[Docker] zookeeper+kafka+springboot实践1

某郑姓同学最近在对接该系统，之前没有用linux实践过，这次刚好借这个机会学习下。

• 环境

系统 Manjaro 20.2 Nibia 内核 Kernel: x86_64 Linux 5.9.8-2-MANJARO

Docker：

Client:
 Version:           19.03.13-ce
 API version:       1.40
 Go version:        go1.15.2
 Git commit:        4484c46d9d
 Built:             Sat Sep 26 12:04:46 2020
 OS/Arch:           linux/amd64
 Experimental:      false

docker-compose:

[ya@ya-PC zookeep]$ docker-compose version
docker-compose version 1.27.4, build unknown
docker-py version: 4.3.1
CPython version: 3.8.6
OpenSSL version: OpenSSL 1.1.1h  22 Sep 2020

防火墙：关闭

• docker网络

sudo docker network create --driver bridge --subnet 172.69.0.0/25 --gateway 172.69.0.1  kafka_zoo

• etc/hosts修改

sudo sh -c 'echo "172.69.0.11 broker1" >> /etc/hosts'
sudo sh -c 'echo "172.69.0.12 broker2" >> /etc/hosts'
sudo sh -c 'echo "172.69.0.13 broker3" >> /etc/hosts'
sudo cat /etc/hosts

• 创建 docker-compose.yml 随便找个目录，以~/kafka为例子

mkdir ~/kafka
cd ~/kafka
echo '' > docker-compose.yml

将底下的代码复制到docker-compose.yml中

• 后台启动并运行所有容器

cd ~/kafka
sudo docker-compose up -d

如果你之前没有运行过容易，最开始是需要拉docker镜像的。 稍等一会，就会自动创建容器，并且运行了kafka集群以及zookeeper集群。 可以使用sudo docker ps查看所有运行的容器。

（话外：可以使用lazydocker管理容器，很方便)

下一篇在springboot中集成。
