Set Env Vars with Hive

This doc shows how to use hive to store env vars in Flow’s local personal env store. These values are global (not tied to a repo) and are later pulled during deploy.

Prereqs

hive installed (f deploy in ~/code/lang/mbt/hive)
env-help installed (f deploy-help in ~/code/lang/mbt)
Flow local env backend (default on this machine)

Recommended: editor-based paste (multi-line)

This opens your editor (Zed if installed, else nano), then saves and closes.

bash

hive --paste env

Paste lines like:

bash

STREAM_SERVER_HETZNER_HOST=u533855.your-storagebox.de
STREAM_SERVER_HETZNER_USER=u533855
STREAM_SERVER_HETZNER_PATH=/backups/streams
STREAM_SERVER_HETZNER_PORT=23

Save and close the editor to apply.

One-liner (single line)

bash

hive env STREAM_SERVER_HETZNER_HOST=u533855.your-storagebox.de STREAM_SERVER_HETZNER_USER=u533855 STREAM_SERVER_HETZNER_PATH=/backups/streams STREAM_SERVER_HETZNER_PORT=23

Pipe (non-interactive)

bash

cat <<'EOF' | hive --paste env
STREAM_SERVER_HETZNER_HOST=u533855.your-storagebox.de
STREAM_SERVER_HETZNER_USER=u533855
STREAM_SERVER_HETZNER_PATH=/backups/streams
STREAM_SERVER_HETZNER_PORT=23
EOF

Verify

bash

f env list

This lists envs in personal + production scope (values are masked).

Deploy using Flow env store

From the repo using these envs (example: stream server):

bash

cd ~/code/lang/cpp/stream
f deploy host

Flow writes /opt/stream/.env on the host using the local env store.

Notes

Env vars are stored at: ~/.config/flow/env-local/personal/production.env
Use hive --paste env whenever you need multi-line input.
