I built a devcontainer that makes it safe(-er) to run Claude Code with "--dangerously-skip-permissions" for Elixir/Phoenix projects and it comes with Tidewave too! It's based on Anthropic's reference but made safer and tailored to #ElixirLang

Picking up the Veilid containerized developer workflow to tinker on it for a few minutes before I turn in for evening bookworm time.
Let's start with creating the .devcontainer directory, devcontainer.json, and devcontainer Dockerfile.

Okay peeps, I finally added docs to the Devcontainer repository.
I've been trying to document the Konductor repo and just kept failing until the devcontainer that powers Konductor was finally documented.
Happy Saturday 🌈😊✨

Uploaded a demo on how to use nodejs/devcontainer!
- Testing a mounted dev branch on a different OS
- No need to build V8 from scratch on a fresh checkout (usually)

Yesterday I've built the multiarch devcontainer variant that would allow macOS/arm64 users to just
1. open a repo in vscode
2. click reopen in devcontainer
and start using containerlab right away.

I've been practicing the different LLM augmented dev interfaces across VSCode, Cursor, and Zed IDEs.
This morning I needed to fix a github.com/ContainerCraft/devcontainer neovim image build issue but tbh I didn't feel like going back to fix old stuff when I'm in the mood to work new shiny instead 🧵

VSCode, the Dev Containers extension & its "Clone Repository in Container Volume" command are lovely for compartmentalizing your local dev work.
For example, the Preact Signals repo's (github.com/preactjs/sig...) .devcontainer setup handles things like installing a containerized browser for tests.

✋- devcontainer for keeping things consistent (e.g. npm, etc) and we actually run other containers inside of that. basically one click up and running after installing Docker/ Orbstack and putting the devcontainer extension in VSCode/ Cursor

I don’t run any external code outside a container. 👌
I’m using workmux w/ sandbox + a custom Dockerfile. it has:
⚪ network-level allow-list
⚪ auto sandbox creation/shutdown ✨
⚪ auto worktrees
⚪ docker or apple container
I expose only a read-only gh token in the container.
