Claudie v0.15

Upgrade to this release from previous v0.14.x version requires manual intervention (due to the MongoDB version upgrade).

Readme Before Deploying

Autoscaler changes

The autoscaler will no longer be deployed by Claudie. From now it becomes an opt-in paid feature.

Make sure no tasks are scheduled

Before deploying this Claudie release, make sure no tasks are actively being worked on. You can verify this via

kubectl get inputmanifests

All of the input manifests should be in state WATCHING_FOR_CHANGES.

You can also scale down the number of replicas for the manager service to 0 to be sure no tasks are scheduled.

kubectl scale deploy/manager -n claudie --replicas=0

MongoDB

This version of Claudie updates MongoDB.

It is required that before deploying this new version that the number of replicas of the current deployment for MongoDB is scaled down to 0.

kubectl scale deploy/mongodb -n claudie --replicas=0

After deploying:

  • Check if the version running in the primary replica is 8.3 via
kubectl exec -it <primary-mongo-pod> -n claudie -- mongosh \
  -u <username> -p <password> --authenticationDatabase admin \
  --eval "db.adminCommand({ buildInfo: 1 }).version"
  • Set the feature set to version 8.3
kubectl exec -it <primary-mongo-pod> -n claudie -- mongosh \
  -u <username> -p <password> --authenticationDatabase admin \
  --eval "db.adminCommand( { setFeatureCompatibilityVersion: '8.3', confirm: true } )"

This command must perform writes to an internal system collection. If for any reason the command does not complete successfully, you can safely retry the command as the operation is idempotent.

  • Verify the command successfully updated the feature set.
kubectl exec -it <primary-mongo-pod> -n claudie -- mongosh \
  -u <username> -p <password> --authenticationDatabase admin \
  --eval "db.adminCommand({ getParameter: 1, featureCompatibilityVersion: 1 })"

Deployment

To deploy Claudie v0.15.x, please:

  1. Download Claudie.yaml from release page

  2. Verify the checksum with sha256 (optional)

We provide checksums in claudie_checksum.txt you can verify the downloaded yaml files against the provided checksums.

  1. Install Claudie using kubectl

We strongly recommend changing the default credentials for MongoDB, MinIO before you deploy it.

kubectl apply -f https://github.com/berops/claudie/releases/latest/download/Claudie.yaml

To further harden Claudie, you may want to deploy our pre-defined network policies: 

# for clusters using cilium as their CNI
kubectl apply -f https://github.com/berops/claudie/releases/latest/download/network-policy-cilium.yaml

# other
kubectl apply -f https://github.com/berops/claudie/releases/latest/download/network-policy.yaml
