Kubernetes Configuration
- MetaDefender ICAP Server has already deploy to K8S environment by MetaDefender ICAP Server helm (refer to: Using your existing Kubernetes (K8S) cluster)
Option 1: using NGINX Ingress
Setup Metallb:
- Clone metallb
- update helm-bitnami/bitnami/metallb/values.yaml
- install helm chart
xxxxxxxxxxhelm install metallb .- make sure metallb is running
xxxxxxxxxxkubectl get pods | grep metallbxxxxxxxxxxdefault metallb-controller-5ffbcf4b7f-pnnj7 1/1 Running 0 10mdefault metallb-speaker-25j59Setup NGINX ingress:
- get ingress-nginx
xxxxxxxxxxgit clone https://github.com/kubernetes/ingress-nginx.git- append below to values.yml
xxxxxxxxxx# Need to update it because default Nginx Ingress doesn't support TCP protocoltcp: 1344: "default/md-icapsrv:1344" #Exposing TCP service, <default> is the namespace install md-icapsrv 11344: "default/md-icapsrv:11344"- Helm install Nginx-ingress
xxxxxxxxxx$ helm install ingress-nginx .- Create file ingress.yml as below:
the hostname can be changed and this is used as the domain to connect to MD ICAP Server
E.g:
host: md-icapsrv-ui.example.com
xxxxxxxxxxapiVersion: networking.k8s.io/v1kind: Ingressmetadata: name: icap-ingress namespace: defaultspec: ingressClassName: nginx rules: - host: md-icapsrv-ui.example.com http: paths: - backend: service: name: md-icapsrv port: number: 8048 path: / pathType: Prefix - backend: service: name: md-icapsrv port: number: 8048 path: /* pathType: Prefix - host: md-icapsrv.example.com http: paths: - backend: service: name: md-icapsrv port: number: 1344 path: / pathType: Prefix - backend: service: name: md-icapsrv port: number: 1344 path: /* pathType: Prefix - host: md-icapsrv-tls.example.com http: paths: - backend: service: name: md-icapsrv port: number: 11344 path: / pathType: Prefix - backend: service: name: md-icapsrv port: number: 11344 path: /* pathType: Prefix- Create ingress resources on Kubernetes
xxxxxxxxxxkubectl apply -f ./ingress.yml- Verify Metallb assign IP address external to Nginx-ingress
xxxxxxxxxxkubectl get ing -ANAMESPACE NAME CLASS HOSTS ADDRESS PORTS AGEdefault icap-ingress nginx md-icapsrv-ui.opswat.local,md-icapsrv.opswat.local,md-icapsrv-tls.opswat.local 10.40.162.150 80 18mThe UI to connect to MD ICAP Server
- ICAP: md-icapsrv.opswat.local:1344/OMSScanReq-AV
- ICAPS: md-icapsrv-tls.opswat.local:11344/OMSScanResp-AV
E.g: for Squid integration
- ICAP:
icap_service metascan_req reqmod_precache bypass=0 icap://1md-icapsrv.opswat.local:1344/OMSScanReq-AV
- ICAPS:
icap_service metascan_resp respmod_precache bypass=0 icap://md-icapsrv.opswat.local:11344/OMSScanResp-AV
Option 2: Using NodePort
- Update field service_type from ClusterIP to NodePort in values.yaml of ICAP helm and save to file update_nodeport_values.yml
- Update config
xxxxxxxxxxhelm install md-icapsrv -f update_nodeport_values.yml .- make sure pod MetaDefender ICAP Server is running
xxxxxxxxxxkubectl get pods -AFor example: this case md-icapsrv-5df4bb8547-czp88 is running
- Get service port with CLI
xxxxxxxxxxkubectl get svc -A | grep md-icapsrvFor example: the service port mapping ressult:
- 8048:31988/TCP
- 1344:32233/TCP
- 11344:32568/TCP
- Check the MetaDefender ICAP Server is running on the worker node
xxxxxxxxxxkubectl get pods -A
- Describe pod md-icapsrv-5df4bb8547-czp88 to get the IP address
xxxxxxxxxxkubectl describe pod md-icapsrv-5df4bb8547-czp88
- ICAP Client will connect to MetaDefender ICAP Server via below IP and Port
xxxxxxxxxxICAP: 10.40.162.102:32233ICAPS: 10.40.162.102:32568 E.g: for Squid integrationicap_service metascan_req reqmod_precache bypass=0 icap://10.40.162.102:32233/OMSScanReq-AVicap_service metascan_resp respmod_precache bypass=0 icap://10.40.162.102:32568/OMSScanResp-AV
