# Stage 1 base config + hardening, end to end, for a single fresh PVE host.
|
|
# Runs the individual scripts in order. Idempotent - safe to re-run.
|
|
#
|
|
# If ADMIN_USER and ADMIN_SSH_KEY are set, a Linux system user is created
|
|
# with SSH key access and sudo before SSH hardening runs - so key-based
|
|
# login is in place before password auth is disabled. If they are not set,
|
|
# a reminder is printed at the end to run setup-linux-admin-user.sh manually
|
|
# (but do this BEFORE disconnecting, since password auth will be disabled).
|
|
#
|
|
# Usage:
|
|
# MGMT_CIDR=192.168.2.0/24 ./bootstrap.sh
|
|
# MGMT_CIDR=192.168.2.0/24 ADMIN_USER=wayne ADMIN_SSH_KEY="ssh-ed25519 ..." ./bootstrap.sh
