Docker Kibana to S3 Backup

How to use

The container is configured via a set of environment variables:

• AWS_ACCESS_KEY: Get this from amazon IAM
• AWS_SECRET_ACCESS_KEY: Get this from amazon IAM, you should keep this a secret
• S3_BUCKET_URL: in most cases this should be s3://name-of-your-bucket/
• AWS_DEFAULT_REGION: The AWS region your bucket resides in
• CRON_SCHEDULE: Check out crontab.guru for some examples. Do not wrap this value in quotes
• BACKUP_NAME: A name to identify your backup among the other files in your bucket, it will be postfixed with the current timestamp (date and time)
• KIBANA_HOST: The host where the Kibana instance resides
• KIBANA_PORT: The port that Kibana listens on
• KIBANA_USER: A Kibana user with sufficient privileges to read any saved objects
• KIBANA_PASSWORD: The password for said user
• KIBANA_VERSION: The Kibana version string used in the kbn-version header, e.g. 7.2.0
• TZ: The timezone to be used inside the container

All environment variables prefixed with 'AWS_' are directly used by awscli that this image heavily relies on.
