| ## What is the image storage driver Pouch uses | ||
|
|
||
| PouchContainer uses overlay2 as its default image storage driver. To be more detailed, containerd 1.0.0+ begins to make use of overlay2 to store images. While currently containerd is a base component in PouchContainer. For Linux mainline kernel, only kernel version 4.0 starts to support overlay2. So, in theory, PouchContainer can only run on Linux distribution which are based on kernel 4.0+. However, RedHat series, like CentOS 7.2+ and so on, supports overlay2 stably since kernel version 3.10.327. For more information on RedHat, please refer to [Red Hat Enterprise Linux Release Dates](https://access.redhat.com/articles/3078#RHEL7). |
