QUESTION

Binary not found in Kubernetes deployment

Asked 2022-Mar-09 at 11:23

I'm trying to deploy rocketmq on my testing cluster. I started from the scripts provided in the apache/rocketmq-docker repo on github, but they do not work. I created my own yaml deployment starting from the one in the repo I previously cited, and it works for mqnamsrv, but not for broker. In the following the 2 deployments:

QUESTION

Design k8s app which get data from external source and send to same destination

Asked 2021-Sep-28 at 17:22

I have an app that get data from a third-party data source, it will send data to my app automatically and I can't filter it, I can only receive all. When data arrive, my app will transmit this data to a rocketmq topic.

Now I have to make this app a container and deploy it in k8s deployment with 3 replica. But these pods will all get same data and send to the same rocketmq topic.

How do I make this app horizontal scalable without sending duplicate msg to the same rocketmq topic?

There is no request. My app connect to a server and it will send data to app by TCP. Every Pod will connect to that server.

If you want to do this with more than one instance, they need to coordinate in some way.

Leader Election pattern is a way to run multiple instances, but only one can be active (e.g. when you read from the same queue). This is a pattern to coordinate - only one instance is active at the time. So this pattern only use your replicas for higher availability.

If you want that all your replicas actively work, this can be done with techniques like sharding or partitioning. This is also how e.g. Kafka (e.g. similar to a queue) makes concurrent work from queues.

There are other ways to solve this problem as well, e.g. to implement some form of locks to coordinate - but partitioning or sharding as in Kafka is probably the most "cloud native" solution.

I am afraid that you are wrong.

RocketMQ does not support ttl which means the message will NOT be deleted controlled by a client parameter, though the message will be indeed deleted after a period of time(for example 7 days).

So if you need to implement a ttl like consuming, you should do it in your consumer like:

Vulnerabilities

CVE-2019-17572 MEDIUM

In Apache RocketMQ 4.2.0 to 4.6.0, when the automatic topic creation in the broker is turned on by default, an evil topic like “../../../../topic2020” is sent from rocketmq-client to the broker, a topic folder will be created in the parent directory in brokers, which leads to a directory traversal vulnerability. Users of the affected versions should apply one of the following: Upgrade to Apache RocketMQ 4.6.1 or later.
