Demonstar walkthrough wrap7/5/2023 Around 90 popular docker applications like jenkins etc. If you prefer Kubernetes and Helm? No problem. It helps you deploy and scale applications with click of a button, No more need to build docker or kubernetes for apps. RancherOS is an ultra-lightweight Linux distribution which enables you to boot Your containers in seconds as well as run Docker, Kubernetes and Rancher at *Scale in production* that too with High Availaibility options. For private cloud you may use RancherOS. **With Rancher Private & Hybrid Cloud Becomes Reality** This is amazing, both docker and kubernetes containers controlled by Rancher's UI and in any cloud (*even private*) - unlike AWS does only only Amazon and Kubernetes in GCE. You can *quickly dpeloy multiple Docker as well as Kubernetes* clusters *across clouds* with click of a button. Rancher is _**not a container orchestrator**_, it' a complete container management platform that includes everything you need to manage containers in production. () container managerment platform product can be used to manage contrainer using its web based dashboard and run clusters. () is begning of container orchestration, Rancher company also provide () **container management platform**. $ sudo chmod 755 /opt/rancher/bin/start.sh $ echo "sudo system-docker start busydash" | sudo tee -a /opt/rancher/bin/start.sh Restart using `sudo shutdown -r` command. To make the container survive during the reboots, you can create the /opt/rancher/bin/start.sh script, and add the Docker start line to launch the Docker at each startup. Once running you can see monitoring over IP adress in a browser at () Lets launch a RancherOS monitoring dashboard docker container by executing `sudo system-docker run -d -net=host -name busydash husseingalal/busydash`. Delete containers using `sudo system-docker rm -f. Run containers using `sudo system-docker run. Use conventional docker commands to execute containers replacing `docker` with `suck system-docker` like Use `q` key to come out of editor, in this case IP adress was `192.168.139.128`ģ. IP will be availaible against interface **eth0**. Find IP address of RancherOS using `/sbin/ifconfig | less` command. Also execute `sudo system-docker ps` to verify system-dockerĢ. First execute `docker run hello-world` inside OS with active internet to ensure that docker system is fine. Type `sudo system-docker ps` to verify that RancherOS default service as docker containers are running.ġ. Boot your virtual machine you'll be taken to shell of RancherOS. Make sure that network is configured to **Host-Only: A Private Network Shared with the Host** for this example Create a virtual machine named *RancherOS (圆4)* with suitable hardware, just remove hard disk and add converted `rancheros-aliyun.vmdk` in place of it and reboot. Expansion will be required to grow disk when docker images are pulled into it. **Make sure to convert it into an expandable disk**. Download virtual disk image for RancherOS named as `rancheros-aliyun.vhd` then use VHD to VMDK converter like () to convert this VHD into `rancheros-aliyun.vmdk`. In order to run it as virtual machine proceed as follows: ![]() So you can instead use RancherOS inside a Virtual Machine like VMWare workstation etc. But after reboot all docker containers will be gone. Each github release contains - `rancheros.iso` just when you want to boot from iso and keep working (*no install live disk*). This will take you to same github repo but right release. To get right release go to home page () and then click **Download Rancher OS**. Download RancherOS distribution from github repository (). Please refer to () for more understanding of sub-section A and Bġ. RancherOS uses `system-docker` to wrap `docker` so you've to use `sudo system-docker run. are not present so its would be tough to operate. Being thin linux only basic linux commands will only work like for IP checking use `/sbin/ifconfig | less`. It makes it simple to run containers at scale in development, test and production. RancherOS is very thin nothing else installed only busybox, system-docker and docker. () is an ultra-light (*around 69-100MB*) linux operating system dedicated to running docker containers.
