Importing CLI Context in Docker

Hello friends! Today we want to talk about Docker and the concept of "context" in that context. Docker is an attractive tool for virtualization and container management. We can easily manage containers using the Docker CLI. One of the interesting features of Docker is the ability to use different contexts that allow us to work on different machines or connect to various services.

Contexts provide us with the ability to manage different configurations for each environment that we work in, maintaining a separation between them. For example, you can have one context for development, one for testing, and one for production. This feature helps us avoid cross-environment interference and easily switch between environments.

To import a new context in Docker, we use the command docker context import. With this command, we can introduce a context file to Docker and set appropriate configurations for accessing that environment. Therefore, if you also want to add a new context to your Docker CLI, continue with us!

Now let's take a look at some examples of this command to better understand how we can use it. We will also examine more details about the options and parameters of this command.

docker context import my-context --file context-file.tar.gz

Code Explanation

Now let's go through this line of code step by step:

This command tells Docker to import a new context named my-context. This context includes all the configurations stored in the file context-file.tar.gz.

By using this command, you can manage different environments without the need to rebuild them, easily accessing your work. An important point is to ensure that the file in question is accessible before importing the context.
