Dockerized – Run CLI tools without installation
Dockerized is like npx for unix tools: Run popular cli tools without installation. Example: dockerized npm init dockerized python2 somescript.py Run an older version of a tool: NODE_VERSION=15.0 dockerized node Use cases: - Maintaining multiple versions of an app - Installing without polluting host machine - Quickly run some commands you may not have installed Features: - intuitive use. Just the original command, but with 'dockerized' in front. - dockerized apps can access the current directory and read/modify files, just like native apps. - no need to know which docker image this…
In plain words
Dockerized is a tool that runs command-line utilities through Docker without requiring installation on the host machine. Users prefix their usual commands with "dockerized" to execute tools like Node.js, Python, or npm in isolated containers. It supports specific version management, allows applications to access and modify files in the current directory like native tools, and automatically cleans up containers after use. This approach is useful for developers who want to maintain multiple tool versions, avoid cluttering their system, or quickly run commands without setup.

In the maker’s words, at launch
Dockerized is like npx for unix tools: Run popular cli tools without installation.

Just the original command, but with 'dockerized' in front. - dockerized apps can access the current directory and read/modify files, just like native apps. - no need to know which docker image this package comes from. - support for tools which don't have an official docker image. - container cleaned up after use. - ability to specify the version. - version specification per directory (share exact versions with your team mates). The inner workings are pretty simple, it's just a docker-compose file. As expected with dockerization, there are limitations related to networking, and file persistence (outside current dir), but it can make life easy for simple scenarios. Pull requests welcome!

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
