Test-Infra

This project deploys the OpenShift Assisted Installer in Minikube and spawns libvirt VMs that represent bare metal hosts.

Prerequisites

  • CentOS 8 or RHEL 8 host
  • File system that supports d_type
  • Ideally on a bare metal host with at least 64G of RAM.
  • Run as a user with passwordless sudo access or be ready to enter sudo password for prepare phase.
  • Get a valid pull secret (JSON string) from redhat.com if you want to test the installation (not needed for testing only the discovery flow). Export it as
export PULL_SECRET='<pull secret JSON>'

Instructions

Host preparation

On the bare metal host:

dnf install -y git make
cd /home/test # don't do it on /root it will breaks build image mounts and fail to run
git clone https://github.com/tsorya/test-infra.git

When using this infra for the first time on a host, run:

make create_full_environment

This will install required packages, configure libvirt, pull relevant Docker images, and start Minikube.

Usage

There are different options to use test-infra, which can be found in the makefile.

Full flow cases

The following is a list of stages that will be run:

  1. Start Minikube if not started yet
  2. Deploy services for assisted deployment on Minikube
  3. Create cluster in bm-inventory service
  4. Download ISO image
  5. Spawn required number of VMs from downloaded ISO with parameters that can be configured by OS env (check makefile)
  6. Wait until nodes are up and registered in bm-inventory
  7. Set nodes roles in bm-inventory by matching VM names (worker/master)
  8. Verify all nodes have required hardware to start installation
  9. Install nodes
  10. Download kubeconfig-noingress to build/kubeconfig
  11. Waiting till nodes are in "installed" state, while verifying that they don't move to "error" state
  12. Verifying cluster is in state "installed"
  13. Download kubeconfig to build/kubeconfig

Note: Please make sure no previous cluster is running before running a new one (it will rewrite its build files).

Run full flow with install

To run the full flow, including installation:

make run_full_flow_with_install

Or to run it together with create_full_environment (requires sudo password):

make all

Run full flow without install

To run the flow without the installation stage:

make run_full_flow

Run only deploy nodes (without pre deploy of all assisted service)

make deploy_nodes or make deploy_nodes_with_install

Redeploy nodes

make redeploy_nodes or make redeploy_nodes_with_install

Redeploy with assisted services

make redeploy_all or make redeploy_all_with_install

Cleaning

Cleaning test-infra environment.

Clean all include minikube

make destroy

Clean nodes only

make destroy_nodes

Delete all virsh resources

Sometimes you may need to delete all libvirt resources

make delete_all_virsh_resources

Install cluster

Install cluster after nodes were deployed. Can take ClusterId as os env

make install_cluster

Create cluster and download ISO

make download_iso

deploy_bm_inventory and Create cluster and download ISO

make download_iso_for_remote_use

start_minikube and Deploy UI and and open port forwarding on port 6008, allows to connect to it from browser

make deploy_ui

Kill all open port forwarding commands, will be part of destroy target

make kill_all_port_forwardings

OS parameters used for configurations

BMI_BRANCH          bm-inventory branch to use, default: master
IMAGE               path to ISO to spawn VM with, if set vms will be spawn with this iso without creating cluster

NETWORK_BRIDGE      network bridge to use while creating virsh network, default: tt0
OPENSHIFT_VERSION   OpenShift version to install, default: "4.4"
PROXY_URL:          proxy URL that will be pass to live cd image
INVENTORY_URL:      update bm-inventory config map INVENTORY_URL param with given URL
INVENTORY_PORT:     update bm-inventory config map INVENTORY_PORT with given port
AGENT_DOCKER_IMAGE: agent docker image to use, will update bm-inventory config map with given value
INSTALLER_IMAGE:    assisted-installer image to use, will update bm-inventory config map with given value
SERVICE:            bm-inventory image to use
DEPLOY_TAG:         the tag to be used for all images (bm-inventory, assisted-installer, agent, etc) this will override any other os params

Test bm-inventory image

make redeploy_all SERVICE=<image to test>
or 
export PULL_SECRET='<pull secret JSON>'; make redeploy_all_with_install SERVICE=<image to test>

Test agent image

make redeploy_all AGENT_DOCKER_IMAGE=<image to test> 
or
make redeploy_all_with_install AGENT_DOCKER_IMAGE=<image to test>

Test installer image

make redeploy_all INSTALLER_IMAGE=<image to test> 
or
export PULL_SECRET='<pull secret JSON>'; make redeploy_all_with_install INSTALLER_IMAGE=<image to test>

Test installer, bm-inventory and agent images in the same flow

make redeploy_all INSTALLER_IMAGE=<image to test> AGENT_DOCKER_IMAGE=<image to test> SERVICE=<image to test>
or 
export PULL_SECRET='<pull secret JSON>'; make redeploy_all_with_install INSTALLER_IMAGE=<image to test> AGENT_DOCKER_IMAGE=<image to test>  SERVICE=<image to test>

Test infra image

Create and push new image will create new bm-inventory client, build new image and push image

make build_and_push_image IMAGE_NAME=<your full image path> IMAGE_TAG=<default is latest>

Use new image, will pull image from hub, check that image is public, if tag is not latest update skipper YAML
