apptainer(1) — the keyserver glow-up edition 💅

okay so real talk, this is the apptainer manual page, and today's main character is apptainer-keyserver-login. yes bestie, we're logging in. 🎀

---

✨ NAME ✨

apptainer-keyserver-login — login to a keyserver 🔑

like, that's it. that's the whole job. it gets you in. no cap.

---

✨ SYNOPSIS ✨

apptainer keyserver login [login options...]

so you call apptainer, then keyserver, then login, then whatever options you're feeling. the options are optional (iconic of them honestly), but the vibes are mandatory. 🦋

---

✨ DESCRIPTION ✨

the keyserver login command lets you log in to a specific keyserver. one keyserver. the one you point at. it's giving "I know exactly which server I'm here for" energy. 💖

---

✨ OPTIONS ✨

• -h, --help[=false] — help for login. when you're lost, press this. it's the group chat "what's going on" of flags. 🫶
• -p, --password="" — the password / token you authenticate with. default is "" (aka nothing, aka empty, aka no password yet bestie). 🔐
• --password-stdin[=false] — take the password from standard input instead. lowkey the safer way to do it so your secret isn't just sitting there in your shell history for the whole world to see. 🙈
• -u, --username="" — the username you authenticate with. and heads up: this one is required for Docker/OCI registry login. required. not optional. do not skip it. default is "". 💀

ngl, that last one is the classic "I forgot the username and nothing worked" moment. don't be that girl. 🧚

---

✨ EXAMPLE ✨

to login in to a keyserver, you literally just:

$ apptainer keyserver login --username foo https://mykeyserver.example.com

foo = your username, the URL = your keyserver. slay. that's the whole ritual. 🔥
