Often, when installing deb packages in your Dockerfile, some packages will install tzdata as a dependency. RUN apt update & apt -y install build-essential make & rm -rf /var/lib/apt/lists/*ĬMD Posted by Uli Köhler in Build systems, C/C++, Container, Docker Here’s the complete Dockerfile used to generate ulikoehler/ubuntu-gcc-make: FROM ubuntu:18.04 You can use any command here, even no command is possible (in which case the container’s default command will be used – in case of ulikoehler/ubuntu-gcc-make that is CMD )

make: This is the command we’ll run in the container.

It’s nothing more than an ubuntu:18.04 base image with build-essentials and make installed and WORKDIR set to /app

ulikoehler/ubuntu-gcc-make: This is the image we’re using for that example.

Also, this means that our command will only finish when the container has finished executing. keypressed are passed down to the command you are running.

-it runs the container in interactive mode, i.e.

Since the Dockerfile used to build the container contains the WORKDIR /app directive, whatever command we run in the container will by default be executed in the /app directory – and therefore in the current local directory on the host.

-v $PWD:/app: Mount the current directory ( $PWD) on /app in the container.

Also see How to run docker container as current user & group -user $(id -u):$(id -g): This makes the docker container run with the current user’s ID and the current user’s group – both for preventing the compiler to create output files as root and to safeguard against some IT security risks.docker run: Create a new docker container and run a command in it.How can we compile this simple project without installing a compiler and GNU make on the local computer (no cheating by using build servers allowed)?Īctually it’s rather simple: docker run -user $(id -u):$(id -g) -v $PWD:/app -it ulikoehler/ubuntu-gcc-make make

Take the obligatory Hello World in C++: // main.cpp My approach is to dockerize not neccessarily the application itself but the build system, encapsulating both the specific compiler version and the system around it plus all required system-level libraries in a Docker image. Many C/C++ programmers and project managers know the pain of creating a reproducible build environment for all developers: Works for me is a common meme not without a reason. Note: Based on this post I have published buildock on GitHub.
