VSCode + Dev Containers are a great way to create custom environments without modifying our actual system.

They provide a consistent development environment, ensure dependencies are managed correctly, and make it easy to share setups with your team.

Here are some configurations you can use to create them.

Vapor# 

{
    "name": "Swift",
    "image": "swift:latest",
    "features": {
        "ghcr.io/devcontainers/features/common-utils:2": {

            "upgradePackages": "false"
        },

        }
    },
    "runArgs": [
        "--cap-add=SYS_PTRACE",

                "sswg.swift-lang",

        }
    },

}
