✨ runc-create(8) ✨

okay bestie, you found the runc-create page in the System Manager's Manual and honestly? iconic. let's get into it 💅

🌸 NAME 🌸

runc-create — create a container 🫶

---

✨ SYNOPSIS ✨

runc create [option ...] container-id

---

🎀 DESCRIPTION 🎀

so the create command literally creates an instance of a container from a bundle. that's the whole vibe. 🦋

and what even is a bundle, you ask? it's a directory, and inside it there's a specification file named config.json, plus a root filesystem. that's it, that's the bundle. main character energy fr fr.

---

💖 OPTIONS 💖

• --bundle|-b path — the path to the root of the bundle directory. default is the current directory, no cap. 🍓
• --console-socket path — the path to an AF_UNIX socket that's gonna receive a file descriptor referencing the master end of the console's pseudoterminal. yes it's giving very specific. go read docs/terminals at https://github.com/opencontainers/runc/blob/master/docs/terminals.md for the full tea. 🧚
• --pid-file path — tell it which file to write the initial container process' PID to. like, put the PID here, bestie. 📝
• --no-pivot — do NOT use pivot root to jail the process inside the rootfs. > ⚠️ bestie listen to me: this should not be used except in exceptional circumstances, and it may be unsafe from the security standpoint. i'm not being dramatic, that's just the facts. 💀
• --no-new-keyring — don't create a new session keyring for the container. heads up though: this will cause the container to inherit the calling process's session key. so like, it's a whole thing. 🔑
• --preserve-fds N — pass N additional file descriptors to the container (stdio + $LISTEN_FDS + N in total). default is 0. the math is mathing, don't worry. ✨
