Splunk Operator: OpenJDK Functionality baked into Operator

[skirven4]

Please select the type of request

Feature Request

Tell us more

Describe the request

• Unable to get OpenJDK 11 to run in the current deployment with the operator. (Yes, I have reviewed closed issues).

Expected behavior

• Be able to set a flag to install OpenJDK on the Operator to help support apps such as DB Connect.

Splunk setup on K8S

• Splunk Operator 2.3.0 is running on Prem on Google Anthos

Reproduction/Testing steps

• Steps to reproduce the bug. For an enhancement or feature request, please provide steps to test.
  • When I added the JAVA_VERSION=openjdk:11 to the deployment, I got the same issue with sudo reported in https://github.com/splunk/splunk-operator/issues/859.
  • There is also an image for 9.0.3 with the openjdk tag, but, according the Operator documentation, that would not be supported, and we're also on 9.0.4.1 now. Would it be possible to rebuild into the other versions?

K8s environment

• Useful information about the K8S environment being used. Eg. version of K8s, kind of K8s cluster etc..
• Unknown version of Kubernetes, but supposedly, I have full admin access to the Anthos cluster provided to me. There could be restrictions on running things as root, which is why sudo may be required.

• Proposed changes(optional)

• Proposed change, if any.
• Allow for OpenJDK to be installed.

K8s collector data(optional)

• Please provide data collected from the K8s collectors, if any.

Additional context(optional)

• Add any other context about the problem here.

I tested this on operator 2.5.2 and found: │ TASK [splunk_common : include_tasks] *** │ │ included: /opt/ansible/roles/splunk_common/tasks/install_java.yml for localhost │ │ Tuesday 30 April 2024 05:18:59 +0000 (0:00:00.062) 0:00:06.076 * │ │ Tuesday 30 April 2024 05:18:59 +0000 (0:00:00.023) 0:00:06.099 │ │ Tuesday 30 April 2024 05:18:59 +0000 (0:00:00.023) 0:00:06.123 │ │ │ │ TASK [splunk_common : Install Openjdk11 JDK] *** │ │ included: /opt/ansible/roles/splunk_common/tasks/java_tasks/install_openjdk11_jdk.yml for localhost │ │ Tuesday 30 April 2024 05:18:59 +0000 (0:00:00.047) 0:00:06.170 * │ │ │ │ TASK [splunk_common : Create a dependency file] **** │ │ fatal: [localhost]: FAILED! => { │ │ "changed": false, │ │ "rc": 1 │ │ } │ │ │ │ MSG: │ │ │ │ MODULE FAILURE │ │ See stdout/stderr for the exact error │ │ │ │ │ │ MODULE_STDERR: │ │ │ │ sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges? │ │ │ │ │ │ PLAY RECAP ***** │ │ localhost : ok=24 changed=0 unreachable=0 failed=1 skipped=26 rescued=0 ignored=0 │

My workaround will be to attempt to get a portable java deployed into the search heads

@gjanders , we tried with search heads and we face the same error Can u share the steps which u performed for search heads ?

[gjanders]

@Hariprasath-3091 we uploaded an entire java JDK into the S3 bucket and had it deployed by the AppFramework
