![]() ![]() The Django runtime environment will not affect the PHP runtime environment and vice versa.īesides, the reuse of resources. Second, the containers are independent, do not conflict with each other.First, the containers do not conflict or damage anything on the host machine.By creating different, independent environmental containers. This may conflict with the environment on the virtual machine.ĭocker solves that problem easily. Or if you have setup virtual machine environment to run PHP, now you want to setup virtual machine to be able to run Django simultaneously. With traditional virtual machine, if you install the dependencies fails, you may have to recreate the virtual machine. So you’ve got environments with different operating systems already, on the same local machine and even extremely fast. With Docker, you just need to create other containers from different OS images. Traditionally, you will have to create different virtual machines and install operating systems on it. Each container will let it perform a test task. Now you can create multiple identical containers from the same original image file. If you use a single machine, it will take a long time. To test the software, many people and many machines are needed at times. With Docker, you only need to share the environment image file with the whole team, so make sure the environment is the same between the members. ![]() Store and share the project environment settings for the teamĮach project can have many people, requiring environmental setting to be meticulously documented, so that everyone can understand. Why? Because the environment on both sides are not the same.įor example, lets say your machine runs python 3.5 but the CentOS server runs python 2.7, so your code fails because of difference in version.Īnd therefore, you can use Docker to help you simulate the server environment perfectly without changing anything on your local machine. Imagine a situation when you program the software on the local machine very well, but when it was uploaded to the server, it didn’t work. Simulate the server environment at the local machine In other words, Docker is the platform that lets you create, manage, modify, deploy and work with containers. Simply understand, Docker is a platform (both commercial and free) that provides services and tools, allowing you to create packages and run your programs on different environments as quickly as possible. Now, you understood that the container will help you to have a software development environment quickly and not conflict with the rest of the server.īut, how to get containers or perhaps how to create containers? How can we work with containers and manage containers? And later, you just need to run the file and you have the environment ready as you want. You can pack all those things into one file. Therefore, to answer this problem container came into existence. Imagine that, every time you start writing a software, you need to install dependent packages to work, from OS, web server, php version, mariadb, and so on. The software companies race on technology, software development lifecycle needs to be done continuously and quickly. With the above definition, you’re still wondering what the container does? What is a container?Īccording to information from the docker home page, the container defines the following:Ī container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. ![]() So, coming to very first question that would pops up in any mind, what is docker? What does it do and why should we use it?īefore we find out what it is, let’s see this one first. Or, just in case you haven’t heard about docker, let’s understand it from very beginning. If you are reading this article it means you might have heard a lot about docker. ![]()
