Use Memorystore
Duration: 10 min | Persona: Apps Operator
In this section, you will update the OnlineBoutique’s cartservice
app in order to point to the Memorystore (Redis) instance previously created.
Initialize variables:
WORK_DIR=~/
source ${WORK_DIR}acm-workshop-variables.sh
Update RepoSync
to deploy the Online Boutique’s Helm chart
Get Memorystore (Redis) connection information:
export REDIS_IP=$(gcloud redis instances describe $REDIS_NAME --region $GKE_LOCATION --project $TENANT_PROJECT_ID --format='get(host)')
export REDIS_PORT=$(gcloud redis instances describe $REDIS_NAME --region $GKE_LOCATION --project $TENANT_PROJECT_ID --format='get(port)')
Define the RepoSync
to deploy the Online Boutique’s Helm chart with the cartservice
pointing to the Memorystore (Redis) database:
cat <<EOF > ${WORK_DIR}$GKE_CONFIGS_DIR_NAME/repo-syncs/$ONLINEBOUTIQUE_NAMESPACE/repo-sync.yaml
apiVersion: configsync.gke.io/v1beta1
kind: RepoSync

This will change the REDIS_ADDR
environment variable of the cartservice
to point to the Memorystore (Redis) database as well as removing the Deployment
and the Service
of the default in-cluster redis
database.
Deploy Kubernetes manifests
cd ${WORK_DIR}$GKE_CONFIGS_DIR_NAME/
git add . && git commit -m "Use Memorystore (Redis)" && git push origin main
Check deployments
List the Kubernetes resources managed by Config Sync in GKE cluster for the Online Boutique apps repository:
Run this command and click on this link:
echo -e "https://console.cloud.google.com/kubernetes/config_management/packages?project=${TENANT_PROJECT_ID}"
Wait until you see the Sync status
column as Synced
and the Reconcile status
column as Current
.
Run this command:
gcloud alpha anthos config sync repo describe \
--project $TENANT_PROJECT_ID \
--managed-resources all \
--sync-name repo-sync \
--sync-namespace $ONLINEBOUTIQUE_NAMESPACE
Wait and re-run this command above until you see "status": "SYNCED"
.
List the GitHub runs for the GKE cluster configs repository:
cd ${WORK_DIR}$GKE_CONFIGS_DIR_NAME && gh run list
Check the Online Boutique website
Navigate to the Online Boutique website, click on the link displayed by the command below:
echo -e "https://${ONLINE_BOUTIQUE_INGRESS_GATEWAY_HOST_NAME}"
You should still have the Online Boutique website working successfully, but now linked to an external Memorystore (Redis) database. Congrats!
