刪除 network

  1. 要刪除網路 selfservice 是用戶 demo 創建，所以先載入用戶 demo 的環境變數。 
    [root@controller ~]# . demo.token
  2. 要刪除網路是 selfservice。 
    [root@controller ~]# openstack network list
+--------------------------------------+-------------+--------------------------------------+
| ID                                   | Name        | Subnets                              |
+--------------------------------------+-------------+--------------------------------------+
| 3d2fe8f3-6871-4072-8688-4c83f597cda1 | selfservice | 37adab37-d710-406f-bdfa-66c2a4d13203 |
+--------------------------------------+-------------+--------------------------------------+
\end{enumerate}
\item 列出 ports，兩個 ports 於 subnet 37adab37-d710-406f-bdfa-66c2a4d13203，這是 selfservice 的 subnet。
\begin{myverbatim}
[root@controller ~]# openstack port list
+--------------------------------------+------+-------------------+-------------------------
| ID                                   | Name | MAC Address       | Fixed IP Addresses

+--------------------------------------+------+-------------------+-------------------------
--------------------------------------------------+--------+
                                                  | Status |
--------------------------------------------------+--------+

 subnet_id='37adab37-d710-406f-bdfa-66c2a4d13203' | ACTIVE |
--------------------------------------------------+--------+
\end{enumerate}
\item 以 port delete 刪除 port，port b1ba39ec-4646-46b6-850c-13ab5cfd9c3f 無法刪除，原於是其為 router 的 gateway。
\begin{myverbatim}
[root@controller ~]# openstack port delete 92485f50-e5c0-471a-9f24-ba1355d0f36c
[root@controller ~]# openstack port delete b1ba39ec-4646-46b6-850c-13ab5cfd9c3f

device_id=53bc7576-bcee-4ad4-ae06-d18d9be372a2)
1 of 1 ports failed to delete.
\end{enumerate}
\item router list 列出 router，但一樣無法刪除。
\begin{myverbatim}
[root@controller ~]# openstack router list
+--------------------------------------+--------+--------+-------+-------------+-------+----------------------------------+

+--------------------------------------+--------+--------+-------+-------------+-------+----------------------------------+
[root@controller ~]# openstack router delete 53bc7576-bcee-4ad4-ae06-d18d9be372a2
Failed to delete router with name or ID '53bc7576-bcee-4ad4-ae06-d18d9be372a2':

\end{enumerate}
\item router 先 unset gateway。
\begin{myverbatim}
[root@controller ~]# openstack router unset --external-gateway 53bc7576-bcee-4ad4-ae06-d18d9be372a2
\end{enumerate}
\item 再查一下 ports，除原無法刪除的 b1ba39ec-4646-46b6-850c-13ab5cfd9c3f，又自動生成 e34033f0-dfef-40d5-933d-b7a5584cca94。
\begin{myverbatim}
[root@controller ~]# openstack port list
+--------------------------------------+------+-------------------+-------------------------

 subnet_id='37adab37-d710-406f-bdfa-66c2a4d13203' | BUILD  |
--------------------------------------------------+--------+
\end{enumerate}
\item 將 port b1ba39ec-4646-46b6-850c-13ab5cfd9c3f 從 router b1ba39ec-4646-46b6-850c-13ab5cfd9c3f 中移除。
\begin{myverbatim}
[root@controller ~]# openstack router remove port 53bc7576-bcee-4ad4-ae06-d18d9be372a2 b1ba39ec-4646-46b6-850c-13ab5cfd9c3f
\end{enumerate}
\item 再查一下 ports，只剩剛剛生成 e34033f0-dfef-40d5-933d-b7a5584cca94。
\begin{myverbatim}
[root@controller ~]# openstack port list
+--------------------------------------+------+-------------------+-------------------------
| ID                                   | Name | MAC Address       | Fixed IP Addresses

 subnet_id='37adab37-d710-406f-bdfa-66c2a4d13203' | BUILD  |
--------------------------------------------------+--------+
\end{enumerate}
\item port e34033f0-dfef-40d5-933d-b7a5584cca94 不是 gateway，直接以 port delete 刪除，直到沒有列出 port。
\begin{myverbatim}
[root@controller ~]# openstack port delete e34033f0-dfef-40d5-933d-b7a5584cca94
[root@controller ~]# openstack port list
\end{enumerate}
\item 查詢 subnet id 37adab37-d710-406f-bdfa-66c2a4d13203。
\begin{myverbatim}
[root@controller ~]# openstack subnet list
+--------------------------------------+-------------+--------------------------------------+---------------+
| ID                                   | Name        | Network                              | Subnet        |
+--------------------------------------+-------------+--------------------------------------+---------------+

+--------------------------------------+-------------+--------------------------------------+---------------+
\end{enumerate}
\item 刪除 subnet 37adab37-d710-406f-bdfa-66c2a4d13203。
\begin{myverbatim}
[root@controller ~]# openstack subnet delete 37adab37-d710-406f-bdfa-66c2a4d13203
\end{enumerate}
\item 查詢 network id 是 3d2fe8f3-6871-4072-8688-4c83f597cda1。
\begin{myverbatim}
[root@controller ~]# openstack network list
+--------------------------------------+-------------+---------+

+--------------------------------------+-------------+---------+
\end{enumerate}
\item 刪除 network 3d2fe8f3-6871-4072-8688-4c83f597cda1。
\begin{myverbatim}
[root@controller ~]# openstack network delete 3d2fe8f3-6871-4072-8688-4c83f597cda1
\end{enumerate}
\item 再查 network 已是空的。
\begin{myverbatim}
[root@controller ~]# openstack network list
