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:
