Setting Up Dokku in AWS EC2

Dokku is a popular open-source platform that simplifies the process of deploying and managing applications. In this guide, we'll show you how to set up Dokku in an Amazon Web Services (AWS) EC2 instance.

Step 1: Pass the Public SSH Key to the AWS Server
Use the following command to pass the public SSH key to the AWS server:

# cat <public_key_dir> | ssh -i <aws_key_dir> <username>@<ip_add/domain> sudo dokku ssh-keys:add <KEY_NAME>
  cat ~/.ssh/id_rsa.pub | ssh -i "intelli_masuk.pem" ubuntu@example-address.compute.internal.compute.amazonaws.com sudo dokku ssh-keys:add admin

Step 2: Remote Dokku Command in a Server from Local Machine

To run a remote Dokku command in the server from your local machine, use the following command:

# ssh dokku@<ip_add> <DOKKU_COMMAND>
  ssh dokku@10.10.10.10 apps:create hobby

Step 3: Setting Up the Global Domain for a Dokku Server
To set up the global domain for a Dokku server, follow these steps:

Remove the global domain:

 # ssh dokku@<IP_ADD> domains:remove-global <SERVER_ADDRESS>  
   ssh dokku@10.10.10.10 domains:remove-global example-address.compute.internal

Add the global domain:

 # ssh dokku@<IP_ADD> domains:add-global <DOMAIN_NAME>  
   ssh dokku@10.10.10.10 domains:add-global example.com

Step 4: Setting Up the SSL Certificate Plugin for a New Dokku Server

To set up the Dokku Let's Encrypt plugin for the first time, use the following commands:

 sudo dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git
 dokku config:set --global DOKKU_LETSENCRYPT_EMAIL=your-email@your.domain.com

Step 5: Deploying an Application in Dokku Server
To deploy an application in the Dokku server, follow these steps:

Add a Git repository in the Dokku server:

 # git remote add <repo_name> dokku@<ip_add/domain>:<app_name>
   git remote add dokku dokku@10.10.10.10:hobby

Create an app in the Dokku server from your local machine:

  # ssh dokku@<ip_add> apps:create <app_name>
    ssh dokku@10.10.10.10 apps:create hobby

Deploy the Git repository in the Dokku server:

 # git push <REPOSITORY_NAME> <BRANCH_NAME>
   git push dokku main

Step 6: Setting Up a Domain for an App
To set up a domain for an app, follow these steps:

Report the app's domains:

ssh dokku@10.10.10.10 domains:report hobby

Set the domain for the app:

 dokku domains:set hobby test-preview.intellidigital.com

Add the domain remotely:

ssh dokku@10.10.10.10 domains:add hobby hobby.theme-preview.intellidigital.com

Step 7: Enabling the SSL Certificate for an App
To enable the SSL certificate for an app, follow these steps:

Set the email to get the SSL certificate:

ssh dokku@10.10.10.10 letsencrypt:set hobby email maskawat.masuk@intelli.global

Enable the SSL for the app:

ssh dokku@10.10.10.10 letsencrypt:enable hobby

Automatically update the letsencrypt certificate

ssh dokku@10.10.10.10 letsencrypt:cron-job --add

Python module in simple way

What is Module in python?

Module is just a file with a .py extension, which contain some Python code. The python code can be a a set of functions or variables.

When do we need to use modules ?

Suppose, we are making an application to generate a diet chart. Based on some information about a person the application will generate a diet chart. So, Every time some set of specific function is calling, to make this simple we can make a module name chart.py with a set of specific functions to reuse in different applications again and again.

Create a Module.

To create a module name chart, we just need to write some code in file and save the file with .py extensions. So, the name of the python file is the name of the module.

To import a module

import chart

Python from and import statement

To import a specific function we can use from and import statement.

from chart import generate

Module renaming

To change the import name of the module we can use as

import chart as ch
