This article mainly introduces "how to use docker to build kafka environment". In daily operation, I believe many people have doubts about how to use docker to build kafka environment. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to use docker to build kafka environment". Next, please follow the editor to study!

Recently, I learned about kafka. In order to facilitate the construction of the environment, I used docker for deployment.

You need to install the environment of docker first. Requires the operating system to be a linux 64-bit system.

Installation of docker (suitable for rpm/deb installation):

Curl-fsSL https://get.docker.com/ | sh

Installation of docker-compose:

Curl-L https://github.com/docker/compose/releases/download/1.7.0/docker-compose-`uname-s`-`uname-m` > / usr/local/bin/docker-composechmod + x / usr/local/bin/docker-composeKafka Image

Dockerfile

Dockerfile is used to describe the production process of an image. Write the corresponding Dockerfile according to kafka's tutorials.

The basic image uses the version of centos6, but other versions can be used as needed.

FROM index.alauda.cn/tutum/centos:centos6RUN yum install-y wgetRUN wget-- no-check-certificate-- no-cookies-- header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u91-b14/jdk-8u91-linux-x64.rpmRUN rpm-ivh jdk-8u91-linux-x64.rpmRUN mkdir-p / kafka & & cd / kafka & & wget http://mirrors.cnnic.cn/apache/kafka/0.9.0.0 / kafka_2.11-0.9.0.0.tgz & & tar-xzf kafka_2.11-0.9.0.0.tgz & & cd kafka_2.11-0.9.0.0WORKDIR / kafka/kafka_2.11-0.9.0.0

With such a Dockerfile, you can mirror it locally or using the public cloud. If you make it locally, you can use this command:

Docker build-t index.alauda.cn/xuxinkun/kafka.

I used Lingqueyun's mirror service for build, which can be viewed here.

Docker-Compose

Now that you have the mirror, you need to start the service. Here, docker's orchestration service docker-compose is used for choreography.

Kafka mainly includes two services, zookeeper and kafka. So you need to start two services respectively. Here the two services will directly use the host network. Write the docker-compose.yaml as follows:

Zk: image: index.alauda.cn/xuxinkun/kafka net: host stdin_open: true tty: true command: bin/zookeeper-server-start.sh config/zookeeper.propertieskafka: image: index.alauda.cn/xuxinkun/kafka net: host stdin_open: true tty: true command: bin/kafka-server-start.sh config/server.properties

Start the service

You can now start all services with one command:

[root@node1 Dockerfile] # docker-compose up-dCreating dockerfile_kafka_1Creating dockerfile_zk_1

View service status

View the status of the service.

[root@node1 Dockerfile] # docker-compose psName Command State Ports-dockerfile_kafka_1 bin/kafka-server-start.sh... Up dockerfile_zk_1 bin/zookeeper-server-start... Up

Of course, you can also use docker ps-a to view.

Out of Service

[root@node1 Dockerfile] # docker-compose stop zk kafkaStopping dockerfile_kafka_1... DoneStopping dockerfile_zk_1... Done

Delete a service

[root@node1 Dockerfile] # docker-compose rm zk kafka at this point, the study on "how to use docker to build a kafka environment" is over. I hope I can solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
