Fission 1.7.0-rc.2

Previously, once the executor is deleted for reasons (like upgrade or cluster scale-in),
the new executor deletes all existing resources created by the old executor and creates
new one. This mechanism becomes a problem when there are requests connecting to the
existing pods. Also in the worst case, the cluster may not have enough resources to create
new pods and cause service downtime.

This PR let each executor type adopts existing resources before starting the executor
API services, and so the alive connections won't experience failure. However, the requests
send to the function that doesn't have alive function pods will still fail due to the
executor is in bootstrapping.

+## Core Components
 
+### Controller
 
-Controller
-----------
+The controller contains CRUD APIs for functions, triggers, environments,
+Kubernetes event watches, etc. This is the component that the client talks to.
 
-The controller contains CRUD APIs for functions, http triggers,
-environments, Kubernetes event watches.  This is the component that
-the client talks to.
+All fission resources are stored in kubernetes CRDs. It needs to be able to
+talk to kubernetes API service.
 
-This is the only stateful component.  It needs to be configured with a
-URL to an etcd cluster and a path to a persistent volume.  The volume
-is used to store the functions' source code.  Etcd is used as the DB.
+### Executor
 
-[Work to extend to other storage backends is planned, see issue #83.]
+The executor has two simple APIs; the router calls both these endpoints.
 
-Pool Manager 
-------------
+* GetFunctionService takes function metadata and dispatches the corresponding executor 
+ type to get the address of a service/pod and returns it to the router.
+ 
+* TapService lets executor know a service/pod is being used; if it's not
+ called for a few minutes the pod(s) backing the service are killed.
 
-Poolmgr manages pools of generic containers and function containers.
+It now supports two different executor types:
 
-It has a simple API; both these endpoints are called by the router.
+* PoolManager
+* NewDeploy
 
-* GetFunctionService takes function metadata and returns the address
-  of a service.
-  
-* TapService lets poolmgr know a service is being used; if it's not
-  called for a few minutes the pod(s) backing the service are killed.
+These two executor types have different strategies to launch, specialize, and manage pod(s).
+You should choose one of the executor types wisely based on the scenario.
 
-Poolmgr watches the controller API and eagerly creates generic pools
-for environments.  It uses Kubernetes deployments to do that.  The
-environment container runs in a pod with the 'fetcher' container.
-Fetcher is a very simple utility that downloads a URL sent to it and
-saves it at a configured location.
+#### PoolManager 
 
-GetFunctionService "specializes" a pod.  The implementation chooses a
-pod from the pool, relabels it to "orphan" the pod from the
-deployment, invokes fetcher to copy the function into the pod, and
-hits the the specialize endpoint on the environment container.  This
-causes the function to be loaded.  The pod is now specific to that
-function.
+PoolManager manages pools of generic containers and function containers.
 
-This function pod is cached; it's cleaned up if it's unused for a few
-minutes.
+PoolManager watches the environment CRD changes and eagerly creates generic pools
+for environments. It uses Kubernetes deployments to do that. The 
+environment container runs in a pod with the 'fetcher' container. 
+Fetcher is a straightforward utility that downloads a URL sent to it 
+and saves it at a configured location (shared volume).
 
-Router
-------
+The implementation chooses a generic pod from the pool, relabels it to
+"orphan". The pod from the deployment invokes fetcher to copy the function 
+into the pod and hits the specialize endpoint on the environment container. 
+This causes the function to be loaded. The pod is now specific to that 
+function. This function pod is cached; it's cleaned up if it's unused for a few minutes.
 
-The router forwards HTTP requests to function pods.  If there's no
-running service for a function, it requests one from poolmgr, while
-holding on to the request; when the function's service is ready it
-forwards the request.
+PoolManager selects a generic pod from the warm pool, specializes it, 
+and recycles the pod if there are no further requests to the function after a few minutes.
+It makes PoolManager suitable for functions that are short-living
+and requires a short cold start time [1].
 
-The router is stateless and can be scaled up if needed, according to
+However, PoolManager only selects one pod per function, which is not
+suitable for serving massive traffic. In such cases, you should consider
+using NewDeploy as executor type of function.
+
+[1] The cold start time depends on the package size of the function. If it's
+a snippet of code, the cold start time usually is less then 100ms.
+
+#### NewDeploy 
+
+NewDeploy creates deployment, service, and HPA for functions in order to handle 
+massive traffic.
+
+NewDeploy watches the function CRD changes and creates a Kubernetes deployment, 
+service, and HPA for a function. NewDeploy will scale the replicas of a function 
+deployment to the minimum feasible scale setting, if the minimum scale setting of 
+a function is greater than 0. The 'fetcher' inside the pod uses a URL in the 
+JSON payload, which is attached as a parameter to start fetcher, to download the 
+function package instead of waiting for calls from NewDeploy. 
+
+When a function experiences a traffic spike, the service helps to distribute the requests to 
+pods belonging to the function for better workload distribution and lower latency. Also, 
+the HPA scales the replicas of the deployment based on the conditions set by the user.
+ 
+This approach though increases the cold time of a function, but also makes NewDeploy 
+suitable for functions designed to serve massive traffic.
+
+### Environment Container
+
+Environment containers run user-defined functions and are language-specific. 
+Each environment container must contain an HTTP server and a loader for functions.
+
+The pool manager deploys the environment container into a pod with fetcher 
+(fetcher is a simple utility that can fetch an HTTP URL to a file at a 
+configured location). This pod forms a "generic pod" because it can
+be loaded with any function in that coding language.
+
+When the pool manager needs to create a service for a function, it calls
+fetcher to fetch the function. Fetcher downloads the function into a
+volume shared between fetcher and this environment container. Poolmgr
+then requests the container to load the function.
+
+### Router
+
+The router forwards HTTP requests to function pods. If there's no
+running service for a function, it requests one from executor, while
+holding on to the request; the router will forward the request to 
+the pod once the function service is ready.
+
+The router is the only stateless component and can be scaled up if needed, according to
 load.
 
-Kubewatcher
------------
+### Builder Manager
+
+The builder manager watches the package & environments CRD changes and manages 
+the builds of function source code. Once an environment that contains a builder 
+image is created, the builder manager will then creates the Kubernetes service 
+and deployment under the fission-builder namespace to start the environment 
+builder. And once a package that contains a source archive is created, the 
+builder manager talks to the environment builder to build the function's source 
+archive into a deploy archive for function deployment.
+
+After the build, the builder manager asks Builder to upload the deploy archive to the 
+Storage Service once the build succeeded, and updates the package status attached with build logs.
+
+### Storage Service
+
+The storage service is the home for all archives of packages with sizes larger than 256KB.
+The Builder pulls the source archive from the storage service and uploads deploy archive to it.
+The fetcher inside the function pod also pulls the deploy archive for function specialization.
+
+## Optional Components
+
+### Logger
+
+Logger is deployed as DaemonSet to help to forward function logs to a centralized 
+database service for log persistence. Currently, only InfluxDB is supported to store logs.
+
+Following is a diagram describe how log service works:
+1. Logger watches pod changes and creates a symlink to the container log if the pod runs on the same node.
+2. Fluentd reads logs from symlink and pipes them to InfluxDB
+3. `fission function logs ...` retrieve event logs from InfluxDB with optional log filter
+4. Logger removes the symlink if the pod no longer exists.
+
+### Kubewatcher
 
 Kubewatcher watches the Kubernetes API and invokes functions
 associated with watches, sending the watch event to the function.
 
-The controller keeps track of user's requested watches and associated
-functions.  Kubewatcher watches the API based on these requests; when
+The controller keeps track of the user's requested watches and associated

 While a few simple retries are done, there isn't yet a reliable
-message bus between Kubewatcher and the function.  Work for this is

 tracked in issue #64.
 
-Message Queue Trigger

+### Message Queue Trigger
 
 A message queue trigger binds a message queue topic to a function:
-events from that topic cause the function to be invoked with the
+Events from that topic cause the function to be invoked with the
 message as the body of the request. The trigger may also contain a

-Environment Container
----------------------
+### Timer
 
-Environment containers run user-defined functions.  Environment
-containers are language specific. Each environment container must 
-contain an HTTP server and a loader for functions.

+Go server launches `tensorflow_model_server` to load in model during specialization. As long as the Go server receives
+requests from router it creates a reverse proxy that connects to RESTful API endpoint exposed by tensorflow_model_server
+and get response from the upstream server for user.
+
+## Build this image
+
+```
+docker build -t USER/tensorflow-serving . && docker push USER/tensorflow-serving
+```
+
+## Using the image in fission
+
+You can add this customized image to fission with "fission env create":
+
+```
+fission env create --name tensorflow --image USER/tensorflow-serving --version 2
+```
+
+After this, fission functions that have the env parameter set to the
+same environment name as this command will use this environment.

-This code is a starting point for your Google App Engine application in
-Go.
-
-To run the application locally you need the install the [Go Cloud
-SDK](https://cloud.google.com/appengine/docs/go/#Go_tools) and execute the next
-command from the directory containing this file:
-
-    $ goapp serve app.yaml
-
-To deploy the application you have to first create an App Engine project
-and use it as the application file in all the yaml files.
