Jaeger preserves the trace data of router healthz endpoints
which is not so helpful for monitoring function metrics and
consumes storage to store such trace data.
This PR uses `GetStartOptions` to examine the request's path and
check if it's a request to healthz endpoint. If yes, skip and not
to trace it.
Helm treats the single line "extraCoreComponentPodConfig" in
values.yaml as a key value pair config.
```
extraCoreComponentPodConfig:
```
And when a user tries to install helm with providing config
like following, it failed.
```
extraCoreComponentPodConfig:
nodeSelector:
serverless: fission
```
The root cause is that helm treats config in default values.yaml
and providing config as two different types of config, which is
key-value vs. value table. And so it's unable for helm to merge these
two configs even with the same key name.
This PR comments out the single line config in default values.yaml
to prevent the issue.
Encoded path means the URL path contains encoded string like "/foo%2Fbar".
Gorilla/Mux by default doesn't enable encoded path support, you need to enable
it when initializing the router.
This PR adds a new environment variable USE_ENCODED_PATH to the router
deployment to enable encoded path support.
ReplicaSet generated by Deployment distributes pods to nodes based
on nodes resource usage, which means in some cases the newly created
pods may be assigned to only a few nodes. The requests will go to the
same node if there multiple pods on it and may increase the node
resource usage and overall request latency.
To solve the problem mentioned above, this PR allows users to deploy
the router as DaemonSet so that we can distribute requests across all
nodes for better workload distribution and lower latency.
This fix allows the empty repository tag in values.yaml file. The changes are done in the templates of deployment and fluentbit where repository tag will be added in the docker image name only when specified with some value in case of empty repository tag image name contain the name of image and tag only.
* Add support for setting nodeSelector/affinity/tolerations on all deployments of fission components.
* Add extraCoreComponmentPodConfig helm value to allow setting of affinty/tolerations/nodeSelectors/etc on core pods
It is mandatory (from this release onwards) for function to refer to secrets, config-maps and packages in its own namespace to ensure isolation of users sharing the same cluster.
This change runs a pre-upgrade job to verify function references for all functions created prior to this release and fails the upgrade by printing a list of functions that violate this restriction.
This the very first step for fission to integrate with Istio, which is an open platform to connect, manage, and secure microservices. With Istio, users are able to monitor functions usage and trace requests latency through dashboards. For more information, please visit http://fission.io/docs/
setting serviceType to ClusterIP as default for fission controller and corresponding changes in fission cli to be able to port-forward the controller pod.
All functions have a pkg reference. This can be a package with either source and a deploy archives, or, a deploy archive. Everytime a function is updated, a new package is created. With archive pruner, the archives that are pointed to by old pkg reference can be deleted from the storage.
* High level spec for package pruning.
* Skeleton for archive pruning
* Adding meat 1 to skeleton.
* Adding meat #2. Separated storage service into a httpHandler component and
Storage Layer component.
* Adding meat #3. getOrphanedArchives in pruner and getItems on
stowClient.
* Restructured archivePruner methods.
* Commiting the day's work. Ready for testing #1.
* Fixing compile errors.
* Test ready. added a few logs for debugging.
* Adding a filter for getItems in stowClient.
* After testing.
* Added a test for archivePruner.
* Adding helm value pruneInterval for testing.
* Modified test.
* Final test.
* Fixing interval from seconds to minutes.
* Small change.
* Changing debugs to info.
* Removing the WIP design
* Ran gofmt on all these files.
* Fixing prune_interval as string in ENV var.
* Addressing all comments, but one.
* changing getFile method in stowClient to stream it into a response.
* All comments incorporated.
* Introducing a new flag for running archivePruner.
1. This flag is disabled for archivePruner to run in unit test.
2. This flag is enabled for archivePruner to run in production.
3. Also disabling test_archive_pruner.sh in this PR. Follow up with
next PR to enable it.
* Addressing review comments.
* Changing the command to generate a file dynamically.
* Enabling arching_pruner_test
* giving execute permissions to test_archive_pruner.sh
* Making changes of positional parameters after recent commit.
Change test case permission and removing kubectlPortForward.
* Adding debug to see why test_utils.sh passed junk pruneInterval.
* shell needs special handling for positional parameters from 10.
tested fission on openshift 3.7.0 and installed fine, without having to use openshift variables
those variables were used prior to switching to custom resource definitions, and as such are obsolete
