# AWS Lambda - Static outgoing IP address
2+
3+
This repository is created according to article [AWS Lambdas with a static outgoing IP](http://techblog.financialengines.com/2016/09/26/aws-lambdas-with-a-static-outgoing-ip/) by Ivonne Roberts. By using this repository you do not have to create all AWS resources by hand, but you can let AWS CloudFormation to do it for you. To see CloudFormation config open `serverless.yml` file. Steps mentioned in the article are marked in this file, so that it is easier to follow.
4+
5+
## Requirements:
6+
7+
- curl
8+
- docker
9+
- docker-compose
10+
11+
## Usage:
12+
13+
Create `.env` file:
14+
```
15+
mv .env.template .env
16+
```
17+
Set environment variable values in `.env` file:
18+
|Variable|Description|
19+
|-|-|
20+
|AWS_ACCESS_KEY_ID|Access key ID for serverless framework|
21+
|AWS_SECRET_ACCESS_KEY|Access key for serverless framework|
22+
|STAGE|name of deployment stage (e.g dev)|
23+
|REGION|deployment region (e.g us-west-1)|
24+
25+
Clone repository:
26+
```
27+
git clone https://github.com/ikim23/aws-lambda-static-ip.git
28+
```
29+
Install NPM modules:
30+
```
31+
docker-compose run install
32+
```
33+
Deploy app to AWS:
34+
```
35+
docker-compose run deploy
36+
```
37+
Trigger caller function to get Elastic IP address (static IP):
38+
```
39+
curl -XGET https://<API_IP>.execute-api.<REGION>.amazonaws.com/<STAGE/call
40+
```
