Unix time format in Azure Resource Manager templates

The Unix time format is represented in seconds elapsed since 01.01.1970 UTC. So, it is different from the standard time format we are used to. Depending on the Azure service some attributes in the Azure API / ARM template require the Unix time format especially Azure Key Vault keys and secrets. Those ones have two attributes the not before (nbf) and expiry (exp) date requiring the Unix time format. -> Read more [...]

Using distroless images in Istio on Azure Kubernetes Service

Looking at Docker Hub Istio provides the option using distroless images since version 1.3.0. As it is always a good idea on a Kubernetes cluster to reduce the attack surface, especially when running a managed Kubernetes cluster like Azure Kubernetes Service, using distroless images is one option of it. Per default Istio does not use the distroless image versions. So, you need to opt in for Read more [...]
