Unraveling the Supernatural: Docker Inspect Container Secrets

Introduction

In this lab, we will explore the Docker "inspect" command by immersing ourselves in a scenario involving a mysterious gateway to the supernatural world. We play the role of a prominent figure, the "Supernatural Leader," who needs to inspect Docker containers to unravel the hidden secrets behind the supernatural gateway and protect our world from potential threats.

Inspect Container Metadata

In this step, we will start by inspecting the metadata of a Docker container.

Firstly, create a sample network using the following command:
```
docker network create my_network
```

Then, launch a new container and connect it to the created network:

docker run -d --name my_network_container --network my_network alpine sleep 1d

Inspect the metadata of a running container with the following command:
```
docker inspect my_network_container
```

Inspect Container Configuration

Next, we will delve deeper into the inspect command by examining the configuration of a Docker container.

Using the same container as in Step 1, inspect the configuration settings:
```
docker inspect --format='{{json .Config}}' my_network_container
```
Analyze the output to understand the container's configuration and how it aligns with the desired state.

Explore Container Network Settings

In this step, we will focus on exploring the network settings of a Docker container.

Inspect the network settings of the container:
```
docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' my_network_container
```
Understand the container's networking configuration, including its IP address and network aliases.

Summary

In this lab, we delved into the Docker "inspect" command to gain valuable insights into container metadata, configuration, and network settings. By immersing ourselves in a supernatural scenario, we successfully harnessed Docker's inspect capabilities to unravel the mysteries behind the supernatural gateway. This lab not only enhanced our Docker skills but also provided a creative and engaging learning experience.
