一文教你如何构建 Redis Docker镜像

简介

由于版本的需求，需要编译使用新版本的redis。

准备基础镜像

dockerimporthttps://mirrors.aliyun.com/alpine/v3.15/releases/x86_64/alpine-minirootfs-3.15.0-x86_64.tar.gzalpine:3.15.0

启动文件

#!/bin/sh
set-e

port=6379
if["$PORT"!=""];then
port=$PORT
fi
data_dir=/data/redis/data
if["$DATADIR"!=""];then
data_dir=$DATADIR
fi
mkdir-p$data_dir
password=""
if["$PASSWORD"!=""];then
password=$PASSWORD
fi
maxmemory=0
if["$MAXMEMORY"!=""];then
maxmemory=$MAXMEMORY
fi
protected_mode="no"
if["$PROTECTEDMODE"!=""];then
protected_mode=$PROTECTEDMODE
fi
if[["$PASSWORD"==""&&"$protected_mode"=="yes"]];then
echo"protected-modeneedpassword!!!!"
exit1
fi

Dockerfile

#!/bin/bash

cat>Dockerfile<<EOF

使用

dockerrun-itd-ePASSWORD=123-ePORT=7000-eMAXMEMORY=5gb-ePROMTECTEDMODE=yes-eDATADIR=/data/redisredis:v6.2.6

支持变量：

• PASSWORD：密码
• PORT：端口
• MAXMEMORY:最大内存
• PROMTECTEDMODE：保护模式(默认是：no)
• DATADIR:数据目录
