[PodPreset] Enabling PodPreset support injecting init-containers and side-car containers

[Guang Ya Liu]

Hi,

I found that now the PodPreset only support injecting Env, EnvFrom, and VolumeMounts to a PodSpec, sometimes, many PodSpec may share same init-container and side-car container, such as istio, so any plan to support injecting init-container and side-car containers via PodPreset?

Thanks,

Guangya

Hi Guang,

Use case for injecting containers using PodPreset has been discussed and is on the roadmap, but has not been prioritized for Beta yet. If you are blocked on it, you should explore using "Initializers" which is introduced in 1.7 release. Here is the link --> https://kubernetes.io/docs/admin/extensible-admission-controllers/

Thanks Sunil, this can help me, but I may need to develop a webhook for this. 

I still think using PodPreset is the direction for this problem, can you please share me the roadmap of PodPreset and what is the priority of this?

Thanks,

Guangya
