This comprehensive guide will walk you through the process of fixing the
standard_init_linux.go:178 error, which is also known as the "Exec Format Error" in the Exec User Process. This error usually occurs when the Docker container is not able to execute a binary file due to an incompatible architecture or a corrupted file. By following the steps in this guide, you'll be able to identify the root cause of the problem and apply the appropriate solution.

Understanding the Exec Format Error
The "Exec Format Error" occurs when the Docker container is unable to execute a binary file. This error is represented by the
standard_init_linux.go:178 error message, which indicates that there's an issue with the Exec User Process. The error message might look like this:
standard_init_linux.go:178: exec user process caused "exec format error"
This error can occur for various reasons, such as an incompatible architecture between the host and the container, a corrupted binary file, or incorrect file permissions.
Possible Causes of the Error
Incompatible architecture: The binary file was compiled for a different architecture than the one used by the Docker container. For example, the binary file is compiled for an ARM-based system, but the Docker container is running on an x86-based system.
Corrupted binary file: The binary file might be corrupted or damaged, making it impossible for the Docker container to execute it.
Incorrect file permissions: The binary file might not have the correct file permissions, preventing the Docker container from executing it.
Check the architecture of the binary file: To determine the architecture of the binary file, you can use the
file command. Run the following command in your terminal:
This command will display the architecture of the binary file. If the architecture is different from the one used by the Docker container, you'll need to recompile the binary file for the correct architecture or use a container that supports the binary file's architecture.
Verify the integrity of the binary file: If the binary file has been corrupted or damaged, you can use a checksum tool like
sha256sum to verify its integrity. Compare the checksum of the binary file with the original checksum to ensure that they match. If they don't match, you'll need to obtain a new copy of the binary file.
Check and adjust the file permissions: Make sure that the binary file has the correct file permissions. The binary file should have the executable permission for the user, group, and others. To change the file permissions, use the
chmod +x /path/to/your/binary
Rebuild the Docker container: After applying the appropriate solution, rebuild the Docker container to ensure that the changes take effect. Run the following command in your terminal:
docker build -t your-image-name .
Test the Docker container: After rebuilding the Docker container, run it to ensure that the
standard_init_linux.go:178 error no longer occurs. Use the following command to run the Docker container:
docker run -it --rm your-image-name
1. What is the Exec User Process in Docker?
The Exec User Process is the main process that runs inside a Docker container. It is responsible for executing the commands and binaries specified in the Dockerfile or the
docker run command.
2. How can I determine the architecture of my Docker container?
You can determine the architecture of your Docker container by running the
uname -m command inside the container. This command will display the architecture of the container's kernel.
3. Can I use a single Docker container for multiple architectures?
Yes, you can create a multi-architecture Docker container using the Docker Buildx plugin. This plugin allows you to build Docker images that support multiple architectures, such as ARM and x86.
4. How can I recompile a binary file for a different architecture?
To recompile a binary file for a different architecture, you'll need to use a cross-compiler toolchain that supports the target architecture. For example, you can use the
gcc compiler with the appropriate target architecture flag to recompile a binary file.
5. Can I run x86-based Docker containers on an ARM-based system?
Yes, you can run x86-based Docker containers on an ARM-based system using an emulator like QEMU. However, this method can result in reduced performance compared to running the container on a native x86-based system.
By following this comprehensive guide, you should now be able to resolve the
standard_init_linux.go:178 error, also known as the "Exec Format Error," in the Exec User Process. Remember to verify the binary file's architecture, integrity, and file permissions before rebuilding the Docker container to ensure the error no longer occurs.
