The following configuration should be generated automatically after the previous two steps: Before each run, code will be rsync-ed to the container at a temporary location. Go to Settings/Preferences | Build, Execution, Deployment | CMake, add a container CMake profile:Ĭheck the file mapping settings in Clion. The completed configurations should be similar to the following:Ĭonfigure the container CMake settings in CLion.

Go to Settings/Preferences | Build, Execution, Deployment | Toolchains, configure the container as a remote host. CLion will not use this mapped directory.Ĭonfigure the container toolchain in Clion. The folder where docker-compose.yml locates will be the mapped to /home/debugger/code within the container. Clion will automatically run/test/debug via an ssh connection. Import the project into CLion using the provided CMakeLists.txt.Īfter this step, the container is running with an ssh server daemon. If you have any problem, please refer to the official tutorial before opening an issue. To debug the example, follow the following steps. The latest Docker CE installation would be sufficient. On the host machine of your container (which can be the development machine), On your development machine, you must have a CLion IDE (2018.3 or above) installed, To any arbitrary number in docker-compose.yml. Machine, the container 22 port is mapped to host 7776 port. To avoid trouble when the container is launched on the development The container has a long running ssh server process, such that the container can Then, we launch a gdbserver to allow remote debugging outside of the container.Ĭlion supports remote debugging feature since 2018.3. The container can be launched on your development machine, or on a remote server.Īll application code, as well as its dependencies, will be installed, compiled, and ran within the container.Some packages cannot be easily installed on OS X.

Developers are free from installing dependencies on their development.

It allows a consistent environment for both development and deployment.

This repository provides a minimal C++ project setup and the Dockerfile thatĪllows developers to debug code in a Docker container using JetBrain Clion IDE.ĭebugging in a container has many benefits, especially if you are developing Update December 2018: this repository has been updated after the Clion 2018.3 release, which adds native remote debugging support.Ĭheck out the official guide It makes a debugger's life much easier.
