starting using gsc with python example fails

[polestar1988]

I have installed gramine and SGX driver and DCAP and PSW on my server which is sgx enables, Now I want to build a docker image using gsc, how could I start? I have created the docker image also cloned gsc. Is there something else that I have to do? How should I create manifest file? could some one explain it step by step?
Besides, I just started a test :

meson --version
1.3.1

docker pull python:bullseye
cd gsc
cp config.yaml.template config.yaml
openssl genrsa -3 -out enclave-key.pem 3072
./gsc build --insecure-args python:bullseye --build-arg http_proxy="${http_proxy}" --build-arg https_proxy="${https_proxy}" --build-arg no_proxy="${no_proxy}" test/generic.manifest
and I get :

You seem to hit this error: #1501

This means that you're not using the latest Gramine version (inside GSC). Can you show the contents of config.yaml in the GSC directory?

You should use Gramine's v1.6 version or master.

[polestar1988]

config.yml:

Specify the OS distro that is used to build Gramine, i.e., the distro from where the Gramine build
# gets all tools and dependencies from. This distro should match the distro underlying the
# application's Docker image; otherwise the results may be unpredictable.
#
# Currently supported distros are:
# - ubuntu:20.04, ubuntu:21.04
# - debian:10, debian:11
# - centos:8
Distro: "ubuntu:20.04"

# If the image has a specific registry, define it here.
# Empty by default; example value: "registry.access.redhat.com/ubi8".
Registry: ""

# If you're using your own fork and branch of Gramine, specify the GitHub link and the branch name
# below; typically, you want to keep the default values though.
#
# It is also possible to specify the prebuilt Gramine Docker image (that was built previously via
# the `gsc build-gramine` command). For this, remove Repository and Branch and instead write:
#   Image:      "<prebuilt Gramine Docker image>"
#
# GSC releases are guaranteed to work with corresponding Gramine releases (and GSC `master`
# branch is guaranteed to work with current Gramine `master` branch).
Gramine:
    Repository: "https://github.com/gramineproject/gramine.git"
    Branch:     "v1.5"

# Specify the Intel SGX driver installed on your machine (more specifically, on the machine where
# the graminized Docker container will run); there are several variants of the SGX driver:
#
#   - upstream (in-kernel) driver: use empty values like below
#         Repository: ""
#         Branch:     ""
#
#   - DCAP out-of-tree driver: same as above, use empty values
#         Repository: ""
#         Branch:     ""
#
#   - legacy out-of-tree driver: use something like the below values, but adjust the branch name
#         Repository: "https://github.com/01org/linux-sgx-driver.git"
#         Branch:     "sgx_driver_1.9"
#
SGXDriver:
    Repository: ""
    Branch:     ""

I used Gramine's master

[polestar1988]

@dimakuv I already have used --insecure-args when building gsc image , but I have to pass some arguments as you see in docker compose (password and token) to the application , when I use normal image in docker compose it is working but when I use gsc image I get error from my application regards to empty password. Do you know how could I solve it?

[dimakuv]

@polestar1988 I still don't understand what is your original Docker image (that you supply to gsc build).

It looks like your original Docker image contains the ENTRYPOINT which is the Docker Compose invocation? Are you trying to use Docker Compose inside the Gramine SGX enclave? Is this your purpose?

[polestar1988]

@dimakuv okay ,The entry Point in the Dockerfile is my application (connectorApp) ,
I moved on and want to use docker run instead of docker compose ,
this is the manifest:

sgx.enclave_size = "4G"
sgx.max_threads = 30
sgx.remote_attestation = "dcap"

sgx.trusted_files = [
  "file:/gramine/app_files/entrypoint.manifest",  # unused entry, only to test merging of manifests
  "file:ConnectorConfig.properties",
]
sgx.allowed_files = [
 "file:data/certs/connector-req.pem", 
 "file:data/certs/connector-key.pem",
 "file:data/certs/connector-cert.pem",
]

inst it that allowed_files are for both creating and reading from files , but when I execute command docker run when the application wants to create this files I get error:

docker run --name sgxconnector3 -it --device=/dev/sgx_enclave -v /var/run/aesmd/aesm.socket:/var/run/aesmd/aesm.socket  -p 50052:50052 -v /home/sgx_user/connector/ConnectorConfig.properties:/app/ConnectorConfig.properties gsc-project/connector -p test -t <token>

Gramine is starting. Parsing TOML manifest file, this may take some time...
-----------------------------------------------------------------------------------------------------------------------
Gramine detected the following insecure configurations:

  - loader.insecure__use_cmdline_argv = true   (forwarding command-line args from untrusted host to the app)
  - sgx.allowed_files = [ ... ]                (some files are passed through from untrusted host without verification)

Gramine will continue application execution, but this configuration must not be used in production!
-----------------------------------------------------------------------------------------------------------------------

Emulating a raw syscall instruction. This degrades performance, consider patching your application to use Gramine syscall API.

2024/01/24 13:26:19 ERROR Failed to initialize certificate Manager. Config=ConnectorConfig.properties Error="Error encrypting private key: open data/certs/connector-key.pem: permission denied"

the data/certs/connector-key.pem should create by the application ,
in docker file path data/certs/ has already created :

...
WORKDIR /app

RUN mkdir -p data/certs
....

[dimakuv]

@polestar1988 I think the problem is that you have relative paths in sgx.allowed_files.

Given that you have WORKDIR /app, why not specify absolute paths? This way you won't need to care about the mismatch of the starting directory. Just try this:

sgx.allowed_files = [
 "file:/app/data/certs/connector-req.pem", 
 "file:/app/data/certs/connector-key.pem",
 "file:/app/data/certs/connector-cert.pem",
]

[polestar1988]

@dimakuv oh yes that's right.
