EC2 Worker

Config

The aws-cli is pre-installed on the ec2 instance we just need to add credentials. SSH onto the box and run:

aws configure

and follow the prompts.

User-Data

Add this to the EC2 user-data. With this in place the Go app (or any script) will run every time the EC2 instance is booted. More on this here (opens new window).

Build + Upload

./_script/build.sh

# upload
scp -i ~/.ssh/<my_keys> functions/canada/bin/main ec2-user@<some_ip_address>:/home/ec2-user

# upload .env if needed
scp -i ~/.ssh/<my_keys> .env ec2-user@<some_ip_address>:/home/ec2-user

# move files.
# ssh onto the box.
sudo mv main /bin/main
sudo mv .env /.env

This whole process could probably be cleaned up / automated with Puppet or Jenkins or something...
