• You: How do I increase memory of the build

Bot:
To increase the memory of the build in Defang, you can adjust the memory settings in your project's configuration file. This involves specifying higher memory limits for the services that require more resources. If you're using Docker, for example, you can set memory limits directly in the Docker Compose file under the services section for each service. Here’s a basic example:

version: '3'
services:
  your-service:
    image: your-image
    mem_limit: 512m

In this snippet, mem_limit is set to 512 megabytes. You can adjust this value according to your needs.

If you encounter any issues while making these adjustments, the improved Debug Assistant in Defang can help you troubleshoot and resolve any configuration errors more effectively.

• You: What is shm_size used for in defang compose file?

Bot:
The shm_size in the Defang compose file is used to specify the size of the /dev/shm partition for a service. This setting is important for applications that require a specific amount of shared memory, such as databases or applications that perform heavy data processing. By configuring shm_size, you can ensure that the container has enough shared memory to handle the application's needs, which can help in improving performance and preventing issues related to memory constraints.
