Istio and Knative Tutorial Pipelines

The Tekton Pipelines that can be used to deploy:

Pre-req

An OpenShift4 cluster with following components:

Create Tutorial Project in OpenShift

oc new-project tutorial && \
! oc create serviceaccount pipeline && \
oc adm policy add-scc-to-user privileged -z pipeline && \
oc adm policy add-role-to-user edit -z pipeline && \
oc adm policy add-scc-to-user privileged -z default && \
oc adm policy add-scc-to-user anyuid -z default && \
oc create -f https://raw.githubusercontent.com/redhat-developer-demos/tutorials-pipelines/pipelines-common/pipeline-role-sa.yaml
 -n tutorial && \
oc policy add-role-to-user pipeline-roles -z pipeline --role-namespace=tutorial

Deploy Nexus(Optional)

To make maven builds faster, we will deploy Sonatype Nexus

oc new-app sonatype/nexus

Tasks

Create the following Tekton tasks which will be used in the Pipelines

oc create -n tutorial \
  -f https://raw.githubusercontent.com/tektoncd/catalog/master/kn/kn.yaml

oc create -n tutorial \
-f https://raw.githubusercontent.com/tektoncd/catalog/master/openshift-client/openshift-client-task.yaml

oc create -n tutorial \
  -f https://raw.githubusercontent.com/redhat-developer-demos/knative-tutorial/master/06-pipelines/build-app-task.yaml

Check the tasks created

tkn task ls
NAME                AGE
NAME               AGE
build-app          3 seconds ago
kn                 5 seconds ago
openshift-client   4 seconds ago

Application Deployment

Download the sources

git clone https://github.com/redhat-developer-demos/tutorials-pipelines
cd tutorials-pipelines

Common

oc create -f pipelines-common/resources.yaml \
  -f pipelines-common/pipeline-deploy.yaml \ #(1)
  -f pipelines-common/pipeline-kn-deploy.yaml #(2)
  1. Pipeline used for vanilla Kubernetes/OpenShift deployment

  2. Pipeline used for serverless (knative) deployment

Customer

# create customer deployment config
oc create -f customer/app.yaml

# start the customer deploy pipeline
tkn pipeline start rhd-tutorial-deploy \
 --param="applicationSrcDir=customer" \
 --param="deploymentConfig=customer" \
 --param="mavenMirrorUrl=http://nexus:8081/nexus/content/groups/public" \
 --resource="app-git=git-source" \
 --resource="app-image=customer-openshift-image" \
 --serviceaccount='pipeline'

Watch the logs of pipeline run using the command

# get the running pipeline id
tkn pipelinerun ls
# get logs of the pipeline via
tkn pipelinerun logs -a -f <id-from-previous-command>

Preference

# create preference deployment config
oc create -f preference/app.yaml

# start preference deployment pipeline
tkn pipeline start rhd-tutorial-deploy \
 --param="applicationSrcDir=preference" \
 --param="deploymentConfig=preference" \
 --param="mavenMirrorUrl=http://nexus:8081/nexus/content/groups/public" \
 --resource="app-git=git-source" \
 --resource="app-image=preference-openshift-image" \
 --serviceaccount='pipeline'

Watch the logs of pipeline run using the command

# get the running pipeline id
tkn pipelinerun ls
# get logs of the pipeline via
tkn pipelinerun logs -a -f <id-from-previous-command>

Recommendation

Version 1

Vanilla OpenShift/Kubernetes Deployment

oc create -f recommendation/app-v1.yaml

tkn pipeline start rhd-tutorial-deploy \
 --param="applicationSrcDir=recommendation" \
 --param="deploymentConfig=recommendation" \
 --param="mavenMirrorUrl=http://nexus:8081/nexus/content/groups/public" \
 --resource="app-git=git-source" \
 --resource="app-image=recommendation-openshift-image-v1" \
 --serviceaccount='pipeline'

Knative Service Deployment

tkn pipeline start rhd-tutorial-kn-deploy \
 --param="applicationSrcDir=recommendation" \
 --param="mavenMirrorUrl=http://nexus:8081/nexus/content/groups/public" \
 --resource="app-git=git-source" \
 --resource="app-image=recommendation-openshift-image-v1" \
 --serviceaccount='pipeline'

Watch the logs of pipeline run using the command

# get the running pipeline id
tkn pipelinerun ls
# get logs of the pipeline via
tkn pipelinerun logs -a -f <id-from-previous-command>

Version 2

Vanilla OpenShift/Kubernetes Deployment

oc create -f recommendation/app-v2.yaml

tkn pipeline start rhd-tutorial-deploy \
 --param="applicationSrcDir=recommendation" \
 --param="deploymentConfig=recommendation" \
 --param="mavenMirrorUrl=http://nexus:8081/nexus/content/groups/public" \
 --resource="app-git=git-source-v2" \
 --resource="app-image=recommendation-openshift-image-v2" \
 --serviceaccount='pipeline'

Knative Service Deployment

tkn pipeline start rhd-tutorial-kn-deploy \
 --param="applicationSrcDir=recommendation" \
 --param="mavenMirrorUrl=http://nexus.rhd-workshop-infra:8081/nexus/content/groups/public" \
 --resource="app-git=git-source-v2" \
 --resource="app-image=recommendation-openshift-image-v2" \
 --serviceaccount='pipeline'

Watch the logs of pipeline run using the command

# get the running pipeline id
tkn pipelinerun ls
# get logs of the pipeline via
tkn pipelinerun logs -a -f <id-from-previous-command>

Knative

oc create -f greeter/pipeline-deploy.yaml \
  -f greeter/pipeline-run.yaml

Watch the logs of pipeline run using the command

# get the running pipeline id
tkn pipelinerun ls
# get logs of the pipeline via
tkn pipelinerun logs -a -f <id-from-previous-command>

Cleanup

  • Delete all pipeline runs

tkn pipelinerun ls | awk 'NR>1{print $1}' | xargs oc delete pipelinerun
  • Delete all pipelines

oc delete -f pipelines-commons/pipeline-deploy.yaml
  • Delete applications

oc delete -f recommendation/app-v1.yaml \
  -f recommendation/app-v2.yaml \
  -f preference/app.yaml \
  -f customer/app.yaml
