assisted-service

Prerequisites

  1. Docker
  2. skipper https://github.com/stratoscale/skipper
  3. minikube (for tests)
  4. kubectl

First Setup

To push your build target to a Docker registry you first need to change the default target.

  1. Create a quay.io or Docker Hub account if you don't already have one. These instructions refer to quay.io, Docker Hub is similar.
  2. Create a repository called assisted-service.
  3. Make sure you have your ~/.docker/config.json file set up to point to your account. For quay.io, you can go to quay.io -> User Settings, and click "Generate Encrypted Password" under "Docker CLI Password".
  4. Login to quay.io using docker login quay.io.
  5. Export the SERVICE environment variable to your Docker registry, and pass a tag of your choice, e.g., "test":
export SERVICE=quay.io/<username>/assisted-service:<tag>

For the first build of the build container run:

skipper build assisted-service-build

Build

skipper make all

Generate code after swagger changes

After every change in the API (swagger.yaml) the code should be generated and the build must pass.

skipper make generate-from-swagger

Test

Pre-configuration

  • Run minikube on your system.
  • Deploy services skipper make deploy-test

Run system tests

skipper make test

Run system tests with regex

skipper make test FOCUS=versions

Run only unit tests

skipper make unit-test

Run unit tests for specific package

skipper make unit-test TEST=./internal/host

Update service for the subsystem tests

if you are making changes and don't want to deploy everything once again you can simply run this command:

skipper make update && kubectl get pod --namespace assisted-installer -o name | grep assisted-service | xargs kubectl delete --namespace assisted-installer

It will build and push a new image of the service to your Docker registry, then delete the service pod from minikube, the deployment will handle the update and pull the new image to start the service again.

Deployment

Deploy to minikube

The deployment is a system deployment, it contains all the components the service need for all the operations to work (if implemented). S3 service (scality), DB and will use the image generator to create the images in the deployed S3 and create relevant bucket in S3.

skipper make deploy-all

Deploy to OpenShift

Besides default minikube deployment, the service support deployment to OpenShift cluster using ingress as the access point to the service.

skipper make deploy-all TARGET=oc-ingress

This deployment option have multiple optional parameters that should be used in case you are not the Admin of the cluster:

  1. APPLY_NAMESPACE - True by default. Will try to deploy "assisted-installer" namespace, if you are not the Admin of the cluster or maybe you don't have permissions for this operation you may skip namespace deployment.
  2. INGRESS_DOMAIN - By default deployment script will try to get the domain prefix from OpenShift ingress controller. If you don't have access to it then you may specify the domain yourself. For example: apps.ocp.prod.psi.redhat.com

To set the parameters simply add them in the end of the command, for example

skipper make deploy-all TARGET=oc-ingress APPLY_NAMESPACE=False INGRESS_DOMAIN=apps.ocp.prod.psi.redhat.com

Note: All deployment configurations are under the deploy directory in case more detailed configuration is required.

Deploy UI

This service support optional UI deployment.

skipper make deploy-ui
  • In case you are using podman run the above command without skipper.

For OpenShift users, look at the service deployment options on OpenShift platform.

Deploy Monitoring

This will allow you to deploy Prometheus and Grafana already integrated with Assisted installer:

  • On Minikube

    # Step by step
make deploy-olm
make deploy-prometheus
make deploy-grafana

# Or just all-in
make deploy-monitoring

  • On Openshift

    # Step by step
make deploy-prometheus TARGET=oc-ingress APPLY_NAMESPACE=false
make deploy-grafana TARGET=oc-ingress APPLY_NAMESPACE=false

# Or just all-in
make deploy-monitoring TARGET=oc-ingress APPLY_NAMESPACE=false

NOTE: To expose the monitoring UI's on your local environment you could follow these steps

kubectl config set-context $(kubectl config current-context) --namespace assisted-installer

# To expose Prometheus
kubectl port-forward svc/prometheus-k8s 9090:9090

# To expose Grafana
kubectl port-forward svc/grafana 3000:3000

Now you just need to access http://127.0.0.1:3000 to access to your Grafana deployment or http://127.0.0.1:9090 for Prometheus.

Deploy by tag

This feature is for internal usage and not recommended to use by external users. This option will select the required tag that will be used for each dependency. If deploy-all use a new tag the update will be done automatically and there is no need to reboot/rollout any deployment.

Deploy images according to the manifest:

skipper make deploy-all DEPLOY_MANIFEST_PATH=./assisted-installer.yaml

Deploy images according to the manifest in the assisted-installer-deployment repo (require git tag/branch/hash):

skipper make deploy-all DEPLOY_MANIFEST_TAG=master

Deploy all the images with the same tag. The tag is not validated, so you need to make sure it actually exists.

skipper make deploy-all DEPLOY_TAG=<tag>

Default tag is latest
