PSPDFKit Server has been deprecated and replaced by Document Engine. To migrate to Document Engine and unlock advanced document processing capabilities, refer to our migration guide. Learn more about these enhancements on our blog.

This guide will walk you through the steps for deploying PSPDFKit Server to the Microsoft Azure Container Service(opens in a new tab) with Kubernetes(opens in a new tab).

Setting up Azure CLI

To be able to deploy PSPDFKit Server to the Microsoft Azure Container Service(opens in a new tab) with Kubernetes(opens in a new tab), you have to set up the Azure CLI(opens in a new tab) utility to manage your Kubernetes(opens in a new tab) cluster in the command line.

To install Azure CLI(opens in a new tab), follow the installation instructions from the Azure CLI installation guide(opens in a new tab).

After you’ve installed Azure CLI(opens in a new tab), run the following command to log in to Microsoft Azure(opens in a new tab):

az login

This command will print the URL https://microsoft.com/devicelogin(opens in a new tab) and the code for signing in. Open the URL in your browser and enter the code to sign in to your Microsoft Azure(opens in a new tab) account.

Creating a resource group

To create a resource group, run the following:

az group create -l eastus -n pspdfkitresourcegroup

In this example, we created the resource group in the eastus region with the name pspdfkitresourcegroup. An overview of available regions can be found on Microsoft's Azure Regions(opens in a new tab) page.

Creating a Kubernetes cluster

To be able to manage your Kubernetes(opens in a new tab) cluster from the command line, you have to install kubectl(opens in a new tab):

az aks install-cli

To create a Kubernetes(opens in a new tab) cluster with the name pspdfkitAKScluster, run the following:

az aks create -g pspdfkitresourcegroup --name pspdfkitAKScluster --generate-ssh-keys

To connect kubectl(opens in a new tab) with your cluster, execute:

az aks get-credentials -g pspdfkitresourcegroup -n pspdfkitAKScluster

Creating a ConfigMap

ConfigMaps(opens in a new tab) allow you to decouple configuration artifacts from image content. To create the pspdfkit-config ConfigMap(opens in a new tab), run the following command:

kubectl create configmap pspdfkit-config

After the ConfigMap(opens in a new tab) is created, you can edit it with the following:

kubectl edit configmap pspdfkit-config

This should open the created ConfigMap(opens in a new tab) in your editor. Edit the file to match the following file and replace activation_key with your activation key:

# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving,
# this file will be reopened with the relevant failures.

  pguser: pspdfkit
  secret_key_base: secret-key-base
kind: ConfigMap

Don’t change anything that comes after the kind: ConfigMap line, because that part is autogenerated.

Creating an Azure Disk Volume

To create the Azure Disk Volume(opens in a new tab) where the database saves the data, run:

az group list --output table

This will print a list of resource groups. Copy the name of the resource group that starts with MC — for example, MC_pspdfkitresourcegroup_pspdfkitAKScluster_eastus — and insert it into the following command after --resource-group:

az disk create \
  --resource-group MC_pspdfkitresourcegroup_pspdfkitAKScluster_eastus \
  --name postgres-disk\
  --size-gb 50 \
  --query id --output tsv

This will print the disk ID of the created disk. For example:

/subscriptions/12345abc-def1-2345-6789-abcdef123456/resourceGroups/MC_pspdfkitresourcegroup_pspdfkitAKScluster_eastus/providers/Microsoft.Compute/disks/postgres-disk

Creating Services and Deployments

Kubernetes Services(opens in a new tab) and Deployments(opens in a new tab) can be configured in a file. To run PSPDFKit Server, you have to define a Service and a Deployment for the database and a Service and a Deployment for PSPDFKit Server. First, create the file that configures the database Service and Deployment. To do this, create the pspdfkitdb.yml file in the current directory:

apiVersion: v1
kind: Service
metadata:
  name: pspdfkitdb
spec:
  ports:
    - port: 5432
  selector:
    app: pspdfkitdb
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: pspdfkitdb
spec:
  selector:
    matchLabels:
      app: pspdfkitdb
  template:
    metadata:
      labels:
        app: pspdfkitdb
    spec:
      containers:
        - image: "postgres:15"
          name: pspdfkitdb
          env:
            - name: POSTGRES_USER
              valueFrom:
                configMapKeyRef:
                  name: pspdfkit-config
                  key: pguser
            - name: POSTGRES_PASSWORD
              valueFrom:
                configMapKeyRef:
                  name: pspdfkit-config
                  key: pgpassword
            - name: PGDATA
              valueFrom:
                configMapKeyRef:
                  name: pspdfkit-config
                  key: pgdata
          ports:
            - containerPort: 5432
              name: pspdfkitdb
          volumeMounts:
            - name: postgres-storage
              mountPath: /var/lib/postgresql/data
      volumes:
        - name: postgres-storage
          azureDisk:
            kind: Managed
            diskName: postgres-disk
            diskURI: /subscriptions/12345abc-def1-2345-6789-abcdef123456/resourceGroups/MC_pspdfkitresourcegroup_pspdfkitAKScluster_eastus/providers/Microsoft.Compute/disks/postgres-disk

Make sure to replace diskURI in the last line with the disk ID you got from the command before.

After you’ve created the configuration file for the database, create the configuration for PSPDFKit Server (pspdfkit.yml) and ensure that the pspdfkit/pspdfkit image tag corresponds to the latest PSPDFKit Server version:

apiVersion: v1
kind: Service
metadata:
  name: pspdfkit

    - protocol: TCP
      port: 5000

      containers:
        - image: "pspdfkit/pspdfkit:1.4.1"
          name: pspdfkit

            - name: PGUSER
              valueFrom:
                configMapKeyRef:
                  name: pspdfkit-config

                  key: jwt_public_key
            - name: DASHBOARD_USERNAME
              valueFrom:
                configMapKeyRef:
                  name: pspdfkit-config
                  key: dashboard_username
            - name: DASHBOARD_PASSWORD
              valueFrom:
                configMapKeyRef:
                  name: pspdfkit-config
                  key: dashboard_password
          ports:
            - containerPort: 5000
              name: pspdfkit

To create all Services and Deployments needed to run PSPDFKit Server, execute:

kubectl create -f ./pspdfkitdb.yml

kubectl create -f ./pspdfkit.yml

Viewing the dashboard

To be able to access the server, you have to get the external IP address that was assigned to the server. Run the following command to view all the Services in your cluster, along with their assigned external IP addresses:

kubectl get services

This will show something like the following:

NAME         TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)          AGE
kubernetes   ClusterIP      10.15.240.1     <none>           443/TCP          54m
pspdfkit     LoadBalancer   10.15.247.197   12.345.678.910   5000:32393/TCP   1m
pspdfkitdb   ClusterIP      10.15.244.127   <none>           5432/TCP         4m

Copy the EXTERNAL-IP address from the pspdfkit column and access the dashboard with the port 5000 and the /dashboard path in your web browser. In this example, you would access the dashboard with http://12.345.678.910:5000/dashboard.

Limitations

Be aware that this is just an example setup, and we recommend looking deeper into the Microsoft Azure Container Service(opens in a new tab) for a production-ready setup.
