redis image
免錢管理工具AnotherRedisDesktopManager
最好裝一下剛剛的管理工具 , 才可以快速驗證後續的 lab 內容

#下載 redis image
docker search redis
docker pull redis

#執行 redis 並且保存資料
cd $home
mkdir redis_data

#啟動 redis
docker run --name redis -p 6379:6379 `
-v $home/redis_data:/data -d redis

進入到 container redis bash , 並且用 redis-cli 進行連線
注意這邊是用 string , 跟稍後在程式內使用 hash 不同 , 測試 abp 寫入是會用 string , 沒研究那麼深

docker exec -it 435 /bin/bash
redis-cli
set test helloworld

直接在 host 使用 telnet 對 redis 進行連線
win + r => control => 程式和功能 => 開啟或關閉 windows 功能 => Telnet Client

telnet 127.0.0.1 6379
get test

#匯入模組
Install-Module -Name Posh-SSH

#輸入 linux 登入帳號密碼
$credential = Get-Credential

#注意要用系統管理員 , 並且在 $home 底下先新增資料夾 redis_data
#10.1.25.123 => 你的遠端 linux 機器 ip
gsudo Set-SCPFile -ComputerName '10.1.25.123' -Credential $credential  `
-RemotePath "/home/yourname/redis_data/" -LocalFile 'C:\Users\YourName\redis_data\dump.rdb'

開第二台 redis , 拿其它 linux 機器上的 redis 測試 (注意本次是在遠端 linux 上執行)

#看看是否執行成功
docker container ls

加入 docker support , 預設的 docker file 如下

=> ERROR [build 3/7] COPY [DockerRedisLab/DockerRedisLab.csproj, DockerRedisLab/]

其實只要往上切一層就可以正常運作了

1
docker build --no-cache -t lab -f .\DockerRedisLab\Dockerfile .

其實可以偷偷加上 redis 在裡面

docker exec -it f28 /bin/bash
apt update
apt install

自己加 curl 在我們的 lab container 裡面
