Using docker to install BrewPi


#42

Messing around a bit with getting the legacy container on the same Pi that my Spark 3 is running on. Have both the Spark 3 and the Arduino plugged in to USB, so the second device is /dev/ttyACM1 as expected. When creating the container, I am storing the data in ~/brewpi-legacy. All is working, but have to find a clean way to create the ~/brewpi-legacy directories with the right permissions for a clean install.

Any suggestions on adapting the Synology / unRAID configs for use on a QNAP NAS?
Where to start? New to Docker, new to the NAS as well… Don’t really want to mess with my rpi config right now so looking for an alternative for the new build.

Noob question related to docker containers:

The BrewPi script master branch is currently at version 0.5.2, but it looks like we’re up to RC3 on the 0.5.3 branch. When the official release moves to 0.5.3, will this involve creating a new container, switching to that one, and retiring the previous container? In other words there is no longer a notion of running updater.py to do an in-place upgrade of the code?

If so, does this simply involve using ssh to do another sequence of “docker pull”, “docker stop”, “docker rm”, and “docker run”?


#45

Both are possible. The running container can pull the latest code, or the full container can be recreated.

back at it… have a docker image up and running on my QNAP NAS using the brewpi-ubuntu:latest image.
I have a filesystem on my NAS named /brewpi-data which I’ve added as /data to the docker image.
the log files in /data/logs are showing up owned by root and the brewpi Maintenance logs UI shows “Cannot open log file /home/brewpi/logs/stderr.txt”…

looking at the processes running, I do see that the python brewpi.py script process is owned by “brewpi”.
Why are the logs getting created as root?

root@71dc4adb9fb5:/home/brewpi# ps -eaf | grep brewpi
root 130 1 0 03:24 ? 00:00:00 sudo -u brewpi python -u /home/brewpi/brewpi.py
brewpi 131 130 0 03:24 ? 00:00:01 python -u /home/brewpi/brewpi.py
root 143 92 0 03:30 ? 00:00:00 grep --color=auto brewpi

The /data volume contents are owned by brewpi:brewpi, but the log files were created with root:root ownership. What is wrong?

Just an FYI for anyone else – I’ve spent the morning fighting hypriot using a mix of the documentation on the wiki and hypriot’s documentation.

With the current version of hypriot, they changed how the device-init works. It is now /boot/user-data on the image. A big thing to remember is that the content defined in the file is only created on the first boot. If you find that you missed a step or forgot to change something after you’ve already booted the raspberry pi, you need to make the necessary changes to the OS manually.

Another gotcha that I found people talking about with the rasberry pi 3 is that you have to edit the /boot/config.txt and set “enable_uart=0” if you want to use the wifi. Supposedly, the onboard wifi and uart use the same pins, so you can’t use both.

I used an issue reported on their github (https://github.com/hypriot/blog/issues/60) to figure this all out.


#50

can you guys @fatbaldingoldgit please include me or let me know how I can help - I am literally in the process of trying to install all of it. I have the RasPi and the spark 3 connected via USB currently and the Docker App installed on the Mac and the image i downloaded or picked was brewpi omni and ubuntu (i wasn’t sure which to pick) please let me know. - @Elco lco has me on Skype so I can screen share or whatever you need along the way - happy to help


#51

I think the install process should work as described in the wiki–it’s just the update process from docker thats a little undocumented at the moment.

From your post it sounds like you installed docker on your mac. This is fine if that’s where you want the brewpi webserver to be, but in that case you don’t need the raspberry pi. If you want the webserver to be on the pi (nice because you can keep it on 24/7 and thus log beer/fridge temps 24/7) then you need to install docker on the pi itself (or install an OS to the pi that comes pre-installed with docker). I’m going to list the basic steps below and if you let me know which one(s) you are stuck at, I’ll try to offer some more detailed guidance.

  1. install an OS of some sort on the Pi (ie. rasbian, hypriot, etc.)

  2. make note of the ip address of the Pi (and spark 3 if you want it to connect to the pi via wifi), edit your router settings so these ip addresses are both reserved for these devices.

  3. connect to the pi vi ssh OR connect the pi to a monitor and keyboard and open a terminal

  4. install docker on the pi if not already installed

  5. use docker to pull a brewpi image, I use the raspian one because it is customized for pi hardwarve (you can also pull a portrainer image as well for visual UI for controlling docker)

  6. choose whether to use USB or wifi for the pi to connect to the spark, edit docker command and config file accordingly (for USB you need to add a parameter to the docker deploy command, for wifi you need to edit a line in the brewpi config file).

  7. From your normal computer enter the ip address of the pi (from step 2) into your web browser, the brewpi UI should pop up, and if step 6 was successful, it should say “script running.”

  8. at some point you’ll likely need to update, and this is where the current docker installs seem to have a slightly different (and undocumented) workflow. So you’ll need to stay tuned on best practices for updating.

Like I said, just let us know what step(s) you are stuck on and provide some details on what you’ve tried, what happened and what you expected would happen and I can try to help out.


#52

Well I may have gone backwards - I re-installed Raspberrypi (i did the Firmware upgrade and got a kernal panic error during boot so…) - whole OS on my SD card on the RPi3. I can ssh to it via my local network and its also booted and I can see the KDE desktop etc.
Maybe this is a misunderstanding but I want “Docker” as an Application/Program, not as a OS to boot into? is that an option? Cause I already used Etcher for ANOTHER 8GB SD Card that I flashed on my windows PC. The SD card shows up as SDA1. And currently it has the hypriotOS name on it.
So can I plug the 8GB SD card into the RPi3 using the 32GB microSD as its boot OS drive and load it that way?
I ave already done all the apt-get updates, etc and the FW update etc, so all that is done.
Please advise, about the next steps with this SD card process or maybe what I am missing.

thanks.


#53

Great, thanks for the info! Much clearer exactly where you need help now.

From the brewpi page in portainer there should be a >_ Console button.

brewpi_portainer

Click it. Then click the “Connect” button on the next page. You now have terminal open that’s currently in the home folder where all the brewpi files live. You can type ls to list the files and folders (folders are those without extensions).

root@c58bfe7a3eaf:/home/brewpi# ls
BEERSOCKET         BrewPiUtil.pyc       autoSerial.pyc        brewpiVersion.py     expandLogMessage.pyc      programController.py    tests
BrewPiProcess.py   LogMessages.h        backgroundserial.py   brewpiVersion.pyc    logs                  programController.pyc   utils
BrewPiProcess.pyc  MigrateSettings.py   backgroundserial.pyc  brewpi_dontrun       parseEnum.py          settings
BrewPiSocket.py    MigrateSettings.pyc  brewpi.py             check-running.sh     parseEnum.pyc         start.bat
BrewPiSocket.pyc   README.md            brewpiJson.py         data                 pinList.py            temperatureProfile.py
BrewPiUtil.py      autoSerial.py        brewpiJson.pyc        expandLogMessage.py  pinList.pyc           temperatureProfile.pycs

You’ll see the settings folder is here. You can change to it with cd settings and list the contents again with ls.

root@c58bfe7a3eaf:/home/brewpi# cd settings
root@c58bfe7a3eaf:/home/brewpi/settings# ls
config.cfg  config.cfg.example  defaults.cfg  tempProfile.csv

You want to edit config.cfg. For reasons that aren’t apparent to me, before doing so, you need to type export TERM=xterm (to get access to some standard terminal commands–including a text editor).

root@c58bfe7a3eaf:/home/brewpi/settings# export TERM=xterm
root@c58bfe7a3eaf:/home/brewpi/settings# nano config.cfg

Then, using nano (a simple text editor) you can edit the “port” line as described in the wiki. Press ctrl-O and then Enter to save, then ctrl-X to exit. The brewpi web interface should now should the script running (which means the pi can connect to the spark.

You could also find this file directly on the pi and edit it through ssh or by hooking up a keyboard and monitor directly to the pi, but in my mind at least the portainer route is more convenient even if it requires the weird TERM=xterm workaround.

Hope this helps!


#54

Ok so @adempewolff & @Elco I think I am stuck with step 6 of this. I have my Portainer Page up, and I also downloaded the iOS “Particle” App. I have the Pi and the Spark connected via USB and I already used the CMD to add the --device part. at the end but I have this error:
50
and the Particle App process does not show any Wifi networks.
I would like the option to connect to the spark either wifi or USB. In either case I still can NOT access the Brewpi webpage using the port/socket of 6666
SO right now I have:
scriptPath = /home/brewpi
wwwPath = /var/www/html
port = auto
port = socket://10.0.1.30:6666
altport = /dev/ttyACM0
boardType = p1
beerName = My First BrewPi Run
interval = 60.0
dataLogging = active
pi@raspberrypi:~/brewpi-data/settings $
But when I put in that IP nothing happens.

The logs from the Portainer show:
/entrypoint.sh: 40: exec: --device=/dev/ttyACM0:/dev/ttyACM0: not found

I hope this is helpful - please advise :slight_smile:

FYI I followed the directions (to get it to work) from these places:



and the latter part of this:
https://wiki.brewpi.com/getting-started/raspberry-pi-docker-install
And now I was trying to use this part:
https://wiki.brewpi.com/how-to-setup-wifi-on-the-brewpi-spark


#55

I’m not sure if you can currently configure brewpi to use both Wifi and USB at the same time but Elco can correct me if I’m wrong. My understanding is that you either need to use USB and add the --device=/dev/ttyACM0:/dev/ttyACM0 parameter when you deploy the brewpi docker container or use WIFI and change port = auto to port = socket://192.168.1.96:6666 in the /home/brewpi/settings/config.cfg file. I don’t think you can define two ports in the config file as you have done.

For the USB configuration, the docker deploy command will then be docker run -d --name brewpi -p 80:80 -v ~/brewpi-data:/data -v /etc/timezone:/etc/timezone -v /etc/localtime:/etc/localtime --restart always --device=/dev/ttyACM0:/dev/ttyACM0 brewpi/brewpi-raspbian. Critically, this command needs to be run on the pi itself (ie. by sshing into the Hypriot or Rasbian OS), not by using portrainer to open a command prompt within the brewpi container. I think you are trying to run this command from within a brewpi container that has already been deployed.


#56

Correct, you should use either

port = auto

for USB or

port = socket://<your-spark-ip>:6666

for WiFi.

You cannot have multiple port definitions.

I am working on updating the brewpi docker image to the latest version now, so I recommend waiting a day until it is updated.


#57

I’ve been using the BREWPI SPARK V2 on a Raspi 2 for the past few years. I’ve been wanting to convert to Docker. I’ve setup other containers for various other projects but I’m having trouble with this.

I’ve got the Sparkv2 hooked up to a converter to go from USB to Ethernet, is this Ok?
This is what my script is to build the container: sudo docker run -d --name brewpi -p 83:80 -v /volume1/docker/brewpi:/data --restart always --device=/dev/ttyACM0:/dev/ttyACM0 brewpi/brewpi-ubuntu. It will run and I see the test page but I don’t see any files in the /docker/brewpi folder for any additional configurations. Is this the best place to look?

Thanks,
Joel


#58

I successfully set up Brewpi in Docker on my Synology NAS. I set up port forwarding, so that the Brewpi webpage is accessible through a personal URL. I can see the unsecured webpage from anywhere, but so can anyone else. There is a secured webpage which I also port forwarded, but when I try to see that page, it asks for a user and password. I tried every likely possible pairing I could think of, and looked at the documentation for a default user and pass, but couldn’t find one. I would like to shut down the unsecured webpage, and only have the secured one be available on the web, but I need the user and password for it to be useful. Any advice on what the user and pass might be?


#59

Hi,

Sorry, I haven’t updated the docs for the password protected port. This is new in the latest version of the container. Nice that you have spotted it.

The latest version of the container exposes two ports:
port 80 for use on your internal network, without password.
port 81 for forwarding on your router, with password.

The default user is brewer and password brewpi.
You can change that by running this command in the container (replace brewer and brewpi with your desired user/pass):

htpasswd -bc /data/settings/brewpi.htpasswd brewer brewpi

#60

Still unable to resolve this…

LCD functions, graphs, lists of brews, logs… all broken.
Script is running on the back-end and can see my brewpi device, as all sensors show up with values in the maintenance panel.

I get that the do_not_run_brewpi file really shouldn’t be there when I click the start script button after nothing has happened in the UI… (even though $python brewpi.py --status shows things are running already).

The log file issues are dubious though.

The web scripts can’t seem to get to the back-end scripts/services properly in all cases.

I see logs…

#61

Those errors should not be there in the latest version of the docker image.
Did you pull recently and recreated the container? I pushed updates yesterday. (docker pull brewpi/brewpi-ubuntu)

Did you refresh your browser with ctrl-F5 to clear old cached pages?
Does it work in incognito mode?

For the log file issue:
Where do you map the brewpi data on the synology host? Is that data writable by docker?
