Jenkins fails - Failed with status: 404 Not Found

[MK]

Hello Team,

My environment as follows.

Jenkins Version - 2.227.1(LTS).

OS - CentOS - 8.2

SonaType Nexus - OSS 3.21.2-0.

For the docker private registry purpose as the instructions provided in the below link[1], i have configured. However instead of http i have enabled https using self-signed method using below link[2].

[1] - https://blog.sonatype.com/using-nexus-3-as-your-repository-part-3-docker-images

[2] - https://support.sonatype.com/hc/en-us/articles/213465768#generate-self-signed

In jenkins i have installed docker plugin and Manage Jenkins > Configure Systems > Declarative Pipeline (Docker) - Docker registry URL (I have provided our private registry)

Example URL - https://private-nexus.company.net/nexus and credentials.

Now when i run my declarative pipeline job to pull a public image from dockerhub i am getting below error.

pipeline

   { 

     agent

        {

        docker

         {

  image 'ubuntu:latest'

  label "jenkins-slave-01"

 }

}

------

Using the existing docker config file.Removing blacklisted property: auths$ docker login -u test -p ******** https://private-nexus.company.net/nexus
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: login attempt to https://private-nexus.company.net/v2/ failed with status: 404 Not Found

Still any configuration i need to enable from nexus side? i am not sure why it is going to v2 endpoint.

On build system terminal i am able to login our private registry(nexus & docker hub).

All docker client requests end up at either some path under /v2 or /v1 because that is the official Docker API. You cannot ask docker client to sends requests to a webapp context path /nexus or even /nexus/v2 , directly.

Suggest upgrading to the most recent version of NXRM and also reviewing our official help:

Thanks Peter.  I have resolved the issue by going to Manage Jenkins > Configure Systems > Declarative Pipeline (Docker) - Docker registry URL = Removed our local registry URL.

Yes sure we will upgrade to recent version as soon as possible.
