Integrating C++ frontend enhancements in a CI/CD pipeline with Docker and GitHub Actions
Hey everyone, I'm running into an issue that's driving me crazy. After trying multiple solutions online, I still can't figure this out. I'm stuck on something that should probably be simple... Currently developing a CI/CD pipeline for our project, which heavily relies on a C++ application that interfaces with a frontend built using React. The goal is to ensure that every change pushed to our GitHub repository triggers a build that runs our unit tests and deploys the updated binaries. I've been using Docker to create a consistent environment for both testing and deployment. Here’s a snippet of my Dockerfile: ```Dockerfile FROM gcc:11 WORKDIR /app COPY . . RUN g++ -o my_app main.cpp ``` The challenge begins when the CI/CD pipeline fails during the `RUN g++` step. The error messages vary wildly but often relate to missing headers or libraries, leading me to believe there might be a misconfiguration in my Docker setup. I’ve checked that the required dependencies are indeed included in the Docker image, yet the C++ libraries aren't found. In my GitHub Actions workflow, I’m using the following setup: ```yaml name: CI on: [push] jobs: build: runs-on: ubuntu-latest steps: - name: Checkout code uses: actions/checkout@v2 - name: Set up Docker run: docker build -t my_app . - name: Run tests run: docker run my_app ./tests ``` This setup should theoretically allow me to run my C++ application tests after building the Docker image. However, I keep running into issues where the test binaries cannot be found, or the tests themselves fail to execute due to execution context issues. Last week, I added specific libraries like Boost and found that specifying the installation directly in the Dockerfile helped resolve some header issues, but the far more complex dependencies remain a challenge. I’ve tried using multi-stage builds as well, which seemed like a good idea to keep the final image small. However, it also introduced more complexity in tracking dependencies. Does anyone have insights or best practices for setting up a CI/CD pipeline that effectively integrates a C++ application with Docker in a GitHub Actions workflow? Any advice on resolving these dependency issues or simplifying the build process would be greatly appreciated. My development environment is Linux. What's the best practice here? I'm using C++ LTS in this project. What's the correct way to implement this? I'm working with C++ in a Docker container on Linux. Any pointers in the right direction? Could someone point me to the right documentation?
