EasyLink

EasyLink is a framework that allows users to build and run highly configurable entity resolution (ER) pipelines.

Installation

• Clone and install this repo

$ cd <path/to/repositories/>
$ git clone git@github.com:ihmeuw/easylink.git
$ # OR `git clone https://github.com/ihmeuw/easylink.git`
$ cd easylink
$ pip install .

Running a pipeline

$ easylink run <PIPELINE-SPECIFICATION>
$ # e.g. `easylink run ~/repos/easylink/src/easylink/pipelines/pipeline.yaml`

Requirements

TBD

Creating a docker image to be shared

Docker image binaries can be built from a Dockerfile. For example, to create a compressed image .tar.gz file:

$ cd <PATH-TO-DOCKERFILE-PARENT-DIRECTORY>
$ # build the image
$ sudo docker build -t easylink:<IMAGE-NAME> .
$ # save as compressed tarball
$ sudo docker save easylink:<IMAGE-NAME> | gzip > <IMAGE-NAME>.tar.gz
$ # remove the image
$ sudo docker rmi easylink:<IMAGE-NAME>

You can use the -f option to build a dockerfile from a different location (including a different filename than 'Dockerfile'):

sudo docker build -t easylink:<IMAGE-NAME> <PATH-TO-DOCKERFILE>

You should now have an image file named <IMAGE-NAME>.tar.gz alongside the Dockerfile which can be used to spin up the container.

Note that it may be occasionally required to clean up unused data to make room for building images: sudo docker system prune.

Creating a singularity image to be shared

Singularity image files can be created from a Singularity file. For example:

$ cd <PATH-TO-SINGULARITY-FILE-PARENT-DIRECTORY>
$ # build the image
$ singularity build --force <IMAGE-NAME>.sif Singularity

Alternatively, a Docker binary can be converted to a Singularity image file:

$ singularity build --force <IMAGE-NAME>.sif docker-archive://$(pwd)/<IMAGE-NAME>.tar.gz
