This project runs the first example in C++ from the ØMQ guide located here. The Docker containers take care of all the install instructions needed to get up and running with C++ and ØMQ.
Assuming you already have Docker installed on your system, run the following command to create a virtual network which the client and server will communicate over using ØMQ.
docker network create zmq
Then run the following command from the project root to build the client and server environments and run the 'Hello World' example:
docker-compose up --build
This will run both the client and server and you should see the output of the client and server as one sends messages to the other. After the client has sent 10 messages it will automatically exit, leaving the server running. To stop the server just enter ctrl-c
In each of the Docker files in the zmq-hello-world-client-node and zmq-hello-world-server-node directories, search for the text --branch v4.2.1. This can be changed to any relase tags at https://github.com/zeromq/libzmq. Similarly the version of CMake used can be changed by examining the lines in each of the Docker files that follow the # Setup CMake comment
Assuming you already have Docker installed on your system, run the following command to create a virtual network which the client and server will communicate over using ØMQ.
docker network create zmq
To run the client container directly navigate to the zmq-hello-world-client-node folder and run
docker build .
When this completes you will see a message: Successfully built daf63168161f. Note that the ID at the end of the message will be different. Copy the ID and enter the command:
docker run -it --network=zmq daf63168161f
Using the ID copied from the previous step. The container will appear to start and hang, but it's just waiting for the server to start.
To run the server container directly navigate to the zmq-hello-world-server-node and run:
docker build .
When this completes you will see a message: Successfully built 0f46b3a6544c. Note that the ID at the end of the message will be different. Copy the ID and enter the command:
docker run -it --network=zmq --net-alias=zmq-hello-world-server-cpp 0f46b3a6544c
Using the ID copied from the previous step. The containers will now start talking to each other as the client sends through 10 messages before completing.
Assuming you are using the latest native version of Docker, run the following command to pipe the output of Docker to a URL that CLion will understand:
sudo socat TCP-LISTEN:777,reuseaddr,fork,bind=localhost UNIX-CONNECT:/var/run/docker.sock
Then follow the normal steps documented here to setup Docker to run your project. When you need to enter a URL for the Docker API, use tcp://localhost:777.
