# swiro
swiro is a switching route tool for AWS to realize VIP (Virtual IP) with Routing-Based High Availability pattern.
This pattern is possible to perform failover (switching of the connection destination) of the EC2 redundant across the subnet (AZ).
## Usage
* List routes
```
$ swiro list
```
* Switching routes
```
$ swiro switch -r rtb-xxxxxx -v 10.0.0.1 -I i-xxxxxx
```
## Example
### List routes
```
$ swiro list
===> Route Table: route_table_1 (rtb-xxxxxx1)
---> Virtual IP: 10.0.0.1/32 =======> src_instance_1 (i-yyyyyy1)
---> Virtual IP: 10.0.0.2/32 =======> src_instance_2 (i-yyyyyy2)
===> Route Table: route_table_2 (rtb-xxxxxx2)
---> Virtual IP: 10.0.0.3/32 =======> src_instance_3 (i-yyyyyy3)
```
### Switching routes
In most cases you can switch the routing with the Route Table ID as follows:
```
$ swiro switch -r rtb-xxxxxx -v 10.0.0.1 -I i-xxxxxx
Switch the route below setting:
===> Route Table: route_table (rtb-xxxxxx)
---> Virtual IP: 10.0.0.1 -------- Src: src_instance (i-yyyyyy)
\\
======> Dest: i-xxxxxx
Are you sure? (y/n) [y]: y
Success!!
```
You can also switch by specifying Route Table Name instead of Route Table ID.
```
$ swiro switch -r route_table -v 10.0.0.1 -I dest_instance
```
