Chapter 2. Handling Docker Containers

In the previous chapter, we explained stimulating and sustainable concepts, which showed the Docker's way of crafting futuristic and flexible application-aware containers. We discussed all the relevant details of producing the Docker containers in multiple environments (on-premise as well as off-premise). Using these techniques, you can easily replicate these features in your own environments to get a rewarding experience. Therefore, the next step for us is to understand the container's life cycle aspects in a decisive manner. You will learn the optimal utilization of containers of our own as well as those of other third-party containers in an effective and risk-free way. Containers are to be found, assessed, accessed, and leveraged toward bigger and better applications. There are several tools that have emerged to streamline the handling of containers.

In this chapter, we will dig deeper and describe the critical aspects of container handling at length. A number of practical tips and execution commands for the leveraging of containers will also be discussed in this chapter.

In this chapter, we will cover the following topics:

• Clarifying the Docker terms
• Working with the Docker images and containers
• The meaning of the Docker registry and its repository
• The Docker Hub Registry
• Searching the Docker images
• Working with an interactive container
• Tracking the changes inside the containers
• Controlling and housekeeping the Docker containers
• Building images from containers
• Launching a container as a daemon
