`kubectl run --generator` except for `run-pod/v1` is deprecated in v1.12.

{{< /note >}}
|
||||
|
||||
If you explicitly set `--generator`, kubectl uses the generator you specified. If you invoke `kubectl run` and don't specify a generator, kubectl automatically selects which generator to use based on the other flags you set. The following table lists flags and the generators that are activated if you didn't specify one yourself:
|
||||
If you do not specify a generator flag, other flags prompt you to use a specific generator. The following table lists the flags that force you to use specific generators, depending on the version of the cluster:
|
||||
|
||||
{{< table caption="kubectl run flags and the resource they imply" >}}
|
||||
| Flag | Generated Resource |
|
||||
|-------------------------|-----------------------|
|
||||
| `--schedule=<schedule>` | CronJob |
|
||||

|
||||

||||

|
||||

|
||||
| Generated Resource | Cluster v1.4 and later | Cluster v1.3 | Cluster v1.2 | Cluster v1.1 and earlier |

|
||||
| Pod | `--restart=Never` | `--restart=Never` | `--generator=run-pod/v1` | `--restart=OnFailure` OR `--restart=Never` |
|

|
||||
| Deployment | `--restart=Always` | `--restart=Always` | `--restart=Always` | N/A |

|
||||
|
||||
If you don't specify a generator, kubectl pays attention to other flags in the following order:
|
||||
{{< note >}}
|
||||
These flags use a default generator only when you have not specified any flag.
|
||||
This means that when you combine `--generator` with other flags the generator that you specified later does not change. For example, in a cluster v1.4, if you initially specify
|
||||
`--restart=Always`, a Deployment is created; if you later specify `--restart=Always`
|
||||
and `--generator=run/v1`, a Replication Controller is created.
|
||||
This enables you to pin to a specific behavior with the generator,
|
||||
even when the default generator is changed later.
|
||||
{{< /note >}}
|
||||
|
||||
1. `--schedule`
|
||||
1. `--restart`
|
||||
The flags set the generator in the following order: first the `--schedule` flag, then the `--restart` policy flag, and finally the `--generator` flag.
|
||||
|
||||
You can use the `--dry-run` flag to preview the object that would be sent to your cluster, without really submitting it.
|
||||
To check the final resource that was created, use the `--dry-run`
|
||||
flag, which only prints the object that would be sent to the cluster without really sending it.

On the Node: The `kubelet` populates this with the zone information as defined by the `cloudprovider`.
|
||||
This will be set only if you are using a `cloudprovider`. However, you should consider setting this
|
||||
on the nodes if it makes sense in your topology.
|
||||
|
||||
On the PersistentVolume: The `PersistentVolumeLabel` admission controller will automatically add zone labels to PersistentVolumes, on GCE and AWS.
|
||||
|
||||
Kubernetes will automatically spread the Pods in a replication controller or service across nodes in a single-zone cluster (to reduce the impact of failures). With multiple-zone clusters, this spreading behaviour is extended across zones (to reduce the impact of zone failures). This is achieved via _SelectorSpreadPriority_.
|
||||
|
||||
_SelectorSpreadPriority_ is a best effort placement. If the zones in your cluster are heterogeneous (for example: different numbers of nodes, different types of nodes, or different pod resource requirements), this placement might prevent equal spreading of your Pods across zones. If desired, you can use homogenous zones (same number and types of nodes) to reduce the probability of unequal spreading.
|
||||
|
||||
The scheduler (through the _VolumeZonePredicate_ predicate) also will ensure that Pods, that claim a given volume, are only placed into the same zone as that volume. Volumes cannot be attached across zones.
|
||||
|
||||
The actual values of zone and region don't matter. Nor is the node hierarchy rigidly defined.
|
||||
The expectation is that failures of nodes in different zones should be uncorrelated unless the entire region has failed. For example, zones should typically avoid sharing a single network switch. The exact mapping depends on your particular infrastructure - a three rack installation will choose a very different setup to a multi-datacenter configuration.
|
||||
|
||||
If `PersistentVolumeLabel` does not support automatic labeling of your PersistentVolumes, you should consider
|
||||
adding the labels manually (or adding support for `PersistentVolumeLabel`). With `PersistentVolumeLabel`, the scheduler prevents Pods from mounting volumes in a different zone. If your infrastructure doesn't have this constraint, you don't need to add the zone labels to the volumes at all.

## Efficient detection of changes
|
||||
|
||||
To enable clients to build a model of the current state of a cluster, all Kubernetes object resource types are required to support consistent lists and an incremental change notification feed called a **watch**. Every Kubernetes object has a `resourceVersion` field representing the version of that resource as stored in the underlying database. When retrieving a collection of resources (either namespace or cluster scoped), the response from the server will contain a `resourceVersion` value that can be used to initiate a watch against the server. The server will return all changes (creates, deletes, and updates) that occur after the supplied `resourceVersion`. This allows a client to fetch the current state and then watch for changes without missing any updates. If the client watch is disconnected they can restart a new watch from the last returned `resourceVersion`, or perform a new collection request and begin again. See [Resource Version Semantics](#resource-versions) for more detail.

## Resource Versions
|
||||
|
||||
Resource versions are strings that identify the server's internal version of an object. Resource versions can be used by clients to determine when objects have changed, or to express data consistency requirements when getting, listing and watching resources. Resource versions must be treated as opaque by clients and passed unmodified back to the server. For example, clients must not assume resource versions are numeric, and may only compare two resource version for equality (i.e. must not compare resource versions for greater-than or less-than relationships).
|
||||
|
||||
### ResourceVersion in metadata
|
||||
|
||||
Clients find resource versions in resources, including the resources in watch events, and list responses returned from the server:
|
||||
|
||||
[v1.meta/ObjectMeta](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.16/#objectmeta-v1-meta) - The `metadata.resourceVersion` of a resource instance identifies the resource version the instance was last modified at.
|
||||
|
||||
[v1.meta/ListMeta](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.16/#listmeta-v1-meta) - The `metadata.resourceVersion` of a resource collection (i.e. a list response) identifies the resource version at which the list response was constructed.
|
||||
|
||||
### The ResourceVersion Parameter
|
||||
|

The get, list and watch operations support the `resourceVersion` parameter.
|
||||
|
||||
The exact meaning of this parameter differs depending on the operation and the value of the resource version.
|
||||
|
||||
For get and list, the semantics of resource version are:
|
||||
|
||||
**Get:**
|
||||
|
||||
| resourceVersion unset | resourceVersion="0" | resourceVersion="{non-zero version}" |
|
||||
|-----------------------|---------------------|--------------------------------------|
|
||||
| Most Recent | Any | Not older than |
|
||||
|
||||
**List:**
|
||||
|
||||
| paging | resourceVersion unset | resourceVersion="0" | resourceVersion="{non-zero version}" |
|
||||
|-----------|-----------------------|---------------------|--------------------------------------|
|
||||
| no limit | Most Recent | Any | Not older than |
|
||||
| limit="n" | Most Recent | Any | Exact |
|
||||
|
||||
|
||||
The meaning of the get and list semantics are:
|
||||
|
||||
- **Most Recent:** Return data at the most recent resource version. The returned data must be consistent (i.e. served from etcd via a quorum read).
|
||||
- **Any:** Return data at any resource version. The newest available resource version is preferred, but strong consistency is not required; data at any resource version may be served. It is possible for the request to return data at a much older resource version that the client has previously observed, particularly in high availabiliy configurations, due to partitions or stale caches. Clients that cannot tolerate this should not use this semantic.
|
||||
- **Not older than:** Return data at least as new as the provided resource version. The newest available resource version is preferred, but any data not older than this resource version may be served.
|
||||
- **Exact:** Return data at the exact resource version provided.
|
||||
|
||||
For watch, the semantics of resource version are:
|
||||
|
||||
**Watch:**
|
||||
|
||||
| resourceVersion unset | resourceVersion="0" | resourceVersion="{non-zero version}" |
|
||||
|-------------------------------------|----------------------------|--------------------------------------|
|
||||
| Get State and Start at Most Recent | Get State and Start at Any | Start at Exact |
|
||||
|
||||
The meaning of the watch semantics are:
|
||||
|
||||
- **Get State and Start at Most Recent:** Start a watch at the most recent resource version, which must be consistent (i.e. served from etcd via a quorum read). To establish initial state, the watch begins with synthetic “Added” events of all resources instances that exist at the starting resource version. All following watch events are for all changes that occured after the resource version the watch started at.
|
||||
- **Get State and Start at Any:** Warning: Watches initialize this way may return arbitrarily stale data! Please review this semantic before using it, and favor the other semantics where possible. Start a watch at any resource version, the most recent resource version available is preferred, but not required; any starting resource version is allowed. It is possible for the watch to start at a much older resource version that the client has previously observed, particularly in high availabiliy configurations, due to partitions or stale caches. Clients that cannot tolerate this should not start a watch with this semantic. To establish initial state, the watch begins with synthetic “Added” events for all resources instances that exist at the starting resource version. All following watch events are for all changes that occured after the resource version the watch started at.
|
||||
- **Start at Exact:** Start a watch at an exact resource version. The watch events are for all changes after the provided resource version. Unlike "Get State and Start at Most Recent" and "Get State and Start at Any", the watch is not started with synthetic "Added" events for the provided resource version. The client is assumed to already have the initial state at the starting resource version since the client provided the resource version.

### "410 Gone" responses
|
||||
|
||||
Servers are not required to serve all older resource versions and may return a HTTP `410 (Gone)` status code if a client requests a resourceVersion older than the server has retained. Clients must be able to tolerate `410 (Gone)` responses. See [Efficient detection of changes](#efficient-detection-of-changes) for details on how to handle `410 (Gone)` responses when watching resources.
|
||||
|
||||
For example, the kube-apiserver periodically compacts old resource versions from etcd based on its `--etcd-compaction-interval` setting. Also, the kube-apiserver's watch cache keeps `--watch-cache-sizes` resource versions in each resource cache. It depends on if a request is served from cache on which one of these limits applies, but if a resource version is unavailable in the one that applies, a `410 (Gone)` will be returned by the kube-apiserver.
