Why this name? Well, it seemed right at the time, and all logging related utilities seem to be named after the logging industry.
To use the latest packaged version of bushwack, simply launch the stack using the latest packaged code.
If you are wanting to host and maintain your own packaged code you can package it yourself and upload it to an S3 bucket that you own.
First, make sure you have the binary built.
GOOS=linux go build -o main main.go
Then, package it up using the specified input template file and your specified S3 Bucket.
aws cloudformation package \
--template-file template.yml \
--output-template-file cfn-output.yaml \
--s3-bucket <your-bucket>
Then simply deploy using the cloudformation deploy command.
aws cloudformation deploy \
--template-file ./cfn-output.yaml \
--stack-name <stack-name> \
--parameter-overrides EsUrl=<elasticsearch-url> \
--capabilities CAPABILITY_IAM
After using an S3 input in logstash it seemed be to having constant issues attempting to ingest logs from our S3 bucket we use for access logs. Additionality we didn't really want to shuffle around the data or rename all keys to satisfy an exclude pattern within logstash.
We realized lambda could accomplish the large task of indexing all logs into ElasticSearch in a near real time fashion (we want to index the logs as close to when AWS writes it into the bucket as possible).
- We currently don't have any feature to retry indexing a log file if any type of failure happens.
- We are only parsing ALB logs, not legacy ELB logs.
Ensure you have dep installed.
go get -d github.com/CreditCardsCom/bushwackdep ensurego test bushwack/
This uses the new AWS provided go lambda toolkit. Building the lambda per aws-lambda-go documentation:
GOOS=linux go build -o main main.go
zip main.zip mainAt this point the project only supports being run on AWS Lambda. The following environment variables are needed to run.
Configures the Elasticsearch host that will be used to index the log output.
