Mounting the Font Package for LibreOffice

I. Create a Font Package Directory​

  1. On the server, create a font package directory and upload the font package.

    mkdir -p /data/mingdao/script/volume/ldoc/font-packages
    • Store the font package in the /data/mingdao/script/volume/ldoc/font-packages directory.

II. Configuration Steps​

Configuration Based on a HAP Standalone Environment​

  1. Use vim /data/mingdao/script/docker-compose.yaml to add the mount - ./volume/ldoc/font-packages/:/usr/share/fonts/font-packages/

     services:
       app:
         image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-community:6.5.2
         environment:
           ENV_DOCPREVIRE_EXT_ENDPOINTS: "ldoc:8000"
     
       ldoc:
         image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-ldoc:2.0.2
         volumes: # Added
           - ./volume/ldoc/font-packages/:/usr/share/fonts/font-packages/ # Added

  2. Then restart the hap service to apply changes

    Execute the restart command in the manager directory

     bash ./service.sh restartall

Deploying ldoc Service Independently via Docker​

  1. Use vim ldoc.yaml to add the mount - /data/mingdao/script/volume/ldoc/font-packages/:/usr/share/fonts/font-packages/

    version: '3'

    services:
      ldoc:
        image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-ldoc:2.0.2
        ports:
          - 8881:8000
        volumes: # Added
          - /data/mingdao/script/volume/ldoc/font-packages/:/usr/share/fonts/font-packages/ # Added

  2. Then restart the LibreOffice service to apply changes

    Execute the restart command in the directory containing ldoc.yaml

     # 1. Stop ldoc
     docker stack rm ldoc 

     # 2. Check ldoc
     docker ps -a | grep ldoc

     # 3. Once no ldoc container is found in step 2, start ldoc
     docker stack deploy -c ldoc.yaml ldoc

Deploying ldoc Service with Kubernetes​

Note: The step of Creating Font Package Directory must be performed on each node of the microservice and the font package uploaded.

  1. Modify the mount configuration of the deployment for ldoc, using the hostpath method to mount.

    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: ldoc
      namespace: default
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: ldoc
      template:
        metadata:
          labels:
            app: ldoc
        spec:
          containers:
          - name: ldoc
            image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-ldoc:2.0.2
            resources:
              limits:
                cpu: "4"
                memory: 4096Mi
              requests:
                cpu: "0.01"
                memory: 64Mi
            readinessProbe:
              tcpSocket:
                port: 8000
              initialDelaySeconds: 10
              periodSeconds: 10
            livenessProbe:
              tcpSocket:
                port: 8000
              initialDelaySeconds: 180
              periodSeconds: 10
            volumeMounts: # Added
              - name: font-packages # Added
                mountPath: /usr/share/fonts/font-packages/ # Added
          volumes: # Added
            - name: font-packages # Added
              hostPath: # Added
                path: /data/mingdao/script/volume/ldoc/font-packages/ # Added

    ---

    apiVersion: v1
    kind: Service
    metadata:
      name: ldoc
      namespace: default
    spec:
      selector:
        app: ldoc
      ports:
        - name: internal
          port: 8001
          targetPort: 8000

  2. Then restart the LibreOffice service to apply changes

    Execute the restart command in the directory containing service.yaml

     kubectl apply -f service.yaml

     # Check once the pod is started
     kubectl get pods | grep ldoc

     # If ldoc does not restart, you can manually perform a rolling restart
     kubectl rollout restart deploy ldoc
