Docker Examples

For testing and development purposes there are two examples using the PKCS11 driver with Nginx and Apache.

They require each a certificate built with the container/<server>/generate.sh.

They can be built with:

# Building the images 
docker build -t nginx-testing -f container/nginx/Dockerfile .
docker build -t apache-testing -f container/apache/Dockerfile .

Assuming that a NetHSM is runnig on localhost:8443, they can then be run with :

docker run --net=host nginx-testing:latest
docker run --net=host apache-testing:latest

The NetHSM is expected to have be provisionned with the following configuration:

nitropy nethsm --host localhost:8443 --no-verify-tls provision -u 0123456789 -a Administrator
nitropy nethsm --host localhost:8443 --no-verify-tls add-user -n Operator -u operator -p opPassphrase -r Operator

Building

Required are gcc and a working Rust toolchain of at least version (MSRV) 1.70.

cargo build --release

The dynamic library will be in ${CARGO_TARGET_DIR:-target}/release/libnethsm_pkcs11.so.

Alpine Linux

You need to install musl-dev and gcc:

apk add musl-dev gcc

To build on Alpine Linux you will need to add the C argument target-feature=-crt-static:

RUSTFLAGS="-C target-feature=-crt-static" cargo build --release
