docker 暗转redis

Posted 2021-12-28 memoryxudy

方法一、docker pull redis:3.2

查找Docker Hub上的redis镜像

[email protected]:~/redis$ docker search  redis

这里我们拉取官方的镜像,标签为3.2

[email protected]:~/redis$ docker pull  redis:3.2

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为redis,标签为3.2的镜像。

[email protected]:~/redis$ docker images redis 
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
redis               3.2                 43c923d57784        2 weeks ago         193.9 MB

使用redis镜像

运行容器

[email protected]:~/redis$  docker run -p 6679:6379 --name redis  -v $PWD/data:/data  -d redis:5.0 redis-server --appendonly yes --requirepass "789"
43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330
[email protected]:~/redis$

命令说明：

-p 6679:6379 : 将容器的6379端口映射到主机的6679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

--requirepass "789" 设置密码

查看容器启动情况

[email protected]:~/redis$ docker ps
CONTAINER ID   IMAGE        COMMAND                 ...   PORTS                      NAMES
43f7a65ec7f8   redis:3.2    "docker-entrypoint.sh"  ...   0.0.0.0:6379->6379/tcp     agitated_cray

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

[email protected]:~/redis$ docker exec -it 43f7a65ec7f8 redis-cli
