Do you increase container resources when expanding functionality that consumes more resources?

When expanding functionality that requires more resources, it is advisable to consider increasing the container's resources to ensure the application's stable operation. For example, if the container is limited in memory or CPU, and new functionality leads to increased load, performance degradation or failures may occur without resource augmentation.

However, increasing resources should be justified and accompanied by monitoring. Sometimes, code optimization or load redistribution can be more effective solutions. It is also important to consider infrastructure limitations and the cost of resource increase.

An example in Docker Compose for increasing memory and CPU:

services:
  app:
    image: my-java-app
    deploy:
      resources:
        limits:
          cpus: '1.5'
          memory: 1024M
