"Error loading shared library ld-linux-x86-64.so.2" on Alpine

[mflis]

Describe the bug

Running aws-sdk-kotlin on Alpine linux results in following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/AWSCRT_164078280020313186175181261409494libaws-crt-jni.so: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /tmp/AWSCRT_164078280020313186175181261409494libaws-crt-jni.so)

Java AWS SDK (""software.amazon.awssdk:aws-sdk-java") works fine on Alpine Linux.
As a workaround I changed my base docker image from Alpine to CentOS

Expected behavior

aws-sdk-kotlin works fine on Alpine Linux

Current behavior

Trying to create S3Client results in following stacktrace:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/AWSCRT_164078473572713457532869063683722libaws-crt-jni.so: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /tmp/AWSCRT_164078473572713457532869063683722libaws-crt-jni.so)

Steps to Reproduce

git clone https://github.com/mflis/aws-kotlin-alpine-error.git
./gradlew jibDockerBuild
docker run aws-alpine-error

Possible Solution

No response

Context

We use alpine linux as a standard base container in our company to achieve small docker images.

AWS Kotlin SDK version used

aws.sdk.kotlin:s3:0.9.5-beta

Platform (JVM/JS/Native)

JVM

Operating System and version

Alpine Linux v3.14

Hi @mflis , thanks for providing the issue and easy repro steps. At this time an internal dependency of the AWS SDK for Kotlin (CRT) does not support Alpine Linux.

Unlike the Java v2 SDK, at this time it is not possible to use the Kotlin SDK without CRT, so this is blocking the usage of applications using the Kotlin SDK on Alpine and other musl-based distributions.

[ianbotsf]

This should be fixed in 0.16.1-beta since the SDK no longer uses the CRT by default.

NOTE: Multi Region Access Points (which the SDK does not yet support, see #625) still may require explicitly configuring a CRT based signer, we are still investigating paths forward.

Hi, any updates on this? I am trying out awssdk 2.20.102 and awssdk.crt 0.22.5 and it still fails.
is there a workaround this issue?

[ianbotsf]

Hi @carmithersh, 2.20.102 is the latest version of the AWS SDK for Java whereas this issue was for the AWS SDK for Kotlin. You can follow the issue for supporting CRT on Alpine Linux for AWS SDK for Java at aws-sdk-java-v2#2868.
