In the labs in this chapter, we will run containers and interact with them. We will also review some examples, limiting their resources and formatting and filtering the command output.
To run these labs, deploy environments/standalone-environment from this book's GitHub repository (https://github.com/PacktPublishing/Docker-Certified-Associate-DCA-Exam-Guide.git) if you have not done so yet. You can use your own CentOS 7 server. Use vagrant up from the environments/standalone-environment folder to start your virtual environment.
If you are using standalone-environment, wait until it is running. We can check the statuses of our nodes using vagrant status. Connect to your lab node using vagrant ssh standalone. standalone is the name of your node. You will be using the vagrant user with root privileges using sudo. You should get the following output:
Docker-Certified-Associate-DCA-Exam-Guide/environments/standalone$ vagrant up
