pipelines agent on alpine reporting error relocating ./bin/libcoreclr.so

[ArthwitRail]

Agent Version and Platform

2.166.3 - Alpine Linux 3.11.5 (x86-64)

What's not working?

trying to get Alpine to run the azure pipelines agent 2.166.3, i have installed and configured many agents before on RH7 and Windows without issues.

I have downloaded the agent and tried running config.sh but it is outputting

fubar:~/myagent$ ./config.sh Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by ./bin/libcoreclr.so) Error relocating ./bin/libcoreclr.so: __finite: symbol not found Error relocating ./bin/libcoreclr.so: __isnan: symbol not found Error relocating ./bin/libcoreclr.so: __finitef: symbol not found Error relocating ./bin/libcoreclr.so: __isnanf: symbol not found Error relocating ./bin/libcoreclr.so: pthread_attr_setaffinity_np: symbol not found Error relocating ./bin/System.Net.Http.Native.so: __strdup: symbol not found libicu's dependencies missing for .NET Core 3.1 Execute ./bin/installdependencies.sh to install any missing dependencies. fubar:~/myagent$

appreciate that alpine is a musl based distro and i believe i have satisfied all the dependencies listed when the dotnet-install.sh script runs and outputs the missing dependency warnings.

the musl lib and gcc are working fine as i have ported my application to Alpine i just need to add it into my build pipe as a target but cat get the agent running to do that.

first question is should i be able to run the agent on alpine ?

more info on config below - happy to supply anything else required.

Do you have the Dockerfile available, so I can debug it ?

[ArthwitRail]

No docker involved - this is a real alpine vm running in VSphere, i thought i had loaded all the pre-req but i cant seem to get the agent to start. TBH i havent tried it for a while as i worked round it by putting an agent on an RH7 linux VM azure and scp'ing the checkout made by the agent to the remote Alpine system and running my build using ssh, then pulling back the artifacts for publishing into the rest of my build pipe.

I would rather run the agent on Alpine.

Same problem with Alpine 3.13.
I am trying to create a way to build Azure Pipeline agent on Azure based on Alpine using packer
I tried to install all the dependency following the docs, included the .NET ones:

# SW Pre-reqs 
apk add openssl sudo shadow parted e2fsprogs iptables sfdisk
apk add python3 py3-setuptools
apk add curl unzip e2fsprogs-extra
apk add icu-libs krb5-libs libgcc libint libstdc++ zlib gcompat
apk add libintl libssl1.1
# .NET Requirements
apk add bash icu-libs krb5-libs libgcc libintl libssl1.1 libstdc++ zlib
apk add libgdiplus --repository https://dl-3.alpinelinux.org/alpine/edge/testing/

When I try to run ./config.sh --help I get:

Any update here?

[SymbioticKilla]

Is there any ETA? Thanks!

[anatolybolshakov]

Hi @SymbioticKilla is it still reproducible for you with latest agent version?

[SymbioticKilla]

Hi @anatolybolshakov,

sorry, was just curios if it is on the road map. I'm waiting for official support. Due to compliance rules in our company unfortunately I can't test unofficial stuff.

[EzzhevNikita]

@SymbioticKilla Support of Alpine will require a separate build of our Agent (linux-musl-x64). As I know we don't have plans for official support of Alpine, so the support of this OS won't appear in the nearest future.

[dkadetov]

I was trying to use alpine-glibc image. But I had the same issue.

[Socolin]

I have the same issue

[github-actions]

This issue has had no activity in 180 days. Please comment if it is not actually stale

[SymbioticKilla]

No Plan to support alpine?

[towerbe]

Can we reopen this issue? There is full support for .NET Core - at least 3.1 - for Alpine now. Not being able to use Alpine for containerized agents forces us to have huge, bloated containers due to use of other less streamlined OS images.

Related story is #1319

Hi everyone,

Any news about this topic?

I really need it to run official docker:dind images as build agents in Azure Pipelines. Especially when .NET 6 is officially supported on Alpine.
