- Hot-updates credentials in memory instantly and persists them to a plugin-owned state file under
$DSH_HOME/plugins/dsh-plugin-auth-webserver/, so they survive restarts without touching your config layers.

Installation
Install the bundle into a profile with dsh plugin:
# From a git host (pin a commit so later pushes cannot change what runs):
dsh plugin --profile web add github:kolawong/dsh-plugin-auth-webserver#<commit-sha>
# Or from a tarball / npm registry once published:
dsh plugin --profile web add ./dsh-plugin-auth-webserver-0.3.0.tgz
dsh plugin --profile web add dsh-plugin-auth-webserver
The package declares dsh.bundle, so dsh plugin appends it to the
profile's bundle list automatically; its patch disables the stock
webserver row and inserts the auth-gated server. Then boot:
dsh --profile web
Open http://your-server-ip:3080 to see the login page.
Configuration
Every option has a default; override the webserver-auth row in your
profile's own patch ($DSH_HOME/profiles/web/cordis.patch.yml), which is
applied after every bundle layer:
- id: webserver-auth
config:
host: '0.0.0.0'
port: 3080
username: 'admin'
password: 'your_secure_password'
Changes made in the Web UI settings card apply immediately and are stored
in $DSH_HOME/plugins/dsh-plugin-auth-webserver/state.json (mode 0600).
Environment variables DSH_AUTH_USER and DSH_AUTH_PASS override both the
config and the saved state.
