Hi!
Letโs 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.
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
_ 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.
Iโll 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 thatโs 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
My new device IP is: 192.168.1.246
Iโm 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.
Access via SSH
I used to like Putty to connect to my device, however during the past months Iโve 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
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 โraspberryโ, and as usual, itโs recommended to change it. In order to do this, in the ssh terminal, letโs access to the device configuration
sudo raspi-config
This will open the configuration for the device.
Option number 1 will allow us to change the password.
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
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'
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. Here is a quick resume for Windows 11 users. First letโs run this command
ls ~/.ssh
I already keys on my computer, so I found id_sa and id_rsa.pub.
Now, letโs 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 thatโs 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 ๐ณ
Once we finished ssh password-less access, we can easily configure a TCP-enabled Docker.
I followed the next steps. First, letโs 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:
And restart the device or just the needed services
- run sudo systemctl daemon-reload
- run sudo systemctl restart docker
Run Docker ๐ณ commands without sudo
Now letโs 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, Iโll go with the default one
After a couple of minutes, we have rust installed !
I closed my terminal and opened again, and I can test the rust and cargo version with the commands
rustc --version
cargo --version
I can even create a new app using cargo, edit the main file and run it!
Rust is working fine !
Conclusion
And thatโs it, we have our device updated and running with the latest software versions and we didnโt use a monitor! Iโll update this post frequently to make it relevant with my personal best practices.
Happy coding!
Greetings
