If you want to run a zookeeper cluster you have to start with at least 2
members. From there you can scale up with the dynamic reconfig commands.

I am experimenting with zk and the reconfig feature and trying to
understand if I can start a single zk node and then reconfig/bootstrap the
other 2 nodes into the ensemble. The reconfig command is throwing an error
that there isn't a quorum yet. Is this line of thinking possible? or do I
need to setup the first 3 nodes manually the first time?
I am basing this experiment off of this web page.
https://blog.container-solutions.com/dynamic-zookeeper-cluster-with-docker
/opt/zookeeper/zookeeper/bin/zkCli.sh -server 10.1.1.104:2181 reconfig -add
"server.2=10.1.1.40:2888:3888:participant;2181"
No quorum of new config is connected and up-to-date with the leader of last
commmitted config - try invoking reconfiguration after new servers are
connected and synced
/opt/zookeeper/zookeeper/bin/zkCli.sh -server 10.1.1.104:2181 config
server.1=10.1.1.104:2888:3888:participant;0.0.0.0:2181
cat ./zoo.cfg
autopurge.purgeInterval=1
initLimit=10
syncLimit=5
autopurge.snapRetainCount=6
tickTime=2000
dataDir=/mnt/zookeeper/data
reconfigEnabled=true
standaloneEnabled=false
dynamicConfigFile=/opt/zookeeper/zookeeper/conf/zoo.cfg.dynamic.1600000000
What is the best solution for an unattended bootstrap setup of a new
cluster from scratch?
This was something that we were able to accomplish with exhibitor on older
versions of zookeeper in the past.
