Get Familiar With Docker Before Dockerizing Your Application
Do you want to Dockerize your React app?
Read this blog till the end and understand how to run your react application in docker
What is Docker?
Docker Inc. developed docker and introduced it in 2013. Docker is a collection of PaaS (platform as a service) products that implement virtualisation at the OS level by separating software from its environment. It provides isolated states named containers. The benefit of containerizing React app is that the entire application can be packaged into various containers concerning their libraries and multiple dependencies. Docker helps in streamlining the development and deployment process.
You can visit the documentation and learn more about Docker.
Why do we need Docker Containers?
If you are wondering, what is the advantage of using docker? What is the use of docker and kubernets? What is the use of Docker in devops? Why to use docker containers? Doesn’t it affect the performance issues and complicate things? I partially agree with this. After reading several blog posts, I started developing different perspectives towards Docker container. It might complicate and mess with the applications performance if you have just implemented it for the sake of implementing it, without knowing its proper use-case.
If you have correctly dockerize the application, it will actually give you more and better control of your application.
How to install Docker?
You can click here to download the setup and install Docker on your system. Docker layers the filesystem and then builds the container as per the specifications of individual containers provided in the Dockerfile. We will see what is Dockerfile in the next section when we will dockerize React app.
Once you have completed the installation process, run this command to verify whether it’s done correctly or not.
docker- -version
OR
docker -V
Let’s what do we need before starting our application journey with Docker.
Advantages and Disadvantages of Docker
Docker consists of a Docker container that works like Virtual Machines but is far more organized and granular. Let’s see what the advantages and disadvantages of Docker are.
—Docker Advantages
-Docker fastens the software deployment.
- Docker provides easy portability of applications.
- Docker is more beneficial for applications having microservices architecture.
— Docker Disadvantages
- Docker is unable to solve your security issues. It can add a security layer, but it would be a general program for securing the application.
- Docker creates performance overhead because of overlaid networks and
interfaces between containers.
- It is hard to manage the data when you’re dealing with heavy applications.
Before dockerize your application, it’s essential to know how Docker will help your application as Docker isn’t beneficial to all the applications.
I believe this is enough overview regarding Docker introduction. If you are looking for a helping hand how to Dockerzie React app, check out this blog post on how to dockerize React app.
