MVC project uses Web API project inside same Docker container
Question
I am trying to learn more about Docker in my free time. I am currently trying to get ASP.NET Identity Server to work with it.
Here are the steps I have taken:
Download: https://github.com/IdentityServer/IdentityServer4.Samples/tree/release/Quickstarts/6_AspNetIdentity
Run the ASP.NET MVC client application and the server application and browse to the following URL to make sure it is working properly: http://localhost:5002/Home/CallApiUsingClientCredentials
The code looks like this:
public async Task<IActionResult> CallApiUsingClientCredentials() { var tokenClient = new TokenClient("http://localhost:5000/connect/token", "mvc", "secret"); var tokenResponse = await tokenClient.RequestClientCredentialsAsync("api1"); var client = new HttpClient(); client.SetBearerToken(tokenResponse.AccessToken); var content = await client.GetStringAsync("http://localhost:5001/identity"); ViewBag.Json = JArray.Parse(content).ToString(); return View("Json"); }I get the response I am expecting.
Right click on the API project and select Add Container Orchestration Support.
- Right click on MVCClient and select: Add/Container Orchestration Support.
Docker Compose Override then looks like this:
version: '3.4'
services:
mvcclient:
environment:
- ASPNETCORE_ENVIRONMENT=Development
ports:
- "5002:80"
api:
environment:
- ASPNETCORE_ENVIRONMENT=Development
ports:
- "5001:80"
identityserverwithaspnetidentity:
environment:
- ASPNETCORE_ENVIRONMENT=Development
ports:
- "5000:80"
Make changes to the code above as follows:
Line 3 change to:
var tokenClient = new TokenClient("http://identityserverwithaspnetidentity:80/connect/token", "mvc", "secret");
Line 10 change to:
var content = await client.GetStringAsync("http://api:80/Identity");
When I browse to http://localhost:5002/Home/CallApiUsingClientCredentials ; I am receiving a weird response:
<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"><html><head><meta http-equiv=\"refresh\" content=\"0;url=http://www.webaddresshelp.bt.com/main?ParticipantID=mg76cjr54t8kx45jjw4j4k9j5hsr5m26&FailedURI=http%3A%2F%2Fapi1%2FIdentity&FailureMode=1&Implementation=&AddInType=4&Version=pywr1.0&ClientLocation=uk\"/><script type=\"text/javascript\">url=\"http://www.webaddresshelp.bt.com/main?ParticipantID=mg76cjr54t8kx45jjw4j4k9j5hsr5m26&FailedURI=http%3A%2F%2Fapi1%2FIdentity&FailureMode=1&Implementation=&AddInType=4&Version=pywr1.0&ClientLocation=uk\";if(top.location!=location){var w=window,d=document,e=d.documentElement,b=d.body,x=w.innerWidth||e.clientWidth||b.clientWidth,y=w.innerHeight||e.clientHeight||b.clientHeight;url+=\"&w=\"+x+\"&h=\"+y;}window.location.replace(url);</script></head><body></body></html>
What is the problem please?
Update
Why do the lines below return the output above (what I referred to as the weird response):
var content = await client.GetStringAsync("http://bert:80/Identity");
var content = await client.GetStringAsync("http://somerandomserver:80/Identity");
var content = await client.GetStringAsync("http://hello:80/Identity");
bert; somerandomserver and hello do not exist. It appears the response above is always received as long as I use port 80 ie regardless of the server name I use ie I can make it up. Why?

For web apps in docker compose , they are sharing the same networks in the Compose .
Per to your steps, it seems you only changed the request URLs. You also need to change the Authority in api project.
Try to change src\\Api\\Startup.cs with below:
services.AddAuthentication("Bearer")
.AddIdentityServerAuthentication(options =>
{
options.Authority = "http://identityserverwithaspnetidentity:80";
options.RequireHttpsMetadata = false;
options.ApiName = "api1";
});
