Using RancherOS as host in docker-machine

RancherOS
1

Hey guys,

RancherOS supports integration with docker-machine since v0.3.0 according to their documentation, RancherOS and Docker Machine and RancherOS's is more comprehensive.

Are there any guidelines regarding this?

For example, RancherOS documentation claims that only rancher user is allowed, but docker-machine is able to create one for itself (docker).

What about persistence, is it enough to replace the default console with ubuntu-console or is it necessary to install RancherOS to the VDD?

Anybody tweaked any such installation?

sysinfo: 10.11.3/Docker Toolbox 1.10

Thanks in advance.

I’m doing this currently. It works great!

Here’s the script I use to create a machine:

#!/bin/bash

MACHINE_NAME=$1
MEMORY=$2

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

if [ -z "$MACHINE_NAME" ]; then
  echo 'machine name required'
  exit 1
fi

if [ -z "$MEMORY" ]; then
  MEMORY="2048"
fi

RANCHER_OS_VERSION=v0.4.3-rc3
RANCHER_OS_URL=https://github.com/rancher/os/releases/download/$RANCHER_OS_VERSION/rancheros.iso
RANCHER_OS_FILE=$DIR/cache/$RANCHER_OS_VERSION/rancheros.iso

mkdir -p $DIR/cache/$RANCHER_OS_VERSION

if [ ! -e $RANCHER_OS_FILE ]; then
  curl -L -o $DIR/cache/$RANCHER_OS_VERSION/rancheros.iso $RANCHER_OS_URL
fi

docker-machine create --driver=parallels --parallels-memory=$MEMORY --parallels-boot2docker-url $DIR/cache/$RANCHER_OS_VERSION/rancheros.iso $MACHINE_NAME

The autoformat container handles detecting the docker-machine env and setting up storage for the VM; no install needed. Also docker-machine does create a docker user and it seems to Just Work.
