Using Docker with asyncua on arm!

[ayham291]

I encountered an issue with asyncua when installing in a Docker environment on arm devices (Raspberrypi 4/5).

The issue is not exactly related to asyncua, but rather cryptography because it gets compiled in rust.

The issue occurs on debian images. So here I provided a basic Dockerfile, which should work with all versions from cryptography.

Reasons:

• you need to have rust toolchain installed and not only cargo
• you need to have libssl-dev and libeffi-dev installed
• when rust compiles cryptography it looks for the openssl libraries with pkg-config so you need it too

FROM debian:bookworm-slim

RUN apt update
RUN apt install curl python3.11 python3-pip libffi-dev libssl-dev pkg-config -y
RUN curl -L sh.rustup.rs | sh -s -- -y

RUN PATH="/root/.cargo/bin:${PATH}" pip install asyncua --break-system-packages

related issues:

• python OPCUA or opcua-asyncio package installation failed in Linux ARM32V7  #1283

here is what it would like if you only install cargo:
