There are three ways to achieve docker in docker Note that deleting the operator before the IstioOperator CR and corresponding Istio revision are fully removed may result in leftover Istio resources. If you omit the revision flag, then all revisions of Istio operator will be removed. Then you can remove the Istio operator for the old revision by running the following command: $ istioctl operator remove -revision Wait until Istio is uninstalled - this may take some time.
#DOCKER RUN IMAGE AT REVISION UPGRADE#
If you used the operator to perform a canary upgrade of the control plane, you can uninstall the old control plane and keep the new one by deleting the old in-cluster IstioOperator CR, which will uninstall the old revision of Istio: $ kubectl delete -n istio-system example-istiocontrolplane To complete the upgrade, label the workload namespaces with istio.io/rev=1-8-1 and restart the workloads, asĮxplained in the Data plane upgrade documentation. $ kubectl get services -n istio-system -l app=istiod
After that, you will have two control plane deployments and services running side-by-side: $ kubectl get pod -n istio-system -l app=istiod Your updated IstioOperator CR should look something like this: $ cat example-istiocontrolplane-1-8-1.yamlĪpply the updated IstioOperator CR to the cluster. Make a copy of the example-istiocontrolplane CR and save it in a file named example-istiocontrolplane-1-8-1.yaml.Ĭhange the name to example-istiocontrolplane-1-8-1 and add revision: 1-8-1 to the CR.

Note that you need to download the Istio release

You can alternatively use Helm to deploy another operator with a different revision setting: $ helm install istio-operator manifests/charts/istio-operator \ IstioOperator CR (here, we assume the target revision is 1.8.1): $ istio-1.8.1/bin/istioctl operator init -revision 1-8-1 Then, run the following command to install the new target revision of the Istio control plane based on the in-cluster Istio-system example-istiocontrolplane HEALTHY 11mĭownload and extract the istioctl corresponding to the version of Istio you wish to upgrade to. The process for canary upgrade is similar to the canary upgrade with istioctl.įor example, to upgrade the revision of Istio installed in the previous section, first verify that the IstioOperator CR named example-istiocontrolplane exists in your cluster: $ kubectl get iop -all-namespaces You should see that the istio-operator pod has restarted and its version has changed to the target version: $ kubectl get pods -namespace istio-operator \ Profile with the following command: $ kubectl apply -f - /bin/istioctl operator init The controller will detect the change and respond by updatingįor example, you can switch the installation to the default Now, with the controller running, you can change the Istio configuration by editing or replacing Istio-ingressgateway-86cb4b6795-9jlrk 1/1 Running 0 68s Istio-egressgateway-696cccb5-m8ndk 1/1 Running 0 68s NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE You can confirm the Istio control plane services have been deployed with the following commands: $ kubectl get services -n istio-system The Istio installation completes within 120 The creation of the IstioOperator resource.
The Istio operator controller begins the process of installing Istio within 90 seconds of See the istioctl operator init command reference for details.
For example, you can pass one or more namespaces to watch using the -watchedNamespaces flag: $ istioctl operator init -watchedNamespaces=istio-namespace1,istio-namespace2 You can configure which namespace the operator controller is installed in, the namespace(s) the operator watches, the installed Istio image sources and versions, and more. The operator custom resource definition.This command runs the operator by creating the following resources in the istio-operator namespace: The istioctl command can be used to automatically deploy the Istio operator: $ istioctl operator init Perform any necessary platform-specific setup.Ĭheck the Requirements for Pods and Services. To avoid a vulnerability, ensure that the operator deployment is sufficiently secured. Whereas with an operator, an in-cluster pod will run the operation in its security context. With the istioctl install command, the operation will run in the admin user’s security context, Using an operator does have a security implication.
