Building python wheel via docker compose on aws ec2 gets stuck

When building a Python wheel via Docker Compose on AWS EC2, it is not uncommon to encounter issues that cause the process to get stuck. This can be frustrating, especially when you are trying to deploy your application or package. In this article, we will explore three different solutions to this problem, each with its own advantages and disadvantages.

Solution 1: Increase EC2 Instance Size

One possible reason for the build process getting stuck is that the EC2 instance does not have enough resources to handle the workload. By increasing the instance size, you can allocate more CPU and memory to the build process, potentially resolving the issue.


# Increase EC2 instance size
# Add code snippet here

This solution is relatively straightforward and does not require any changes to your Docker Compose configuration. However, it may incur additional costs if you need to upgrade to a larger instance type.

Solution 2: Optimize Docker Compose Configuration

Another possible reason for the build process getting stuck is that the Docker Compose configuration is not optimized for the workload. By tweaking the configuration, you can improve the performance and stability of the build process.


# Optimize Docker Compose configuration
# Add code snippet here

This solution requires you to analyze and modify your Docker Compose configuration. It may involve adjusting resource limits, optimizing container dependencies, or fine-tuning other parameters. While it may take some time to identify the optimal configuration, it can lead to significant improvements in the build process.

Solution 3: Use a Dedicated Build Server

If the previous solutions do not yield satisfactory results, you can consider setting up a dedicated build server specifically for building Python wheels. This server can have higher specifications and be solely dedicated to the build process, minimizing any potential resource constraints.

# Add code snippet here

This solution requires additional infrastructure setup and maintenance. However, it provides the most control over the build process and allows you to fine-tune the server’s specifications to meet your specific requirements.

After considering these three solutions, the best option depends on your specific situation. If you are looking for a quick fix and have the budget, increasing the EC2 instance size may be the most straightforward solution. If you have the time and expertise to optimize your Docker Compose configuration, Solution 2 can provide long-term benefits. Finally, if you require maximum control and performance, setting up a dedicated build server (Solution 3) may be the most suitable choice.

Ultimately, the best solution will depend on factors such as budget, time constraints, and the complexity of your build process. It is recommended to evaluate each option carefully and choose the one that aligns with your specific needs and resources.

  1. Solution 3 seems like a no-brainer! A dedicated build server would definitely save me from all the docker-compose troubles.

    1. I couldnt disagree more. Relying on a dedicated build server sounds like an unnecessary hassle. Docker-compose is a powerful tool that just needs a bit of patience to master. Dont give up on it so easily!
