Check runtime dependencies
- iptables version 1.4 or later
- Git version 1.7 or later
- procps (or similar provider of a “ps” executable)
- XZ Utils 4.9 or later
- a properly mounted cgroupfs hierarchy (having a single, all-encompassing “cgroup” mount point is not sufficient)
Check kernel dependencies
Docker in daemon mode has specific kernel requirements. For details, check your distribution in Installation.A 3.10 Linux kernel is the minimum requirement for Docker. Kernels older than 3.10 lack some of the features required to run Docker containers. These older versions are known to have bugs which cause data loss and frequently panic under certain conditions.
The latest minor version (3.x.y) of the 3.10 (or a newer maintained version) Linux kernel is recommended. Keeping the kernel up to date with the latest minor version will ensure critical kernel bugs get fixed.
Warning: Installing custom kernels and kernel packages is probably not supported by your Linux distribution’s vendor. Please make sure to ask your vendor about Docker support first before attempting to install custom kernels on your distribution.
Warning: Installing a newer kernel might not be enough for some distributions which provide packages which are too old or incompatible with newer kernels.Note that Docker also has a client mode, which can run on virtually any Linux kernel (it even builds on OS X!).
