+# Netmaker CI helper: bring WireGuard up/down and manage ephemeral client lifecycle.
|
|
|
+# Subcommands:
|
|
|
+# up - fetch config, capture Client-ID, bring interface up, save state
|
|
|
+# down - bring interface down, delete local conf, delete client via API
|
|
|
+#
|
|
|
+# Env vars (can be overridden by flags):
|
|
|
+# NETMAKER_BASE_URL (required) e.g. https://nm.example.com or pass --base-url
|
|
|
+# NETMAKER_NETWORK (required) e.g. corpnet or pass --network
|
|
|
+# NETMAKER_API_JWT (required) Bearer token or pass --jwt
|
|
|
+# WG_IFACE (default netmaker) or pass --iface
|
|
|
+# WG_CONF_DIR (default /etc/wireguard) or pass --confdir
|
|
|
+# NETMAKER_STATE_FILE (default RUNNER_TEMP or /tmp)
|
|
|
+# You may also pass --client-id on `down` to avoid relying on the state file.
