The smallest, easiest way to run Docker in production at scale. Everything in RancherOS is a container managed by Docker. This includes system services such as udev and rsyslog. RancherOS includes only the bare minimum amount of software needed to run Docker. This keeps the binary download of RancherOS very small. Everything else can be pulled in dynamically through Docker.
Everything in RancherOS is a Docker container. We accomplish this by launching two instances of Docker. One is what we call the system Docker which runs as the first process. System Docker then launches a container that runs the user Docker. The user Docker is then the instance that gets primarily used to create containers. We created this separation because it seemed logical and also it would really be bad if somebody did
docker rm -f $(docker ps -qa)and deleted the entire OS.
Note: 1. you can use
httpsin the above URLs, e.g. for iPXE. 2. you can use
v1.5.6in the above URLs if you want to get the latest version.
SSH keys are added to the
rancheruser, so you must log in using the rancher user.
Additionally, images are available with support for Amazon EC2 Container Service (ECS) here.
You can get RancherOS in the Azure Marketplace, currently only the
rancheruser can be logged in through SSH keys.
Please refer to our RancherOS Documentation website to read all about RancherOS. It has detailed information on how RancherOS works, getting-started and other details.
Please submit any RancherOS bugs, issues, and feature requests to rancher/os.
