Create services before other objects, or at least before objects that depend upon them. Namespace-relative DNS mitigates this some, but most users are still using service environment variables. [#1768](https://github.com/GoogleCloudPlatform/kubernetes/issues/1768) +1. Finish rolling update [#1353](https://github.com/GoogleCloudPlatform/kubernetes/issues/1353) + 1. Friendly to auto-scaling [#2863](https://github.com/GoogleCloudPlatform/kubernetes/pull/2863#issuecomment-69701562) + 1. Rollback (make rolling-update reversible, and complete an in-progress rolling update by taking 2 replication controller names rather than always taking a file) + 1. Rollover (replace multiple replication controllers with one, such as to clean up an aborted partial rollout) + 1. Write a ReplicationController generator to derive the new ReplicationController from an old one (e.g., `--image-version=newversion`, which would apply a name suffix, update a label value, and apply an image tag) + 1. Use readiness [#620](https://github.com/GoogleCloudPlatform/kubernetes/issues/620) + 1. Perhaps factor this in a way that it can be shared with [Openshift’s deployment controller](https://github.com/GoogleCloudPlatform/kubernetes/issues/1743) + 1. Rolling update service as a plugin +1. Kind-based filtering on object streams -- only operate on the kinds of objects specified. This would make directory-based kubectl operations much more useful. Users should be able to instantiate the example applications using `kubectl create -f <example-dir> ...` +1. Improved pretty printing of endpoints, such as in the case that there are more than a few endpoints +1. Service address/port lookup command(s) +1. List supported resources +1. Swagger lookups [#3060](https://github.com/GoogleCloudPlatform/kubernetes/issues/3060) +1. --name, --name-suffix applied during creation and updates +1. --labels and opinionated label injection: --app=foo, --tier={fe,cache,be,db}, --uservice=redis, --env={dev,test,prod}, --stage={canary,final}, --track={hourly,daily,weekly}, --release=0.4.3c2. Exact ones TBD. We could allow arbitrary values -- the keys are important. The actual label keys would be (optionally?) namespaced with kubectl.kubernetes.io/, or perhaps the user’s namespace. +1. --annotations and opinionated annotation injection: --description, --revision +1. Imperative updates. We'll want to optionally make these safe(r) by supporting preconditions based on the current value and resourceVersion. + 1. annotation updates similar to label updates + 1. other custom commands for common imperative updates + 1. more user-friendly (but still generic) on-command-line json for patch +1. We also want to support the following flavors of more general updates: + 1. whichever we don’t support: + 1. safe update: update the full resource, guarded by resourceVersion precondition (and perhaps selected value-based preconditions) + 1. forced update: update the full resource, blowing away the previous Spec without preconditions; delete and re-create if necessary + 1. diff/dryrun: Compare new config with current Spec [#6284](https://github.com/GoogleCloudPlatform/kubernetes/issues/6284) + 1. submit/apply/reconcile/ensure/merge: Merge user-provided fields with current Spec. Keep track of user-provided fields using an annotation -- see [#1702](https://github.com/GoogleCloudPlatform/kubernetes/issues/1702). Delete all objects with deployment-specific labels. +1. --dry-run for all commands +1. Support full label selection syntax, including support for namespaces. +1. Wait on conditions [#1899](https://github.com/GoogleCloudPlatform/kubernetes/issues/1899) +1. Make kubectl scriptable: make output and exit code behavior consistent and useful for wrapping in workflows and piping back into kubectl and/or xargs (e.g., dump full URLs?, distinguish permanent and retry-able failure, identify objects that should be retried) + 1. Here's [an example](http://techoverflow.net/blog/2013/10/22/docker-remove-all-images-and-containers/) where multiple objects on the command line and an option to dump object names only (`-q`) would be useful in combination. [#5906](https://github.com/GoogleCloudPlatform/kubernetes/issues/5906) +1. Easy generation of clean configuration files from existing objects (including containers -- podex) -- remove readonly fields, status + 1. Export from one namespace, import into another is an important use case +1. Derive objects from other objects + 1. pod clone + 1. rc from pod + 1. --labels-from (services from pods or rcs) +1. Kind discovery (i.e., operate on objects of all kinds) [#5278](https://github.com/GoogleCloudPlatform/kubernetes/issues/5278) +1. A fairly general-purpose way to specify fields on the command line during creation and update, not just from a config file +1. Extensible API-based generator framework (i.e. invoke generators via an API/URL rather than building them into kubectl), so that complex client libraries don’t need to be rewritten in multiple languages, and so that the abstractions are available through all interfaces: API, CLI, UI, logs, ... [#5280](https://github.com/GoogleCloudPlatform/kubernetes/issues/5280) + 1. Need schema registry, and some way to invoke generator (e.g., using a container) + 1. Convert run command to API-based generator +1. Transformation framework + 1. More intelligent defaulting of fields (e.g., [#2643](https://github.com/GoogleCloudPlatform/kubernetes/issues/2643)) +1. Update preconditions based on the values of arbitrary object fields. +1. Deployment manager compatibility on GCP: [#3685](https://github.com/GoogleCloudPlatform/kubernetes/issues/3685) +1. Describe multiple objects, multiple kinds of objects [#5905](https://github.com/GoogleCloudPlatform/kubernetes/issues/5905) +1.
