🙏废话不多说系列，直接开整🙏
docker 是一个可轻松搬移 redis 的自动方便部署的平台。
（1）查询 docker 中可安装的redis的版本信息
$ docker search redis
结果如下：
drew@ubuntu:/snap/bin$ sudo docker search redis

drew@ubuntu:/snap/bin$
（2）安装最新版的 Redis 镜像
# 如果需要指定版本或者安装最新的，可以如下：
$ docker pull redis:latest
（3）检查本地的镜像
# 检查本地的所有镜像
$ docker images
（4）查看本地镜像中是否存在指定镜像
例如：查看本地是否存在 hello 镜像。
# 查看本地是否存在 hello 镜像。
$ docker images hello
（5）运行容器 ♥
安装完成后，我们可以使用一下命令来运行 redis 容器：
$ docker run -itd --name redis-test -p 6379:6379 redis
参数说明：
【-p 6379:6379】：映射内容服务的 6379端口到宿主机的 6379 端口。外部可以直接通过宿主机 IP:6379 访问到 Redis 服务。
drew@ubuntu:/snap/bin$ sudo docker run -itd --name redis-test-1 -p 6380:6379 redis
99493250795f5ef9156d9eeea9469cb12a15cf54c73bbcc0e38a36f38b19e562
问题①：端口在宿主机上被占用
问题详情
drew@ubuntu:/snap/bin$ sudo docker run -itd --name redis-test -p 6379:6379 redis
4e35d594e2384c7e5cf543663255b9a089969f6423e47b5c63de4db6062bae78
docker: Error response from daemon: driver failed programming external connectivity on endpoint redis-test (b8e098462f013a125f7efa695268d1ff33be0630d44342b2af7f8e0b38915e4e): Error starting userland proxy: listen tcp 0.0.0.0:6379: bind: address already in use.
解决办法
# 修改映射到宿主机的端口，如下
$ docker run -itd --name redis-test-1 -p 6380:6379 redis
# 例如：开启成功后，会返回一个 ID值
drew@ubuntu:/snap/bin$ sudo docker run -itd --name redis-test-1 -p 6380:6379 redis
99493250795f5ef9156d9eeea9469cb12a15cf54c73bbcc0e38a36f38b19e562
（6）安装成功
查看容器的运行信息。
$ docker ps
（7）使用 redis-cli 连接测试 redis 服务
$ docker exec -it redis-test-1 /bin/bash
验证二：使用 外部第三方工具连接redis
（8）退出操作
（9）关闭 docker 中的 redis 服务
① 根据【容器名称】关闭容器服务
$ docker container stop redis-test-1
② 根据【容器ID】关闭容器服务
$ docker container stop "4e35d594e2384c7e5cf543663255b9a089969f6423e47b5c63de4db6062bae78"
# 操作示例：
drew@ubuntu:/snap/bin$ sudo docker run -itd --name redis-test -p 6379:6379 redis
docker: Error response from daemon: Conflict. The container name "/redis-test" is already in use by container "4e35d594e2384c7e5cf543663255b9a089969f6423e47b5c63de4db6062bae78". You have to remove (or rename) that container to be able to reuse that name.
See 'docker run --help'.
drew@ubuntu:/snap/bin$ ^C
drew@ubuntu:/snap/bin$ docker container stop "4e35d594e2384c7e5cf543663255b9a089969f6423e47b5c63de4db6062bae78"

drew@ubuntu:/snap/bin$ sudo docker container stop "4e35d594e2384c7e5cf543663255b9a089969f6423e47b5c63de4db6062bae78"
4e35d594e2384c7e5cf543663255b9a089969f6423e47b5c63de4db6062bae78
（10）查看 Redis 容器的运行日志
$ sudo docker container logs redis-test-1
结果显示
drew@ubuntu:/snap/bin$ sudo docker container logs redis-test-1

（3）♥ Redis从开启到关闭 操作完整流程
# ===========================[计入Redis准备阶段]=====================================
# 从docker中拉取redis版本
$ sudo docker pull redis:latest
# 查看是否拉取redis镜像成功
$ sudo docker images redis
# 运行redis（开启一个新的容器名为redis-test，对外的端口为6380:6379的第一个,使用的镜像名为redis）
# >>> 注意：6380是这个docker 容器对外开放的redis端口，外部网络可以通过 IP:6380 连接到docker中的redis服务的。
$ sudo docker run -itd --name redis-test -p 6380:6379 redis
ab43e282bf0f42de1a8a519b54b83799de094381b6e14f650dfc7970b76ac034
# 检查redis容器运行状态（STATUS的值为UP表示正常）
$ sudo docker ps
# ===========================[进入开启使用阶段]=====================================
# 连接docker中的redis服务
$ sudo docker exec -it redis-test /bin/bash
# 进入docker容器redis-test 客户端CMD
$ redis-cli
# 进入使用redis 阶段
127.0.0.1:6379 > set test 1
OK
127.0.0.1:6379 > keys *
1) "test"
# ===========================[进入退出关闭阶段]=====================================
# 退出redis 服务
127.0.0.1:6379> exit
root@2dea66f68822:/data# exit
exit
# 关闭redis容器
$ sudo docker container stop redis-test
