Introducing Multitracker!
Introducing Multitracker!
Multitracker aimed to track multiple resources at the same time. Resources configured using MultitrackSpecs structure:
type MultitrackSpecs struct {
Deployments []MultitrackSpec
StatefulSets []MultitrackSpec
DaemonSets []MultitrackSpec
Jobs []MultitrackSpec
}
Each resource is specified using MultitrackSpec structure:
type MultitrackSpec struct {
ResourceName string
Namespace string
FailMode FailMode
AllowFailuresCount *int
FailureThresholdSeconds *int
LogRegex *regexp.Regexp
LogRegexByContainerName map[string]*regexp.Regexp
SkipLogs bool
SkipLogsForContainers []string
ShowLogsOnlyForContainers []string
ShowLogsUntil DeployCondition
SkipEvents bool
}
Multitracker introduces fail-modes: IgnoreAndContinueDeployProcess, FailWholeDeployProcessImmediately and HopeUntilEndOfDeployProcess. Fail mode can be configured per-resource to completely ignore resource errors or ignore errors till all of the tracked resources become ready.
Only ResourceName and Namespace are required fields of MultitrackSpec.
Multitrack cli
There is minimal viable support of multitracker in kubedog cli. To use multitracker user must pass to kubedog stdin json structure which resembles golang structure MultitrackSpecs, for example:
cat << EOF | kubedog multitrack
{
"StatefulSets": [
{
"ResourceName": "mysts1",
"Namespace": "myns"
}
],
"Deployments": [
{
"ResourceName": "mydeploy22",
"Namespace": "myns"
}
]
}
EOF
Deprecation of rollout and follow trackers
BRIEF: users of rollout tracker should migrate to multitracker, users of follow tracker can continue using follow tracker.
Old trackers will remain in the source code and cli. But these trackers will not receive future support. The reason is: multitracker solves main kubedog in the more common way.
NOTE: Multitracker for now does not have follow-mode, it only works in rollout-mode (e.g. tracks resources until resources are ready). If you need follow mode, you can use old follow tracker for now. In the future multitracker will be configurable to run in either rollout or follow mode (in the follow mode multitracker should print info forever).
