Docker 之web api 訪問 host sql server
執行 Docker
C:\Users\Administrator>docker run -it -p 5000:5000 --name myapidocker1 webapiv1
[email protected]:/# dir
bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys test tmp usr var
C:\Users\Administrator>docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3b3e97bb6e21 webapiv1 "bash" 9 seconds ago Up 8 seconds 0.0.0.0:5000->5000/tcp myapidocker1
deploy 編譯後的dll,編譯選項選擇如下
D:\Work\My\opensource\Dotnet2\WebAPIForDocker\bin\Debug>docker cp netcoreapp2.1/publish myapidocker1:/test/api3
檢視配置,注意linux 下sqlserver 埠號必須指定
[email protected]:/test/api3/publish# cat appsettings.json
{
"Logging": {
"LogLevel": {
"Default": "Information"
}
},
"AllowedHosts": "*",
"ConnectionStrings": {
"DefaultConnection": "Max Pool Size = 51200;Server=localhost,1433;User ID=sa;Pwd=XXXXX;DataBase=Order;"
}
}
進入到容器
如果不小心關閉了，docker 的終端，再次進入docker
C:\Users\Administrator>docker exec -it myapidocker1 /bin/bash
[email protected]:/# dir
bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys test tmp usr var
執行 core
[email protected]:/test/api3/publish# dotnet WebAPIForDocker.dll

開啟另一個終端，在docker 內部訪問
