CWLOGS - Cloud Watch Logs Downloader

Tiny utility for downloading log files from Amazon Cloud Watch.

Installation using Docker

docker build -t cwlogs .

Usage with default AWS credentials

docker build -t cwlogs .
docker run --rm -v $(pwd):/logs -e "HOME=/home" -v $HOME/.aws:/home/.aws cwlogs --group LOGS_GROUP --stream LOGS_STREAM

Usage with custom AWS profiles

AWS_ACCESS_KEY_ID=$(aws --profile default configure get aws_access_key_id)
AWS_SECRET_ACCESS_KEY=$(aws --profile default configure get aws_secret_access_key)
docker run --rm -v $(pwd):/logs -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY cwlogs --group LOGS_GROUP --stream LOGS_STREAM

Native binary usage

go install
cwlogs --group group_name --stream stream_name

AWS Config

Be sure you have ~/.aws/credentials file with you AWS credentials:

[default]
aws_access_key_id = YOUR_KEY_ID
aws_secret_access_key = YOUR_SECRET

P.S. CWLOGS will download logs until an empty results returned from AWS. It means you shouldn't use it for logs that someone still writes to it.
