Adds a validator, invoked through `fission spec validate` and before `fission spec apply`. The validator checks for duplicate names, dangling references, and unused resources.
Also attempts to fix a race between CLI and builder. Avoids replacing a package while it's building, instead waiting for the build status to change from pending before updating it.
The cli spec dir flag name should be `specdir`, not `specs`, that should match to:
```go
specDirFlag := cli.StringFlag{Name: "specdir", Usage: "Directory to store specs, defaults to ./specs"}
```
in fission/main.go
Currently it cause the specific specs dir not to work.
```
$ fission spec apply --specdir <my spec dir>
Everything up to date.
```
Remove the hard coded default "fission" namespace that was added in the last PR, replacing it with some logic to figure out where fission is installed and connecting to it if there's exactly one installation. If there is more than one fission installation, error out with a useful message.
Also improve the error message for a missing kubeconfig file.
This makes set up easier for new users. Users can still set
FISSION_NAMESPACE but it will default to "fission". Users can also
still set KUBECONFIG, but it will default to $HOME/.kube/config.
Also, update the post-install chart notes.txt and the install guide to
use "fission function test" as the first step after install. This
means that if there's anything wrong with the setup, the user will see
useful errors instead of "internal server error". Also, they can test
their setup without worrying about nodeports or ingresses or whatever.
All existing functionality of FISSION_URL and FISSION_ROUTER continues
to work.
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.
* prevent leaking packages; add new clis to list and delete orphan packages.
* Fixes after testing.
* Address review comment.
* Removing deleting orphan packages from fnUpdate and fnDelete.
* goFmt and removing unwanted code.
These commits implement support for consuming messages from an Azure storage queue to trigger Fission functions.
* Add stubbed Azure message queue implementation and modify Helm charts.
This commit stubs an implementation for an Azure storage message queue trigger
that will be completed by future commits.
It also modifies the Helm chart to add support for deploying Fission with an
mqtrigger configured for Azure storage queue triggers.
* Add Azure Go SDK to glide.
This commit adds the Azure Go SDK to glide for the upcoming work to support
Azure storage queue triggers.
* Implement Azure message queue trigger.
This commit implements a message queue trigger based on Azure storage queues.
Required message queue trigger manager environment variables:
* AZURE_STORAGE_ACCOUNT_NAME - the Azure storage account to use.
* AZURE_STORAGE_ACCOUNT_KEY - the Azure storage account key.
When creating a message queue trigger, the topic will be the Azure storage
queue to receive messages from.
* Add CA certificates to fission-bundle.
This commit adds the root CA certificates to the fission-bundle image. This
allows Fission to contact third-party APIs that use HTTPS with root CA
signed certificates.
* Add Makefile to build and test.
This commit adds a simple Makefile for building the client and bundle, running
tests, creating the Docker image, and pushing the Docker image.
This change enables users to have declarative specifications for Fission resources. Users can specify their "app" in a set of spec files, and use a new fission CLI command to "apply" these specs to a running cluster.
The new "spec" CLI also includes archiving of local source files, and a file watcher that re-builds archives and uploads them on file changes, and a package build watcher that waits for package builds on the CLI.
A "--spec" option is also added to "function create", and will be added to other resources in future changes. This option causes a YAML to be outputted to the specs directory instead of the resource being created on the cluster.
The CLI "fission spec --help" outputs usage information.
This commit solves part of the issue #52 , functions are able to access secrets/configmaps specified by the user. For now, CLI only accept one secret/configmap. For advanced users, it will be able to use YAML to declare multiple secrets/configmaps in later changes.
A newdeploy backend which uses new deployment to serve requests. This is the second phase of #193 and builds on top of changes in #384 .

* Separating the executor vs. poolmgr backend functionality and associated data members

* 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
* Fetcher called when pod is created for newDeploy backend but also supports older way, this is WIP and still needs pod specialization and creating & exposing a service so the URL can be hit by end user
* WIP Specializing the POD as part of startup along with fetching
* Working specialization of a new deployment. Needs some work on caching, cleanup etc.
* Switched to service based address instead of POD address
* Minor formating issue fixed

* Fixed some rebase issues that were failing build
* Better names for K8S objects and methods

* Removed stale executor service & deployment from previous merge
* Addressed review comments, still testing some areas
* Added types in FunctionSpec
* Resolved conflicts due to merge from executor_abstraction branch

* Moved instanceIdLabel to types to avoid cyclic dependency
* More review fixes
* Tweaking sleep to see results
* If user does not provide poolsize, then it should not default to zero
* Switched to naming convention for now, fixed default poolsize if not provided
* Changed error return behaviour in delete fn, also changed cleanup to look based on obj type though support for additional type will need more work
* Changed check location so avoid false logging
* Test for newdeploy backend
* Adding tests for poolmgr backend
* Fixed an issue with glide dependency version, already fixed in master

* Changed name from 'backend' to executorType, added additional test for minscale 0 case, changed TargetCPU to TargetCPUPercent
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.

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 contains a few different builder manager fixes:
* Update the zip file structure to avoid an extra subdirectory
* Annotate packages with what functions are using them
* Only trigger builds when there is no deployment archive
* Python environment loadpath bugfixes
* Other bugfixes
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.
This change orchestrates function builds.
Environments (in v2) define a builder image, just like they do a runtime image. The builder image contains a build script that's invoked with source and deployment paths (as env vars).
The buildermgr watches for environments with build images defined, and creates build deployments and services.
Functions can define source and deployment. Buildermgr watches for functions with source code (and build status == pending) and invokes the environment's builder when appropriate. It captures logs from the build and sets the build status (success/failure) and build lots into the PackageStatus.
Allows dumping v0.1 state to a json file and restoring it into a new v0.2.1 fission installation.
