# Java SendGrid Email Sample for Google Compute Engine | ||
|
||
This sample demonstrates how to use [SendGrid](https://www.sendgrid.com) on | ||
[Google Compute Engine](https://cloud.google.com/compute/) | ||
|
||
See the [sample application documentaion][sample-docs] for more detailed | ||
instructions. | ||
|
||
For more information about SendGrid, see their | ||
[documentation](https://sendgrid.com/docs/User_Guide/index.html). | ||
|
||
[sample-docs]: https://cloud.google.com/compute/docs/tutorials/sending-mail/using-sendgrid | ||
|
||
## Running on Compute Engine | ||
|
||
To run the sample, you will need to do the following: | ||
|
||
1. [Create a SendGrid Account](http://sendgrid.com/partner/google). As of | ||
September 2015, Google users start with 25,000 free emails per month. | ||
1. Create a compute instance on the Google Cloud Platform Developer's Console | ||
1. SSH into the instance you created | ||
1. Update packages and install required packages | ||
sudo apt-get update && sudo apt-get install git-core openjdk-8-jdk maven | ||
1. Clone the repo | ||
git clone https://github.com/shun-fan/test-compute-sendgrid.git | ||
1. Configure your SendGrid settings in the java class (SENDGRID_API_KEY, SENDGRID_SENDER, TO_EMAIL) | ||
./sendgrid/src/main/java/com/example/compute/sendgrid/SendEmailServlet.java | ||
1. Navigate back to ./sendgrid and use maven to package the class as a jar | ||
mvn clean package | ||
1. Switch to the target directory with the jar file and enable execution on that file | ||
chmod +x compute-sendgrid-1.0-SNAPSHOT-jar-with-dependencies.jar | ||
1. Make sure that openjdk 8 is the selected java version | ||
sudo update-alternatives --config java | ||
1. Execute the jar file and send an email (make sure you are in the target folder) | ||
java -jar compute-sendgrid-1.0-SNAPSHOT-jar-with-dependencies.jar | ||
