CI/CD on AWS extremely slow

Question

Hi,

So I've configured CodePipeline: connection to GitHub, CodeBuild (builds a Docker image and pushes it to ECR), and deployment using Amazon ECS on a Fargate cluster via service with task number = 1, minimum healthy=50%, maximum healthy=140%.

It takes astonishing 8 minutes(!) to build and push a simple container, also from the logs it is obvious the Docker layer cache is not used.
And then the deployment stage takes ~10 minutes.

This is unreal. Is it supposed to be that slow? Are there any ways to make it faster?

Thank you.

Hi!

> it is obvious the Docker layer cache is not used

Why not? can you share the Buildspec file?

Please read the article bellow and take a look at the usage of **cache-from** during docker build.

The basic idea is pull the previous image from ECR and use it as cache from the current build with the  **cache-from** parameter.
