This is one of the many benefits of the “side car injection” approach that istio has embrace , bit intrusive yea , but so far seems to work nicely. Ok so quickly you can deploy jaeger and zipkin by enabling it on the chart:https://brainbit.uk/posts/istio-mixer-adapters/Tue, 24 Jul 2018 12:31:22 +0000https://brainbit.uk/posts/istio-mixer-adapters/Quick article about Mixer and adapters , one of the things i wanted to find out is what’s the involvement of Istio/Mixer when traffic is sent from one pod to another , having that kind of segregation or isolation could be useful , for example let’s imagine a 3 tier app in 3 different pods , you wouldn’t want your view layer speaking directly with the model , for example:https://brainbit.uk/posts/k-istio-little-deep-dive/Sat, 21 Jul 2018 19:51:13 +0000https://brainbit.uk/posts/k-istio-little-deep-dive/I’ve been playing a little bit with Istio mostly egress , but today i wanted to write about ingresses . Basically Istio ingresses are a number of proxies (envoy) that kind of talk to each other to deal with access , throttling and app routing in general. What is really interesting about the istio approach is the sidecar injection, imagine that you’re running a container execs nginx (port80 )S What istio does is “inject” a sidecar container , that runs on the same pod , that means , sharing the kernel network namespace with privileged mode and NET_ADMIN capabilities.
