Docker makes it easier for developers to build, test, and deploy applications without worrying about dependencies by packaging them in standardized units called containers. Docker-compose is an advanced, must-have tool for managing multi-co...

When using docker-compose up, we can see the logs of all containers in the YAML file; however, if we specify a specific container service, the output will not show any service dependencies in the log. Therefore, this article will explore ho...

Both docker and docker compose docker run Docker containers. The two Docker constructs are comparable, but that's about it. This article will discuss docker compose the main differences between docker and . Differences between Docker and Do...

As we develop our applications, we often make changes or add more features to make the application more effective for the different users who interact with the application. When using Docker, we need to ensure that the changes or features w...

There are different types of communication on the Internet, the most common ones include file transfers, sending emails, and serving web pages. To make this communication possible, we make use of port numbers that help identify the type of...

Docker containers work by leveraging network drivers that are created during the installation of Docker. The default drivers available to us include bridge and host networking. When we create containers without specifying a network, they ar...

Logs are information recorded by the application when a specific event or state occurs. They help us monitor the application and take necessary actions. For example, when we deploy an application to a production environment, logs can help u...

The Docker daemon provides essential information about the general state of your microservices architecture. Unfortunately, container-centric logging techniques allow you to collect relevant data from your services but provide little inform...

A Dockerfile is a text document that contains all the commands used to build a Docker image. Recently, we have seen Docker being widely used as the default tool for managing configurations and automating deployments. Advanced features such...

Typically, when most developers start using docker, after going through all the processes of pulling images, building them, and running containers, removing a container defeats the purpose of doing so. However, for experienced developers, t...

Environment variables are used to add additional configuration or metadata to aid in the development of an application, and can exist in different forms. For example, when developing a Java application, we usually set an environment variabl...
