#containers channel on the back4app community on slack anytime you can also contact us at community\@back4app com 1\ prepare your react application to prepare your react application for deployment on back4app containers, follow these steps ensure you have the latest version of node js and npm installed on your local machine check your version with node v and npm v if you need to update, visit node js https //nodejs org/en/download/ and follow the instructions create a new remix application using the remix cli by running npx create remix choose a suitable name for your project and select the preferred development environment change into your project directory with cd your app name install all the required dependencies using npm install run your application locally with npm run dev to ensure everything is working as expected 2\ dockerization to dockerize your remix application, create a dockerfile in the root of your project directory with the following contents from node 14 workdir /app copy package json / run npm ci copy run npm run build expose 3000 cmd \["npm", "run", "start"] this dockerfile specifies node js 14 as the base image, sets the working directory, installs the dependencies, copies your application files, builds the production version of the app, and exposes port 3000 3\ test your project locally before deploying your application, test it locally with docker build the docker image with docker build t your image name run the docker container with docker run p 3000 3000 your image name visit http //localhost 3000 in your browser to verify the application is running as expected 4\ push your project to github to push your project to a github repository, follow these steps initialize a new git repository in your project directory with git init add all files to the repository with git add commit the changes with git commit m "initial commit" create a new repository on github, and copy its url add the remote repository with git remote add origin your repository url push your changes to the remote repository with git push u origin master 5\ deploy your application on back4app containers to deploy your rails app on back4app
