# Felis one-line bootstrap installer.

# curl -fsSL <raw-url>/deploy/bootstrap.sh | sudo bash

|
# Brings a fresh single-node Linux host from nothing to a running Felis control
|
|
# plane: it installs whatever is missing (picking apt/dnf/yum/zypper/pacman by OS), provisions a
|
|
# swap file on tiny hosts, then configures Docker, k3s and PostgreSQL, builds and
|
|
# imports the felis image, runs database migrations and applies the rendered
|
|
# install bundle (CRD + namespaces + RBAC + NetworkPolicies + control-plane
|
|
# Deployments + in-cluster registry).
|
|
#
|
|
# The recommended entrypoint is now `sudo felis setup`, which wraps this
|
|
# bootstrap in a TUI and then continues to the Owner/edge setup. This script
|
|
# remains usable directly for raw host provisioning.
|
|
#
|
|
# At the start it asks what to install:
|
|
# [1] Felis — the full control plane described above.
|
|
# [2] Felis-nano — ONLY the Yggdrasil hasJoined multiplexer (`felis nano`) as a
|
|
# systemd service: no k3s, no Postgres, no bundle. For a
|
|
# third-party server operator who just wants multi-Yggdrasil
|
|
# auth federation. Preselect non-interactively with
|
|
# FELIS_INSTALL_MODE=nano.
|
|
#
|
|
# The script is idempotent: re-running it converges rather than duplicating, and
|
|
# generated secrets are persisted to /etc/felis/secrets.env so reruns reuse them.
|
|
#
|
|
# Tunables (export before running to override the demo defaults):
|
|
# FELIS_INSTALL_MODE full|nano — skip the prompt (default: ask on a tty, else full)
|
|
# FELIS_NANO_LISTEN listen addr for `felis nano` (default: 127.0.0.1:8081 — loopback
|
|
# only; set a private-network IP to serve an off-host proxy)
|
|
# FELIS_GO_VERSION Go toolchain used to build the nano binary (default: 1.26.4)
|
|
# FELIS_REPO_URL git URL to build from (raw script mode only)
|
|
# FELIS_REF branch/tag/sha (raw script mode only)
|
|
# FELIS_IMAGE local image tag (default: felis:demo — never :latest)
|
|
# FELIS_ROOT_DOMAIN deployment root domain (default: <node-ip>.nip.io)
|
|
# FELIS_PANEL_NODEPORT local HTTPS panel/API NodePort (default: 30443)
|
|
# FELIS_EGRESS_MODE loadbalancer|nodeport (default: nodeport — no MetalLB on a demo box)
|
|
# PKG_LOCK_TIMEOUT seconds to wait for package-manager locks (default: 900)
|
|
# APT_LOCK_TIMEOUT legacy alias for PKG_LOCK_TIMEOUT
