## What is ALM-agent?  <a href="#what-is-alm-agent" id="what-is-alm-agent"></a>

The ALM-agent is software for Mobingi ALM. ALM-agent is the primary component of container management.

ALM-agent runs on instances, manages Docker containers and deploys code to instances on behalf of you.

ALM-agent works with [ALM Template](https://docs.mobingi.com/mobingi-alm/alm-template/what-is-alm-template). When you run the ALM-agent, the agent on the instance processes the ALM Template and configures the instance as specified.
