Use odo with OpenShift Service Mesh (aka Istio)
[kind/Feature]
Which functionality do you think we should add?
I think it'd be great to have the ability to use odo in conjunction with Istio/OpenShift Service Mesh. Service Mesh requires an annotation on the DeploymentConfigs created for each component. This is in order for the platform to inject a sidecar container with each pod. (spec/template/metadata/annotations of sidecar.istio.io/inject: "true").
See ref docs here: https://docs.openshift.com/container-platform/4.3/service_mesh/service_mesh_day_two/prepare-to-deploy-applications-ossm.html#ossm-automatic-sidecar-injection_deploying-applications-ossm
Additionally, Services that get created should have port names that follow the naming listed here (for full support of routing and metrics): https://istio.io/docs/ops/configuration/traffic-management/protocol-selection/ e.g.
spec:
ports:
- port: 8080
targetPort: 8080
name: http
Why is this needed?
To allow odo to be used in conjunction with OpenShift Service Mesh

Can we keep this open? I think it's still important.
Yes, sorry about not following up on that. This is definitely something that we want to get to. Now we are finishing our transition to using Devfiles as a common format to describe the development environment. We will look into this right after we finish this transition
Being able to use annotations with odo would also be useful for dapr.io which also uses a sidecar.
Devfile API was just updated to allow specifying annotations. (https://github.com/devfile/api/pull/661) Before we can levarege this in odo we still need to wait for github.com/devfile/library to implement it.
