This article will guide you through the necessary steps to get started with Dokku.

Setting up an account on Digital Ocean

The first step to getting started with Dokku is setting up a hosting account on a platform like Digital Ocean. Digital Ocean is a reliable cloud hosting platform that offers VPS hosting services.

To set up an account on Digital Ocean, go to their website and click on “sign up.” You will be required to provide your name, email address, and billing information. Once you have completed the sign-up process, you can log in and create a new Droplet for Dokku.

Creating a new Droplet for Dokku

A Droplet is a virtual private server that you can use to host your applications. To create a new Droplet for Dokku, click on “Create Droplet” on your Digital Ocean dashboard.

Select the Ubuntu distribution as your operating system, and select the “basic” plan, which is suitable for testing purposes. In the “additional options” section, select “SSH keys” and add your SSH key for secure access to your server.

Finally, give your Droplet a name, and click on “create.”

Deploying a Django Application

to Dokku

Deploying a Django application

to Dokku is a straightforward process. The first step is to set up a buildpack that will be used to compile your application’s code.

A buildpack is a set of scripts that are used to build, configure, and run applications. To create a buildpack for your Django application, create a new file named “apt-packages” in the root directory of your application.

Inside that file, list the Ubuntu packages that are required for the application. Then create another file named “requirements.txt” and include all the required Python packages.

Once the buildpack is ready, you can deploy your Django application by pushing the code to your Dokku server. Use the Dokku CLI to create a new application and link it to your Digital Ocean droplet.

To push the code, add Dokku as a Git remote, and push the code to the remote using the “git push” command. Pushing Code

Adding Dokku as a Git remote

To push code

to Dokku, you need to add it as a Git remote.

Navigate to your application’s directory and run the following command to add Dokku as a remote:

“`

git remote add dokku [dokku_user]@[server_ip]:[app_name]

“`

Where `[dokku_user]` represents the Dokku user account you set up, `[server_ip]` represents the IP address of your server, and `[app_name]` represents the name of your application. Pushing code

After adding Dokku as a Git remote, you can push the code to your Dokku server using the following command:
