# Upgrade AKO from OperatorHub.io This is the procedure to upgrade AKO, [installed from OperatorHub.io](https://aerospike.com/docs/kubernetes/4.1.x/install/olm), to version 4.1.2. ::: note If you are running an AKO version older than 4.0.2, you must first upgrade to 4.0.2 before upgrading to 4.1.2: - [Upgrade to 4.0.2](https://aerospike.com/docs/kubernetes/4.0.x/manage/upgrade/upgrading-operator) ::: ## Verify that AKO 4.1.2 is available Use the following command to verify 4.1.2 as the current CSV version: ```plaintext kubectl get packagemanifests -l catalog=operatorhubio-catalog,provider=Aerospike -o yaml | grep currentCSV: ``` The following should appear: Terminal window ```bash - currentCSV: aerospike-kubernetes-operator.v2.5.0 - currentCSV: aerospike-kubernetes-operator.v4.1.2 ``` ## Upgrade AKO Based on the [installPlanApproval](https://olm.operatorframework.io/docs/concepts/crds/subscription/#manually-approving-upgrades-via-subscriptions) mode, the upgrade of AKO can be one of - [Automatic](#automatic) - the default when installing AKO from OperatorHub.io. - [Manual](#manual) - if the OperatorHub.io subscription has been edited to use manual approval. ### Automatic The standard install procedure sets up automatic upgrade approval for AKO. In this case OLM automatically installs AKO version 4.1.2. No manual steps are necessary. You can skip ahead to [verification](#verify-that-the-operator-is-upgraded). ### Manual If the OperatorHub.io subscription has been edited to use manual approval, you need to approve the upgrade as follows: Verify that the InstallPlan for version 4.1.2 has been created. ```plaintext kubectl get installplan -n operators | grep aerospike ``` Sample output with an InstallPlan for version 4.1.2. Terminal window ```bash NAME CSV APPROVAL APPROVED install-2tg7p aerospike-kubernetes-operator.v4.1.2 Manual false ``` In this example, the upgrade is not applied since the `APPROVED` status is `false`. To approve the upgrade, set the `approved` field in the InstallPlan to `true`: Terminal window ```bash kubectl patch installplan -n operators --type merge --patch '{'{'}"spec":{'{'}"approved":true{'}'}{'}'}' $(kubectl get installplan -n operators | grep "aerospike-kubernetes-operator.v4.1.2" | cut -f 1 -d " ") ``` ## Verify that the Operator is upgraded Run the following command: ```plaintext kubectl get csv -n operators | grep aerospike ``` The upgrade can take some time. The CSV for version 4.1.2 goes through the phases `Pending`, `Installing`, `InstallReady` and finally `Succeeded`. The sample output below illustrates a successful upgrade: Terminal window ```bash NAME DISPLAY VERSION REPLACES PHASE aerospike-kubernetes-operator.v4.1.2 Aerospike Kubernetes Operator 4.1.2 aerospike-kubernetes-operator.v4.0.2 Succeeded ``` ## Check operator logs AKO runs as two replicas by default for higher availability. Run the following command to follow the logs for the AKO pods. ```plaintext kubectl -n operators logs -f deployments/aerospike-operator-controller-manager manager ``` Sample output: Terminal window ```shell 2025-08-06T08:42:37Z INFO setup Initializing webhook certificate watcher using provided certificates {"webhook-cert-path": "/tmp/k8s-webhook-server/serving-certs", "webhook-cert-name": "tls.crt", "webhook-cert-key": "tls.key"} 2025-08-06T08:42:37Z INFO controller-runtime.certwatcher Updated current TLS certificate 2025-08-06T08:42:37Z INFO setup Init aerospike-server config schemas 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "6.0.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "6.3.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "7.1.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "8.0.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "8.1.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "6.1.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "6.2.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "6.4.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "7.0.0"} 2025-08-06T08:42:37Z DEBUG setup Config schema added {"version": "7.2.0"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a mutating webhook {"GVK": "asdb.aerospike.com/v1, Kind=AerospikeCluster", "path": "/mutate-asdb-aerospike-com-v1-aerospikecluster"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/mutate-asdb-aerospike-com-v1-aerospikecluster"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a validating webhook {"GVK": "asdb.aerospike.com/v1, Kind=AerospikeCluster", "path": "/validate-asdb-aerospike-com-v1-aerospikecluster"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/validate-asdb-aerospike-com-v1-aerospikecluster"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a mutating webhook {"GVK": "asdb.aerospike.com/v1beta1, Kind=AerospikeBackupService", "path": "/mutate-asdb-aerospike-com-v1beta1-aerospikebackupservice"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/mutate-asdb-aerospike-com-v1beta1-aerospikebackupservice"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a validating webhook {"GVK": "asdb.aerospike.com/v1beta1, Kind=AerospikeBackupService", "path": "/validate-asdb-aerospike-com-v1beta1-aerospikebackupservice"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/validate-asdb-aerospike-com-v1beta1-aerospikebackupservice"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a mutating webhook {"GVK": "asdb.aerospike.com/v1beta1, Kind=AerospikeBackup", "path": "/mutate-asdb-aerospike-com-v1beta1-aerospikebackup"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/mutate-asdb-aerospike-com-v1beta1-aerospikebackup"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a validating webhook {"GVK": "asdb.aerospike.com/v1beta1, Kind=AerospikeBackup", "path": "/validate-asdb-aerospike-com-v1beta1-aerospikebackup"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/validate-asdb-aerospike-com-v1beta1-aerospikebackup"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a mutating webhook {"GVK": "asdb.aerospike.com/v1beta1, Kind=AerospikeRestore", "path": "/mutate-asdb-aerospike-com-v1beta1-aerospikerestore"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/mutate-asdb-aerospike-com-v1beta1-aerospikerestore"} 2025-08-06T08:42:37Z INFO controller-runtime.builder Registering a validating webhook {"GVK": "asdb.aerospike.com/v1beta1, Kind=AerospikeRestore", "path": "/validate-asdb-aerospike-com-v1beta1-aerospikerestore"} 2025-08-06T08:42:37Z INFO controller-runtime.webhook Registering webhook {"path": "/validate-asdb-aerospike-com-v1beta1-aerospikerestore"} 2025-08-06T08:42:37Z INFO setup Adding webhook certificate watcher to manager 2025-08-06T08:42:37Z INFO setup Starting manager 2025-08-06T08:42:37Z INFO controller-runtime.metrics Starting metrics server 2025-08-06T08:42:37Z INFO starting server {"name": "health probe", "addr": "[::]:8081"} 2025-08-06T08:42:37Z INFO setup disabling http/2 2025-08-06T08:42:37Z INFO controller-runtime.webhook Starting webhook server 2025-08-06T08:42:37Z INFO setup disabling http/2 2025-08-06T08:42:37Z INFO controller-runtime.webhook Serving webhook server {"host": "", "port": 9443} ```
