How to disable Dynamic reconfig enabled while running in docker

[LahotiSourabh]

I am try to disable Dynamic Reconfig while running zookeeper on docker as this is causing issue while running zookeeper and Solr on AWS ECS Fargate environment.

Running environment: Docker Image: Zookeeper:latest version Docker Image: Solr 8.6 version Docker compose file: zoo1: image: zookeeper:latest

container_name: zoo1

restart: always
hostname: zoo1
ports:
  - 2181:2181
volumes:
  - ./data/zoo-1/data:/data
  - ./data/zoo-1/conf:/conf
  - ./data/zoo-1/datalog:/datalog
environment:
  ZOO_MY_ID: 1
  ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
  ZOO_4LW_COMMANDS_WHITELIST: "*"

solr3: image: solr:8.2 ports:

• "8983:8983" environment:
  • ZK_HOST=zoo1:2181,zoo2:2181,zoo3:2181 depends_on:
  • zoo1
  • zoo2
  • zoo3 volumes:
  • ./data/solr3/data:/var/solr

Please find attached screen shot that contain error - It looks like zookeeper is updating solr with zookeeper cluster server details that is configured as ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181

I'm not sure if the issue is related to the Docker image itself. Starting from 3.5.3 dynamic reconfiguration feature is disabled by default (see https://zookeeper.apache.org/doc/r3.6.2/zookeeperReconfig.html). This is also true for this Docker image.

If you want to try setting some additional configuration parameters that are not covered by the image environment variables you can use ZOO_CFG_EXTRA environment variable for that. See https://hub.docker.com/_/zookeeper/:

Also, it may worth reaching up upstream maintainers: https://issues.apache.org/jira/projects/ZOOKEEPER

Closing it because the issue seems to be inactive for quite some time now.
