Issues Authenticating to Private Registry (Nexus)

[hermanmaleiane]

Hope you’re doing well.

I’m facing an issue while trying to run the pod falcon-shra-executor-0.
The problem occurs when I configure my private Nexus registry.

Below is the error log:

time=2025-11-04T13:50:34.031562Z name=registryassessmentexecutor level=Debug legacy_level=[DEBUG] caller=docker/docker.go:1254 msg="Requesting token with credentials" auth_url="Sonatype Nexus Repository Manager"

I’ve confirmed that I can successfully log in to the Nexus registry using the following commands:

DOCKER_USERNAME=NEXUS_USERNAME
DDOCKER_PASSWORD='NEXUS_PASSWORD
REGISTRY=nexus-12:8443

echo $DOCKER_PASSWORD | docker login -u $DOCKER_USERNAME $REGISTRY --password-stdin

My kubernetes secret

kubectl create secret docker-registry nexus-regcred --docker-server='nexus-12:8443' --docker-username='NEXUS_USERNAME' --docker-password='NEXUS_PASSWORD' -n falcon-shra

Is there anything I might be missing in the configuration?
