Features of HypriotOS Latest Docker Engine 19.03.0 Community Edition You can use the latest features of the freshly-baked Docker Engine 19.03.0 that is still warm. It includes the Swarm Mode, which allows high availability of services in a multi-node cluster within just a few simple commands. Up to date with Raspbian Lite Buster You can run HypriotOS with an up-to-date OS and Linux kernel which is in sync with the current Raspbian Lite Buster running a Linux kernel 4.19.58. Support for the complete Raspberry Pi family You can run HypriotOS on every model of the Raspberry Pi family - we're supporting Pi 1, 2, 3, the 3 B+, Zero and even the Compute Module and the new Raspberry Pi 4 B. Easy flashing and configuration We improved our flash tool, which puts HypriotOS onto a SD card that is ready to boot from with a single command. With additional command line options you can customize HypriotOS during the flash operation to have the best out-of-the-box first-boot experience. HypriotOS includes cloud-init, which makes the first boot of your Raspberry Pi customizable and you even are able connecting it to your Wi-Fi network during boot. After booting, you can find the Raspberry Pi at your network with a simple ping black-pearl.local - no more searching for IP addresses required thanks to the integrated Avahi service discovery. Enhanced security out of the box We think that security should be shipped out-of-the-box. We make HypriotOS more secure without you even noticing it. For instance, there is no built-in "root" user. Also, the default user "pirate" (password "hypriot") is can be customized or removed before the first boot. Just look at the file /boot/user-data. You can add your public SSH key, disable password logins and specify a different user account before you even boot your Raspberry Pi. WiFi can be customized and enabled to have Docker up an ## DockerCon 2017 Demo: Monitoring Docker Swarm with LED's DevFeed: [DockerCon 2017 Demo: Monitoring Docker Swarm with LED's]() Original publisher: [Read original article]() Published: 2017-04-20T20:30:34Z Content type: tutorial Language: en Sources: [Hypriot]() Topics: [Docker](), [Raspberry Pi](), [Docker Image](), [Containers](), [Linux]() Tags: [arm](), [docker](), [docker-hub](), [led](), [monitoring](), [multi-arch](), [raspberry-pi](), [rolling-update](), [swarm]() ### AI overview A DockerCon 2017 demonstration shows how to monitor Docker Swarm scaling and rolling updates with LEDs on a Raspberry Pi or UP board cluster. The article explains the required multi-architecture Docker images, swarm setup, LED monitor service, scaling commands, and rolling update visualization. ### Source excerpt At DockerCon 2017 in Austin I gave a presentation of a Raspberry Pi cluster mixed with some UP boards. The audience really liked the visual effects of the Docker Swarm scaling a service up and down. So I show you some background details what you need to run that demo on your Raspberry Pi cluster as well. All the effort played off to build that cluster, to find out how to drive LED's in swarm mode, to put it into my bag and go through customs on my flight from Germany to Austin, Texas. It really was fun to show this the audience and everybody liked it. To enable you to replay the demo with some Pimoroni Blinkt! LED's and Raspberry Pi - regardless if you only have Pi Zeros I want to show you the Docker images I used and the commands to show the scaling demo. The Docker image stefanscherer/monitor is available on the Docker Hub. It is a multi-architecture image that can be used on Linux with Intel or ARM CPU's. So just create a Docker swarm with the usual commands docker swarm init and then join some other workers with the swarm token shown in your terminal. Start the LED monitor First we have to start the LED monitor as a service so that it is running on each node of the Docker swarm. The option --mode global will do this and start one instance on each node. We have to bind mount both the Docker socket and a part of the file system into the container so it can access the /sys/class/fs file system. docker service create --name monitor --mode global \ --restart-condition any --mount type=bind,src=/sys,dst=/sys \ --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \ stefanscherer/monitor:1.1.0 Now we are all set to play with scaling an example service. Scale up There is another multi-arch image that I used for the scaling demo. It is the "whoami" web service that responds the container's hostname. First we create the service with docker service create --name whoami stefanscherer/whoami:1.1.0 As said this works with any Raspberry Pi or the UP board that ha ## Running Docker Swarm inside LXC (outdated) DevFeed: [Running Docker Swarm inside LXC (outdated)]() Original publisher: [Read original article]() Author: andreacorbellini Published: 2016-04-13T18:00:00Z Content type: tutorial Language: en Sources: [Andrea Corbellini]() Topics: [Docker](), [Tutorial](), [Containers](), [Development](), [Security]() Tags: [apparmor](), [article](), [containers](), [distributed-computing](), [docker](), [information-technology](), [lxc](), [security](), [shell](), [swarm](), [ubuntu]() ### AI overview This outdated tutorial explains how to run legacy Docker Swarm inside LXC containers using a preferred setup with AppArmor disabled, Docker OverlayFS storage, and etcd discovery. It notes that newer Docker Swarm does not work in LXC as described. ### Source excerpt UPDATE: This article was written in 2016 and refers to a version of Docker Swarm that is now known as "legacy Swarm". The newer Docker Swarm won't work in LXC as described in this article. I've been using Docker Swarm inside LXC containers for a while now, and I thought that I could share my experience with you.
