Docker is easy to manage
Automation integration with the docker engine
Need
I wanted to host and tests some apps before publishing/use it on internet. The physical server hosting are light, small and silent. The solution must not consume a lot of ressources.
The client wants to rely on this service so emails can go through and alert teams on time. The service must be available or alert people in case of failure.
