A type of flag autoGenerateCert has been changed, now it is an object with two attributes enabled and recreate.
If you previously set autoGenerateCert to true or false you have to set autoGenerateCert.enabled accordingly.
OpenTelemetry Operator 0.82.0 includes a change that allows setting the management state of custom resources PR 1888. Since helm doesn't upgrade CRDs (documented) it is critical to manually update CRDs from chart 0.35.0 or above, possibly using this procedure. If this step isn't taken existing otelcol CRs won't be reconciled by the operator.
Allow using own self-signed certificate
A new flag admissionWebhooks.autoGenerateCert has been added. If you want to keep benefiting from the helm generated certificate as in previous versions, you must set admissionWebhooks.certManager.enabled to false and admissionWebhooks.autoGenerateCert to true.
Kubernetes resource names will now use {{opentelemetry-operator.fullname}} as the default value which will change the name of many resources.
Some CI/CD tools might create duplicate resources when upgrading from an older version because of this change.
fullnameOverride can be used to keep deployment resource consistent with the same name during an upgrade.
The v0.17.0 helm chart version changes OpenTelemetry Collector image to the contrib version. If you want to use the core version, set manager.collectorImage.repository to otel/opentelemetry-collector.
Jaeger receiver no longer supports remote sampling. To be able to perform an update, it must be deactivated or replaced by a configuration of the jaegerremotesampling extension.
It is important that the jaegerremotesampling extension and the jaegerreceiver do not use the same port.
To increase the collector version afterwards, the update must be triggered again by restarting the operator. Alternatively, the OpenTelemetryCollector CRD can be re-created. otel-contrib#14707
The ability to use admission webhooks has been moved from admissionWebhooks.enabled to admissionWebhooks.create as it now supports more use cases.
In order to completely disable admission webhooks you need to explicitly set the environment variable ENABLE_WEBHOOKS: "false" in .Values.manager.env .
