containerd is built with OCI support and with support for advanced features provided by [runc](https://github.com/opencontainers/runc).
We depend on a specific `runc` version when dealing with advanced features. You should have a specific runc build for development. The current supported runc commit is:
RUNC_COMMIT = 7f24b40cc5423969b4554ef04ba0b00e2b4ba010
For more information on how to clone and build runc see the runc Building [documentation](https://github.com/opencontainers/runc#building).
Note: before building you may need to install additional support, which will vary by platform. For example, you may need to install `libseccomp` and `libapparmor` e.g. `libseccomp-dev` and `libapparmor-dev` for Ubuntu.
## building
From within your `opencontainers/runc` repository run:
### apparmor
```bash
make BUILDTAGS='seccomp apparmor' && sudo make install
```
### selinux
```bash
make BUILDTAGS='seccomp selinux' && sudo make install
```
After an official runc release we will start pinning containerd support to a specific version but various development and testing features may require a newer runc version than the latest release. If you encounter any runtime errors, please make sure your runc is in sync with the commit/tag provided in this document.
