Build docker run and docker build commands visually — ports, volumes, env vars, and flags, live-previewed and copy-ready.

Generated Command
Nothing you enter here is sent to a server — the command is assembled entirely in your browser.
Your Data Never Leaves Your Device
Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.
The Docker Command Builder turns the flags you'd otherwise look up every time — port mappings, volume mounts, environment variables, restart policy — into a form. Switch between docker run and docker build and the command updates live as you type.
Values with spaces or special characters are automatically shell-quoted, and default or empty options are omitted from the output, so the generated command is always a clean, minimal string you can paste straight into a terminal.
FAQ
It lets you pick options — image, ports, volumes, environment variables, restart policy, and flags — and live-generates the correct docker run or docker build command, so you don't have to memorize flag order or syntax.
No. The command string is assembled entirely in your browser using JavaScript — nothing you type is uploaded anywhere.
Ports are generated as -p host:container (with /udp appended only if you choose UDP), and volumes as -v host:container (with :ro appended only for read-only mounts) — matching Docker's standard host:container syntax.
The builder automatically wraps values that contain spaces, quotes, or shell-special characters in single quotes and escapes embedded quotes, so the generated -e flags are safe to paste directly into a terminal.
Not yet — this tool currently focuses on docker run and docker build, the two most commonly hand-typed Docker commands. Support for docker exec or a Compose file generator may be added as a separate tool.
