k8s yaml generator/installer for Cloud Native OpenStack

The main purpose is to provide scripts to automate installing OpenStack in your pre-installed OpenShift environment.

Aside from generating Yaml and running oc commands to apply them to your cluster nothing in this repo should modify the local machine, require sudo, or make any changes to the local machine.

Helper scripts to automate installing CRC and required tools with versions used in openstack-k8s-operators can be found in devsetup. These scripts/playbook require sudo permissions.

Note The install_yamls project expects several dependencies on the host machine. Without them the deployment will fail and you will have install them first. In general terms, all tools required by Openshift are also required by install_yamls. Most importanly, the kubectl must be present on the system.

Goals

  1. WIP: Support installing individual operators for fast testing iteration

  2. TODO: Support installing the combined Openstack umbrella operator

Example using your preinstalled CRC (Code Ready Containers) Environment

Similar commands should work in any OCP environment though.

# set your CRC ENV variables and PATH for 'oc'
eval $(crc oc-env)

# one time operation to initialize PVs within the CRC VM
make crc_storage

# Install MariaDB Operator using OLM (defaults to quay.io/openstack-k8s-operators)
make mariadb MARIADB_IMG=quay.io/openstack-k8s-operators/mariadb-operator-index:latest

# Install Keystone Operator using OLM (defaults to quay.io/openstack-k8s-operators)
make keystone KEYSTONE_IMG=quay.io/openstack-k8s-operators/keystone-operator-index:latest

Deploy example CRs

# Deploy MariaDB
make mariadb_deploy

# Deploy Keystone
make keystone_deploy

Deploy dev env using CRC, edpm nodes with isolated networks

Warning The dev environment requires substantial resources to be deployed successfully. It is recommended that you deploy this environment on machines with enough overhead.

  • clone install_yamls
git clone https://github.com/openstack-k8s-operators/install_yamls.git
  • ensure the dependencies are installed
cd install_yamls/devsetup
make download_tools
  • install CRC
cd install_yamls/devsetup
CPUS=12 MEMORY=25600 DISK=100 make crc
  • login to OCP
eval $(crc oc-env)
oc login -u kubeadmin -p 12345678 https://api.crc.testing:6443
  • attach libvirt default network to the crc (default IP 192.168.122.10). This network is used as a vlan trunk to isolate the networks using vlans.
make crc_attach_default_interface
  • create edpm nodes
EDPM_TOTAL_NODES=2 make edpm_compute
  • create dependencies
cd ..
make crc_storage
make input
  • install openstack-operator either from quay.io or the redhat-marketplace

install using the latest openstack-operator-index from quay.io

make openstack

install using the redhat-marketplace

REDHAT_OPERATORS=true make openstack

Note this will also run the openstack_prep target, which if NETWORK_ISOLATION == true will install nmstate and metallb operator, configure the secondary interface of the crc VM via nncp, creates the network-attachment-definitions for datacentre, internalapi, storage and tenant network. Also the metallb l2advertisement and the ipaddresspools get created.

The following NADs with ip ranges get configured:

internalapi: 172.17.0.30-172.17.0.70
storage:     172.18.0.30-172.18.0.70
tenant:      172.19.0.30-172.19.0.70

The following IPAddressPools with ip ranges get configured:

internalapi: 172.17.0.80-172.17.0.90
storage:     172.18.0.80-172.18.0.90
tenant:      172.19.0.80-172.19.0.90
  • (optional) deploy ceph container using storage network
HOSTNETWORK=false NETWORKS_ANNOTATION=\'[\{\"name\":\"storage\",\"namespace\":\"openstack\"\}]\' MON_IP=172.18.0.30 make ceph TIMEOUT=90

Note as it is the first pod requesting an ip using the storage network, it will get the first IP from the configured range in the whereabouts ipam pool, which is 172.18.0.30 .

  • deploy the ctlplane

If NETWORK_ISOLATION == true, config/samples/core_v1beta1_openstackcontrolplane_network_isolation.yaml will be used, if false then config/samples/core_v1beta1_openstackcontrolplane.yaml.

make openstack_deploy

(optional) To deploy with ceph as backend for glance and cinder, a sample config can be found at https://github.com/openstack-k8s-operators/openstack-operator/blob/main/config/samples/core_v1beta1_openstackcontrolplane_network_isolation_ceph.yaml .

Note Make sure to replace the _FSID_ in the sample with the one from the ceph cluster. When deployed with make ceph

curl -o /tmp/core_v1beta1_openstackcontrolplane_network_isolation_ceph.yaml https://raw.githubusercontent.com/openstack-k8s-operators/openstack-operator/main/config/samples/core_v1beta1_openstackcontrolplane_network_isolation_ceph.yaml
FSID=$(oc get secret ceph-conf-files -o json | jq -r '.data."ceph.conf"' | base64 -d | grep fsid | sed -e 's/fsid = //') && echo $FSID
sed -i "s/_FSID_/${FSID}/" /tmp/core_v1beta1_openstackcontrolplane_network_isolation_ceph.yaml
oc apply -f /tmp/core_v1beta1_openstackcontrolplane_network_isolation_ceph.yaml

Wait for the ctlplane to be up.

At this point the ctlplane is deployed with the services using isolated networks as specified in the CR sample.

Note Deployment may take longer than the default timeout allows for. In these cases, make sure to adjust DATAPLANE_TIMEOUT variable.

  • deploy edpm compute
# To use a NTP server other than the ntp.pool.org default one, override the DATAPLANE_NTP_SERVER variable
DATAPLANE_TOTAL_NODES=2 make edpm_wait_deploy

Note: if you used the edpm_deploy target to start the deployment then after the compute services are visible in openstack compute service list you need to manually run host discovery:

make edpm_nova_discover_hosts
  • wait until finished, then can check the env
oc -n openstack rsh openstackclient
openstack compute service list
