This is a more general form of . I don't have immediate plans to work on either of them, so you're welcome to take it.
sounds good. Do you want me to close this as a dupe?
I think there's a useful distinction between the two issues. If we support only , that would be enough to but this one tracks the idea of supporting arbitrary field selectors. By the way, if I recall correctly, when I applied the hack mentioned in the other thread to skip the step for CRDs, I think I saw that actually arbitrary field selectors worked too (not just ). That would mean enabling this might be easy on a technical level, although we may need to think through whether this could tie our hands if we ever wanted to add versioning support for CRD in the future. This issue is a better home for that discussion than the other one.
This would help a lot with debugging in prow. Today, the only thing we can do is bubble up information from the spec of a prowjob as labels and use a label selector.
What about just having 's just return the passed in label and value without any "conversion" for now?
I don't think we'd want to do it for all Unstructured, since there's no guarantee all Unstructured objects are CRD objects. However, it should be pretty easy to arrange for ConvertFieldLabel to be a no-op for CRD objects, which makes sense currently because CRD only allows one version for a given resource.

We just need to make sure this will not prevent us from doing more with CRD versioning in the future. My suspicion is that it should be fine, but I haven't investigated properly.
ok, I can put together a PR to make this change. any gut reactions?
PR:
I am sorry to comment on this closed thread. Currently, I am working on a CRD and needs to support arbitrary field selectors. I've tried to do it by learning from what you do for . But it always throws error: . So, I am wondering if I am doing something wrong or it only supports limited field selectors for CRD, which is stated . Here is my code snippet:
CRDs still only support namespace and name for field selectors
Any plan to support arbitrary field selector for CRDs?
Not currently

Follow a TPR an instance a single instance return 400. (watch a collection of TPR works) master and kubectl version: 1.7.1 CRD has the same issue. /assign
There are no sig labels on this issue. Please by: a sig: e.g., to notify the contributor experience sig, OR the label manually: e.g., to apply the label Note: Method 1 will trigger an email to the group. You can find the group list and label list . The in the method 1 has to be replaced with one of these: bugs, feature-requests, pr-reviews, test-failures, proposals
I was able to reproduce this with CRD on master. The problem is that kubectl implements a watch on a single object as a watch on the collection with a field selector that filters by . However, field selectors don't work on CRD objects because they are stored as , which does not support : This method is used to transform the field selector from versioned to internal field names: As a test, I bypassed that check for Unstructured objects, and watches on single CRD objects started working. Given that CRD doesn't support multiple versions anyway, it seems feasible to support this with a properly-targeted override of specific to CRD objects. cc
If we could support name and namespace generally on all objects containing object meta, I think I'm in favor of the concept.
I think it's feasible to fix this for CRD at some point. However, given that TPR is already gone in master, I don't think it's worth fixing for TPR unless it's somehow a regression in 1.7. Do you have any objections to that?
Having CRD support is good enough for me and service catalog. Will you backport the fix for CRD to 1.7?
At this stage I wouldn't expect that since it isn't a regression (I don't think) for either extension mechanism.

I am also getting the same error when i try to watch CRDs and filter on a specific field. Im a currently using the to watch for CRDs. On a related note, i noticed that the takes a . Is there a way to pass a label selector so that i can watch CRDs using labels?
Also is this issue slated for 1.8?

(For CRDs that is)
The general issue of supporting field selectors for CRD is tracked in . I don't think it's slated for 1.8. The methods on should take a , which can contain an optional .
