Manual Update of CoreOS

Goal

To create kubernetes multi nodes environments on Windows, one of the option is to create a cluster using CoreOS since the foot print is quite reduced.

Setup of the cluster

TBD

Update of the cluster

I found the following link

sudo bash -c 'mkdir -p /etc/systemd/system/docker.service.d/; cat <<EOF > /etc/systemd/system/docker.service.d/50-insecure-registry.conf
[Service]
Environment="DOCKER_OPTS=--insecure-registry 10.0.0.0/8 --insecure-registry 172.16.0.0/12 --insecure-registry 192.168.0.0/16"
EOF
'

sudo bash -ec 'uname -a && cat /etc/lsb-release && \
echo GROUP=stable > /etc/coreos/update.conf && \
systemctl unmask update-engine.service && \
systemctl start update-engine.service && \
update_engine_client -update && \
reboot'

sudo journalctl -u update-engine.service | grep "boot flags"

sudo bash -ec 'systemctl stop update-engine.service && \
systemctl mask update-engine.service'
