Fetch what's new from AWS and send out notifications on social sites.
go-aws-news can be executed as an application that sends out notifications to social sites like
Discord. To configure providers, modify the config.yaml file to enable a
provider.
go-aws-news is designed to be run on a schedule, once a day (displaying the previous day's AWS
News). See the install options for examples on how to install and run.
Currently supported providers:
The simplest way to run go-aws-news is via crontab.
Type crontab -e on Mac or Linux and add a line:
# Binary
0 2 * * * /path/to/go-aws-news-binary
# Docker
0 14 * * * docker run -d --rm --name aws-news \
-v your_config.yaml:/config.yaml \
circa10a/go-aws-newsThe above example will execute
go-aws-newsat2PM UTC(8AM CST) each day.
go-aws-news can be run as a CronJob in a Kubernetes cluster.
Example cronjob.yaml:
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: go-aws-news
spec:
schedule: "0 14 * * *"
jobTemplate:
spec:
template:

containers:
- name: go-aws-news
image: circa10a/go-aws-news
volumeMounts:
- name: config
mountPath: /config.yaml
subPath: config.yaml
volumes:
- name: config
configMap:
name: awsnews-config
restartPolicy: OnFailureThe ConfigMap can be created from the config.yaml file itself:
kubectl create configmap awsnews-config --from-file=config.yamlTo apply the cronjob.yaml example above:
kubectl apply -f cronjob.yaml-
Setup provider config in AWS SSM Parameter Store:
aws ssm put-parameter --type SecureString --name go-aws-news-config --value "$(cat config.yaml)"Note: Overriding the name
go-aws-news-configwill require an environment variable on the lambda function:GO_AWS_NEWS_CONFIG_NAME. -
Create the Lambda execution role and add permissions:
aws iam create-role --role-name go-aws-news-lambda-ex --assume-role-policy-document '{"Version": "2012-10-17","Statement": [{ "Effect": "Allow", "Principal": {"Service": "lambda.amazonaws.com"}, "Action": "sts:AssumeRole"}]}' aws iam attach-role-policy --role-name go-aws-news-lambda-ex --policy-arn arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole aws iam attach-role-policy --role-name go-aws-news-lambda-ex --policy-arn arn:aws:iam::aws:policy/AmazonSSMReadOnlyAccess -
Create the lambda function:
make lambda-package aws lambda create-function --function-name go-aws-news --zip-file fileb://bin/lambda.zip --runtime go1.x --handler awsnews \ --role $(aws iam get-role --role-name go-aws-news-lambda-ex --query Role.Arn --output text) -
Create a schedule for the lambda:
aws events put-rule --schedule-expression "cron(0 14 * * ? *)" --name go-aws-news-cron LAMBDA_ARN=$(aws lambda get-function --function-name go-aws-news --query Configuration.FunctionArn) aws events put-targets --rule go-aws-news-cron --targets "Id"="1","Arn"=$LAMBDA_ARN
-
Allow the lambda function to be invoked by the schedule rule:
EVENT_ARN=$(aws events describe-rule --name go-aws-news-cron --query Arn --output text) aws lambda add-permission --function-name go-aws-news --statement-id eventbridge-cron \ --action 'lambda:InvokeFunction' --principal events.amazonaws.com --source-arn $EVENT_ARN
go-aws-news can be installed as a module for use in other Go applications:
go get -u "github.com/circa10a/go-aws-news/news"Methods return a slice of structs which include the announcement title, a link, and the date it was posted as well an error. This allows you to manipulate the data in whichever way you please, or simply use Print() to print a nice ASCII table to the console.
package main
import (
awsnews "github.com/circa10a/go-aws-news/news"
)
func main() {
news, err := awsnews.Today()
if err != nil {
// Handle error
}
news.Print()
}news, _ := awsnews.Yesterday()news, _ := awsnews.ThisMonth()// Custom timeframe(June 2019)
news, err := awsnews.Fetch(2019, 06)// Custom timeframe(2017)
news, err := awsnews.FetchYear(2017)news, _ := awsnews.ThisMonth()
news.Print()
// Console output

fmt.Printf("Link: %v\n", v.Link)
fmt.Printf("Date: %v\n", v.PostDate)
}news, _ := awsnews.ThisMonth()
