# kstatus
|
||||
|
||||
kstatus provides tools for checking the status of Kubernetes resources. The primary use case is knowing when
|
||||
(or if) a given set of resources in cluster has successfully reconciled an apply operation.
|
||||
|
||||
## Concepts
|
||||
|
||||
This effort has several goals, some with a shorter timeline than others. Initially, we want to provide
|
||||
a library that makes it easier to decide when changes to a set of resources have been reconciled in a cluster.
|
||||
To support types that do not yet publish status information, we will initially fallback on type specific rules.
|
||||
The library already contains rules for many of the most common built-in types such a Deployment and StatefulSet.
|
||||
|
||||
For custom resource definitions (CRDs), there currently isn't much guidance on which properties should be exposed in the status
|
||||
object and which conditions should be used. As part of this effort we want to define a set of standard conditions
|
||||
that the library will understand and that we encourage developers to adopt in their CRDs. These standard conditions will
|
||||
be focused on providing the necessary information for understanding status of the reconcile after `apply` and it is not
|
||||
expected that these will necessarily be the only conditions exposed in a custom resource. Developers will be free to add as many conditions
|
||||
as they wish, but if the CRDs adopt the standard conditions defined here, this library will handle them correctly.
|
||||
|
||||
The `status` objects for built-in types don't all conform to a common behavior. Not all built-in types expose conditions,
|
||||
and even among the types that does, the types of conditions vary widely. Long-term, we hope to add support for the
|
||||
standard conditions to the built-in types as well. This would remove the need for type-specific rules for determining
|
||||
status.
|
||||
|
||||
### Statuses
|
||||
|
||||
The library currently defines the following statuses for resource:
|
||||
* __InProgress__: The actual state of the resource has not yet reached the desired state as specified in the
|
||||
resource manifest, i.e. the resource reconcile has not yet completed. Newly created resources will usually
|
||||
start with this status, although some resources like ConfigMaps are Current immediately.
|
||||
* __Failed__: The process of reconciling the actual state with the desired state has encountered and error
|
||||
or it has made insufficient progress.
|
||||
* __Current__: The actual state of the resource matches the desired state. The reconcile process is considered
|
||||
complete until there are changes to either the desired or the actual state.
|
||||
* __Terminating__: The resource is in the process of being deleted.
|
||||
* __Unknown__: This is for situations when the library are unable to determine the status of a resource.
|
||||
|
||||
### Conditions
|
||||
|
||||
The conditions defined in the library are designed to adhere to the "abnormal-true" pattern, i.e. that
|
||||
conditions are present and with a value of true whenever something unusual happens. So the absence of
|
||||
any conditions means everything is normal. Normal in this situation simply means that the latest observed
|
||||
generation of the resource manifest by the controller have been fully reconciled with the actual state.
|
||||
|
||||
* __InProgress__: The controller is currently working on reconciling the latest changes.
|
||||
* __Failed__: The controller has encountered an error during the reconcile process or it has made
|
||||
insufficient progress (timeout).
|
||||
|
||||
The use of the "abnormal-true" pattern has some challenges. If the controller is not running, or for some
|
||||
reason not able to update the resource, it will look like it is in a good state when that is not true. The
|
||||
solution to this issue is to adopt the pattern used by several of the built-in types where there is an
|
||||
`observedGeneration` property on the status object which is set by the controller during the reconcile loop.
|
||||
If the `generation` and the `observedGeneration` of a resource does not match, it means there are changes
|
||||
that the controller has not yet seen, and therefore not acted upon.
|
||||
|
||||
## Features
|
||||
|
||||
The library is currently separated into two packages, one that provides the basic functionality, and another that
|
||||
builds upon the basics to provide a higher level API.
|
||||
|
||||
**sigs.k8s.io/kustomize/kstatus/status**: Provides two basic functions. First, it provides the `Compute` function
|
||||
that takes a single resource and computes the status for this resource based on the fields in the status object for
|
||||
the resource. Second, it provides the `Augment` function that computes the appropriate standard conditions based on
|
||||
the status object and then amends them to the conditions in the resource. Both of these functions currently operate
|
||||
on Unstructured types, but this should eventually be changed to rely on the kyaml library. Both of these functions
|
||||
compute the status and conditions solely based on the data in the resource passed in. It does not communicate with
|
||||
a cluster to get the latest state of the resources.
|
||||
|
||||
**sigs.k8s.io/kustomize/kstatus/wait**: This package builds upon the status package and provides functionality that
|
||||
will fetch the latest state from a cluster. It provides the `FetchAndResolve` function that takes list of resource
|
||||
identifiers, fetches the latest state for all the resources from the cluster, computes the status for all of them and
|
||||
returns the results. `WaitForStatus` accepts a list of resource identifiers and will poll cluster for the status of
|
||||
the resources until all resources have reached the `Current` status.
|
||||
|
||||
## Challenges
|
||||
|
||||
### Status is not obvious for all resource types
|
||||
|
||||
For some types of resources, it is pretty clear what the different statuses mean. For others, it
|
||||
is far less obvious. For example, what does it mean that a PodDisruptionBudget is Current? Based on
|
||||
the assumptions above it probably should be whenever the controller has observed the resource
|
||||
and updated the status object of the PDB with information on allowed disruptions. But currently, a PDB is
|
||||
considered Current when the number of healthy replicas meets the threshold given in the PDB. Also, should
|
||||
the presence of a PDB influence when a Deployment is considered Current? This would mean that a Deployment
|
||||
should be considered Current whenever the number of replicas reach the threshold set by the corresponding
|
||||
PDB. This is not currently supported as described below.
|
||||
|
||||
### Status is decided based on single resource
|
||||
Currently the status of a resource is decided solely based on information from
|
||||
the state of that resource. This is an issue for resources that create other resources
|
||||
and that doesn't provide sufficient information within their own status object. An example
|
||||
is the Service resource that doesn't provide much status information but do generate Endpoint
|
||||
resources that could be used to determine status. Similar, the status of a Deployment could be
|
||||
based on its generated ReplicaSets and Pods.
|
||||
|
||||
Not having the generated resources also limits the amount of details that can be provided
|
||||
when something isn't working as expected.
|
||||
|
||||
|
||||
## Future
|
||||
|
||||
### Depend on kyaml instead of k8s libraries
|
||||
The sigs.k8s.io/kustomize/kstatus/status package currently depends on k8s libraries. This can be
|
||||
challenging if someone wants to vendor the library within their own project. We want to replace
|
||||
the dependencies on k8s libraries with kyaml for the status package. The wait package needs to
|
||||
talk to a k8s cluster, so this package will continue to rely on the k8s libraries.
|
||||
|
||||
### Use watches instead of polling
|
||||
|
||||
We currently poll for updates to resources, but it would be possible to set up
|
||||
watches instead. This could also be combined with deciding status based on not only a single
|
||||
resource, but also all its generated resources. This would lead to a design that seems similar
|
||||
to a controller, so maybe a solution like this could be built on top of controller-runtime.
|
||||
A challenge here is that the rules for each built-in type would need to be expressed in a different
|
||||
way that what we currently do.
