This solves the common problem of dependency pollution and environment drift across projects. Setup involves adding a .devcontainer folder, choosing a base image or Dockerfile, and reopening the project in the container via the Command Palette. Tradeoffs include slower first builds, limited hardware/GUI access, and added complexity for multi-service setups requiring Docker Compose. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the VS Code Dev Containers feature and how does it work? Dev Containers is a VS Code feature that runs each project inside its own container with pre-configured language versions, dependencies, and tools. A .devcontainer folder holds a devcontainer.json file that can reference a prebuilt image, Dockerfile, or Docker Compose setup, define extensions to install, ports to forward, and post-creation commands. Running 'Dev Containers: Reopen in Container' rebuilds and connects the project to that isolated environment. _daily.dev surfaces practical dev container workflows for developers tired of tangled local environments._ ### What are the downsides of using VS Code Dev Containers for a project? The first container build is slow because Docker must download the image and install everything, though later launches are faster if the container persists. Extra configuration is often needed for hardware access, graphical applications, or services running outside the container, and multi-service projects with a database, backend, and frontend may require multiple containers coordinated through Docker Compose. _Weighing container isolation against setup complexity is easier with daily.dev's coverage of developer tooling tradeoffs._ ## Similar posts on daily.dev - [Run Your Project in a Dev Container, in Zed — Zed's Blog](https://daily.dev/posts/run-your-project-in-a-dev-container-in-zed-zed-s-blog-z2useuhjn) · Zed · 85 upvotes · 7 comments - [I automated my entire dev startup with one VS Code shortcut, and the terminal became optional](https://daily.dev/posts/i-automated-my-entire-dev-startup-with-one-vs-code-shortcut-and-the-terminal-became-optional-zq0l6bosq) · XDA Developers · 4 upvotes · 1 comments - [Debug Docker Builds with Visual Studio Code](https://daily.dev/posts/debug-docker-builds-with-visual-studio-code-uxi8tkhao) · Docker · 7 upvotes · 0 comments --- Tags: [#docker](https://daily.dev/tags/docker), [#containers](https://daily.dev/tags/containers), [#vscode](https://daily.dev/tags/vscode) [View this post on daily.dev](https://daily.dev/posts/my-favorite-vs-code-upgrade-isn-t-another-ai-extension-it-s-something-even-better-rgep1di7c) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"My favorite VS Code upgrade isn’t another AI extension, it's something even better","url":"https://daily.dev/posts/my-favorite-vs-code-upgrade-isn-t-another-ai-extension-it-s-something-even-better-rgep1di7c","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/my-favorite-vs-code-upgrade-isn-t-another-ai-extension-it-s-something-even-better-rgep1di7c"},"datePublished":"2026-07-21T15:02:50.674Z","dateModified":"2026-09-14T06:13:54.596Z","description":"Dev Containers in VS Code let you run each project inside its own isolated container with the correct language versions, dependencies, extensions, and tools...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ca3a65f86b81475c156d29878320fa28?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ca3a65f86b81475c156d29878320fa28?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"XDA Developers","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"XDA Developers","logo":"https://media.daily.dev/image/upload/s--kCg6yyAP--/f_auto,q_auto/v1774964407/logos/xda-developers?_a=BAMAMiWQ0","url":"https://daily.dev/sources/xda-developers"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/my-favorite-vs-code-upgrade-isn-t-another-ai-extension-it-s-something-even-better-rgep1di7c","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":2},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"docker,containers,vscode","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"XDA Developers","item":"https://daily.dev/sources/xda-developers"},{"@type":"ListItem","position":3,"name":"My favorite VS Code upgrade isn’t another AI extension, it's something even better"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/my-favorite-vs-code-upgrade-isn-t-another-ai-extension-it-s-something-even-better-rgep1di7c#faq","mainEntity":[{"@type":"Question","name":"What is the VS Code Dev Containers feature and how does it work?","acceptedAnswer":{"@type":"Answer","text":"Dev Containers is a VS Code feature that runs each project inside its own container with pre-configured language versions, dependencies, and tools.
