when i ran the https commands above it says my cert is valid so why?

AresOP•2/29/24, 9:13 PM

i tried

EXPOSE 443
EXPOSE 8081

EXPOSE 443
EXPOSE 8081

EXPOSE 443
EXPOSE 8081

EXPOSE 443
EXPOSE 8081

too

Pobiega•2/29/24, 9:21 PM

docker + dev cert = bad idea

P

Pobiega•2/29/24, 9:21 PM

the dev cert is only for local development, once you are ready to host the API you're looking at providing a real https cert, probably via a reverse proxy

AresOP•2/29/24, 9:29 PM

i dont really understand cause now i am trying to run with IIS express i think that something is wrong. but i didnt do anything out of the ordinary im going to restart my computer and see if that helps

A

AresOP•2/29/24, 9:35 PM

yeah i dont really understand why its doing this, it builds and runs the image just fine but then after that i see all of this in the console. nothing i tried helped at all

i went to properties/launchoptions and made useSSL false too so im not sure why

nvm resolved

AresOP•3/1/24, 3:51 AM

https://learn.microsoft.com/en-us/aspnet/core/security/docker-compose-https?view=aspnetcore-8.0 i did this and changed to 8080 and 8081 instead of 5000 and 5001

T

TeBeCo•3/1/24, 5:48 AM

docker is not DEV

T

TeBeCo•3/1/24, 5:48 AM

so you can / shouldn't use the devcert certificate for docker @Ares

T

TeBeCo•3/1/24, 5:48 AM

because that dev cert is

localhost

localhost

T

TeBeCo•3/1/24, 5:48 AM

which means that once in Docker ... localhost is the docker only

T

TeBeCo•3/1/24, 5:49 AM

so anything trying ot reach the container is not localhost anymore

T

TeBeCo•3/1/24, 5:49 AM

so even if you'd managed to generate it / copy it / install it / bind it

T

TeBeCo•3/1/24, 5:49 AM

you'll leak security warning to anything connectign to it

AAres i dont really understand cause now i am trying to run with IIS express i think t...

T

TeBeCo•3/1/24, 5:50 AM

note: IIS Express is a windows thing no one should ever use, unless you're debbugging a bug related to IIS on prod, if you're seeing IIS Express, you're using the wrong profile

AAres ``` "Docker": { "commandName": "Docker", "launchBrowser": true, ...

T

TeBeCo•3/1/24, 5:51 AM

the ENV VAR changed for net8, just make sure to match them properly, also note that this will only be for these profiles, and also internal of the container

T

TeBeCo•3/1/24, 5:51 AM

ie: unrelated to your

-p

-p

-p

-p

T

TeBeCo•3/1/24, 5:51 AM

you will also need to make that match

T

TeBeCo•3/1/24, 5:51 AM

T

TeBeCo•3/1/24, 5:52 AM

this is what's written there

T

TeBeCo•3/1/24, 5:54 AM

===========

never use IIS / IIS Express unless company force you
never use dev-cert inside a container
update env var to match new aspnetcore 8 ones (because MSFT did a breaking change)
launchSettings only works for
```
F5
```
F5
```
F5
```
F5
and won't be used at anytime outside of VS
make sure your
```
-p
```
-p
```
-p
```
-p
matches both side
make sure your https redirect match the
```
-p
```
-p
```
-p

from the HOST and not from the container
