Deployment

Pre-requisites

Install openssl on K8s control-plane
Ensure a docker registry is running locally or remotely.

Note

For single node microk8s deployment, a registry can be brought up by using microk8s add-ons. More details present in Microk8s documentation. This is not mandatory, if a remote registry already exists, the same can be used as well for single-node

Note

For multi-node kubeadm deployment, a docker registry needs to be setup by the user

Push all container images to docker registry. Example below

# Without TLS enabled
skopeo copy oci-archive:<oci-image-tar-name> docker://<registry-ip/hostname>:<registry-port>/<image-name>:<image-tag> --dest-tls-verify=false

# With TLS enabled
skopeo copy oci-archive:<oci-image-tar-name> docker://<registry-ip/hostname>:<registry-port>/image-name>:<image-tag>

Note

In case of microk8s deployment, when docker registry is enabled locally, the OCI container images need to be copied to the node where registry is enabled and then the above example command can be run. The same would not be required when registry is remotely installed

On each worker node with TXT/BTG enabled and registered to K8s control-plane, the following pre-req needs to be done on RHEL-8.3/Ubuntu-18.04 systems
Foundational Security
- Tboot-1.10.1 or later to be installed for non SUEFI servers. Tboot installation Details
- Only for Ubuntu-18.04, run the following commands
```
$ modprobe msr
```
Workload Security
- Container Confidentiality with CRIO runtime
- Tboot-1.10.1 or later to be installed for non SUEFI servers. Tboot installation Details
- Copy container-runtime directory to each of the physical servers
- Run the install-prereqs-crio.sh script on the physical servers from container-runtime
Note
container-runtime scripts need to be run on TXT/BTG/SUEFI enabled services
- Reboot the server
- Only for Ubuntu-18.04, run the following command
```
$ modprobe msr
```

Deploy

Single-Node

Pre-requisites

Setup

microk8s being the default supported single node K8s distribution, users would need to install microk8s on a Physical server
Copy all manifests and OCI container images as required to KK8s control-plane
Ensure docker registry is running locally or remotely
The K8s cluster admin should configure the existing bare metal worker nodes or register fresh bare metal worker nodes with labels. For example, a label like node.type: TXT-ENABLED or node.type: SUEFI-ENABLED respectively for TXT/SUEFI enabled servers can be used by the cluster admin to distinguish the baremetal worker node and the same label can be used in ISECL Agent pod configuration to schedule on all worker nodes marked with the label. The same label is being used as default in the K8s manifests. This can be edited in k8s/manifests/ta/daemonset.yml , k8s/manifests/wla/daemonset.yml

Refer Section in appendix for Feature Detection - node.type: TXT-ENABLED should be labeled for nodes installed with tboot, where event logs will be collected from tboot measurements. - node.type: SUEFI-ENABLED should be labeled for nodes with SUEFI enabled, where event logs will be efi logs.

#Label node for TXT
kubectl label node <node-name> node.type=TXT-ENABLED

#Label node for SUEFI
kubectl label node <node-name> node.type=SUEFI-ENABLED

In case of microk8s cluster, the --allow-privileged=true flag needs to be added to the kube-apiserver under /var/snap/microk8s/current/args/kube-apiserver and restart kube-apiserver with systemctl restart snap.microk8s.daemon-apiserver to allow running of privileged containers like TRUST-AGENT and WORKLOAD-AGENT
Ensure a backend KMIP-2.0 compliant server like pykmip is up and running.

Manifests

Update all the K8s manifests with the image names to be pulled from the registry
The tolerations and node-affinity in case of isecl-scheduler and isecl-controller needs to be updated in the respective manifests under the manifests/k8s-extensions-controller and manifests/k8s-extensions-scheduler directories to microk8s.io/cluster based on k8s distributions of kubeadm and microk8s respectively

Deploy steps

The bootstrap script would facilitate the deployment of all FS,WS components at a use case level. Sample one given below.

#        usecase    Can be one of foundational-security, workload-security, isecl-#orchestration-k8s, csp, enterprise

./isecl-bootstrap.sh up <all/usecase of choice>

Note

An error to create asymmetric key would mean the following line, RANDFILE = $ENV::HOME/.rnd needs to be commented under /etc/ssl/openssl.cnf

Update the IHUB_PUB_KEY_PATH in isecl-k8s.env to /etc/ihub/ihub_public_key.pem
Bring up isecl-scheduler

./isecl-bootstrap.sh up isecl-scheduler

Copy scheduler-policy.json

mkdir -p /opt/isecl-k8s-extensions
cp manifests/k8s-extensions-scheduler/config/scheduler-policy.json /opt/isecl-k8s-extensions/

Edit kube-scheduler and restart kubelet

#Edit the kube-scheduler

#Add the below line
--policy-config-file=/opt/isecl-k8s-extensions/scheduler-policy.json

#Restart kubelet
systemctl restart snap.microk8s.daemon-kubelet.service

Multi-Node

Pre-requisites

Setup

kubeadm being the default supported multi-node K8s distribution, users would need to install a kubeadm K8s control-plane node setup
Copy all manifests and OCI container images as required to K8s control-plane
Ensure images are pushed to registry locally or remotely
The K8s cluster admin should configure the existing bare metal worker nodes or register fresh bare metal worker nodes with labels. For example, a label like node.type: TXT-ENABLED or node.type: SUEFI-ENABLED respectively for TXT/SUEFI enabled servers can be used by the cluster admin to distinguish the baremetal worker node and the same label can be used in ISECL Agent pod configuration to schedule on all worker nodes marked with the label. The same label is being used as default in the K8s manifests. This can be edited in k8s/manifests/ta/daemonset.yml , k8s/manifests/wla/daemonset.yml

kubectl label node <node-name> node.type=SUEFI-ENABLED

NFS storage class is used in kubernetes environment for data persistence and supported in ISecL FS/WS usecases. User needs to setup NFS server and create directory structure along with granting permission for a given user id. From security point of view, its been recommended to create a separate user id and grant the permission for all isecl directories for this user id. Below are some samples for reference
Snapshot showing directory structure for which user needs to create on NFS volumes manually or using custom scripts.

NFS Directory Structure FS/WS Usecase

Snapshot showing ownership and permissions for directories for which user needs to manually grant the ownership.

NFS Directory Permissions FS/WS Usecase

Snapshot for configuring PV and PVC , user need to provide the NFS server IP or hostname and paths for each of the service directories. Sample manifest for creating config-pv for cms service

---
apiVersion: v1
kind: PersistentVolume
metadata:
    name: cms-config-pv
spec:
    capacity:
    storage: 128Mi
    volumeMode: Filesystem
    accessModes:
    - ReadWriteMany
    persistentVolumeReclaimPolicy: Retain
    storageClassName: nfs
    nfs:
    path: /<NFS-vol-base-path>/isecl/cms/config
    server: <NFS Server IP/Hostname>

Sample manifest for creating config-pvc for cms service

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: cms-config-pvc
  namespace: isecl
spec:
  storageClassName: nfs
  accessModes:
  - ReadWriteMany
  resources:
  requests:
      storage: 128Mi

Note

The user id specified in security context in deployment.yml for a given service and owner of the service related directories in NFS must be same

Ensure a backend KMIP-2.0 compliant server like pykmip is up and running.

Manifests

Update all the K8s manifests with the image names to be pulled from the registry
The tolerations and node-affinity in case of isecl-scheduler and isecl-controller needs to be updated in the respective manifests under the manifests/k8s-extensions-controller and manifests/k8s-extensions-scheduler directories to node-role.kubernetes.io/master
All NFS PV yaml files needs to be updated with the path: /<NFS-vol-path> and server: <NFS Server IP/Hostname> under each service manifest file for config, logs , db-data

Deploy steps

Update `isecl-k8s.env` file
