# Quick Start: rune on Occlum
|
|
|
|
[Rune](https://github.com/alibaba/inclavare-containers) is a set of tools for running trusted applications in containers with the hardware-assisted enclave technology.
|
|
|
|
## Hardware requirements
|
|
- Install [Intel SGX driver for Linux](https://github.com/intel/linux-sgx-driver#build-and-install-the-intelr-sgx-driver), required by Intel SGX SDK && PSW.
|
|
- Install [enable_rdfsbase kernel module](https://github.com/occlum/enable_rdfsbase#how-to-build), allowing to use `rdfsbase` -family instructions in Occlum.
|
|
|
|

|
|
|
|
## Build and install rune
|
|
`rune` is a CLI tool for spawning and running enclaves in containers according to the OCI specification.
|
|
|
|
Please refer to [this guide](https://github.com/alibaba/inclavare-containers#rune) to build `rune` from scratch.
|
|
|
|
---
|
|
|
|
## Build Occlum application bundle
|
|
### Download Occlum sdk image
|
|
``` shell
|
|
yum install -y libseccomp-devel
|
|
mkdir "$HOME/rune_workdir"
|
|
docker pull occlum/occlum:0.12.0-centos7.2
|
|
docker run -it --device /dev/isgx \
|
|
-v $HOME/rune_workdir:/root/rune_workdir \
|
|
occlum/occlum:0.12.0-centos7.2
|
|
```
|
|
|
|
You can then build a hello world demo program or your product code using an [Occlum CentOS Docker image](https://hub.docker.com/r/occlum/occlum/tags).
|
|
|
|
[This guide](https://github.com/occlum/occlum#hello-occlum) can help you to create your first occlum build.
|
|
|
|
### Prepare the materials
|
|
After your Occlum build, execute the following commands in Occlum sdk container environment:
|
|
|
|
``` shell
|
|
cp -a .occlum /root/rune_workdir
|
|
cd /root/rune_workdir
|
|
mkdir lib
|
|
cp /usr/lib64/libseccomp.so.2 lib
|
|
cp /usr/lib64/libprotobuf.so.8 lib
|
|
cp /usr/lib64/libsgx_u*.so* lib
|
|
cp /usr/lib64/libsgx_enclave_common.so.1 lib
|
|
cp /usr/lib64/libsgx_launch.so.1 lib
|
|
```
|
|
|
|
### Build occlum application image
|
|
Now you can build your occlum application image in the `$HOME/rune_workdir` directory of your host system.
|
|
|
|
Type the following commands to create a `Dockerfile`:
|
|
``` Dockerfile
|
|
cat >Dockerfile <<EOF
|
|
FROM centos:7.2.1511
|
|
|
|
RUN mkdir -p /run/rune/.occlum
|
|
WORKDIR /run/rune
|
|
|
|
COPY lib /lib
|
|
COPY .occlum .occlum
|
|
|
|
RUN ln -sfn .occlum/build/lib/libocclum-pal.so liberpal-occlum.so
|
|
RUN ldconfig
|
|
|
|
ENTRYPOINT ["/bin/hello_world"]
|
|
EOF
|
|
```
|
|
|
|
and then build it with the command:
|
|
```shell
|
|
docker build . -t occlum-app
|
|
```
|
|
|
|
### Create bundle
|
|
In order to use `rune` you must have your container in the format of an OCI bundle. If you have Docker installed you can use its `export` method to acquire a root filesystem from an existing Docker container.
|
|
|
|
``` shell
|
|
# create the top most bundle directory
|
|
cd "$HOME/rune_workdir"
|
|
mkdir rune-container
|
|
cd rune-container
|
|
|
|
# create the rootfs directory
|
|
mkdir rootfs
|
|
|
|
# export occlum-app via Docker into the rootfs directory
|
|
docker export $(docker create occlum-app) | sudo tar -C rootfs -xvf -
|
|
```
|
|
|
|
After a root filesystem is populated you just generate a spec in the format of a config.json file inside your bundle. `rune` provides a spec command which is similar to `runc` to generate a template file that you are then able to edit.
|
|
|
|
``` shell
|
|
rune spec
|
|
```
|
|
|
|
To find features and documentation for fields in the spec please refer to the [specs](https://github.com/opencontainers/runtime-spec) repository.
|
|
|
|
In order to run the hello world demo program in Occlum with `rune`, you need to change the entrypoint from `sh` to `/bin/hello_world`
|
|
``` json
|
|
"process": {
|
|
"args": [
|
|
"/bin/hello_world"
|
|
],
|
|
}
|
|
```
|
|
|
|
and then configure enclave runtime as following:
|
|
``` json
|
|
"annotations": {
|
|
"enclave.type": "intelSgx",
|
|
"enclave.runtime.path": "/run/rune/liberpal-occlum.so",
|
|
"enclave.runtime.args": ".occlum"
|
|
}
|
|
```
|
|
|
|
---
|
|
|
|
## Run Occlum application
|
|
Assuming you have an OCI bundle from the previous step you can execute the container in this way.
|
|
|
|
``` shell
|
|
cd "$HOME/rune_workdir/rune-container"
|
|
sudo rune run rune-container
|
|
```
