Run example

Universal workflow to run any example:

Setup testing cluster

# argo-cd, cert-manager, dapr, dex, external-dns, external-secrets,
# ingress-nginx, istio, kube-prometheus-stack, kubecost, kyverno,
# msr, netapp, nvidia, open-webui, opencost, prometheus, pure, velero
export APP="dapr"
export TEST_MODE="adopted" # Supported values: aws, azure, adopted

# Add adopted cluster to k0rdent
./scripts/deploy_cld.sh

Deploy application

Create a testing application release, verify it's installed and it exposess frontend if needed. Then uninstall it and verify it was really removed. You can use this section over and over for a different applications.

# Install k0rdent service template
./scripts/install_servicetemplates.sh

# Deploy service using multiclusterservice
# Note: there is complete configurable values list in $APP/values-orig.yaml folder.
./scripts/deploy_mcs.sh

# Test webpage if exposed
./scripts/test_webpage.sh

Test application uninstallation:

# Cleaning section
# Remove multiclusterservice
./scripts/remove_mcs.sh

Delete testing cluster:

# Be careful, you can use existing cluster for other examples!!!
./scripts/remove_cld.sh
