tika: The official Helm chart to deploy Apache Tika on Kubernetes

— Open in Artifact Hub

<script async src="https://artifacthub.io/artifacthub-widget.js"></script>

A Helm chart to deploy Apache Tika on Kubernetes.

This Helm chart is a lightweight way to configure and run the official apache/tika Docker image.

We recommend that the Helm chart version is aligned to the version Tika (and subsequently the version of the Tika Docker image) you want to deploy. This will ensure that you using a chart version that has been tested against the corresponding production version. This will also ensure that the documentation and examples for the chart will work with the version of Tika you are installing.

Warning: This branch is used for development, please use the latest release for released version.

Installing

Install released version using Helm repository

N.B. You may or may not need/wish to install the chart into a specific namespace, in which case you may need to augment the commands below.

• Add the Tika Helm charts repo: helm repo add tika https://apache.jfrog.io/artifactory/tika

• Install it:

  • with Helm 3: helm install tika tika/tika --set image.tag=${release.version} -n tika-test, you will see something like

helm install tika tika/tika --set image.tag=latest-full -n tika-test

...
NAME: tika
LAST DEPLOYED: Mon Jan 24 13:38:01 2022
NAMESPACE: tika-test
STATUS: deployed
REVISION: 1
NOTES:
1. Get the application URL by running these commands:
  export POD_NAME=$(kubectl get pods --namespace tika-test -l "app.kubernetes.io/name=tika,app.kubernetes.io/instance=tika" -o jsonpath="{.items[0].metadata.name}")
  export CONTAINER_PORT=$(kubectl get pod --namespace tika-test $POD_NAME -o jsonpath="{.spec.containers[0].ports[0].containerPort}")
  echo "Visit http://127.0.0.1:9998 to use your application"
  kubectl --namespace tika-test port-forward $POD_NAME 9998:$CONTAINER_PORT

You may notice that the kubectl port forwarding experiences a timeout issue which ultimately kills the app. In this case you can run port formarding in a loop

while true; do kubectl --namespace tika-test port-forward $POD_NAME 9998:$CONTAINER_PORT ; done

... this should keep kubectl reconnecting on connection lost.

Install development version using master branch

• Clone the git repo: git clone [email protected]:apache/tika-helm.git

• Install it:

  • with Helm 3: helm install tika . --set image.tag=latest-full
