[GitHub] [solr-operator] fernaspiazu opened a new issue #364: JTS and Polygons jar file
fernaspiazu opened a new issue #364:
URL: https://github.com/apache/solr-operator/issues/364
Hi,
Is there a way to install/download the library `jts-core` in the folder `SOLR_INSTALL/server/solr-webapp/webapp/WEB-INF/lib/`? As specified in the official guide: https://solr.apache.org/guide/8_10/spatial-search.html#jts-and-polygons-flat
Actually, I tried to put in the middle an `initContainer` that downloads such jar, but I get obviously a `Permission denied` from the Solr container since only root can write on the final solr container.
I tried also to set a `securityContext` only for my `initContainer`, in order to run as root, but that configuration has no effect in the `initContainer`, I think it is not seen by the Solr CRD.
```
podOptions:
initContainers:
- name: "install-jts-core"
image: solr:8.9.0
command: ['sh', '-c', 'wget -O /opt/solr-8.9.0/server/solr-webapp/webapp/WEB-INF/lib/jts-core-1.15.1.jar https://repo1.maven.org/maven2/org/locationtech/jts/jts-core/1.15.1/jts-core-1.15.1.jar']
securityContext: <--- this has no effect on SolrCloud CRD
runAsUser: 0
```
Another disperate attempt was to set a `podSecurityContext.runAsUser: 0`, so for all containers in the pod, but Solr does not run as `root`, I discarded that option by the way.
Any hint/idea/solution please?
Thank you very much in advance.

Seeing two people independently try to do this (and its awkward) makes me wonder if Solr should finally ship with JTS. There used to be a license issue many years ago but no longer an issue. https://issues.apache.org/jira/browse/SOLR-11953
Annoyingly, due to the way JTS is referenced via Spatial4j via Lucene, it has to go in WEB-INF/lib, not in a solr/lib

Hi @HoustonPutman,
Thank you very much for your answer.
I have recently found a solution that may not be elegant, but works well in any version of Solr image, below a configuration example:
```yaml
podOptions:
initContainers:
- name: "install-jts-lib"
image: solr:8.9.0
command:
- 'sh'
- '-c'
- |
wget -O /tmp-webinf-lib/jts-core-1.15.1.jar https://repo1.maven.org/maven2/org/locationtech/jts/jts-core/1.15.1/jts-core-1.15.1.jar
cp -R /opt/solr/server/solr-webapp/webapp/WEB-INF/lib/* /tmp-webinf-lib
volumeMounts:
- mountPath: /tmp-webinf-lib
name: web-inf-lib
volumes:
- name: web-inf-lib
source:
emptyDir: {}
defaultContainerMount:
name: web-inf-lib
mountPath: /opt/solr/server/solr-webapp/webapp/WEB-INF/lib
```
In this example, I create an `emptyDir` volume, attach it in any directory of the `initContainer`, but in the `target directory` of the final Solr image, this will empty the `WEB-INF/lib` directory, but since I'm using the same Solr image, I can copy the content of `WEB-INF/lib` (jars and folders) at the end.
The effect is that the final container will have all the content it should have had plus the `jts-core-1.15.1.jar` jar.
This works also with other files or libraries you want to bring in the Solr container.
Let me know what do you thing of this workaround 👍
Thank you again.

For those who might be interested in an alternative to @fernaspiazu's trick, here's how I did it:
```
lifecycleHooks:
postStart:
exec:
command:
- /bin/sh
- -ceux
- >
jts_version=1.18.2 &&
dir=/opt/bitnami/solr/server/solr-webapp/webapp/WEB-INF/lib &&
test -f ${dir}/jts-core-${jts_version}.jar ||
curl -o ${dir}/jts-core-${jts_version}.jar https://repo1.maven.org/maven2/org/locationtech/jts/jts-core/${jts_version}/jts-core-${jts_version}.jar
```
Although it works fine for me in practice, this solution probably relies on the `postStart` being called _before_ the app starts up.
And no such guarantee in terms of timing exists as far as I can read on <https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/>.
> This hook is executed immediately after a container is created. However, there is no guarantee that the hook will execute before the container ENTRYPOINT.
So your mileage may vary.

Hello @fernaspiazu, this is a good question.
Starting with Solr Operator `v0.5.0`, you should be able to do the following:
1. Use the init container, and save it in an empty-dir volume. Mount this volume into your init-container at any location. 2. Mount this emtpy-dir jar volume in your Solr container, somewhere under the data path (`/var/solr/data/libs`).
3. Then use `SolrCloud.spec.additionalLibs=['/var/solr/data/libs']`. (Note this will only work for more recent solr versions, but that is fine since you are running `8.9.0`.
I recognize that the Solr documentation says the Jar has to be placed in WEB_INF/lib, but I really don't think that's possible given the Solr docker image.
Give this a try and let me know if it works.

I close this issue, till another similar use case appears.
Thanks again.
