Creating block diagrams from docker-compose files

A docker-compose file contains the definition of all the services that needs to run in harmony to successfully deploy an app stack.

When services and their interactions are defined clearly in a compose file manually charting a block diagram to list those services and their interaction is redundant, isn't it ? that was the thought I had when I needed to chart a block diagram for documenting my architecture.

A quick search using "tool to convert a docker compose file to a block diagram" yielded this awesome repo https://github.com/pmsipilot/docker-compose-viz

The code in this repo will help us to chart a block diagram from a docker compose file.

Lets create one!

• Sample docker-compose of a simple SaaS stack
  

• Command to execute

   docker run --rm -it \ --name dcv \ -v /home/user/blog:/input pmsipilot/docker-compose-viz \ render -m image \ --force docker-compose.yml \ --output-file=topology.png \ --no-volumes \ --no-ports \ --no-networks 

• Ouptput

• Command - With port numbers

 docker run --rm -it \ --name dcv \ -v /home/user/blog:/input pmsipilot/docker-compose-viz \ render -m image \ --force docker-compose.yml \ --output-file=topology.png \ --no-volumes \ --no-networks 

• Ouptput - with ports
  

• Command - With volumes

 docker run --rm -it \ --name dcv \ -v /home/user/blog:/input pmsipilot/docker-compose-viz \ render -m image \ --force docker-compose.yml \ --output-file=topology.png \ --no-ports \ --no-networks 

• Ouptput - with volumes
