## Container Platforms
This module looks for container platforms running on the target and then lists any currently running containers for each platform found. The currently supported container platforms are:
1. Docker
2. LXC
3. RKT
## Verification Steps
1. Start msfconsole
2. Get a session via exploit of your choice
3. Load the module `use post/linux/gather/enum_containers`
4. Set the session `set session 1`
5. run the module `run`
6. You should get feedback if any container platforms are runnable by the current user and if there are any active containers running on them
## Options
**SESSION**
Which session to use, which can be viewed with `sessions -l`
**CMD**
Optional shell command to run on each running container
## Scenarios
Scenario 1: Docker is installed with 4 running containers
```
msf5 post(linux/gather/enum_containers) > set session 4
session => 4
