Docker 之web api 访问 host sql server

运行 Docker

C:\Users\Administrator>docker run -it  -p 5000:5000 --name myapidocker1 webapiv1

root@3b3e97bb6e21:/# 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 编译后的dll,编译选项选择如下

D:\Work\My\opensource\Dotnet2\WebAPIForDocker\bin\Debug>docker cp netcoreapp2.1/publish myapidocker1:/test/api3

查看配置,注意linux 下sqlserver 端口号必须指定

root@3b3e97bb6e21:/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;"

}

}

进入到容器

如果不小心关闭了，docker 的终端，再次进入docker

C:\Users\Administrator>docker exec -it myapidocker1 /bin/bash

root@3b3e97bb6e21:/# dir

bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  test  tmp  usr  var

运行 core

root@3b3e97bb6e21:/test/api3/publish# dotnet WebAPIForDocker.dll

打开另一个终端，在docker 内部访问

webAPI部分代码：

 

[Route("api/[controller]")]

public class OrdersController : Controller

{

private IConfigOptions m_configOptions;

private ILogger m_logger;
