SMS-Worker

Description

Grab messages from an AWS SQS queue, determine the action to take, generate message(s) and send them to Twilio.

Requirements

• Docker

OR

• Golang 1.10
• A directory for Go development configured in $GOPATH, see below
• Godep
• go-bindata
• A .env file with the following items...
  • The first three items in the example .env file below (AWS credentials and environment) MUST be in that order at the top of the file.

Development System Setup

To set your system up to develop this application...

1. Make sure you have everything from the requirements section
2. If you do not have GOPATH configured, set one up pointing to a place you'll develop from. For example, mkdir ~/dev/go and then export GOPATH=~/dev/go
3. Use godeps to get the dependencies and this repository: godep get github.com/votinginfoproject/sms-worker
4. This repo should now be at $GOPATH/src/github.com/votinginfoproject/sms-worker, cd into it.
5. If you're using RBEnv to manage Ruby versions, make sure you have 2.1.2 installed and drop a .ruby-version file in this directory with the contents 2.1.2 to make sure you use the right version.
6. Run bundle

If you're not on Linux and AMD64, you'll need to compile Go for Linux since the deploy artifact needs to be this as that's the kind of server it is installed on in AWS.

1. Figure out where your Go install is: which go (/usr/local/bin/go if you installed with homebrew)
2. Find the go src path which should be nearby (/usr/local/Cellar/go/1.4.2/libexec/src if installed with homebrew)
3. Make go for linux/AMD64 by running GOOS=linux GOARCH=amd64 ./make.bash --no-clean

Docker Development System Setup

It is potentially easier to develop with Docker.

To compile and run the project, the typical docker build and run commands will work. When running, you will need to have the environment variables above set, because the docker version does not use the .env file.

With the environment variables set, the commands are:

$ docker build -t sms-worker .
$ docker run sms-worker

Commands

Run Tests

godep go test ./...

To run the tests in docker:

• docker build -t sms-worker . to build the Docker image
• docker run -ti --env-file .env sms-worker /bin/bash to start the container with an interactive terminal
• godep go test ./... to run the tests.

Generate Go Data File From YAML

go-bindata -prefix "data" -pkg "data" -o data/data.go data/raw

• Generates a new data/data.go file

Deploy

See the sms-compose repository for deployment instructions.
