    @oizone we have the same problem: we are an open source informatic school in limbe (cameroon), we are using and testing docker and docker-compose for some apllications, but we could not install kubernetes succesfully. we follow the
    https://blog.hypriot.com/post/setup-kubernetes-raspberry-pi-cluster/ but it fails by kubeadm init --pod-network-cidr 10.244.0.0/16 any idea?

    @michelcameroon use k3s instead, it's full kubernetes but built for raspberry pi as a first class citizen
    Ross Beazley
    @rossbeazley
    @oizone I recommend k3s over k8s

    Not sure if it's a feature or a bug and if so with which component: https://serverfault.com/questions/1006028/ntp-time-sync-failures-on-debian

    Hi everyone!
    I just installed HypriotOS on my Raspberry PI.
    Unfortunately, I am unable to connect with the default password, while I can ping the raspberry.
    Is it a known issue?

    Hi folks. Just installed the latest image on my Pi. It is running and I can access it. I thought that it would include a ton of docker images/containers. It does not seem to have anything other than raspian running docker. Am I missing something?

    Hi everybody, I wonder if there is some French speaker here interested by talking about HypriotOS in a French podcast? If so, don't hesitate to send me a DM on Twitter @Saphoooo

    Hi! So first of all, I've installed HypriotOS yesterday and was impressed how easy it was, thank you for all that work! :) Now I seem to be stuck with a network issue with docker stack, though. I can run docker run -d -p 4000:80 hypriot/rpi-busybox-httpd on the Pi and then successfully use curl http://kurt.local:4000/ from another machine. However, if I try to deploy the same image in a stack using https://gist.github.com/witsch/f0543088b41e3c2b94eac6e20aaad13c and docker stack deploy -c hello.yaml hello I'm getting "no suitable node (unsupported platform on 1 node)". And even more strange is a "pihole" deployment that does work using docker stack, i.e. I can curl http://10.0.0.25/admin/ from the Pi, but get a timeout when trying the same from another machine. Does any of you have an idea what I might be doing wrong? :)
    Andreas Zeidler
    @witsch
    Ah, okay. Now that I wrote it down I found the solution for one of the issues, of course! :) So when I run docker stack deploy --resolve-image=never -c hello.yaml hello I can use curl http://10.0.0.25:4000/ from the Pi, but not from the "outside"…

    Hmm, when comparing the iptables for run and stack it seems there's a masquerading rule missing. And iptables --table nat -A POSTROUTING -d 172.18.0.2/32 -p tcp -m tcp --dport 4000 -j MASQUERADE indeed fixes the issue. I'm not sure that's the right thing to do, though.

    Ok, the problem was the default swarm address pool was conflicting with my local network… %)
    Running docker swarm init --default-addr-pool 10.20.0.0/16 --default-addr-pool-mask-length 24 fixed things… have a good night!

    Has anyone gotten LUKS disk encryption to work on the hypriot image? I keep getting "cryptsetup: cryptsetup failed, bad password or options?".

    I am setting up kubernetes on 2 rpi's running hypriot. I can make the cluster and I see both nodes. Does anyone have any experience with using ROS in this env? I have tried the various setups found on the web but nothing seems to work. My main issue is getting roscore ( in a docker container) talking to another ROS talker/listener containers. Any help is approeciated

    Hi,
    I have a couple of RPi 2's and would like to use Docker on them.
    Can I use Hypriot ? I see that was "promised" a (long) while ago.

    after installing master i try to install worker with sudo k3s agent --server https://myserver:6443 --token ${NODE_TOKEN}
    they not appear with get node i see that the token file has server and not node like i see in some docu. if i check the worker with sudo k3s kubectl get node they appear as master, some idea?
    @michelcameroon
    with this command i could manage one worker
    curl -sfL https://get.k3s.io | K3S_URL=https://192.168.1.8:6443 K3S_TOKEN=K1056a31fc457716b4b41f372ec20c183584a4bfcea69db7ed88903b3355125351b::server:0581527deec67c7939e3d8ef501f4b96 sh -
    but when get node i recieve master but the "worker" has no role, is ti normal?
    Ross Beazley
    @rossbeazley
    @michelcameroon the workers don't need a role, sounds like you have a working setup
    To see all the pods currently running across the cluster type something like
    kubectl get pods --allnamespaces -o wide
    It might be --all-namespaces
    michel
    @michelcameroon
    thanks get pods i get i think all helm metrics local svclb coredns traefik svclb on knode now i try to make a second node (worker) with the command sudo k3s agent --server https://myserver:6443 --token ${NODE_TOKEN} it dos not work now i try with curl -sfL https://get.k3s.io | K3S_URL=https://192.168.1.8:6443 K3S_TOKEN=K1056a31fc457716b4b41f372ec20c183584a4bfcea69db7ed88903b3355125351b::server:0581527deec67c7939e3d8ef501f4b96 sh -
    i will tell if it is not working
    michel
    @michelcameroon
    ok i have now 1 master and 2 nodes
    michel
    @michelcameroon
    hi @wilsonianb thanks for your reply, i have the same result but i wonder if you try the command of the k3s startpage sudo k3s agent --server https://myserver:6443 --token ${NODE_TOKEN} for me it was not working

    I am getting an error after doing docker swarm init on my hypriot system v1.12.x the following is what I am seeing:

    $ docker node ls
    Error response from daemon: This node is not a swarm manager. Use "docker swarm init" or "docker swarm join" to connect this node to swarm and try again.
    HypriotOS/armv7: pirate@cfDOC6 in ~
    $ docker swarm init
    Error response from daemon: This node is already part of a swarm. Use "docker swarm leave" to leave this swarm and join another one.

    Then I leave the swarm recreat it and the same thing all over again. Anyone have any ideas?

    Hello,
    I can't manage do the user-data file working on cloud-init.

    I'm using a Raspberry Pi 3B+, and flashing the OS with Etcher on Win10. When I do the flash without any change on the boot, it work as needed via eth0, ssh working as well. I managed to use the wifi connection manualy too.

    When I just change the username setting in the user-data file, it works too, with the new username.

    But when I unquote some line (for exemple : # Install any additional apt packages you need here
    packages:

    • ntp)
      Or just the wifi setting part, it doesn't work.

    1) the wifi doesn't manage to connect my router at all
    2) when I try ssh, the default password (unchanged) doesn't work. (access denied)

    I walk around for quite a bit all around the github issues and the internet but it is very frustating so far.

    Hope an rescue here.

    Thanks a lot.

    @Mlynarc
    I (finaly) managed to solve my issue after a long read on the cloud-init doc.
    Mlynarc
    @Mlynarc

    It may help for others :

    When I changed the user-data config file, I just deleted the # and it stayed a space before the cloud-init modules name.

    Correcting the YAML syntax solved obviously the problem but it wasn't clear at my eye at first.
    I thought I had just to uncomment the lines I need to use.

    Thank you for the work done.

    Hi folks, I've already updated to python3.8 on my Jetson Nano, but now docker-compose seems broken and I couldn't reinstall it successfully like yesterday. Is there a way to overcome this issue? :(

    Hello, I Have a question. During boot I have custom user-data file and edit with package_update and package_upgrade to true value. but I think the RPI doessnt execute this. I We must define a special configuration so that the rpi is connected to the web during boot ?

    Hi. I'm building a custom SD image (with image-builder-rpi) but my /boot partition is empty after the process. Any idea what could cause it?
    Arjen Verstoep
    @Terr
    And is there a way to speed up subsequent builds? Every attempt is taking so much time :P
    Arjen Verstoep
    @Terr
    Alright, running the process again fixed the /boot issue (I guess there was an error during the build script somewhere. But is there a way to speed things up?: )

    newbie here .. hypriot blog says a new version was just announced .. download link sent along a v1.11.0 version file. However, a week or so ago I had downloaded a v1.12.0 file, which, extracted, is dated January 7. The version number is higher but it is older? I'm confused.

    Hi, I wanted to use OpenMax for HW acceleration on my pi 4. Now I noticed that the devices (/dev/vcsm and /dev/vchiq) that normally come on a standard install with raspbian or even arch arm are missing. Has anyone had a similar issue? How can I get them if they are not there by default? thanks :)
