This is only needed in a clean hypervisor. If you have a laptop with a user with sudo then you can skip the user creation and sudo setup. As root:
useradd -s /bin/bash -d /home/gibi -m gibi
echo "gibi ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/gibi
sudo -u gibi -i
As your normal user:
sudo dnf install git ansible-core
git clone https://github.com/openstack-k8s-operators/install_yamls.git
cd install_yamls
cd devsetup
make download_tools
In some OS the go binary won't be in the users path check with go version
if you don't have go visible then add to ~/.bashrc
PATH="/usr/local/bin/:$PATH"
export PATH
Go to https://cloud.redhat.com/openshift/create/local and download the pull
secret and put it to ~/pull-secret.txt
CRC is OCP in a single VM. You might be able to use a bit less memory and disk but these values known to be enough
PULL_SECRET=~/pull-secret.txt CPUS=6 MEMORY=24576 DISK=100 make crc
This will take a while, go get coffee
eval $(crc oc-env)
oc login -u kubeadmin https://api.crc.testing:6443
oc get nodes
make crc_attach_default_interface
cd ~/install_yamls/
make crc_storage
make openstack_wait
This will take a while. You can follow the progress in another terminal with
oc get pods -n openstack-operators --watch
make openstack_wait_deploy
The execution time varies and the make target might time out with
error: timed out waiting for the condition on openstackcontrolplanes/openstack-galera-network-isolation Then don't worry you can continue waiting
with
oc kustomize /home/gibi/install_yamls/out/openstack/openstack/cr | oc wait --for condition=Ready --timeout=300s -f -
You can follow the progress in another terminal
oc get pods -n openstack --watch
cd ~/install_yamls/devsetup
EDPM_TOTAL_NODES=1 make edpm_compute
If you have enough RAM you can deploy more than one compute. 4G RAM per compute is needed
cd ~/install_yamls
TIMEOUT=600s DATAPLANE_TOTAL_NODES=1 make edpm_wait_deploy
You can see the progress on ansible role level with
oc get pods -n openstack --watch
Or you can look at the ansible execution logs with
while true; do oc logs -n openstack -f `oc get pods -n openstack | grep 'openstack-edpm-' | grep Running| cut -d ' ' -f1` 2>/dev/null || echo -n .; sleep 1; done
The deploy might also time out, you can wait more with
oc kustomize /home/gibi/install_yamls/out/openstack/dataplane/cr | oc wait --for condition=Ready --timeout=20m -f -
If you needed to wait more to succeed then you need to run the following as well
make edpm_nova_discover_hosts
You can see your compute node and the openshift VM with
sudo virsh list --all
You can interact with the control plane via the OpenStackControlPlane CR
oc get OpenStackControlPlane -o yaml
You can interact with the data plane via the OpenStackDataPlaneNodeSet and OpenStackDataPlaneDeployment CRs
oc get OpenStackDataPlaneNodeSet -o yaml
oc get OpenStackDataPlaneDeployment -o yaml
You can interact with the openstack APIs via the openstackclient pod
oc exec -t openstackclient openstack compute service list
You can ssh into your compute node
ssh root@192.168.122.100
If you deployed more computes then the next is .101 etc. You can get the ssh key for the computes with
oc get secret/dataplane-ansible-ssh-private-key-secret -o go-template --template '{{index .data "ssh-privatekey"}}' | base64 --decode
If you need to retry the whole deployment then destroy the env with
crc delete
cd ~/install_yamls/devsetup
EDPM_TOTAL_NODES=1 make edpm_compute_cleanup
and then go back to the CRC step.
