  • Show HN: Lapdev, a new open-source remote dev environment management software
    7 projects | news.ycombinator.com | 23 Mar 2024
    Hi, Lapdev dev here. Let me try to answer your question.

    It's installed on a remote server so it provides remote environments. If you use VSCode remote, then you can "open" it through VSCode remote ssh.

    The environment that Lapdev provides essentially is a container (other format is on the roadmap) with things pre-installed as defined in Devcontainer(https://containers.dev/) format.

  • Show HN: Flox 1.0 – Open-source dev env as code with Nix
    17 projects | news.ycombinator.com | 13 Mar 2024
    Happy to take this one, as I am one of the cofounder of Daytona.

    Daytona solves all the automation and provisioning of the dev environment, actually wrote an article here laying out exactly what we do: https://www.daytona.io/dotfiles/diy-guide-to-transform-any-m...

    Daytona currently supports only the dev container (https://containers.dev/) "dev env infrastructure as code" standard, but are looking to support others such as devfile, nix and flox.

    Hope this helps

    The full usage of the container means that you'll do the development inside the container. All the tools for development need to be installed inside the container. One of the technologies that leverage this approach is Devcontainers.

  • Dev Containers: Open, Develop, Repeat...
    9 projects | dev.to | 30 Oct 2023
    How it works? Dev Containers is a specification based on Docker. This specification describes a metadata file (devcontainer.json), which defines how the project (Docker container, IDE settings, plugins, etc) is set up.

    2 projects | dev.to | 24 Oct 2023
    Codespaces is built to run Dev Containers, an open standard for Development Containers. The Dev Container will reference a Docker build file, which describes the software and services our app is running on. It also defines things related to our development environment, including IDE plugins, network ports, and more.

  • Microsoft Docker Development Container Templates
    8 projects | news.ycombinator.com | 13 Aug 2023
    I do not know why someone shared this repo, there is nothing special about it other than containing some start templates. I would start here for understanding Dev Containers: https://containers.dev

    If you have a scenario where using a container as your development environment makes sense, this is some tooling that can improve the developer experience vs just using plain Docker and Docker Compose.

    8 projects | news.ycombinator.com | 13 Aug 2023
    I see it as being similar to the relationship between Vagrant and Virtual Machines.

    You can use plain Dockerfiles if you prefer, dev containers provides some tooling to smooth out the rough edges of using Docker to host your dev environment including mounting your source code into the container etc. Details are at: https://containers.dev
