我正在尝试使用 docker 来测试我们的 Kafka 监听器

两台服务器似乎都能正常启动,因为我能够运行命令

docker exec -it bsbecpromoeventservice_broker_run_ping zookeeper
PING zookeeper (172.20.0.2): 56 data bytes
64 bytes from 172.20.0.2: icmp_seq=0 ttl=64 time=0.089 ms
64 bytes from 172.20.0.2: icmp_seq=1 ttl=64 time=0.193 ms
64 bytes from 172.20.0.2: icmp_seq=2 ttl=64 time=0.201 ms
^C--- zookeeper ping statistics ---

但是当我尝试运行以下命令时

docker exec -it bsbecpromoeventservice_broker_run_4 kafka-topics --create --zookeeper zookeeper:2 -replication-factor 1 --partitions 1 --topic test

我明白了

[2017-09-13 15:22:43,967] WARN Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect (org.apache.zookeeper.ClientCnxn)

这是我的 docker-compose 文件

如何让 Kafka 服务器能够创建主题?

最佳答案

创建主题的容器运行命令

使用容器命令docker run --net=host --rm。在下面的示例中,zookeeper 在端口 22181 上运行,请使用相应的主题名称、端口。

创建

docker run   --net=host   --rm   confluentinc/cp-kafka:4.0.0   kafka-topics --create --topic customer --partitions 1 --replication-factor 1 --if-not-exists --zookeeper  localhost:22181

描述

docker run   --net=host   --rm   confluentinc/cp-kafka:4.0.0   kafka-topics --zookeeper localhost:22181 --topic customer --describe

列表

docker run   --net=host   --rm   confluentinc/cp-kafka:4.0.0   kafka-topics --list --zookeeper  localhost:22181

删除

docker run   --net=host   --rm   confluentinc/cp-kafka:4.0.0   kafka-topics  --delete --topic customer --zookeeper localhost:22181
