Cannot build - Githubissues

janaxhell commented 10 months ago

I'm trying to deploy this on docker x86, I've cloned the git, but when I try to build, the operation fails:

What can I check?

HolyMolyCowMan commented 10 months ago

I had the same issue. I can't confirm everything works as of right now, but it will build.

To fix: In 'Dockerfile' change FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build to FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build

and

FROM mcr.microsoft.com/dotnet/aspnet:7.0 to FROM mcr.microsoft.com/dotnet/aspnet:8.0.

DavidLazarescu commented 10 months ago

Right, thanks for pointing that out. I have updated the server to .NET 8 some days ago, but forgot to update that in the docker files.

janaxhell commented 10 months ago

Thank you, I was able to build with that fix, now off to compose!

This is my compose, omv1 is a network I've created that already works fine with other containers:

Also, what is JWT key in the compose? Should I use it? Comment it? What is it for?

According to the error, it failed when connecting to the database:

An error occurred using the connection to database '' on server 'mariadb'.

Apparently, it's not picking it up from the environment variable. Has it been changed in any way?

janaxhell commented 10 months ago

No, all you see is all I did: build image, adapt compose with what you see, deploy stack from Portainer. No ENV touched by me.

tralph3 commented 10 months ago

I'm asking about the project in general. Seeing as it has been updated to use a newer version of .NET without updating the Dockerfile, maybe the DBString was updated as well, causing the error.

I don't think anything changed there.

I had the same issue, running the example docker-compose.yml

tenekev commented 10 months ago

Same issue. Appeared after updating to the latest version. I tried toying with the env variables, different formatting and such but nothing solved it.

I checked the DB itself and it appears to be populated correctly. However, I cannot go any further in order to determine if the error message causes actual problems because of issue #20 .

I sadly don't have a lot of experience with docker. @tralph3 @tbabej @3036662 might know more here since they have setup the docker stuff

tenekev commented 10 months ago

I think this issue should be closed as the original one was resolved. The following database connection issue should be a separate issue anyway.

That being said, I don't think it's an actual issue. A fresh setup continues to give this error and I think it's a simple timing issue. The librum-server container initializes before the db container and shoots the error. Once the db container is up, librum-server continues as normal. I think a simple heartbeat on the db container should fix the problem.

I took a look at it after 10 months of not using it at all and the problem is still there. I have updated to the latest image, tried to stop and start the app after the db was running, but all I see is a repeating error:
