* Use terraform to manage ci cluster. Upgrade ci cluster to 1.13
* Upgrade helm version
* Do not break the test if no previous resources
* Do not skip install helm if helm is old version
This removes fluentd in favor of using fluentbit, which is lighter (in
memory usage) and seems to be more actively maintained.
Fluentbit's config file format is different from fluentd's. It also
doesn't support the same record modification stuff that fluentd
supports, so we have to change the influxdb query slightly. This
means that after an upgrade, the new CLI may won't work for querying older
logs. Hopefully, this slight breakage is acceptable; if users
really need older logs they can use the older CLI.
This change adds a layer of abstraction over poolmgr. Poolmgr is now just one of the ways to turn a function into a service; other implementations will be added. The executor abstraction is a uniform API over all these implementations.
* Executor layer added on top of pool manager
* Removed the external server for executor
* Minor changes to keep existing semantics as much possible
* Separating the executor vs. poolmgr backend functionality and associated data members
* Executor logic separated from Poolmgr backend completely, placeholder for new backend
* Changed references to poolmgr in tests
* Moved poolmgr to it's package, as a side effect moved Cache to its's package (was causing cyclical dependency) and had to make some data structures exposed outside package
* Rebased from master and changed references to tpr -> crd
* Executor layer added on top of pool manager
* Executor logic separated from Poolmgr backend completely, placeholder for new backend
* Changed podName to a generic objectReference in fscache (#391)
Changed podName to a generic objectReference in function service cache implementation.
* Moved poolmgr to it's package, as a side effect moved Cache to its's package (was causing cyclical dependency) and had to make some data structures exposed outside package
* Rebased from master and changed references to tpr -> crd
* Merged from master with latest changes
* Removed stale executor service & deployment from previous merge
* Addressed review comments, still testing some areas
Switch Fission's storage over to the new CustomResourceDefinitions, from the deprecated ThirdPartyResources. This allows us to be compatible with Kubernets 1.8 and onwards.
This also adds a CLI tool for dumping state from an old fission version and restoring state into new CRDs.
The storage service is unaffected by this change.
Travis doesn't pass secret env vars to tests run on forks, so we need
a way to skip the tests when there are no credentials passed in.
This change unsets KUBECONFIG when there's no reachable cluster. The
Go tests already check for KUBECONFIG and skip when it's not defined.
Sets up Travis CI tests to use a Kubernetes cluster on GKE. All tests have access to $KUBECONFIG which points at a kubeconfig file with credentials to a cluster.
I had to skip the poolmgr unit test because it currently assumes NodePort services; that will be fixed in another change.
Also, because some of the tests don't work properly in parallel, I've ended up reducing the concurrency to 1. If this becomes a problem we'll have to fix the tests, but for now I don't mind just waiting a few minutes longer.
