Failed to initialize CoreCLR, HRESULT: 0x80004005

[bdaniel7]

Hi,

I'm trying to run a TeamCity agent in a container.
This is environment:

The TeamCity and the agent are the latest from the container (2018.1.3 (build 58658))
The container is run in Docker for Windows, using Linux containers (because the production will run on Ubuntu).

root@teamcity-agent3:/opt/buildagent/work/70bf5e8b1cc61bbe/src# dotnet --info
.NET Core SDK (reflecting any global.json):
Version: 2.1.401
Commit: 91b1c13032

Runtime Environment:
OS Name: ubuntu
OS Version: 16.04
OS Platform: Linux
RID: ubuntu.16.04-x64
Base Path: /usr/share/dotnet/sdk/2.1.401/

Host (useful for support):
Version: 2.1.3
Commit: 124038c13e

.NET Core SDKs installed:
2.1.401 [/usr/share/dotnet/sdk]

.NET Core runtimes installed:
Microsoft.AspNetCore.All 2.1.3 [/usr/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.3 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.1.3 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET Core runtimes or SDKs:
https://aka.ms/dotnet-download

When I run the build using

/opt/buildagent/work/70bf5e8b1cc61bbe/src# /usr/bin/dotnet build trains.sln --framework netcoreapp2.1 --configuration Release --runtime ubuntu-x64

in the container, the build is successful.

However when I run the same command as part of a build step, I get this error:

Failed to initialize CoreCLR, HRESULT: 0x80004005

Any ideas on why this error occurs?

[bdaniel7]

I think this occurs because the teamcity agent runs under buildagent user and the folders and files created during agent instalation (/opt, /tmp) are rw only for root:root.

I tried to add root to group docker and set chown those directories to root:docker but to no avail. New folders generated when the any "dotnet" command starts are owned and rw by root.

I have the same issue. Any ideas?

[bdaniel7]

One workaround is to set the environment variable COMPlus_EnableDiagnostics=0 in all the containers where dotnet runs.
The variable is used to determine whether the clr will write some debug information in /tmp.
You can search for more details about that variable in the .NET Core GitHub issues log.

@bdaniel7 Thank you. It`s helped

@bdaniel7 could you share commands which are used to run TeamCity server and agent in docker?

[bdaniel7]

They are run using docker-compose:
teamcity-server:
restart: always
image: jetbrains/teamcity-server:latest
container_name: teamcity
hostname: 'teamcity'
depends_on:
- "db"
environment:
- COMPlus_EnableDiagnostics=0
ports:
- 8111:8111
volumes:
- /docker/teamcity/data:/data/teamcity_server/datadir
- /docker/teamcity/logs:/opt/teamcity/logs
labels:
- 'traefik.frontend.rule=Host:teamcity.my.domain'
- 'traefik.backend=teamcity-backend'
- 'traefik.domain=my.domain'
- 'traefik.port=8111'
networks:
- trains-backend

teamcity-agent1:
restart: always
image: bdaniel7/teamcity-docker-agent-with-node:latest
container_name: teamcity-agent1
hostname: 'teamcity-agent1'
environment:
- 'SERVER_URL=http://teamcity:8111'
- 'AGENT_NAME=zozo'
- 'TMPDIR=/tmp'
- COMPlus_EnableDiagnostics=0
volumes:
- /var/run/docker.sock:/var/run/docker.sock

- '/docker/teamcity_agent1/tools:/opt/buildagent/tools'
- '/docker/teamcity_agent1/plugins:/opt/buildagent/plugins'

@bdaniel7 by default TeamCity agent uses this TEMP directory TMPDIR=/opt/buildagent/temp/buildTmp. Try using the same.
