Modifies the fsCache to support a list of arbitrary kubernetes objects instead of just one pod. This allows better support for the newdeploy backend.
Also removes the byKubeObject cache index; cleanup is changed to use the byFunction index, and byKubeObject is no longer needed.
A few improvements to the integration test:
* Search for test files recursively in the test dir
* Output a test report at the end for a quick summary of what tests passed/failed/were skipped
* Add support skipping test files; skip the logging test since it's broken (#446 is tracking this)
* Switch to latest helm version
* Cleanup namespace
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
Add package command support: This PR adds package command to CLI. package provides some useful subcommands to use such as packages CRUD and display package detail information. Also it is able to reuse existing package at function creation.
* Check function existence before creating package
* Check package existence
* Add support for downloading archive from given url
The functionality was supported before e238776bf7. Add this functionality back for more flexible usage.
* Add output flag to save archive content in specific file
* Add logs when package create/update
* Fix fnCreate requires environment argument when a pkg is specified
* Fix fnUpdate failed to update function pkg info when a package is specified
* Add package command test
* Fix wrong python test image in test script
* Remove package description fields
* Fix package command not update package but creating a new one
* Set package as pending status only when there is no deploy archive
* Rename function from fetchArchiveFromArbitraryURL to downloadToTempFile
* Use io.Copy to prevent loading all body into memory
* Revise some messages
* Allow user to update package build command
* Allow user to update package content when using function update
* Retrieve pkgName from function packageref if it’s not specified
* Fix function failed to update due to resource conflict
* Fix test case failure due to single quote
* kick ci
* Fix failed to update function packageRef
* kick ci
* kick ci
Before this change, poolmgr tried to hit fetcher just once. However if the pod has just started, fetcher may not be up yet, causing the initial request to fail with a connection refused error. This change adds a similar retry loop that we currently use on the specialize endpoint of the runtime environment container.
Create a container image with the buidler, so we can avoid copying the builder binary into the env container during the env container build.
Gather both stdout and stderr of a build into the logs.
* Add Dockerfile for builder + update release scripts
* Improve logging of buildermgr and builder
* Add support for environment-scoped buildcmd
* Fix fork/exec wd when package is a file
* Update tests to also include builder image
* Add logging to builder's fork/exec
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
Remove the `logger` container from the logging daemonset.
Remove the outgoing call from the poolmgr to the logger. Use Fluentd's Kubernetes filter to add function name and UID to influx metadata.
This means fluentd now figures out when to start collecting function logs on its own, without being informed by poolmgr. This is great for other execution strategies, and for autoscaling, where fission isn't in direct control of function pod creation.
Also adds an integration test to make sure logging keeps working.
This fixes a bug where functionReferenceResolver returned out-of-date function metadata and caused the router to proxy requests to old function pods.
It also uses the go context package to shutdown the controller when the router is shutting down.
