Which configuration should I change for set specific NIC for HDFS data-node data replication? I want to separate traffic for Service between Replication.

I have got the reason why because of certification problem of runtime manager pod. fetch image metadata failed data = {"err":"parseImageSourceFailed : error pinging docker registry harbor.hadoop.com: Get \"https://harbor.hadoop.com/v2/\": x509: certificate signed by unknown authority","url":"harbor.hadoop.com/cloudera/cdsw/ml-runtime-jupyterlab-python3.11-standard:2024.02.1-b4"} CA already registered on system. I created the secret "regcred". I put the file "k8s-secret-regcred.yaml" on /etc/cdsw/patches. I entered CA into Root CA Configuration of [Site-administration] - [Security] How can I solve this issue?

I tried steps below. 1. Installed harbor. (aaa.bbb.ccc) 2. Created new image use the dockerfile and command below -------- FROM aaa.bbb.ccc/cloudera/cdsw/ml-runtime-jupyterlab-python3.10-standard:2023.08.2-b8 RUN apt-get update && apt-get upgrade -y && apt-get clean && rm -rf /var/lib/apt/lists/ # Cloudera metadata for CML ENV ML_RUNTIME_EDITION="EDITED RUNTIME" \ ML_RUNTIME_SHORT_VERSION="0.1" \ ML_RUNTIME_MAINTENANCE_VERSION=1 \ ML_RUNTIME_DESCRIPTION="EDITED RUNTIME to test" ENV ML_RUNTIME_FULL_VERSION="${ML_RUNTIME_SHORT_VERSION}.${ML_RUNTIME_MAINTENANCE_VERSION}" LABEL com.cloudera.ml.runtime.edition=$ML_RUNTIME_EDITION \ com.cloudera.ml.runtime.full-version=$ML_RUNTIME_FULL_VERSION \ com.cloudera.ml.runtime.short-version=$ML_RUNTIME_SHORT_VERSION \ com.cloudera.ml.runtime.maintenance-version=$ML_RUNTIME_MAINTENANCE_VERSION \ com.cloudera.ml.runtime.description=$ML_RUNTIME_DESCRIPTION --------- docker build -t aaa.bbb.ccc/cloudera/cdsw/ml-runtime-jupyterlab-python3.10-standard:2023.08.2-b8-20240509 . push aaa.bbb.ccc/cloudera/cdsw/ml-runtime-jupyterlab-python3.10-standard:2023.08.2-b8-20240509 3. Created secret kubectl create secret docker-registry regcred --docker-server=aaa.bbb.ccc --docker-username=admin --docker-password=PASSWORD -n default 4. Tried adding the runtime image [Runtime Catalog] - [+Add Runtime] put "aaa.bbb.ccc/cloudera/cdsw/ml-runtime-jupyterlab-python3.10-standard:2023.08.2-b8-20240509" and push [validate] then i faced the message "Could not fetch the image metadata." Which procedure did you miss? To use private registry without using such as harbor, How can I push into it?

Yes, I created custom certs based on custom ca cert. At lease even if on RHEL 8.4, provisioning has succeded if certs are right. Thank you. @upadhyayk04

@upadhyayk04 Same issue happened on all of them (1.5.2, 1.5.3, 1.5.3-h1) I guess one of two kinds of reasons. The first one is related Certification. I think If certification aint right then it happened. (for example server cert doesnt match with ca cert) [Update Ingress Controller Certificate] action failed in this case. And second is DNS. Looks It happened I more than one nameserver lists in /etc/resolv.conf. In this case might related Certificate.

@upadhyayk04 I have got the reason why because of iscsi problem. I think actually It will not happen in normal cases because no one try to re-install if It installed successfuly. Anyway to solve this problem, I had to delete all related iscsi, and iscsi pacakges before re-install. Thank you.

Thankyou for your answer. I asked about support 1.5.3 on rhel 8.4
