Let’s say one of your micro services is running on http://localhost:3000

If you already have a nginx service running on the server, create a server block like this:

1

vim /etc/nginx/sites-available/domain.com.conf

server {

  server_name domain.com;

  root /var/www/html;
  index index.html;

  location / {
    proxy_pass http://localhost:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
  }

}

For more advanced (more so production ready) configuration, use below instead:

Let’s say there are two pull requests open on a project repository.

Each change has its own branch like this:

• master
• feature/add-base64-endpoint
• feature/add-user-agent-endpoint

The challenge is to use git rebase to add both changes to master. When you finished, your master branch should have three commits in the following order:

• feat: add user-agent endpoint
• feat: add base64 endpoint
• init

Okay, let’s go!

git clone repo_url
git status
git checkout feature/add-base64-endpoint
git rebase master
git status
git checkout master
git merge feature/add-base64-endpoint
git status
git checkout feature/add-user-agent-endpoint
git rebase master

Oops! You now see rebase conflict!

Let’s update the Password Authentication parameter in the ssh service config file:

1

vim /etc/ssh/sshd_config

Wait, what? I can’t even find the sshd service?

Install it then:

1
2

sudo apt update
sudo apt install openssh-server

In the /etc/ssh/sshd_config file, uncomment this line:

1

#PasswordAuthentication yes

Done.

Oops! Don’t forget to reboot! 🙂

Or just run:

Back up the current sources.list first.

1

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

Well, run this command then.

1

sudo echo "deb http://http.kali.org/kali kali-rolling main non-free contrib" > /etc/apt/sources.list

Now you can run apt update command!

Happy networking! 😎

First things first. Let’s check the directory structure of the app.

Let’s take a look into the DB image first.

I thought importing dump data should be working if I used CMD or ENTRYPOINT.
