首先linux機上安裝了docker後需要再安裝docker compose，安裝比較簡單，直接拷貝官網教程
For alpine, the following dependency packages are needed: py-pip, python-dev, libffi-dev, openssl-dev, gcc, libc-dev, and make.
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
Note: If the command docker-compose fails after installation, check your path. You can also create a symbolic link to /usr/bin or any other directory in your path.
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
Test the installation:
docker-compose --version
首先創建一個目錄用來放配置文件：/usr/local/redis-compose
新建一個redis.conf配置文件，這裏端口使用16379
daemonize no
bind 0.0.0.0
appendonly no
port 16379
創建docker-compose.yml文件
version: '3.5'
services:
redis:
image: "redis:latest"
container_name: my_redis
command: redis-server /etc/redis/redis.conf
ports:
- "16379:16379"
volumes:
- ./data:/data
- ./redis.conf:/etc/redis/redis.conf
參數說明：
version：docker-compose版本，這裏使用3.5版本
services：一個service就是一個容器實例
image：表示使用哪個鏡像，兒裏使用遠程image
container_name：設定實例名，不指定的話會根據當前路徑和文件配置生成一個名字，如這裏不指定名稱，會是"redis_compose_redis_1"
command：指定運行的命令，這裏會使用本地文件redis.conf掛載到容器的/etc/redis/路徑下然後用該文件啓動
volumes：這裏掛載/data路徑和redis.conf文件
啓動容器：
docker-compose up
控制檯輸出：

啓動成功
也可以後臺運行
docker-compose up -d
使用docker-compose logs -f查看日誌
使用docker ps命令可以看到該實例
通過redis-cli工具連接該實例：
