Improved some of warnings/messages shown to the user when using `fission spec` command. The `spec validate` command now shows appropriate warnings instead
This line warns the user that dependent environment doesn’t exist, and presents the command line
for creating an environment.
When the variable `envNamespace` is specified, the `envns` option should be available as well.
This feature allows creation of fission objects in different namespaces, in addition to retaining the existing behavior of creating fission objects in default namespace if user doesnt provide one.
It also removes cluster admin roles for fission-fetcher and fission-builder Service Accounts and grants them only those privileges that they need.
* Fixes the issue with fn test and adds relevant test cases, fixes#650
* Checking log size for invalid function
* Testing the invalid function logs a few time beforr quitting
* Disabling the test for now, linked to issue #653
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.
setting serviceType to ClusterIP as default for fission controller and corresponding changes in fission cli to be able to port-forward the controller pod.
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.

* 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.
Introduce _Archives_ as a type to reference arbitrary blobs.
_Packages_ are a pair of Source and Deployment archives. Packages have an environment reference.
Functions reference a package. Multiple functions can reference the same package.
This change contains CLI support for uploading large functions to the storage service.
It also adds a reverse proxy into the storage service to the fission API.
The helm chart is not yet updated to actually run the storage service -- that will come in the next change.
Split out the Package type into a first class Kubernetes resource. Before this change, packages were implicitly tied to functions.
This wasn't ideal because:
* Functions will need to share packages
* A package storage system may be more generally useful than just
functions (for example, for storing static assets)
This change does the following:
* Updates the fission and tpr types to add a new Package and PackageSpec. It also creates a PackageRef type, and a FunctionPackageRef type. The PackageRef simply references a package, but the FunctionPackageRef includes the name of a function within the package. This allows us to share packages between different functions.
* Updates fetcher and other components for first-class packages
* Allows customization of fetcher image pull policy in the helm charts
This changes the core fission function, environment and trigger types. It also changes Fission's storage to use ThirdPartyResources.
- Functions are now specified by packages. Functions can also have both source and deployment packages. A package can be specified by a literal, or by a URL.
- Environments have a build and runtime component.
- Triggers reference functions by a FunctionReference. This is a layer of indirection between triggers and functions, and will allow things like incremental function upgrades in future releases.
See Documentation/wip/env-v2.md for design discussion about points 1 and 2.
Changes:
* V2 Types
All types now have a spec, following the pattern of K8s objects.
Functions now have source and deployment packages. A Package can be
specified by literal, or by URL.
Environments now have a builder and runtime component.
All triggers use a new FunctionReference to specify the function. This
for now only uses a function name, but in the future can be extended
to be more flexible.
A new FunctionLoadRequest type is added for specialization requests to
the environment runtime.
* TPR types, TPR init code, and a "fission client"
Implements TPR types using the spec types in fission/types.go.
Adds code for adding creating TPR types, and convenient types for crud
operations on each of our resource types.
Adds code for connecting to K8s API and configuring a REST client with
fission types set up.
* Change old stateful controller into a thin apiserver
This apiserver is now simply a stateless api layer on top of the TPR
types. At the moment it doesn't do anything that couldn't be done by
simply talking to the TPR types. In the future we can have better
validation and potentially some higher level APIs (like versioning for
example) in here.
* Split controller client into files and update for v2 types.
* Update CLI for v2 types.
As far as possible we keep the CLI flags the same. We'll have to add
flags for source/deploy packages and builder/runtime
environments. That will come in the next change.
* Update poolmgr and fetcher for v2 types.
Also adds a poolmgr_test.
* Update router for new types.
Also adds a function reference resolver, which separates out the job
of resolving a FunctionReference to a function.
* Update kubewatcher and timer for v2 types.
* Update Message Queue trigger type for v2 types.
* Minor odds and ends.
* Fission bundle CLI updates
Remove controllerUrl flag, since we don't need it any more.
* Remove etcd deployment (replaced by storing state in TPR)
Also update the poolmgr commandline, and use an env var for the
fetcher image URL.
* Explicit ChecksumType and consts
* Clarify separation of environment interface types
Establish a proxy server from the controller to the log database.
Redirect query commands send from client to database then proxy back the db response.
Use parameter binding instead of fmt.Sprintf to prevent SQL injection.
Add function log aggregation and persistence using Fluentd and InfluxDB.
Fluentd and a helper sidecar run as a daemonset. The poolmgr sets up logging for each function pod, using the helper sidecar. Fluentd forwards logs to InfluxDB, which is run as a deployment and service. The client CLI directly queries InfluxDB for logs.
Fluentd supports many outputs besides InfluxDB, so we aren't very tied to InfluxDB.
The setup is somewhat manual, which we should be able to improve by integrating this into the helm chart.

Minimal golang runtime.
Functions are built as Go plugins, and the plugin is uploaded to fission.
See `environments/go/README.md` for instructions and `examples/go` for a usage example.
For now, we're re-using the 'code' field of the function to store the binary plugin. With v2 environments, this will be stored separately as a binary package.
This allows users to add --method and --url params to their "fission
fn create" command line. It sets up the route to call the latest
version of the function; user can edit the route with the "fission
route update" command, if they want to.
The new command invokes editor on a copy of the source code, and
uploads the new source code. It's an easy way to manually edit
functions from a terminal.
