DOCKER-BUILDX(1)

💖 DOCKER-BUILDX — the manual, but make it bestie 💖

okay so. this is the docker-buildx manual page, from the DOCKER-BUILDX(1) section of the manual, and honestly? it's giving main character energy for your whole build pipeline. let's get into it 🎀

---

✨ NAME ✨

docker-buildx — Docker Buildx

like. that's the whole name. short, iconic, no notes. 💅

---

🦋 SYNOPSIS 🦋

docker buildx

that's it bestie, that's the whole invocation. just docker buildx and the universe opens up 🌸

---

🌈 DESCRIPTION 🌈

Extended build capabilities with BuildKit

fr fr that's the vibe: Buildx hands you extended build powers, and the engine doing all the heavy lifting underneath is BuildKit. no cap. 🔥

---

👑 OPTIONS 👑

• --builder="" — Override the configured builder instance. yes, you can just point at a different builder than the one you set up before, and it'll use that one instead. lowkey the most powerful little flag here. 💖
• -h, --help[=false] — help for buildx. the classic. the moment you forget everything, you type this. default is false, so it does nothing unless you ask for it. 🫶

---

🍓 EXAMPLE 🍓

Override the configured builder instance (--builder) {#builder}

You can also use the BUILDX_BUILDER environment variable.

so like — instead of passing --builder every single time, you can just set the env var and let it live in your shell rent-free. the way that's convenient?? obsessed. ✨
