docker 安装kafka
`https://hub.docker.com/search?q=kafka`!(data/attachment/forum/202304/07/102035palf983rdbezzgfg.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
## Get this image
The recommended way to get the Bitnami Apache Kafka Docker Image is to pull the prebuilt image from the (https://hub.docker.com/r/bitnami/kafka).
```console
docker pull bitnami/kafka:latest
```
To use a specific version, you can pull a versioned tag. You can view the (https://hub.docker.com/r/bitnami/kafka/tags/) in the Docker Hub Registry.
```console
docker pull bitnami/kafka:
```
If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.
```console
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .
```
## 安装docker以及docker compose
推荐使用docker compose进行安装
如果没有安装过，可以先安装docker
```
#升级yum
sudo yum update
#卸载旧版本docker
sudo yum remove dockerdocker-common docker-selinux docker-engine
#安装依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
#设置源
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum makecache fast
#安装docker
sudo yum install docker-ce
#启动服务
sudo systemctl start docker
#查看版本
docker version
#拉取镜像
docker pull hello-world
#启动容器
docker run hello-world
```
然后安装docker compose
```
sudo curl -L https://github.com/docker/compose/releases/download/2.17.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
```
注意:
如果网络不行，可以先下载，我是win10上面的centos虚拟机，下载的是docker-compose-linux-x86_64，然后上传上去，放到某个位置后，修改下名字，比如上面的路径就可以
查看版本号确认情况
```
docker-compose -v
```
## dockerfile文件
官网有说明:
`https://hub.docker.com/r/bitnami/kafka`
!(data/attachment/forum/202304/07/173419s87yt03vtqzp0l82.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
分别介绍了使用zk以及不用zk的方式
上面的文件中最左边的+ - 号是对比标识，-号的删除，+号的保留，没有符号的也保留，然后最后去掉这个最左边的+ - 号。
最终文件如下:
```
version: "3"
services:
kafka:
image: 'bitnami/kafka:latest'
ports:
- '9092:9092'
environment:
- KAFKA_ENABLE_KRAFT=yes
- KAFKA_CFG_PROCESS_ROLES=broker,controller
- KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
- KAFKA_CFG_LISTENERS=PLAINTEXT://:9092
- KAFKA_CFG_LISTENERS=PLAINTEXT://:9092,CONTROLLER://:9093
- KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT
- KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://127.0.0.1:9092
- KAFKA_BROKER_ID=1
- KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=1@127.0.0.1:9093
- ALLOW_PLAINTEXT_LISTENER=yes
```
我只是本地测试用，其他参数就不配置了，就这样
保存为docker-compose.yml
## 安装启动kafka
在这个路径下执行:
`docker-compose up -d`

可以看到正常安装
