Bifrost Guide

Prep host

clone kolla-ansible

git clone https://github.com/openstack/kolla-ansible

cd kolla-ansible

set up kolla dependcies `doc`:quickstart.rst

fix hosts file

Docker bind mounts /etc/hosts into the container from a volume. This prevents atomic renames which will prevent ansible from fixing the /etc/hosts file automatically.

to enable bifrost to be bootstrapped correctly add the deployment hosts hostname to 127.0.0.1 line e.g.

ubuntu@bifrost:/repo/kolla$ cat /etc/hosts 127.0.0.1 bifrost localhost

# The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts 192.168.100.15 bifrost

enable source build type

via config file

tox -e genconfig

modify kolla-build.conf as follows.

set install_type to source

command line

alternitivly if you do not wish to use the kolla-build.conf you can enable a source build by appending -t source to your kolla-build or tools/build.py command.

build container

Development

tools/build.py bifrost-deploy

Production

kolla-build bifrost-deploy

Prepare bifrost configs

create servers.yml

the servers.yml will describing your physical nodes and list ipmi credentials. see bifrost dynamic inventory examples for mor details.

e.g. /etc/kolla/config/bifrost/servers.yml

---
cloud1:
    uuid: "31303735-3934-4247-3830-333132535336"
    driver_info:
      power:
        ipmi_username: "admin"
        ipmi_address: "192.168.1.30"
        ipmi_password: "root"
    nics:
      -
        mac: "1c:c1:de:1c:aa:53"
      -
        mac: "1c:c1:de:1c:aa:52"
    driver: "agent_ipmitool"
    ipv4_address: "192.168.1.10"
    properties:
      cpu_arch: "x86_64"
      ram: "24576"
      disk_size: "120"
      cpus: "16"
    name: "cloud1"

adjust as appropriate for your deployment

create bifrost.yml

By default kolla mostly use bifrosts default playbook values. Parameters passed to the bifrost install playbook can be overridden by creating a bifrost.yml file in the kolla custom config director or in a bifrost sub directory. e.g. /etc/kolla/config/bifrost/bifrost.yml

mysql_service_name: mysql ansible_python_interpreter: /var/lib/kolla/venv/bin/python network_interface: < add you network interface here > # uncomment below if needed # dhcp_pool_start: 192.168.2.200 # dhcp_pool_end: 192.168.2.250 # dhcp_lease_time: 12h # dhcp_static_mask: 255.255.255.0

Create Disk Image Builder Config

By default kolla mostly use bifrosts default playbook values when building the baremetal os image. The baremetal os image can be customised by creating a dib.yml file in the kolla custom config director or in a bifrost sub directory. e.g. /etc/kolla/config/bifrost/dib.yml

dib_os_element: ubuntu

Deploy Bifrost

ansible

Development

tools/kolla-ansible deploy-bifrost

Production

kolla-ansible deploy-bifrost

manual

Start Bifrost Container

docker run -it --net=host -v /dev:/dev -d --privileged --name bifrost_deploy 192.168.1.51:5000/kollaglue/ubuntu-source-bifrost-deploy:3.0.0

copy configs

docker exec -it bifrost_deploy mkdir /etc/bifrost
docker cp /etc/kolla/config/bifrost/servers.yml bifrost_deploy:/etc/bifrost/servers.yml
docker cp /etc/kolla/config/bifrost/bifrost.yml bifrost_deploy:/etc/bifrost/bifrost.yml
docker cp /etc/kolla/config/bifrost/dib.yml bifrost_deploy:/etc/bifrost/dib.yml

bootstrap bifrost

docker exec -it bifrost_deploy bash

generate ssh key

ssh-keygen

source env variables

cd /bifrost . env-vars . /opt/stack/ansible/hacking/env-setup cd playbooks/

bootstrap and start services

ansible-playbook -vvvv -i /bifrost/playbooks/inventory/localhost /bifrost/playbooks/install.yaml -e @/etc/bifrost/bifrost.yml

Check ironic is running

docker exec -it bifrost_deploy bash
cd /bifrost
. env-vars

Running "ironic node-list" should return with no nodes, e.g.

(bifrost-deploy)[root@bifrost bifrost]# ironic node-list
+------+------+---------------+-------------+--------------------+-------------+
| UUID | Name | Instance UUID | Power State | Provisioning State | Maintenance |
+------+------+---------------+-------------+--------------------+-------------+
+------+------+---------------+-------------+--------------------+-------------+

Enroll and Deploy Physical Nodes

ansible

Development

tools/kolla-ansible deploy-servers

Production

kolla-ansible deploy-servers

manual

docker exec -it bifrost_deploy bash
cd /bifrost
. env-vars
export BIFROST_INVENTORY_SOURCE=/etc/bifrost/servers.yml
ansible-playbook -vvvv -i inventory/bifrost_inventory.py enroll-dynamic.yaml -e "ansible_python_interpreter=/var/lib/kolla/venv/bin/python" -e network_interface=<provisioning interface>

docker exec -it bifrost_deploy bash
cd /bifrost
. env-vars
export BIFROST_INVENTORY_SOURCE=/etc/bifrost/servers.yml
ansible-playbook -vvvv -i inventory/bifrost_inventory.py deploy-dynamic.yaml -e "ansible_python_interpreter=/var/lib/kolla/venv/bin/python" -e network_interface=<prvisioning interface> -e @/etc/bifrost/dib.yml

At this point ironic should clean down your nodes and install the default os image.

Advanced configuration

Bring your own image

TODO

Bring your own ssh key

To use your own ssh key after you have generated the passwords.yml file update the private and public keys under bifrost_ssh_key.

Known issues

SSH deamon not running

By default sshd is installed in the image but may not be enabled. If you encounter this issue you will have to access the server phyically in recovery mode to enable the ssh service. If your hardware supports it, this can be done remotely with ipmitool and serial over lan. e.g.

ipmitool -I lanplus -H 192.168.1.30 -U admin -P root sol activate
