                      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:

                      apiVersion: apps/v1
                      kind: Deployment

                      The image rocketmq:4.9.3-alpine was created following the procedure on the apache/rocketmq-docker repo.

                      After the deployment the rocketmq-namesrv works, but the broker's pod logs: sh: can't open 'mqbroker': No such file or directory. ut if I try to run manually the container with kubectl run -ti rocketmq-broker --image=myrepo/rocketmq:4.9.3-alpine --restart=Never -- sh mqbroker -n localhost:9876 it works...

                      What could it be the problem in the yaml? Am I making something wrong?

                      I think the problem is with the mount path.

                              - name: broker-store
                                mountPath: /home/rocketmq
                      

                      So your binaries won't be there and so the error

                      Vulnerabilities

                      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.

                      Install RocketMQ

                      You can download it from GitHub.
                      You can use RocketMQ like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the RocketMQ component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
