Fluentd image to send Kubernetes logs to CloudWatch

Gratefully forked from https://github.com/callstats-io/fluentd-kubernetes-cloudwatch

The changes are to make the deployment more automated and configurable.

Deployment

1. Create AWS IAM user which has permission to store logs to CloudWatch

2. Set environment variables for the AWS IAM user including region

export AWS_ACCESS_KEY_ID=<your key>
export AWS_SECRET_ACCESS_KEY=<your secret>
export AWS_DEFAULT_REGION=<your region>

3. Optionally set other environment variable to change resource names or labels

• NAMESPACE defaults to 'kube-system'
• APP_NAME defaults to 'fluentd-cloudwatch'
• SECRET_NAME,CONFIG_NAME default to APP_NAME
• ENV_NAME defaults to 'system'
• CW_LOG_GROUP defaults to 'kubernetes-cluster'

4. Run Deploy.sh to create the Secret, ConfigMap, and DaemonSet

5. Run Display.sh to check everything is running

Removal

1. If you set custom values for the namespace or resource name environment variables, ensure they are still set to your values (NAMESPACE,APP_NAME,SECRET_NAME,CONFIG_NAME)

2. Run Delete.sh

3. Run Display.sh to check nothing is left
