Here's how to create a provisioning node to run deploy-tools (this came up with NDS-395)

• In Nebula, create instance, select CoreOSStable1122
• Disable updates

  • sudo systemctl stop update-engine

  • sudo systemctl stop locksmithd

• Fix the Docker BIP and MTU
• sudo su
  • mkdir -p /etc/systemd/system/docker.service.d
  • vi /etc/systemd/system/docker.service.d/10-docker0.conf

[Service]
Environment="DOCKER_OPT_BIP=--bip=172.30.0.1/16"
Environment="DOCKER_OPT_MTU=--mtu=1454"

• systemctl daemon-reload
• systemctl restart docker
• cd /var/lib/kubelet/pods && rm -rf *

To fix single-node installations

 Multi-node deployment via Ansible currently sets this for you, but for single-node installations, thisi s a manual step:

# Elevate to a superuser shell
sudo su

# Create a systemd drop-in to set the Docker MTU
mkdir -p /etc/systemd/system/docker.service.d/
bash -c "echo '[Service]
Environment="DOCKER_OPT_MTU=--mtu=1454"' > /etc/systemd/system/docker.service.d/10-docker0.conf"

# Then reload / restart your Docker daemon
systemctl stop docker
systemctl daemon-reload
systemctl start docker

Adding image to OpenStack

If the image doesn't exist in the current OpenStack project:

• docker run -it ndslabs/deploy-tools bash
• curl https://stable.release.core-os.net/amd64-usr/current/coreos_production_openstack_image.img.bz2 -o coreos_production_openstack_image.img.bz2
• bunzip coreos_production_openstack_image.img.bz2
• openstack image create --disk-format qcow2 --file ./coreos_production_openstack_image.img CoreOSStable1122
