Context

The blue compute shop is run by the rebels on the fourth moon of a planet called Yavin.

It is maintained by our trusted friend, developer Cody.

Up and Running in a Minute

The following animation shows the installation and configuration of the full IBM blue compute shop.

Deploy

a) Deploy the shop using a template.

IBM Lab - Excercise 2

Login to the cluster:

oc login --token=... --server=...

IBM Lab - Excercise 3

Get the repo:

git clone https://github.com/ibm-garage-ref-storefront/storefront-tekton
cd storefront-tekton
cp scripts/config ~/config.bc-full

IBM Lab - Excercise 4

New.

Get the Application Load Balancer address:

APPLB=$(oc describe deploy router-default -n openshift-ingress | grep ROUTER_CANONICAL_HOSTNAME |awk '{print $2}')
echo $APPLB

Example output for the prevail workshop environment:

prevail-wrkshp-new-roks-915b3b336cabec458a7c7ec2aa7c625f-0000.ams03.containers.appdomain.cloud

The customer-ms-spring microservice is deliberately deployed as a root pod for educational purposes. For this we have to grant extra permissions.

oc new-project full-bc
oc adm policy add-scc-to-user anyuid -z customer-ms-spring-sa

Deploy the shop using pre-built images (notes: substitute the value for APPLB and NAMESPACE):

NAMESPACE=$(oc project -q)
oc create -f template/blue-compute-template.yaml 
oc new-app --template blue-compute-shop \
-p APPLB=$APPLB \
-p NAMESPACE=$NAMESPACE

b) Check the Deployment

Inspect the full-bc namespace via the web console and see the shop come alive.

You can find the URL of the OpenShift cluster, via:

oc whoami --show-console

Alternatively, you can either rerun the command oc get pods until all pods are started or you can add the parameter -w or --watch to your command. This parameter will watch for status changes and will display them. So to watch your pods use the command:

oc get po -w

Hint: To stop watch just hit ctrl & c.

It will take about 5 minutes before the pods all get into the running state.

The backing services (e.g. mysql) of them will be in state "Pending" until storage gets assigned. Some of them (e.g. the inventory ms) will flip into the "Error" state because they depend on their backing Deployments to be up and "Running". After 4 or 5 minutes the shop will be in state "Running".

Expected result:

c) Configure the shop

Load the database:

bash scripts/inventory/load-database.sh

Example output:

loading the inventory microservice
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                Dload  Upload   Total   Spent    Left  Speed

found pod: inventorymysql-1-6ls87
database initialized succesfully

Make a user (username and passowrd are set in the config file):

bash scripts/customers/make_user.sh

Example output:

Creating user foo.
send of the request to the the customer.add api
HTTP/1.1 201 
Location: http://customer-ms-spring-full-bc.    sion-cluster-ecf58268eb10995f067698dffc82d2a7-0000.eu-gb.containers.    appdomain.cloud/micro/customer/add/225cdeb923604180954a360a6bf6dc47

Notes:

  • we suggest that you create the default user foo with the password bar because that user is used in the testplan to order a calculator from the shop;
  • it will take a minute or 2 before the inventory database content is reflected in the catalog;
  • creating the user will give some complaints about "Insufficient scope", this can be ignored.

d) Enjoy

Login to the shop via the route on the web deployment with user foo (default password is bar), find the URL via:

oc get routes | grep web

Enjoy:

Enjoy

You can login to the shop and place an order.

Order

Things look good, or do they?

2 Tear Down (optional, once all other excercises have been completed)

oc delete project full-bc

3 Trivia

The template has been developed tested on Redhat CRC.

Example on CRC:

oc new-app --template blue-compute-shop \
-p APPLB=apps-crc.testing \
-p NAMESPACE=full-bc
