Spheron is a decentralized cloud storage platform that provides an all-in-one solution for building and deploying DApps1. In this article, we will show you how to dockerize your Next.js application and deploy it on Spheron Compute.
What is Docker?
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package.
What is Next.js?
Next.js is a popular React-based framework for building server-rendered or statically-exported React applications. It provides features such as automatic code splitting, server-side rendering, and more.
Dockerizing your Next.js application
To Dockerize your Next.js application, you need to create a Dockerfile in the root of your project directory. This file contains instructions for building a Docker image of your application. Here is an example Dockerfile for a Next.js application:
Use an official Node.js runtime as the base image
FROM node:alpine
Set the working directory
WORKDIR /app
Copy package.json and package-lock.json
COPY package*.json ./
Install dependencies
RUN npm install
Copy the rest of the files
COPY . .
Build the app
RUN npm run build
Expose port 3000
EXPOSE 3000
Start the app
CMD ["npm", "start"]
This Dockerfile uses the official Node.js runtime as the base image, sets the working directory to /app, copies the package.json and package-lock.json files, installs dependencies, copies the rest of the files, builds the app, exposes port 3000, and starts the app.
Once you have created the Dockerfile, you can build the Docker image by running the following command in your terminal:
docker build -t my-nextjs-app .
This command builds a Docker image with the tag my-nextjs-app using the Dockerfile in the current directory.
Deploying your Next.js application on Spheron Compute
Once you have Dockerized your Next.js application, you can deploy it on Spheron Compute. To do this, follow these steps:
Go to the Compute section in Spheron.
Create a new cluster by clicking on the โNew Clusterโ button.
Click on the โSelect from marketplace appโ button for fast-track deployment.
Select the IPFS template from the marketplace.
Choose your instance plan and click on the โDeployโ button.
Once your IPFS node is up and running, you can upload files to IPFS via WebUI or HTTP-Client, and access files using IPFS Gateway.
Thatโs it! You have successfully dockerized your Next.js application and deployed it on Spheron Compute. With Spheronโs all-in-one solution, you can easily build and deploy DApps without having to worry about complicated infrastructure.
