phoenix_container_example VS rocker-versioned2

It's particularly useful for testing a set of microservices.

See https://github.com/cogini/phoenix_container_example for a full example.

I use distroless images based on Debian or Ubuntu, e.g., https://github.com/cogini/phoenix_container_example

The result is images the same size as Alpine, or smaller, without the incompatibilities. I think Alpine is a dead end.

Here is a full-featured example of building images in GitHub Actions that includes optimized caching: https://github.com/cogini/phoenix_container_example/blob/master/.github/workflows/ci-ghcr.yml

Here are some examples of using GitHub actions to build, or call hosted runners in AWS to build Arm images, and using OIDC to manage AWS credentials: https://github.com/cogini/phoenix_container_example/blob/master/.github/workflows/

Parameter Store is a good place to store things. ECS can read from it and set variables. This is a complete example of using Terraform to manage infrastructure with EC2 or ECS: https://github.com/cogini/multi-env-deploy Here is an app that runs in ECS: https://github.com/cogini/phoenix_container_example This task file sets env vars based on parameter store: https://github.com/cogini/phoenix_container_example/blob/master/ecs/taskdef.json

Here is a complete example project which shows how to use Earthly and Visual Studio Code .devcontainer: https://github.com/cogini/phoenix_container_example

I am heavily using multi-stage builds, e.g.: https://github.com/cogini/phoenix_container_example/blob/master/deploy/Dockerfile.alpine

R is kinda difficult and I haven’t cracked this one. Currently we’re using the rocker based ones[1] but they are based on Ubuntu and include a lot of stuff we don’t need at runtime. I’ll look into creating a more minimal R base images that’s based on Debian-slim.
