TeamCity run step in docker

[jonetta]

I'm trying to set up TeamCity to run tests on a .NET project. I have installed TeamCity and its agent (with access to docker) using docker compose :

  teamcity:
    image: jetbrains/teamcity-server
    container_name: teamcity
    volumes:
     - /home/arsene/teamcity/data:/data/teamcity_server/datadir
     - /home/arsene/teamcity/logs:/opt/teamcity/logs
    environment:
      - TEAMCITY_HTTPS_PROXY_ENABLED=true
    labels:
      - traefik.http.routers.teamcity.rule=Host(`myhost`)
      - traefik.http.routers.teamcity.tls=true
      - traefik.http.routers.teamcity.tls.certresolver=le   
      - traefik.http.services.teamcity.loadbalancer.server.port=8111
teamcityagent:

image: jetbrains/teamcity-agent

container_name: teamcityagent

volumes:

- /home/arsene/teamcity/agent:/data/teamcity_agent/conf

- /var/run/docker.sock:/var/run/docker.sock

- /opt/buildagent/work:/opt/buildagent/work

- /opt/buildagent/temp:/opt/buildagent/temp

environment:

- AGENT_NAME=TeamCityRunner

- SERVER_URL=myhost

- DOCKER_IN_DOCKER=start

privileged: true

When I configure my project I select the following config :

But my build fail with very few detail about whats wrong.

Step 1/2: Test (.NET)
  Running step within Docker container mcr.microsoft.com/dotnet/sdk:5.0
  dotnet test
    Starting: .NET SDK 5.0.408 /usr/bin/dotnet test /opt/buildagent/work/e83eb8da5bf3868c/ImPresent.Tests/ImPresent.Tests.csproj @/opt/buildagent/temp/agentTmp/1.rsp
    in directory: /opt/buildagent/work/e83eb8da5bf3868c
    MSBUILD : error MSB1021: Cannot create an instance of the logger. The given assembly name or codebase was invalid. (0x80131047)
    Switch: TeamCity.MSBuild.Logger.TeamCityMSBuildLogger,/opt/buildagent/plugins/dotnet/tools/msbuild15/TeamCity.MSBuild.Logger.dll;TeamCity;plain
    Process exited with code 1
    Process exited with code 1 (Step: Test (.NET))
  Step Test (.NET) failed

Do you have any idea of what could be wrong, or how to check logs the have more details ? I ran my tests in the same container on my desktop, they pass.

Two things I would try:

1. Add "Build" Step before testing:

   Runner Type: .NET.

   Command: build.

   Also it may be required to add another build configuration to Restore the project before build.

2. Execute this build step in "verbose" mode to get more logging information.
