Excluding Health Checks from Serilog Request Logging

Great blog post by Andrew Lock on this very topic: https://andrewlock.net/using-serilog-aspnetcore-in-asp-net-core-3-excluding-health-check-endpoints-from-serilog-request-logging/

docker-fundamentals's Issues

Issue after clicking the Signin link

When I click on the Sign-In link then it will redirect to an error page and show the below error-

Sorry, there was an error: invalid_request
Invalid redirect_uri

RedirectUris "https://www-local.globomantics.com:44395/signin-oidc"

I updated the above redirecturis to localhost URI also but still sign-in is not working.

Please help.

Solution not working

Hi

Swagger is not working please post your appsettings.json and startup.cs for all 3 projects.

PersistedGrantDbContext database migration problem

I got course Fundamentals of Docker and Kubernetes for .NET Developers at pluralsight.I am trying to run project but get an error on migration. The error message in each try mentioned below.
{"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"}

dbConnection => Server=globosql;Database=GlobomanticsIdSrv;User Id=sa;Password=Sqlc0ntainersFTW!;MultipleActiveResultSets=true

In last try i got StackOferflowException. I attach an error also. Need your help :)

bin/bash does not exist

Hi Erik

This has been a really great course for me. I'll probably end up watching it several more times. I am, however, having one problem that I lack enough experience in Linux to solve. I'm getting this error when trying to run the sql stuff

/usr/bin/env: 'bash\r': No such file or directory

This is during this command in the sql.Dockerfile

CMD ["/bin/bash", "entrypoint.sh"]

I'm sure this is something easy but I'm stumped. Can you help? I do see that in actual fact that folder and file (bin & bash) do exist. But docker thinks not I guess.

Solution doesn't work

Hi, coming from pluralsight.

When launching the multiple projects:

• API page doesn't load the swagger documentation page, even by adding /index.html (HTTP ERROR 404).
• The identity server page doesn't load (keeps loading...).
• The website starts, but clicking on any link (including sign-in) redirects to an error page (HTTP ERROR 500).

As you suggest in the other issue, nothing is logged on the console or on the output window.

seq log empty in kubernetes

Hi Erik, thanks for the great course, one of the bests on pluralsight in my view.
I try to follow it carefully to develop my own project and there is still one problem I cannot solve.
Seq log works perfect in docker env. but in kubernetes is empty all the time. I spent much time trying to solve it but no success. Have you got any clue what could be a possible reason for this? Or how I could invastigat it?

Nginx Issue

Hi Erik, thanks for the great course, one of the bests on Pluralsight in my view.

Separate branch for pre docker implemetation

Hi,

I am referring pluralsight course. After cloning main branch, getting errors because this is final version of code with docker implementation.
Would be helpful if you could provide section-wise branch. I am referring section 2 and not able to fix issues.

Thanks in advance
