How to Install Docker and Portainer on a Raspberry Pi!

Today we are going to look at how to install Docker and Portainer on a Raspberry Pi.

Raspberry Pi: Docker & Portainer Setup! (Tutorial) (https://youtu.be/YjszoDGsqfo)

This process is very simple, but we will be using Portainer in future tutorials to setup different docker containers, so this will be the first thing we are going to look at. The Raspberry Pi 4 is pretty powerful for being as small as it is. Combine that with the fact that there are a ton of great docker containers that don’t require powerful CPU’s, running certain Docker containers on a Raspberry Pi becomes a great option for a lot of people.

The steps below will utilize a fresh install of the Raspberry Pi OS. If you aren’t sure how to do that, I have instructions here.

Required Hardware

Raspbery Pi 4: Docker and Portainer can be installed on older Raspberry Pi devices, but the Raspberry Pi 4 has more processing power than older devices which will lead to better performance.

Micro SD Card: Don’t need anything crazy here, just a good Micro SD card with enough storage space.

Raspberry Pi 4 Case: This is one of my favorite cases for the Raspberry Pi 4, but any case will do.

Power Supply: Needed to power your Raspberry Pi.

HDMI Cable: I generally SSH into my Raspberry Pi devices, so this is only required if you intend on connecting your Raspberry Pi to a display.

Instructions - Install Docker and Portainer on a Raspberry Pi

1. Ensure that your Raspberry Pi is up to date by running the commands below.

sudo apt update
sudo apt upgrade

2. The next thing we are going to run is the script to install Docker on our Raspberry Pi. Portainer is a GUI that manages Docker containers, so we need to ensure Docker is installed.

curl -sSL https://get.docker.com | sh

3. After the script completes, we need to give our Pi user account access to Docker.

sudo usermod -aG docker pi

4. After the user has been added, we are going to run a command to download the latest Portainer image for the ARM processor (which is what the Raspberry Pi uses).

sudo docker pull portainer/portainer-ce:linux-arm

5. Our final step is to create a new container that will run Portainer. If you are already using port 9000 on your Raspberry Pi for something else (this is unlikely), you will need to change the ports below.

sudo docker run --restart always -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:linux-arm

6. You should now be able to navigate to the IP address of your Raspberry Pi and port 9000 to access Portainer. When you get there, create a username and password.

http://[RASPBERRY_PI_IP_ADDRESS]:9000

7. Select Local and Connect.

8. You should now be connected to Portainer!

Conclusion

This is a pretty straight forward process, but we will be utilizing it in future tutorials. I decided it was best to create a specific tutorial for this rather than installing Docker/Portainer in all future tutorials. If you have any questions, please leave them in the comments. Stay tuned to see what containers we will be adding to our Raspberry Pi! Thanks for reading!

Will Portainer work well on a Synology NAS?

  Portainer does work on a Synology NAS. I set it up a while ago but noticed that I wasn’t really using it so I removed it. If I get some time, I will look into some of the features it offers that the Synology Docker GUI doesn’t. Thanks for checking out the tutorial!

  Did you receive any errors during the installation process? If not, are you willing to start from a fresh micro SD card to try again? It’s tough to troubleshoot since there aren’t that many commands, but if you received specific errors, we can look into those errors.
  Let me know and we will continue troubleshooting!

Couple of things:-
1) should you update your steps for portainer 2.0 / portainer-ce
2) I get a dpkg error Code 1 at the end of The “ curl -sSL https://get.docker.com | sh” script

  1. I have been restraining from updating the the documentation to Portainer 2.0 because I’ve had a lot of problems with it on my Raspberry Pi. I don’t want to indirectly break any of the containers that people might have running, so until I can isolate what my issues are, I am holding off on updating the documentation.
  2. What error are you receiving?
  Let me know and we can continue troubleshooting!

    I also got the error Dan is describing and I think because of that when I try the command “sudo docker pull portainer/portainer:linux-arm” I get “Cannot connect to the Docker daemon at ect ect is the docker running?”

      That’s definitely a weird issue and I’m not entirely sure why it’s happening. It almost sounds like Docker isn’t running. Does Docker install properly? If it does, can you try and run this command and see if it works?
      service start docker
      Let me know and we can continue troubleshooting!

  Had the exact same problem, and it ended up being solved by updating my Raspberry Pi (3B+). “rpi-update”

Hi – Not able to “navigate to the IP address of your Raspberry Pi and port 9000 to access Portainer”.
Using browser I get error
“This site can’t provide a secure connection192.168.1.125 sent an invalid response.
ERR_SSL_PROTOCOL_ERROR”.
Solution was to use http:// rather than https://

  You are correct – I have a habit of typing https so I apologize for the mistake. I have updated the tutorial to reflect this. Thanks so much for the feedback!

I have a Raspberry Pi4 (ARMv7) and follow your instruction but get an Waring/error. Do you have any ideas on how to fix this? See the copy from the terminal window below:NB: I want to use e.g. port 9100 since I use port 9000 for something else:

  From what I’m searching, this is a “new” error for a lot of people running Docker on a Raspberry Pi. Are you running Docker 20.10 by any chance? I am thinking that downgrading might be the only temporary solution. Does everything work or it won’t continue the install?

  From what I’m reading, this is a new issue caused by Docker 20.10. Does the container work properly? Or does it throw that error and then never start?

Hello from Docker!
This message shows that your installation appears to be working correctly.
When i try to access Portainer in a browser, using http://192.168.86.9:9100/ it gives the message: This site can’t be reached 192.168.86.9 refused to connect.
. . .and the IP is ok . . .
[email protected]:~ $ ping 192.168.86.9

64 bytes from 192.168.86.9: icmp_seq=1 ttl=64 time=0.192 ms
How do I downgrade, if you think that is the solution?

  That’s a great question. My Raspberry Pi is packed away right now (I’m in the process of moving), but you’re probably better off uninstalling Docker and reinstalling it using an older version.
  This thread should show you how to do it (I’m sorry that I can’t test it): https://forums.docker.com/t/how-can-i-install-a-specific-version-of-the-docker-engine/1993
  With that said, you also have the option of waiting a little while and running periodic updates to see if the issue is resolved in a newer version.
  Sorry for the somewhat empty response. I wish I could provide further details, but if there’s anything I can do to help, please let me know!

Hi,
I have the same problem as Thomas, sadly I can’t seem to get around it. I have a fresh install using this guide and I chose to install a specific version of docker using the guide you posted in the latest comment. But I still get the same problem sadly.
I have had any time to look into it?

I figures it out, I didn’t get it to work with the first suggestion in the guide you linked to. I had to dig a bit deeper and find this guide: https://medium.com/@gauravsj9/how-to-install-specific-docker-version-on-linux-machine-d0ec2d4095
Then I could install the latest available version of 19. These are the steps I used:
I had to find the version to use:
sudo apt-cache policy docker-ce
and for me it was 5:19.03.14~3-0~raspbian-buster
Then I could do:
sudo apt-get install docker-ce=5:19.03.14~3-0~raspbian-buster
Note: Remember to remove the old version you had. Instructions in this guide: https://medium.com/@gauravsj9/how-to-install-specific-docker-version-on-linux-machine-d0ec2d4095
Then the rest of this guide worked perfectly!

Hi,
when I try following these steps:
curl -sSL https://get.docker.com | sh
I’m receiving:
[email protected]:~ $ curl -sSL https://get.docker.com | sh
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
Any ideas how to install via a different route?
Thanks

  I haven’t seen that error in specific, but it’s definitely a weird one. Are you running a DNS server or something else that’s checking your traffic and allowing/rejecting the connection?
  That page is just a script that runs certain commands to install Docker. You can view the script here: https://get.docker.com/
  Since you will most likely have to run the same commands, I’m not sure you’ll have much success using a different method. Are you using a fresh install of the Raspberry Pi OS?
