This article mainly explains "how to build and deploy zookeeper+kafka in docke swarm". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to build and deploy zookeeper+kafka in docke swarm.

1. Machine preparation

Prepare three machines, IP is 192.168.10.51,192.168.10.52,192.168.10.53; hostnames are centos51, centos52, centos53. Three machines are ready for the docker swarm environment. For docker swarm building, you can refer to another article, docker swarm cluster building.

two。 Prepare for mirroring.

Pull zookeeper, kafka and kafka manager related images on https://hub.docker.com/

Docker pull zookeeper:3.6.1docker pull wurstmeister/kafka:2.12-2.5.0docker pull kafkamanager/kafka-manager:3.0.0.4

3. Prepare zookeeper related compose.

File name: docker-stack-zookeeper.yml

Version: "3.2" services:#zookeeper Service zookeeper-server-a: hostname: zookeeper-server-an image: zookeeper:3.6.1 ports:-"12181 Asia/Shanghai ZOO_MY_ID 2181" networks: swarm-net: aliases:-zookeeper-server-an environment: TZ: Asia/Shanghai ZOO_MY_ID: 1 ZOO_SERVERS: server.1=zookeeper-server-a:2888:3888;2181 server.2=zookeeper-server-b:2888:3888 2181 server.3=zookeeper-server-c:2888:3888 2181 volumes:-/ data/kafka_cluster/zookeeper/data:/data deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos51] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory : 512m zookeeper-server-b: hostname: zookeeper-server-b image: zookeeper:3.6.1 ports:-"22181 ZOO_SERVERS 2181" networks: swarm-net: aliases:-zookeeper-server-b environment: TZ: Asia/Shanghai ZOO_MY_ID: 2 ZOO_SERVERS: server.1=zookeeper-server-a:2888:3888 2181 server.2=zookeeper-server-b:2888:3888;2181 server.3=zookeeper-server-c:2888:3888 2181 volumes:-/ data/kafka_cluster/zookeeper/data:/data deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos52] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory : 512m zookeeper-server-c: hostname: zookeeper-server-c image: zookeeper:3.6.1 ports:-"32181 ZOO_SERVERS 2181" networks: swarm-net: aliases:-zookeeper-server-c environment: TZ: Asia/Shanghai ZOO_MY_ID: 3 ZOO_SERVERS: server.1=zookeeper-server-a:2888:3888 2181 server.2=zookeeper-server-b:2888:3888;2181 server.3=zookeeper-server-c:2888:3888 2181 volumes:-/ data/kafka_cluster/zookeeper/data:/data deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos53] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory : 512Mnetworks: swarm-net: external: name: swarm-net

4. Kafka related compose preparation

File name: docker-stack-kafka.yml

Version: "3.2" services:#kafka Service kafka-server-a: hostname: kafka-server-an image: wurstmeister/kafka:2.12-2.5.0 ports:-"19092 kafka-server-a: swarm-net: aliases:-kafka-server-an environment:-TZ=CST-8-KAFKA_ADVERTISED_HOST_NAME=kafka-server-a-HOST_IP=kafka- Server-a-KAFKA_ADVERTISED_PORT=9092-KAFKA_ZOOKEEPER_CONNECT=zookeeper-server-a:2181 Zookeeper-server-b:2181 Zookeeper-server-c:2181-KAFKA_BROKER_ID=0-KAFKA_HEAP_OPTS= "- Xmx512M-Xms16M" volumes:-/ data/kafka_cluster/kafka/data:/kafka/kafka-logs-kafka-server-a-/ data/kafka_cluster/kafka/logs:/opt/kafka/logs deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos51] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory: 512m kafka-server-b: hostname: kafka-server-b image: wurstmeister/kafka:2.12-2.5.0 ports:-"29092 ports" networks: swarm-net: Aliases:-kafka-server-b environment:-TZ=CST-8-KAFKA_ADVERTISED_HOST_NAME=kafka-server-b-HOST_IP=kafka-server-b-KAFKA_ADVERTISED_PORT=9092-KAFKA_ZOOKEEPER_CONNECT=zookeeper-server-a:2181 Zookeeper-server-b:2181 Zookeeper-server-c:2181-KAFKA_BROKER_ID=1-KAFKA_HEAP_OPTS= "- Xmx512M-Xms16M" volumes:-/ data/kafka_cluster/kafka/data:/kafka/kafka-logs-kafka-server-b-/ data/kafka_cluster/kafka/logs:/opt/kafka/logs deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos52] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory: 512m kafka-server-c: hostname: kafka-server-c image: wurstmeister/kafka:2.12-2.5.0 ports:-"39092 wurstmeister/kafka:2.12 9092" networks: swarm-net: Aliases:-kafka-server-c environment:-TZ=CST-8-KAFKA_ADVERTISED_HOST_NAME=kafka-server-c-HOST_IP=kafka-server-c-KAFKA_ADVERTISED_PORT=9092-KAFKA_ZOOKEEPER_CONNECT=zookeeper-server-a:2181 Zookeeper-server-b:2181 Zookeeper-server-c:2181-KAFKA_BROKER_ID=2-KAFKA_HEAP_OPTS= "- Xmx512M-Xms16M" volumes:-/ data/kafka_cluster/kafka/data:/kafka/kafka-logs-kafka-server-c-/ data/kafka_cluster/kafka/logs:/opt/kafka/logs deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos53] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory: 512Mnetworks: swarm-net: external: name: swarm-net

5. Preparation of kafka manager related compose

File name: docker-stack-kafka-manager.yml

Version: "3.2" services:#kafka manager Service kafka-manager: hostname: kafka-manager image: kafkamanager/kafka-manager:3.0.0.4 ports:-"19000 kafka-manager image 9000" networks: swarm-net: aliases:-kafka-manager environment:-ZK_HOSTS=zookeeper-server-a:2181,zookeeper-server-b:2181 Zookeeper-server-c:2181 deploy: replicas: 1 restart_policy: condition: on-failure placement: constraints: [node.hostname = = centos51] resources: limits:# cpus:'1' memory: 1GB reservations:# cpus: '0.2' memory: 512Mnetworks: avatar-net: external: name: swarm-net

6. Create file mapping paths on three machines

Mkdir-p {/ data/kafka_cluster/zookeeper/data,/data/kafka_cluster/kafka/data,/data/kafka_cluster/kafka/logs} chown-R 777 / data/kafka_cluster/

7. Execute compose

Be sure to execute in order, and then execute the next command successfully.
