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.

## Requirements
* Kubernetes >= 1.14
* [Helm][] >= v3.4.2
## 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 git@github.com:apache/tika-helm.git`
* Install it:
- with Helm 3: `helm install tika . --set image.tag=latest-full`
### Custom configuration for tika
To use custom [configuration]( https://tika.apache.org/2.9.1/configuring.html) values for apache tika, use the `tikaConfig` key in the `values.yaml`.
Example:
```
tikaConfig: |
