surf-archiver

The surf-archiver tool consists of two components:

1. a CLI tool
2. a remote client which can execute CLI installed on a remote machine

The CLI tool copies daily data from S3 supported storage, bundling it into a per experiment per day tar archives. Once completed it emits a message via RabbitMQ. The intended use case is for the CLI tool to installed on the Surf Data Archive and remotely triggered daily.

The tool copies data based on the S3 key. It is assumed that the keys have the following structure:

<SRC BUCKET>/<images|videos>/<EXPERIMENT-ID>/YYYYMMDD/*.tar

The resulting archive will be created at:

<DATA DIR>/<images|videos>/<EXPERIMENT-ID>/YYYY-MM-DD.tar

Installation of the CLI tool

The CLI tool can be installed via pipx.

In order to run the tool needs some configuration. It can be configured by via a yaml file:

bucket:             # S3 bucket data is pulled from
target_dir:         # Target directory data is stored in       
connction_url:      # RabbitMQ connection url
exchange_name:      # RabbitMQ Exchange name
log_file:           # log file path

By default the tool will look for this configuration in the ${HOME}/.surf-archiver. The tool will additionally look for these parameters in the shell environment. If they are defined here, they need to be prefixed by surf_archiver_.

In addition to the above, the following environment variables need to be set in order to connect to S3.
