Docker 安装 Redis

java

http://www.runoob.com/docker/docker-install-redis.html
通过 Dockerfile 构建

创建Dockerfile

首先，创建目录redis,用于存放后面的相关东西。

1. runoob@runoob:~$ mkdir -p ~/redis ~/redis/data

复制代码

data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录

进入创建的redis目录，创建Dockerfile

1. FROM debian:jessie
   
2. 
   
3. # add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added

通过Dockerfile创建一个镜像，替换成你自己的名字

1. runoob@runoob:~/redis$ docker build  -t redis:3.2 .

复制代码

创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像

1. runoob@runoob:~/redis$ docker images redis
   
2. REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
   
3. redis               3.2                 43c923d57784        2 weeks ago         193.9 MB

复制代码

使用redis镜像运行容器

1. runoob@runoob:~/redis$ docker run --name redis  -p 6379:6379 -v $PWD/data:/data  -d redis:3.2 redis-server --appendonly yes

复制代码

命令说明：

-p 6379:6379 :将容器的6379端口映射到主机的6379端口

-v $PWD/data:/data :将主机中当前目录下的data挂载到容器的/data

redis-server --appendonly yes :在容器执行redis-server启动命令，并打开redis持久化配置

出现如下错误：

docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"docker-entrypoint.sh\": executable file not found in $PATH".

在COPY后加上下面一句话：

1. RUN chmod +x /usr/local/bin/docker-entrypoint.sh

复制代码

验证：

进入docker容器

docker exec -it redis bash

登录本机redis

~ redis-cli
redis 127.0.0.1:6379>

设置 一个键值

127.0.0.1:6379> set key1 "tutut"

OK

127.0.0.1:6379> get key1

"tutut"

远程连接 测试
redis-cli -h 192.168.134.106 -p 6379

192.168.134.106:6379> get key1
"tutut"

exit退出
测试 连接 成功！

连接、查看容器

使用redis镜像执行redis-cli命令连接到刚启动的容器,主机IP为172.17.0.1

1. runoob@runoob:~/redis$ docker run -it redis:3.2 redis-cli -h 172.17.0.1
   
2. 172.17.0.1:6379> info

5. redis_git_sha1:00000000
   
6. redis_git_dirty:0
