Hi!

Let’s start installing the latest Raspberry Pi OS image in an SD card. Next steps will be focus on how to access and control remotely your device you may want to follow this steps.

![raspberry Pi Images install SO](https://brunocapuano.files.wordpress.com/2020/12/raspberry-pi-images-install-so.png?w=716)

This tutorial and tips works for Raspberry Pi 3, 4 and Zero.

The version 1.6 of Raspberry Pi Imager includes a new feature that allows to

- Define HostName
- Enable SSH
- Configure Wifi
- Set locale

Directly from the tool pressing the [Config] button

![raspberry pi imager config](https://brunocapuano.files.wordpress.com/2022/03/raspberry-pi-imager-config.jpg?w=697)

_ **Note:** Open the setting using this button is new in the latest Raspverry Pi imager version._

We can define this settings on the tool screen.

![](https://brunocapuano.files.wordpress.com/2021/03/raspberry-pi-imager-advanced-options.png?w=348)

I’ll leave the old-school standard methods below just as a reference.

## Configure Wireless connection (if needed)

In the SD Card, you need to create a file named [**wpa\_supplicant.conf**] in the root of the SD card with the following information:

```

country=ca
update_config=1
ctrl_interface=/var/run/wpa_supplicant

network={
 scan_ssid=1
 ssid=" Your WiFi SSID"
 psk="You amazing password"
}

```

The file content is very straight forward to understand. Main values to complete are [ssid] and [psk].

_Once you put the SD card in the device and start the device, it will automatically connect to the configured WiFi._

## Enable SSH (if needed) 

If you also want to enable SSH, you need to create a blank file named [ssh] to the main partition.

_Once you put the SD card in the device and start the device, it will automatically enable the SSH service._

So, you need to create and copy 2 files to the root of your SD card

- wpa\_supplicant.conf
- ssh

## Find the IP address in your network

And that’s it, your Raspberry Pi will be connected to the Wifi and with SSH enabled. At this moment we can use a tool like **_AngryIp_** (see references) to detect the new device in the network

![](https://brunocapuano.files.wordpress.com/2020/01/angry-ip-find-raspberry-pi.png?w=543)

My new device IP is: 192.168.1.246

I’m trying to avoid Java updates, and even install java, so lately I use a mobile app: Fing, and after a search the results are nicer.

![](https://brunocapuano.files.wordpress.com/2021/01/find-detected-devices.png?w=469)

## Access via SSH

I used to like Putty to connect to my device, however during the past months I’ve been using Windows Terminal and Powershell. In order to access the device I need to execute the command

```

ssh user@deviceaddress

```

and my data is

- user: pi
- ip: 192.168.1.246
- password: raspberry

![](https://brunocapuano.files.wordpress.com/2020/01/access-to-raspberry-pi-via-ssh-with-windows-terminal.png?w=914)

You can now start working with your Raspberry Pi !

If you get a SSH error message similar to this one

```

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
---
Host key verification failed.

```

You need to run this command to fix the host hey.

```

# ssh-keygen -R <host>
ssh-keygen -R 192.168.1.247

```

_ **Important:** the default password is raspberry, please follow next step!_

## Change Password (if needed) 

The default password for the device is “raspberry”, and as usual, it’s recommended to change it. In order to do this, in the ssh terminal, let’s access to the device configuration

```

sudo raspi-config

```

This will open the configuration for the device.

![raspi config main menu](https://brunocapuano.files.wordpress.com/2020/12/raspi-config-main-menu.png?w=1024)

Option number 1 will allow us to change the password.

![](https://brunocapuano.files.wordpress.com/2020/12/raspi-config-change-password.png?w=1024)

## Rename the device (if needed) 

In the same section we can change the Host Name.

And define the new name for the Raspberry Pi device.

## Expand FileSystem

Another important option in the configuration is to expand the SD disk.In the same configuration screen, select

- 6. Advanced Options
- Expand File System

![raspi config advanced options](https://brunocapuano.files.wordpress.com/2020/12/raspi-config-advanced-options.png?w=1024)

Now we need to reboot and after the reboot the file system should have been expanded to include all available space on your micro-SD card. Reboot with the command

```

sudo reboot

```

## Update the device

There are 2 ways to update the device, using commands and using raspi-config.

- In the Raspi Config main menu, the option 8 will launch the update commands.
- If you prefer to manually type an update command, this one works for me

```

sudo -- sh -c 'apt-get update; apt-get upgrade -y; apt-get dist-upgrade -y; apt-get autoremove -y; apt-get autoclean -y'

```

![updates complete](https://brunocapuano.files.wordpress.com/2020/12/raspberry-pi-updates-completed.png?w=791)

Install neofetch

Neofetch is a shell script that requires bash 3.2+ to function. By default, it displays an ASCII art of your Distro’s logo. Neofetch supports almost 150 different operating systems. From Linux to Windows.

Installation is super easy, just run the command:

```

sudo apt install neofetch

```

And then run the command

```

sudo neofetch

```

The output will be similar to this one:

![raspberry pi 5 running neofecth](https://brunocapuano.files.wordpress.com/2024/04/rpi-run-neofetch.jpg?w=996)

## Install Docker

The information is available from the Official Docker Documentation

```

curl -fsSL https://get.docker.com -o get-docker.sh

sudo sh get-docker.sh

```

And then, a simple check for the docker version with the command

```

docker version

```

## Setup ssh password-less access to the Raspberry Pi

The main resource is an official one fro the Raspberry Pi org: [Passwordless SSH access](https://www.raspberrypi.org/documentation/remote-access/ssh/passwordless.md). Here is a quick resume for Windows 11 users. First let’s run this command

```

ls ~/.ssh

```

I already keys on my computer, so I found id\_sa and id\_rsa.pub.

![raspberry pi ssh keys](https://brunocapuano.files.wordpress.com/2021/08/raspberry-pi-ssh-keys.png?w=645)

Now, let’s copy them to the device. For this this command:

```

cat ~/.ssh/id_rsa.pub | ssh <USERNAME>@<IP-ADDRESS> 'mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys'

```

And that’s it! Now we can ssh the Raspberry Pi without password.

_ **Disclaimer:** you know that this is not a very secure practice?_

## Setup SSH password-less access to remote work with docker 🐳

Once we finished ssh password-less access, we can easily configure a TCP-enabled Docker.

I followed the next steps. First, let’s edit _docker.service_ with the command:

```

sudo nano /lib/systemd/system/docker.service

```

And add [-H tcp://0.0.0.0:2375] at [ExecStart] section:

![raspberry pi ssh password less docker](https://brunocapuano.files.wordpress.com/2021/08/raspberry-pi-ssh-password-less-docker-1.png?w=976)

And restart the device or just the needed services

- run _sudo systemctl daemon-reload_
- run _sudo systemctl restart docker_

## Run Docker 🐳 commands without sudo

Now let’s upgrade our docker commands, so we can run them without sudo. Just run this commands

```

sudo groupadd docker
sudo gpasswd -a $USER docker

```

And also restart the service:

```

sudo service docker restart

```

Install Rust

To install Rust run the following in your terminal, then follow the on-screen instructions.

```

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

```

These are the options, I’ll go with the default one

![rust install options](https://brunocapuano.files.wordpress.com/2023/01/image-10.png?w=942)

After a couple of minutes, we have rust installed !

![rust installed](https://brunocapuano.files.wordpress.com/2023/01/image-11.png?w=1024)

I closed my terminal and opened again, and I can test the rust and cargo version with the commands

```

rustc --version
cargo --version

```

![displaying rust and cargo version in the terminal](https://brunocapuano.files.wordpress.com/2023/01/image-12.png?w=1006)

I can even create a new app using cargo, edit the main file and run it!

![I can even create a new app using cargo, edit the main file and run it!](https://brunocapuano.files.wordpress.com/2023/01/image-13.png?w=1024)

Rust is working fine !

## Conclusion

And that’s it, we have our device updated and running with the latest software versions and we didn’t use a monitor! I’ll update this post frequently to make it relevant with my personal best practices.

Happy coding!

Greetings
