Optimize T4K Backups with StormForge
This article helps users to install and configure StormForge. It can be used find the optimized resource configuration of T4K to run the backup
Today many enterprises running Kubernetes applications are not aware of a way to monitor and optimize the resources used by those applications.
StormForge is a platform that helps users to automate resource tuning and deliver the best Kubernetes application performance at the lowest possible cost. StormForge allows users to run an experiment with a user specified number of trials. The trial runs on an application to find the optimized resource configuration required to perform certain operations. It uses machine learning algorithms to pick the combination of CPU, RAM and other resources to run a trial.
Follow below instructions to install and configure the StormForge with Trilio for Kubernetes and run the experiment to find the optimized resource configuration of T4K
- 1.Download and install redskyctl CLI
curl -L https://app.stormforge.io/downloads/redskyctl-linux-amd64.tar.gz | tar x
sudo mv redskyctl /usr/local/bin/
2. Authorize the linux server from where redskyctl will be evoked to run the experiment
redskyctl login --force
Enter the URL generated by above command into the browser to authorize the Linux server
https://auth.carbonrelay.io/authorize?audience=https%3A%2F%2Fapi.carbonrelay.io%2Fv1%2F&client_id=pE3kMKdrMTdW4DOxQHesyAuFGNOWaEke&code_challenge=nUaqSbjv0grweFAMrv_Zk9KBg_8o-4AQAnwxpijJlGk&code_challenge_method=S256&redirect_uri=http%3A%2F%2F127.0.0.1%3A8085%2F&response_type=code&scope=register%3Aclients+offline_access&state=nHGW89zTYO39loEALGTsig
3. Verify if you are connected to the server where you want to run the experiment
kubectl get nodes

ip-mytesthost-m3.us-east-2.compute.internal Ready controlplane,etcd 4d5h v1.19.9
4. Initiate the redsky controller manager pod on the kubernetes cluster
redskyctl init

5. Verify if the redsky-controller-manager is running on k8s cluster
kubectl get pod -n redsky-system
NAME READY STATUS RESTARTS AGE
redsky-controller-manager-6cbb796b79-5wnz8 1/1 Running 1 4d4h
6. Authorize the kubernetes cluster, where user want to run the experiment and application is present
redskyctl authorize-cluster
secret/redsky-manager configured
deployment.apps/redsky-controller-manager patched
1. There must be an application running in the namespace which will be used to perform the backup by StormForge experiment
kubectl get pods | grep k8s-demo-app
k8s-demo-app-frontend-7c4bdbf9b-bbz2z 1/1 Running 1 4d4h
k8s-demo-app-frontend-7c4bdbf9b-c84m7 1/1 Running 1 4d4h

k8s-demo-app-mysql-754f46dbd7-v85mh 1/1 Running 2 4d4h
2. It is expected that Trilio for Kubernetes product is installed on the K8s cluster
kubectl get pods | grep k8s-triliovault
k8s-triliovault-admission-webhook-7c5b454ff4-85t92 1/1 Running 1 4d3h
k8s-triliovault-control-plane-54594f5796-vpz4r 2/2 Running 2 4d3h

triliovault-operator-k8s-triliovault-operator-66b6d9d96f-k8fjs 1/1 Running 1 4d4h
3. Verify that T4K
License is applied to initiate the backupkubectl get license
NAME STATUS MESSAGE CURRENT NODE COUNT GRACE PERIOD END TIME EDITION CAPACITY EXPIRATION TIME
test-license-1 Active Cluster License Activated successfully. 9 Basic 10 2022-04-30T00:0
4. Make sure that the
Target to store the backup is configured and is in Available statekubectl get target
NAME TYPE THRESHOLD CAPACITY VENDOR STATUS BROWSING ENABLED
demo-s3-target ObjectStore 100Gi AWS Available
5. Create a
Backup plan for the application or namespacekubectl apply -f app/mysql-sample-backupplan.yaml
kubectl apply -f app/mysql-sample-backupplan-1.yaml
6. Verify the backup plan is created correctly
kubectl get backupplan
NAME TARGET RETENTION POLICY INCREMENTAL SCHEDULE FULL BACKUP SCHEDULE STATUS
mysql-label-backupplan demo-s3-target Available
mysql-label-backupplan-1 demo-s3-target Available
- 1.Users need to create a backup, bash script to monitor the backup and tvk-manager configmap.
kubectl create configmap bashscript --from-file=configmaps/bash-script.sh
kubectl create configmap bashscript1 --from-file=configmaps/bash-script-1.sh
kubectl create configmap backup --from-file=configmaps/mysql-sample-backup.yaml
kubectl create configmap backup1 --from-file=configmaps/mysql-sample-backup-1.yaml
kubectl create configmap tvkmanager --from-file=configmaps/tvk-manager.yaml
2. User has all required entities in place to start the experiment
kubectl apply -f experiment/tvk-scale-2-backup-delete-parallel-prod.yaml
3. User can monitor the running experiment being performed for each backup.
kubectl get experiment
NAME STATUS
tvk-scale-400-backup-delete-parallel-prod Running
4. Check the new
Trial running by the experimentkubectl get trial
NAME STATUS ASSIGNMENTS VALUES
tvk-scale-400-backup-delete-parallel-prod-000 Setting up deploymentMemory=512, deploymentCpu=250, metaCpu=500, metaMemory=512, dataMemory=1536, dataCpu=1200
5. Verify the jobs
kubectl get jobs
NAME COMPLETIONS DURATION AGE
tvk-scale-2-backup-delete-parallel-prod-001 0/1 4d3h 4d3h
tvk-scale-2-backup-delete-parallel-prod-001-create 1/1 51s 4d3h
tvk-scale-2-backup-delete-parallel-prod-001-delete 1/1 6s 4d3h
- 1.After the experiment is in
runningstate, user can view the progress at the StormForge UI using the login they have configured.
StormForge Experiment Trial Run Graph
2. Once the experiment run is complete, StormForge experiment will show the recommended configuration with resource details.
StormForge Recommended Resource Configuration
- 1.After the experiment run is complete, user can remove the StormForge redsky-controller-manager with simple commands
- Delete the experiment from kubernetes cluster along with all other resources
kubectl apply -f experiment/tvk-scale-2-backup-delete-parallel-prod.yaml
- Delete the experiment from redsky tenant
redskyctl delete exp tvk-scale-2-backup-delete-parallel-prod
Note: If you delete the experiment from redsky tenant, it will get deleted from the StormForge UI as well.
2. If user is facing any issues while running the experiment, they can check logs of redsky-controller-manager
kubectl logs redsky-controller-manager-6cbb796b79-5wnz8 -n redsky-system
Using StormForge, users can create desired experiments. Users run those experiments on Kubernetes cluster with applications running and perform operations like Backup/Restore. StormForge UI will provide the analysis through a well curated graph. It will show the best to worst combination of resources used to perform the operation in a particular trial. These optimized resource combinations can be applied in the production clusters to achieve the desired RPO/RTO.
