# Validating admission webhook
|
||||
|
||||
## Building Docker image
|
||||
|
||||
From the root directory of Multus execute:
|
||||
```
|
||||
cd webhook
|
||||
./build
|
||||
```
|
||||
|
||||
## Deploying webhook application
|
||||
|
||||
Change working directory. From the root directory of Multus execute:
|
||||
```
|
||||
cd deployment/webhook
|
||||
```
|
||||
|
||||
Create key and certificate pair and patch configuration-template.yaml file with base64-encoded certificate file. Run:
|
||||
```
|
||||
./certs.sh
|
||||
```
|
||||
*Note: Verify that Kubernetes controller manager has --cluster-signing-cert-file and --cluster-signing-key-file parameters set to paths to your CA keypair,
|
||||
to make sure that Certificates API is enabled in order to generate certificate signed by cluster CA.
|
||||
Script generates private key and certificate signing request, which is then pushed to the Kubernetes API server.
|
||||
Then script approves that CSR and API server issues the certificate. Certificate is obtained from the API server and used to create a secret.
|
||||
Script also patches `configuration-template.yaml` file with base64-encoded certificate and creates `configuration.yaml` file containing
|
||||
Validating Webhook Configuration specification, which is deployed in one of the next steps.
|
||||
More details about TLS certificates management in a cluster available [here](https://kubernetes.io/docs/tasks/tls/managing-tls-in-a-cluster/).*
|
||||
|
||||
Create service:
|
||||
```
|
||||
kubectl create -f service.yaml
|
||||
```
|
||||
|
||||
Run deployment:
|
||||
```
|
||||
kubectl create -f deployment.yaml
|
||||
```
|
||||
|
||||
Create Validating Webhook Configuration:
|
||||
```
|
||||
kubectl create -f configuration.yaml
|
||||
```
|
||||
|
||||
## Verifying installation
|
||||
|
||||
Try to create invalid Network Attachment Definition resource:
|
||||
```
|
||||
cat <<EOF | kubectl create -f -
|
||||

|
||||

|
||||

|
||||

|
||||
config: '{
|
||||
"invalid": "config"
|

}'
|
||||
EOF
|
||||
```
|
||||
Webhook should deny the request:
|
||||
```
|

Error from server: error when creating "STDIN": admission webhook "multus-webhook.k8s.cni.cncf.io" denied the request: Invalid network config spec
|
||||

|
||||

||||

||||
```

|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
Webhook server prints a lot of debug messages that could help to find the root cause of an issue.
|
||||
To display logs run:
|
||||
```
|
||||
kubectl logs -l app=multus-webhook

the (x, y, z int) shorthand is not allowed.

/*
|
||||
This program reads a file containing function prototypes
|
||||
(like syscall_aix.go) and generates system call bodies.
|
||||
The prototypes are marked by lines beginning with "//sys"
|
||||
and read like func declarations if //sys is replaced by func, but:
|
||||
* The parameter lists must give a name for each argument.
|
||||
This includes return parameters.
|
||||
* The parameter lists must give a type for each argument:
|
||||
the (x, y, z int) shorthand is not allowed.
|
||||
* If the return parameter is an error number, it must be named err.
|
||||
* If go func name needs to be different than its libc name,
|
||||
* or the function is not in libc, name could be specified
|
||||
* at the end, after "=" sign, like
|
||||
//sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
|
||||
|
||||
|
||||
This program will generate three files and handle both gc and gccgo implementation:
|
||||
- zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
|
||||
- zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
|
||||
- zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
|
||||
|
||||
The generated code looks like this
|
||||
|
||||
zsyscall_aix_ppc64.go
|
||||
func asyscall(...) (n int, err error) {
|
||||
// Pointer Creation
|

// Type Conversion
|

// Error Handler
|
||||
return
|
||||
}
|
||||
|
||||
zsyscall_aix_ppc64_gc.go
|
||||
//go:cgo_import_dynamic libc_asyscall asyscall "libc.a/shr_64.o"
|
||||
//go:linkname libc_asyscall libc_asyscall
|

|

func callasyscall(...) (r1 uintptr, e1 Errno) {

r1, _, e1 = syscall6(uintptr(unsafe.Pointer(&libc_asyscall)), "nb_args", ... )
