Scale your PM4Py-WS containers!

Scale your containers with Docker compose and Docker swarm

Aside from the classic all-in-memory deployment, that is available in the docker image javert899/pm4pyws:latest and could be used with the following instructions:

docker pull javert899/pm4pyws:latest

docker run -d -p 80:80 javert899/pm4pyws:latest


We included the possibility to scalably deploy several containers of PM4Py-WS, sharing the same logs and the same database, and not acting in-memory to support a large number of requests and logs.

The scalable deployment is based on the javert899/pm4pyws:multiNode image. It can be deployed using Docker compose and Docker swarm, moreover it can be used in a Minikube/Kubernetes installation.

Steps to use Docker compose to scale the number of containers:

  1. Pull the image using docker pull javert899/pm4pyws:multiNode
  2. On Linux, copy the files directory into /opt/files (this is the default path specified in docker compose, if not change it to a path that you like)
  3. Reach the folder containing the docker-compose.yml file (in the default setting, it is the multinode_compose directory).
  4. The compose file is thought for the exposition of at most 4 containers, hence the listening (on the same machine) of the ports 80-83 and their re-direction to the port 80 of UWSGI is configured. If you would like to deploy more containers, please change the number accordingly.
  5. Use the following command to start the three containers: docker-compose up –scale pm4pyws=3

The docker-compose.yml file can be used also to deploy the services into a Docker swarm (the Docker’s default orchestration). Follow the tutorial:
