The *Containers *pane of the Applications module enables you to manage Docker containers for deployed applications in your marketplace catalogs.

A container is a standardized unit of software. When you install an application from a marketplace, at least one container for the installed application appears on the *Containers *pane. You may also deploy a containerized Docker application that is not in any marketplace catalog by running a custom Docker run command.

All applications in marketplace catalogs run within [Docker containers](https://www.docker.com/resources/what-container). Each application runs its own dedicated container to ensure isolation. The Docker containers themselves run on Docker Engine, which is located on the Litmus Edge instance. Hence, if the Litmus Edge instance becomes unavailable, so will all the running containers.

A Docker container is a portable image that is lightweight, standalone, and executable. It includes everything needed to run an application (code, runtime, system tools, system libraries, and settings). See [Overview of 'docker run'](docId\:wnIfi0Bu4O7emqmndIw5D) to learn more about `docker run` commands. 

Each installed application runs at least one container, and can run multiple containers depending on the configuration.

**Note:** The **Run **button in the *Containers* pane can only be used for `docker run` commands. Other commands, including any other `docker` commands, cannot be used.

On the *Container *pane, each container's state is color-coded. A running container displays green, a paused container displays orange, and an exited container displays black.

You need to have a Docker registry to add an application to a marketplace or to create a new marketplace. The Docker registry and credential information are available through Litmus (the edge device provider). These registries provide access so that you can control and manage applications you choose to deploy in the marketplace.
