Installing useful tools

All steps must be run from the /home/<user> folder with sudo privileges. If you are going to customize or install as root, please set paths, folders and tools according to your new configuration.

1. Before continue, follow the my5G-core installation steps from here

2. Install some tools required to develop, monitor and containerize:

   System update

   sudo apt update && sudo apt -y upgrade
   

   Tools installation

   sudo apt -y install tcpdump wireshark curl snap
   

   Docker installation

   curl -fsSL https://get.docker.com -o get-docker.sh && sudo sh get-docker.sh
   

   Docker-compose installation

   sudo curl -L "https://github.com/docker/compose/releases/download/1.25.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   
   sudo chmod +x /usr/local/bin/docker-compose && sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
   

   JetBrains GoLand IDE

   sudo snap install goland --classic
   

   Jetbrains GoLand IDE has "For Open Source projects" and "For students and teachers" distributions, both free. Click here to register your account.

Opening the project in GoLand

1. Open the project with GoLand

   • The project folder should be ~/my5G-core

2. Check that $GOPATH and $GOROOT are recognized by GoLand and points to the right folders

   • Acess menus: File -> Settings
   • $GOROOT and $GOPATH should look like below:

   

   • $GOPATH should show your user instead of my5G-core

   

3. Now, the IDE should be able to recognize the imports from external libraries and packages under my5G-core/src/
