OverOps Docker Demos

OverOps (OO) supports three deployment models (SaaS, Hybrid, On-Prem) and works well with both containers and traditional servers or virtual machines. The following examples demonstrate how to get up and running quickly using Docker for each deployment model using a variety of configurations and techniques. While a majority of these examples use Docker Compose to define multiple services, the underlying Docker images could be used alone or with a variety of other container management or orchestration tools.

Tips and Tricks

Cleaning up Docker

You can easily delete previously download images for these examples with the following command:

docker images -a | grep "timveil" | awk '{print $3}' | xargs docker rmi -f

or, for a complete system prune (this is what I usually do):

docker system prune -a -f --volumes --filter "label=maintainer=tjveil@gmail.com"

Remove all stopped containers:

docker ps -aq --no-trunc -f status=exited | xargs docker rm

Remove all dangling images:

docker images -q --filter dangling=true | xargs docker rmi
