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.
```
Tests for updates to a function of new deployment executor type. Tests check for changes in the environment, scale, secrets etc. Also checks conversion of function executor type from new deployment to pool manager and vice versa
The Deployment definition for executor, controller, router contains readines/liveness probes. The port definition for those probes should be numbers, instead of string, i.e. port: "8888" should be port 8888.
Environment Specs so far had only an image URL to specify a container image.
This was fine for public images but fell short in a few of cases:
(a) Using private image registries
(b) Specifying environment variables (this is needed for workflows helm install)
(c) Setting a SecurityContext for the container
This change adds the Container object to both build and runtime Environments.
Compatibility is preserved -- the existing ImageURL field is still used. See the comments in types.go for the overriding rules in the case that both Container and ImageURL are specified.
Newdeploy manager now checks the existence of function service cache by function UID before trying to create a new deployment. And return the cached fsvc directly if the cache exists.
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.
The fetcher needs a relatively smaller set of resources and does not have to be same as the function container/defaults. This change adds defaults for fetcher containers in function pods.
