Troubleshooting Docker: Fixing the GLIBC_2.34' not found Error

Creating and deploying applications using Docker can be a highly efficient process, but it is not without its challenges. One such challenge that many developers encounter is the infamous error:

/lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.34' not found.

This issue often arises when working with Rust applications in Docker, particularly when using specific versions of Ubuntu as your base image. In this guide, we will explore the cause of this error and provide you with a comprehensive solution to resolving it.

Understanding the Problem

The error you’re seeing typically indicates that the version of the GNU C Library (glibc) required by your Rust application is not available in the base Ubuntu image you are using. This commonly occurs when:

The base image is outdated or lacks the necessary glibc version required for the application.

The build environment (container) does not align with the runtime environment.

The Dockerfile that Generated the Error

Here’s the Dockerfile that leads to the GLIBC_2.34' not found error:

When using this Dockerfile, you may successfully build the image, but running the container will throw the aforementioned error, indicating a missing version of glibc.

The Solution: Change the Ubuntu Version

To fix this issue, an effective solution is to update the base image to a more recent version of Ubuntu that supports the required glibc version. In this case, switching to Ubuntu 21.10 resolves the issue, as it contains the necessary library versions.

Here’s the updated Dockerfile that works seamlessly:

Key Changes Made

Base Image Update: Changed from ubuntu:20.04 to ubuntu:21.10 to provide access to updated libraries.

Copying Source Files: Adjusted the COPY commands to specifically copy necessary source files and configuration, avoiding potential conflicts in the /target directory.

Final Thoughts

Running into library version errors while deploying applications in containers is not uncommon, but with a few adjustments, you can overcome these hurdles successfully. By switching to the appropriate base image, you ensure that your application has access to the necessary libraries, leading to smoother execution and fewer runtime errors.
