akash

1. Create the Deployment:

   Submit the deployment to Akash:

   akash tx deployment create rocketmq-deployment.yml --from <your-account> --gas auto --gas-prices 0.0025uakt

2. Check for Bids:

   Monitor bids from providers using:

   akash query market bid list --owner <your-address>

3. Accept a Bid:

   Once you find a suitable bid, accept it:

   akash tx market lease create --owner <your-address> --provider <provider-address> --dseq <deployment-sequence> --from <your-account>

Step 4: Access RocketMQ

Once deployed, you can access RocketMQ’s services globally using the assigned domain or IP and the following ports:

1. Nameserver: <IP>:9876
2. Broker Web UI: <IP>:10909
3. Broker Communication: Ports 10911 and 10912.

Step 5: Test RocketMQ

1. Install the RocketMQ Client on your local machine or server.
2. Configure the NAMESRV_ADDR to point to the Akash deployment: <IP>:9876.
3. Use RocketMQ’s CLI or SDKs to produce and consume messages to ensure everything is working.

Step 6: Monitor and Manage RocketMQ

• Check logs by accessing the container logs using Akash CLI.
• Update the deployment if needed by modifying the SDL and resubmitting the deployment.

Optional Enhancements

• Persistent Storage: Add persistent storage for message logs.
• Scaling: Use Akash profiles to scale the broker or nameserver.
• Secure Access: Add reverse proxy or VPN to secure RocketMQ services.

This guide provides a straightforward method to deploy RocketMQ on Akash using the official Docker image.
