ONLYOFFICE Docs for Kubernetes

Contents

Introduction

  • You must have a Kubernetes cluster installed. Please, checkout the reference to set up Kubernetes.
  • You should also have a local configured copy of kubectl. See this guide how to install and configure kubectl.
  • You should install Helm v3.15+. Please follow the instruction here to install it.

Deploy prerequisites

1. Add Helm repositories

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm repo add nfs-server-provisioner https://kubernetes-sigs.github.io/nfs-ganesha-server-and-external-provisioner
$ helm repo add onlyoffice https://download.onlyoffice.com/charts/stable
$ helm repo update

2. Install Persistent Storage

Install NFS Server Provisioner

Note: Pesistent storage will be used for forgotten and error files

Note: When installing NFS Server Provisioner, Storage Classes - NFS is created.

$ helm install nfs-server nfs-server-provisioner/nfs-server-provisioner \
  --set persistence.enabled=true \
  --set persistence.storageClass=PERSISTENT_STORAGE_CLASS \
  --set persistence.size=PERSISTENT_SIZE

  • PERSISTENT_STORAGE_CLASS is a Persistent Storage Class available in your Kubernetes cluster.

    Persistent Storage Classes for different providers:

    • Amazon EKS: gp2
    • Digital Ocean: do-block-storage
    • IBM Cloud: Default ibmc-file-bronze. More storage classes
    • Yandex Cloud: yc-network-hdd or yc-network-ssd. More details
    • minikube: standard
    • k3s: local-path

  • PERSISTENT_SIZE is the total size of all Persistent Storages for the nfs Persistent Storage Class. You can express the size as a plain integer with one of these suffixes: T, G, M, Ti, Gi, Mi. For example: 9Gi.

See more details about installing NFS Server Provisioner via Helm here.

Configure a Persistent Volume Claim

The PersistentVolume type to be used for PVC placement must support Access Mode ReadWriteMany. Also, PersistentVolume must have as the owner the user from whom the ONLYOFFICE Docs will be started. By default it is ds (101:101).

Note: If you want to enable WOPI, please set the parameter wopi.enabled=true. In this case Persistent Storage must be connected to the cluster nodes with the disabled caching attributes for the mounted directory for the clients. For NFS Server Provisioner it can be achieved by adding noac option to the parameter storageClass.mountOptions. Please find more information here.

3. Deploy Redis

To install Redis to your cluster, run the following command:

$ helm install redis bitnami/redis \
  --set architecture=standalone \
  --set master.persistence.storageClass=PERSISTENT_STORAGE_CLASS \
  --set master.persistence.size=8Gi \
  --set metrics.enabled=false

Note: Set the metrics.enabled=true to enable exposing Redis metrics to be gathered by Prometheus.

See more details about installing Redis via Helm here.

4. Deploy StatsD exporter

This step is optional. You can skip step #4 entirely if you don't want to run StatsD exporter

4.1 Add Helm repositories

$ helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
$ helm repo add kube-state-metrics https://kubernetes.github.io/kube-state-metrics
$ helm repo update

4.2 Installing Prometheus

To install Prometheus to your cluster, run the following command:

$ helm install prometheus -f https://raw.githubusercontent.com/ONLYOFFICE/Kubernetes-Docs/master/sources/extraScrapeConfigs.yaml prometheus-community/prometheus \
  --set server.global.scrape_interval=1m

To change the scrape interval, specify the server.global.scrape_interval parameter.

See more details about installing Prometheus via Helm here.

4.3 Installing StatsD exporter

To install StatsD exporter to your cluster, run the following command:

$ helm install statsd-exporter prometheus-community/prometheus-statsd-exporter \
  --set statsd.udpPort=8125 \
  --set statsd.tcpPort=8126 \
  --set statsd.eventFlushInterval=30000ms

See more details about installing Prometheus StatsD exporter via Helm here.

To allow the StatsD metrics in ONLYOFFICE Docs, follow step 5.2

5. Make changes to Node-config configuration files

This step is optional. You can skip step #5 entirely if you don't need to make changes to the configuration files

5.1 Create a ConfigMap containing a json file

In order to create a ConfigMap from a file that contains the local-production-linux.json structure, you need to run the following command:

$ kubectl create configmap custom-local-config \
  --from-file=./local-production-linux.json

Note: Any name except local-config can be used instead of custom-local-config.

5.2 Specify parameters when installing ONLYOFFICE Docs

When installing ONLYOFFICE Docs, specify the extraConf.configMap=custom-local-config and extraConf.filename=local-production-linux.json parameters

Note: If you need to add a configuration file after the ONLYOFFICE Docs is already installed, you need to execute step 5.1 and then run the helm upgrade documentserver onlyoffice/docs-shards --set extraConf.configMap=custom-local-config --set extraConf.filename=local-production-linux.json command or helm upgrade documentserver -f ./values.yaml onlyoffice/docs-shards if the parameters are specified in the values.yaml file.

6. Add custom Fonts

This step is optional. You can skip step #6 entirely if you don't need to add your fonts

In order to add fonts to images, you need to rebuild the images. Refer to the relevant steps in this manual. Then specify your images when installing the ONLYOFFICE Docs.

7. Add Plugins

This step is optional. You can skip step #7 entirely if you don't need to add plugins

In order to add plugins to images, you need to rebuild the images. Refer to the relevant steps in this manual. Then specify your images when installing the ONLYOFFICE Docs.

8. Change interface themes

This step is optional. You can skip step #8 entirely if you don't need to change the interface themes

8.1 Create a ConfigMap containing a json file

To create a ConfigMap with a json file that contains the interface themes, you need to run the following command:

$ kubectl create configmap custom-themes \
  --from-file=./custom-themes.json

Note: Instead of custom-themes and custom-themes.json you can use any other names.

8.2 Specify parameters when installing ONLYOFFICE Docs

When installing ONLYOFFICE Docs, specify the extraThemes.configMap=custom-themes and extraThemes.filename=custom-themes.json parameters.

Note: If you need to add interface themes after the ONLYOFFICE Docs is already installed, you need to execute step 5.1 and then run the helm upgrade documentserver onlyoffice/docs-shards --set extraThemes.configMap=custom-themes --set extraThemes.filename=custom-themes.json command or helm upgrade documentserver -f ./values.yaml onlyoffice/docs-shards if the parameters are specified in the values.yaml file.

Deploy ONLYOFFICE Docs

1. Deploy the ONLYOFFICE Docs license

1.1. Create secret

If you have a valid ONLYOFFICE Docs license, create a secret license from the file:

$ kubectl create secret generic license --from-file=path/to/license.lic

Note: The source license file name should be 'license.lic' because this name would be used as a field in the created secret.

1.2. Specify parameters when installing ONLYOFFICE Docs

When installing ONLYOFFICE Docs, specify the license.existingSecret=license parameter.

$ helm install documentserver onlyoffice/docs-shards --set license.existingSecret=license

Note: If you need to add license after the ONLYOFFICE Docs is already installed, you need to execute step 1.1 and then run the helm upgrade documentserver onlyoffice/docs-shards --set license.existingSecret=license command or helm upgrade documentserver -f ./values.yaml onlyoffice/docs-shards if the parameters are specified in the values.yaml file.

2. Deploy ONLYOFFICE Docs

To deploy ONLYOFFICE Docs with the release name documentserver:

$ helm install documentserver onlyoffice/docs-shards

The command deploys ONLYOFFICE Docs on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

3. Uninstall ONLYOFFICE Docs

To uninstall/delete the documentserver deployment:

$ helm delete documentserver

The helm delete command removes all the Kubernetes components associated with the chart and deletes the release.

  • *Note: The prefix -de is specified in the value of the image repository, which means solution type. Possible options:

    • Nothing is specified. For the open-source community version
    • -de. For commercial Developer Edition
    • -ee. For commercial Enterprise Edition

    If you use the community version, there may be problems with co-editing documents.

    The default value of this parameter refers to the ONLYOFFICE Document Server Developer Edition. To learn more about this edition and compare it with other editions, please see the comparison table on this page.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install documentserver onlyoffice/docs-shards --set ingress.enabled=true,ingress.ssl.enabled=true,ingress.host=example.com

This command gives expose ONLYOFFICE Docs via HTTPS.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install documentserver -f values.yaml onlyoffice/docs-shards

Tip: You can use the default values.yaml

5. Configuration and installation details

5.1 Example deployment (optional)

To deploy the example, set the example.enabled parameter to true:

$ helm install documentserver onlyoffice/docs-shards --set example.enabled=true

5.2 Metrics deployment (optional)

To deploy metrics, set metrics.enabled to true:

$ helm install documentserver onlyoffice/docs-shards --set metrics.enabled=true

If you want to use Grafana to visualize metrics, set grafana.enabled to true. If you want to use Nginx Ingress to access Grafana, set grafana.ingress.enabled to true:

$ helm install documentserver onlyoffice/docs-shards --set grafana.enabled=true --set grafana.ingress.enabled=true

5.3 Expose ONLYOFFICE Docs

5.3.1 Expose ONLYOFFICE Docs via Service (HTTP Only)

You should skip step#5.3.1 if you are going to expose ONLYOFFICE Docs via HTTPS

This type of exposure has the least overheads of performance, it creates a loadbalancer to get access to ONLYOFFICE Docs. Use this type of exposure if you use external TLS termination, and don't have another WEB application in the k8s cluster.

To expose ONLYOFFICE Docs via service, set the customBalancer.service.type parameter to LoadBalancer:

$ helm install documentserver onlyoffice/docs-shards --set customBalancer.service.type=LoadBalancer,customBalancer.service.port=80

Run the following command to get the documentserver service IP:

$ kubectl get service documentserver -o jsonpath="{.status.loadBalancer.ingress[*].ip}"

After that, ONLYOFFICE Docs will be available at http://DOCUMENTSERVER-SERVICE-IP/.

If the service IP is empty, try getting the documentserver service hostname:

$ kubectl get service documentserver -o jsonpath="{.status.loadBalancer.ingress[*].hostname}"

In this case, ONLYOFFICE Docs will be available at http://DOCUMENTSERVER-SERVICE-HOSTNAME/.

5.3.2 Expose ONLYOFFICE Docs via Ingress

5.3.2.1 Installing the Kubernetes Nginx Ingress Controller

To install the Nginx Ingress Controller to your cluster, run the following command:

$ helm install nginx-ingress ingress-nginx/ingress-nginx --set controller.publishService.enabled=true,controller.replicaCount=2

Note: To install Nginx Ingress with the same parameters and to enable exposing ingress-nginx metrics to be gathered by Prometheus, run the following command:

$ helm install nginx-ingress -f https://raw.githubusercontent.com/ONLYOFFICE/Kubernetes-Docs-Shards/master/sources/ingress_values.yaml ingress-nginx/ingress-nginx

See more detail about installing Nginx Ingress via Helm here.

5.3.2.2 Expose ONLYOFFICE Docs Shards via HTTP

You should skip step5.3.2.2 if you are going to expose ONLYOFFICE Docs via HTTPS

This type of exposure has more overheads of performance compared with exposure via service, it also creates a loadbalancer to get access to ONLYOFFICE Docs. Use this type if you use external TLS termination and when you have several WEB applications in the k8s cluster. You can use the one set of ingress instances and the one loadbalancer for those. It can optimize the entry point performance and reduce your cluster payments, cause providers can charge a fee for each loadbalancer.

To expose ONLYOFFICE Docs via ingress HTTP, set the ingress.enabled parameter to true:

$ helm install documentserver onlyoffice/docs-shards --set ingress.enabled=true

Run the following command to get the documentserver ingress IP:

$ kubectl get ingress documentserver -o jsonpath="{.status.loadBalancer.ingress[*].ip}"

After that, ONLYOFFICE Docs Shards will be available at http://DOCUMENTSERVER-INGRESS-IP/.

If the ingress IP is empty, try getting the documentserver ingress hostname:

$ kubectl get ingress documentserver -o jsonpath="{.status.loadBalancer.ingress[*].hostname}"

In this case, ONLYOFFICE Docs will be available at http://DOCUMENTSERVER-INGRESS-HOSTNAME/.

5.3.2.3 Expose ONLYOFFICE Docs via HTTPS

This type of exposure allows you to enable internal TLS termination for ONLYOFFICE Docs.

Create the tls secret with an ssl certificate inside.

Put the ssl certificate and the private key into the tls.crt and tls.key files and then run:

$ kubectl create secret generic tls \
  --from-file=./tls.crt \
  --from-file=./tls.key
$ helm install documentserver onlyoffice/docs-shards --set ingress.enabled=true,ingress.ssl.enabled=true,ingress.host=example.com

Run the following command to get the documentserver ingress IP:

$ kubectl get ingress documentserver -o jsonpath="{.status.loadBalancer.ingress[*].ip}"

If the ingress IP is empty, try getting the documentserver ingress hostname:

$ kubectl get ingress documentserver -o jsonpath="{.status.loadBalancer.ingress[*].hostname}"

Associate the documentserver ingress IP or hostname with your domain name through your DNS provider.

After that, ONLYOFFICE Docs Shards will be available at https://your-domain-name/.

6. Scale ONLYOFFICE Docs (optional)

This step is optional. You can skip step 6 entirely if you want to use default deployment settings.

6.1 Horizontal Pod Autoscaling

You can enable Autoscaling so that the number of replicas of documentserver deployment is calculated automatically based on the values and type of metrics.

For resource metrics, API metrics.k8s.io must be registered, which is generally provided by metrics-server. It can be launched as a cluster add-on.

To use the target utilization value (target.type==Utilization), it is necessary that the values for resources.requests are specified in the deployment.

For more information about Horizontal Pod Autoscaling, see here.

To enable HPA for the documentserver deployment, specify the documentserver.autoscaling.enabled=true parameter. In this case, the documentserver.replicas parameter is ignored and the number of replicas is controlled by HPA.

With the autoscaling.enabled parameter enabled, by default Autoscaling will adjust the number of replicas based on the average percentage of CPU Utilization. For other configurable Autoscaling parameters, see the Parameters table.

6.2 Manual scaling

Note: The documentserver deployments consist all the necessary dependencies in one pod.

To scale the documentserver deployment, use the following command:

$ kubectl scale -n default deployment documentserver --replicas=POD_COUNT

where POD_COUNT is a number of the documentserver pods.

7. Update ONLYOFFICE Docs

It's necessary to set the parameters for updating. For example,

$ helm upgrade documentserver onlyoffice/docs-shards \
  --set docservice.image.tag=[version]

Note: also need to specify the parameters that were specified during installation

Or modify the values.yaml file and run the command:

$ helm upgrade documentserver -f values.yaml onlyoffice/docs-shards

When the helm upgrade command is executed, replicas will be turned off one by one, and active documents on disabled replicas will be forced closed and saved. Also, disabled replicas will be removed from the Redis balancing tables.

8. Update ONLYOFFICE Docs license (optional)

In order to update the license, you need to perform the following steps:

  • Place the license.lic file containing the new key in some directory
  • Run the following commands:
$ kubectl delete secret license -n <NAMESPACE>
$ kubectl create secret generic license --from-file=path/to/license.lic -n <NAMESPACE>
  • Restart documentserver pods. For example, using the following command:
$ kubectl delete pod documentserver-*** -n <NAMESPACE>

9. ONLYOFFICE Docs installation test (optional)

You can test ONLYOFFICE Docs availability and access to connected dependencies by running the following command:

$ helm test documentserver -n <NAMESPACE>

The output should have the following line:

Phase: Succeeded

To view the log of the Pod running as a result of the helm test command, run the following command:

$ kubectl logs -f test-ds -n <NAMESPACE>

The ONLYOFFICE Docs availability check is considered a priority, so if it fails with an error, the test is considered to be failed.

After this, you can delete the test-ds Pod by running the following command:

$ kubectl delete pod test-ds -n <NAMESPACE>

Note: This testing is for informational purposes only and cannot guarantee 100% availability results. It may be that even though all checks are completed successfully, an error occurs in the application. In this case, more detailed information can be found in the application logs.

10. Access to the info page (optional)

The access to /info page is limited by default. In order to allow the access to it, you need to specify the IP addresses or subnets (that will be Proxy container clients in this case) using documentserver.proxy.infoAllowedIP parameter. Taking into consideration the specifics of Kubernetes net interaction it is possible to get the original IP of the user (being Proxy client) though it's not a standard scenario. Generally the Pods / Nodes / Load Balancer addresses will actually be the clients, so these addresses are to be used. In this case the access to the info page will be available to everyone. You can further limit the access to the info page using Nginx Basic Authentication which you can turn on by setting documentserver.proxy.infoAllowedUser parameter value and by setting the password using documentserver.proxy.infoAllowedPassword parameter, alternatively you can use the existing secret with password by setting its name with documentserver.proxy.infoAllowedExistingSecret parameter.

Using Grafana to visualize metrics (optional)

This step is optional. You can skip this section if you don't want to install Grafana

1. Deploy Grafana

Note: It is assumed that step #4.2 has already been completed.

1.1 Deploy Grafana without installing ready-made dashboards

You should skip step #1.1 if you want to Deploy Grafana with the installation of ready-made dashboards

To install Grafana to your cluster, run the following command:

$ helm install grafana bitnami/grafana \
  --set service.ports.grafana=80 \
  --set config.useGrafanaIniFile=true \
  --set config.grafanaIniConfigMap=grafana-ini \
  --set datasources.secretName=grafana-datasource

1.2 Deploy Grafana with the installation of ready-made dashboards

1.2.1 Installing ready-made Grafana dashboards

To install ready-made Grafana dashboards, set the grafana.enabled and grafana.dashboard.enabled parameters to true. If ONLYOFFICE Docs is already installed you need to run the helm upgrade documentserver onlyoffice/docs-shards --set grafana.enabled=true --set grafana.dashboard.enabled=true command or helm upgrade documentserver -f ./values.yaml onlyoffice/docs-shards if the parameters are specified in the values.yaml file. As a result, ready-made dashboards in the JSON format will be downloaded from the Grafana website, the necessary edits will be made to them and configmap will be created from them. A dashboard will also be added to visualize metrics coming from the ONLYOFFICE Docs (it is assumed that step #4 has already been completed).

1.2.2 Installing Grafana

To install Grafana to your cluster, run the following command:

$ helm install grafana bitnami/grafana \
  --set service.ports.grafana=80 \
  --set config.useGrafanaIniFile=true \
  --set config.grafanaIniConfigMap=grafana-ini \
  --set datasources.secretName=grafana-datasource \
  --set dashboardsProvider.enabled=true \
  --set dashboardsConfigMaps[0].configMapName=dashboard-node-exporter \
  --set dashboardsConfigMaps[0].fileName=dashboard-node-exporter.json \
  --set dashboardsConfigMaps[1].configMapName=dashboard-deployment \
  --set dashboardsConfigMaps[1].fileName=dashboard-deployment.json \
  --set dashboardsConfigMaps[2].configMapName=dashboard-redis \
  --set dashboardsConfigMaps[2].fileName=dashboard-redis.json \
  --set dashboardsConfigMaps[5].configMapName=dashboard-nginx-ingress \
  --set dashboardsConfigMaps[5].fileName=dashboard-nginx-ingress.json \
  --set dashboardsConfigMaps[6].configMapName=dashboard-documentserver \
  --set dashboardsConfigMaps[6].fileName=dashboard-documentserver.json \
  --set dashboardsConfigMaps[7].configMapName=dashboard-cluster-resourses \
  --set dashboardsConfigMaps[7].fileName=dashboard-cluster-resourses.json

After executing this command, the following dashboards will be imported into Grafana:

  • Node Exporter
  • Deployment Statefulset Daemonset
  • Redis Dashboard for Prometheus Redis Exporter
  • NGINX Ingress controller
  • ONLYOFFICE Docs
  • Resource usage by Pods and Containers

Note: You can see the description of the ONLYOFFICE Docs metrics that are visualized in Grafana here.

See more details about installing Grafana via Helm here.

2 Access to Grafana via Ingress

Note: It is assumed that step, please make sure that the nginx-ingress controller is installed in your cluster. If you already deploy ONLYOFFICE Docs and did not turn off the controller with the parameter ingress-nginx.enabled=false it is already present in the cluster.

If ONLYOFFICE Docs was installed with the parameter grafana.ingress.enabled (step #5.2) then access to Grafana will be at: http://INGRESS-ADDRESS/grafana/

If Ingres was installed using a secure connection (step #5.3), then access to Grafana will be at: https://your-domain-name/grafana/

3. View gathered metrics in Grafana

Go to the address http(s)://your-domain-name/grafana/

Login - admin

To get the password, run the following command:

$ kubectl get secret grafana-admin --namespace default -o jsonpath="{.data.GF_SECURITY_ADMIN_PASSWORD}" | base64 --decode

In the dashboard section, you will see the added dashboards that will display the metrics received from Prometheus.
