If all this works, you are ready to start Dockerizing! Step 1: Building the Dockerfile The last command checks if Docker is successfully running, and then exits.
DOCKER RUN IMAGE INSTALLED ELSEWHERE INSTALL
Below is the quick and simple way to install Docker, but if you want the full configuration checkout the official docs. Dockerfileīefore we can use Docker, we must first install it. These are the files we will use with Docker. Once you have it downloaded, go into the folder and find the below files. The code you see will be for setting up this web app, but the steps are the same for any project. See those benefits? Cool, now we can start! Getting StartedĮnter your EC2 instance and clone Kangzeroos-ES6-React-Redux-Boilerplate from Github. This setup requires 1GB for the host OS and perhaps 600MB per container (because 300MB is hypothetically shared with the host OS), for a total of 2.8GB required. The most significant difference is that a container engine is more lightweight because it can share certain hardware resources with its host OS, unlike traditional VMs that require their own separate allocation.
On the right side is a container setup, which would run a container engine such as Docker. If each Guest OS needs 1GB of memory, and the host uses 1GB of memory, then the setup on the left would require 4GB total. A hypervisor is simply your VM manager responsible for allocating hardware resources to each virtual OS. On the left side is your traditional virtual machine setup using a hypervisor.
DOCKER RUN IMAGE INSTALLED ELSEWHERE HOW TO
Today we will learn how to setup and deploy Docker on Amazon EC2 in 3 easy steps!īefore we start, take a look at this high-level diagram (courtesy of ). That means full compatibility… no more worrying about OS versions, dependencies and differences between your development and production machines! And to top it off, it’s lightweight so you can run multiple Docker containers in the same machine (EC2 instance). The containerization service makes deploying microservices easy and stable, as each service can run an OS in its own virtual environment. By Kangze Huang Docker: Easy as build, run, done!ĭocker has been getting a lot of buzz recently, and for good reason.
