For anyone interested in a guide.
1. Create a custom `web.xml`
- Get the default web.xml from solr's repository or from your container
at `/opt/solr-9.7.0/server/solr-webapp/webapp/WEB-INF/web.xml` ( make sure to
put the correct version )
- follow https://laurenthinoul.com/how-to-enable-cors-in-solr/ to do the
required changes
2. Create a ConfigMap that contains the new web.xml file. You can do this by
running the following command:
```bash
kubectl create configmap custom-web-xml
--from-file=web.xml={{path/to/your/web.xml on machine running kubectl}}
```
3. Attach a volume to solr containers
In SolrCloud resource file, create a new volume under
`SolrCloud.spec.customSolrKubeOptions.podOptions.volumes` as follows:
```yaml
# specs:
https://apache.github.io/solr-operator/docs/solr-cloud/solr-cloud-crd.html
apiVersion: solr.apache.org/v1beta1
kind: SolrCloud
metadata:
name: search-cluster
spec:
# <new config>
customSolrKubeOptions:
podOptions:
# override /opt/solr-9.7.0/server/solr-webapp/webapp/WEB-INF/web.xml
with custom web.xml to enable CORS
volumes:
- name: custom-web-xml-volume
source:
configMap:
name: custom-web-xml
items:
- key: web.xml
path: web.xml
defaultContainerMount:
name: custom-web-xml-volume
mountPath:
/opt/solr-9.7.0/server/solr-webapp/webapp/WEB-INF/web.xml # ! match solr version
subPath: web.xml
readOnly: true
# </new config>
# rest of the file ....
replicas: 2
solrJavaMem: -Xms512M -Xmx1G
solrImage:
tag: 9.7.0
```
4. Apply changes
5. Verify
get one of your pods' names, and verify that it has the new xml file:
```bash
kubectl exec -it <solr-pod-name> -- cat
/opt/solr-9.7.0/server/solr-webapp/webapp/WEB-INF/web.xml
```
