通过 Docker-Compose 快速部署 Redis 保姆级教程

# 安装yum-config-manager配置工具
yum -y install yum-utils

# 建议使用阿里云yum源：（推荐）
#yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 安装docker-ce版本
yum install -y docker-ce
# 启动并开机启动
systemctl enable --now docker
docker --version

# 需要查看构建镜像详细过程则需要加上 --progress=plain 选项
docker build -t registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/redis:7.0.3 . --no-cache --progress=plain

# 为了方便小伙伴下载即可使用，我这里将镜像文件推送到阿里云的镜像仓库
docker push registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/redis:7.0.3

### 参数解释
# -t：指定镜像名称
# . ：当前目录Dockerfile
# -f：指定Dockerfile路径
#  --no-cache：不缓存
