The Instantiated state may be re-invoked to start a new set of rsync resources  and cluster resources.

AppContext State

The rsync process will maintain a top level state for the AppContext.  The states are:

  • Instantiating:  Once rsync is invoked to instantiate an AppContext, the state will be set to Instantiating.
  • InstantiatedRsyinc will set the .AppContext state to Instantiated after all Resources in the AppContext have been Applied.
  • InstantiateFailed:  This indicates that one or more Resources Failed to be applied.
  • Terminating:  When terminate is invoked, this state will be entered directly if the AppContext is in Instantiated or InstantiateFailed state.  If a previous Instantiating sequence is still running, the transition process includes shutting down the instantiating sequence before entering the Terminating state.
  • Terminated:  This indicates that rsync has successfully Deleted all resources.
  • TerminateFailed:  This indicates that rsync has received a failure response from one or more Resources when attempting to delete them.  

Rsync resource state values

The state of the rsync resource is maintained in the EMCO AppContext by rsync.  The status values are defined as follows.

  • Pending:  Upon initial creation by ncm (for cluster network intents) or orchestrator (for DIGs), the rsync resources will be initialized to a Pending status to indicate they have not been handled by rsync yet.
  • Applied:  This indicates that rsync has successfully applied the rsync resource to a destination cluster.  This does not indicate anything about the actual status of the corresponding cluster resource(s) - other than it is expected that the cluster resource does exist.
  • Failed:  This indicates that rsync has received a failure response when either attempting to apply or delete the rsync resource from the destination cluster.  rsync  is taking no further action with this resource.
  • Retrying:  This indicates that rsync is continuing to attempt to apply or delete the rsync resource from the destination cluster.  This may occur because connectivity to the destination cluster is currently unavailable, but may resume at a later time.  This will continue until a different lifecyle state is invoked on the controlling EMCO resource.
  • Terminated:  This indicates that rsync has successfully deleted the rsync resource from the destination cluster.  This does not indicate anything about the actual status of the corresponding cluster resource(s) - other than it is expected to that the cluster resource does exist or is in the process of terminating.

Cluster resource status

The status of resources deployed by rsync to clusters is detected as follows.

  1. When rsync instantiates rsync resources, it will also instantiate a ResourceBundleState CR to the cluster.  For a given Composite Application, a ResourceBundleState CR will be deployed for each App (in the Composite App) per cluster.  A label will be applied by rsync to all cluster resources of a given App and will be matched by label to the corresponding ResourceBundleState CR in the cluster.  The label format is:  "emco/deployment-id: <AppContext identifier>-<app-name>"
  2. A 'monitor' pod is present in each cluster is monitors all resources with the "emco/deployement-id" label.  When it detects changes to those resources, it will update the matching ResourceBundleState CR with the details of the resource.  In the example ResourceBundleState CR below, for example, all pod resources that are labeled with emco/deployment-id: 171887448792644816-sink will be included in the 'podStatuses' array.
  3. A Watcher thread is started per cluster by rsync to watch for changes to ResourceBundleState CRs in the cluster.  When an updated CR is detected, the Watcher retrieves it and saves it into the corresponding AppContext per App/Cluster so it is available to provide information for cluster resource queries.

The cluster resource  status is provided in two forms.

  1. The actual status{} portion of the cluster resource (if present) is made available in the information returned via the ResourceBundleState CR.
  2. Summarized in a value as follows.
    • Unknown:  The unknown status represents the case where a ResourceBundleState CR has not been received yet, or that the ResourceBundleState CR does not  support that resource type.
    • NotPresent:  For resource types (Kinds) that are supported by the ResourceBundleState CR, if an rsync resource does not have a corresponding cluster resource in the CR, then the cluster status of the resource is NotPresent.
    • Present: For rsync resources with a corresponding cluster resource in the ResourceBundleState CR, the clustesr status is present.
    • TBD: Further work can be done to summarize the Status{} portion of cluster resources to identify the status more precisely than Present - such as: Active, Ready, Not Ready, etc.

Status Query Sequence

This illustrates a status query sequence

Status Query

The status query, and variations with query parameters, on an EMCO resource will present the information described previously to the caller.  The basic status query for the two EMCO resources discussed above will look like the following:

URL:  GET /v2/cluster-providers/{cluster-provider-name}/clusters/{cluster-name}/status

URL:  GET /v2/projects/{project-name}/composite-apps/{composite-app-name}/{version}/deployment-intent-groups/{deployment-intent-group-name}/status

The following query parameters will be available:

output=<summary | all | detail | rsync>

default output value is: 'all'

summary: will just show the top level EMC resource state and aggregated resource statuses but no resource detail information

all: will include a list of resources showing basic resource identification and resource statuses

detail: includes in the resource list the metadata, spec, and status of the resource as received in the ResourceBundleState CR

rsync: similar to detail, but only includes in the resource list the rsync resources - so the metadata and spec information will be taken from the AppContext.  No cluster status information will be included.

app=<appname>

default is all apps

This will filter the results of the query to show results only for the resources of the specified App(s).

cluster=<cluster>

default is all clusters

This will filter the results of the query to show results only for the specified cluster(s)

resource=<resource name>

default is all resources

This will filter the results of the query to show results only for the specified resource(s)

  • Instantiating:  Once rsync is invoked to instantiate an AppContext, the state will be set to Instantiating.
  • InstantiatedRsyinc will set the .AppContext state to Instantiated after all Resources in the AppContext have been Applied.
  • InstantiateFailed:  This indicates that one or more Resources Failed to be applied.
  • Terminating:  When terminate is invoked, this state will be entered directly if the AppContext is in Instantiated or InstantiateFailed state.  If a previous Instantiating sequence is still running, the transition process includes shutting down the instantiating sequence before entering the Terminating state.
  • Terminated:  This indicates that rsync has successfully Deleted all resources.
  • TerminateFailed:  This indicates that rsync has received a failure response from one or more Resources when attempting to delete them.  



Rsync resource state values

The state of the rsync resource is maintained in the EMCO AppContext by rsync.  The status values are defined as follows.

  • Pending:  Upon initial creation by ncm (for cluster network intents) or orchestrator (for DIGs), the rsync resources will be initialized to a Pending status to indicate they have not been handled by rsync yet.
  • Applied:  This indicates that rsync has successfully applied the rsync resource to a destination cluster.  This does not indicate anything about the actual status of the corresponding cluster resource(s) - other than it is expected that the cluster resource does exist.
  • Failed:  This indicates that rsync has received a failure response when either attempting to apply or delete the rsync resource from the destination cluster.  rsync  is taking no further action with this resource.
  • Retrying:  This indicates that rsync is continuing to attempt to apply or delete the rsync resource from the destination cluster.  This may occur because connectivity to the destination cluster is currently unavailable, but may resume at a later time.  This will continue until a different lifecyle state is invoked on the controlling EMCO resource.
  • Terminated:  This indicates that rsync has successfully deleted the rsync resource from the destination cluster.  This does not indicate anything about the actual status of the corresponding cluster resource(s) - other than it is expected to that the cluster resource does exist or is in the process of terminating.



Cluster resource status

The status of resources deployed by rsync to clusters is detected as follows.

  1. When rsync instantiates rsync resources, it will also instantiate a ResourceBundleState CR to the cluster.  For a given Composite Application, a ResourceBundleState CR will be deployed for each App (in the Composite App) per cluster.  A label will be applied by rsync to all cluster resources of a given App and will be matched by label to the corresponding ResourceBundleState CR in the cluster.  The label format is:  "emco/deployment-id: <AppContext identifier>-<app-name>"
  2. A 'monitor' pod is present in each cluster is monitors all resources with the "emco/deployement-id" label.  When it detects changes to those resources, it will update the matching ResourceBundleState CR with the details of the resource.  In the example ResourceBundleState CR below, for example, all pod resources that are labeled with emco/deployment-id: 171887448792644816-sink will be included in the 'podStatuses' array.
  3. A Watcher thread is started per cluster by rsync to watch for changes to ResourceBundleState CRs in the cluster.  When an updated CR is detected, the Watcher retrieves it and saves it into the corresponding AppContext per App/Cluster so it is available to provide information for cluster resource queries.

Status Query

The status query, and variations with query parameters, on an EMCO resource will present the information described previously to the caller.  The basic status query for the two EMCO resources discussed above will look like the following:

URL:  GET /v2/cluster-providers/{cluster-provider-name}/clusters/{cluster-name}/status

URL:  GET /v2/projects/{project-name}/composite-apps/{composite-app-name}/{version}/deployment-intent-groups/{deployment-intent-group-name}/status


The following query parameters will be available:

type=<rsync | cluster>

default type is 'rsync'

rsync: gathers status based on the rsync resources.

cluster: gathers status based on cluster resource information received in the ResourceBundleState CRs received from the cluster(s)

output=<summary | all | detail >

default output value is: 'all'

summary: will just show the top level EMCO resource state and status along with aggregated resource statuses but no resource detail information

any filters added will affect the aggregated resource status results, although resource details will not be displayed

all: will include a list of resources, organized by App and Cluster, showing basic resource identification (Group Version Kind) and resource statuses

detail: includes in the resource list the metadata, spec, and status of the resource as received in the ResourceBundleState CR


The following query parameters filter the results returned.  Aggregated status results at the top level are relative to the filter parameters supplied

app=<appname>

default is all apps

This will filter the results of the query to show results only for the resources of the specified App(s).

cluster=<cluster>

default is all clusters

This will filter the results of the query to show results only for the specified cluster(s)

resource=<resource name>

default is all resources

X


              "rsync-status": "[ Pending | Instantiated | Failed | Retrying |Terminated ]",

"Pending" - is set by orchestrator before issuing an Instantiate command to rsync

"Instantiate" - means rsync has successfully invoked deployment of the resource to the cluster

"Failed" - means rsync got an explicit failure when invoking to the cluster

"Retrying" - means connection to cluster is temporarily unavailable, rsync will continue to retry - applies to both instantiate and terminate sequences (initial thought is to detect this condition at a cluster level - but mark each resource)

"Terminated" - means rsync has successfully invoked termination of the resource to the cluster


X

X

X

              "cluster-status": "[ Unknown | NotPresent | Present | (tbd) ]"

Currently not include in 'cluster' type queries - any resource shown is inherently 'Present'

Summary status for the resource from info obtained from the cluster (e.g. via the ResourceBundleState CR)

"Unknown" - means a ResourceBundleState has not yet been received or the resource type is not supported in the ResourceBundleState CR

"NotPresent" - the resource is not in the ResourceBundleState CR and it is supported.

"Present" - the resource is present in the ResourceBundleState CR

"tbd" - further status values can be derived as analysis of how to represent the full status {} object from the resource can be interpreted - e.g. 'Ready', 'Failed', 'Pending', etc.

Concept for query of historical instances EMCO resources

Once an EMCO resource has been instantiated and terminated. It may be instantiated again.  On termination, it is possible to save the AppContext of the old instance so that it can be
