docker: curl: (22) The requested URL returned error: 404 Not Found for certain plugins

[jcrben]

UPDATE: this is no longer happening for now, but still interested in learning more

I noticed today that my build of the docker container stopped working due to plugins not being accessible

Looks like the same issue as #470 and maybe a couple others? Don't see anything open tho. dc61939 says "They retry will likely get another mirror" but maybe there's a way to guarantee that?

If I remove pipeline-model-definition:1.3.1 and configuration-as-code:experimental it works. Is downtime on the plugins download site tracked anywhere? Not sure about the best place for these types of issues to be tracked. Also it's not entirely clear which URL precisely is failing.

I poked around at https://updates.jenkins.io/download/plugins/ to see if I could find a missing plugin, but both workflow-steps-api (https://updates.jenkins.io/download/plugins/workflow-step-api/) and structs seem to be available.

Docker commands that you execute

Reproduction available at https://gitlab.com/jcrben-repro/jenkins-jcasc-docker - run ./builder_jenkins.sh as mentioned in the readme

Note: the repro repo uses 2.128 but I also tried the latest tag.

Actual result

Stalls out with docker: curl: (22) The requested URL returned error: 404 Not Found for certain plugins

Expected outcome

Docker container built successfully

Have you tried a non-dockerized Jenkins and get the expected outcome?

No - specifically want to use the docker version.

There are some temporary issues, something for the Jenkins INFRA team to look at

[jcrben]

NOTE: working again now

Encountering this again now with jenkins/jenkins:2.133:

Seems like there's a bug here where it's not trying a different mirror...? When I download these plugins manually from the browser, they work OK.

This is still ocurring. I have an automated build to create a jenkins blueocean image from the following Dockerfile:

FROM jenkins/jenkins:alpine

USER root

ARG user=root
ARG group=root

RUN echo http://dl-cdn.alpinelinux.org/alpine/edge/community >> /etc/apk/repositories && \
    apk -U add docker py-pip

RUN pip install docker-compose

RUN /usr/local/bin/install-plugins.sh blueocean

RUN rm -rf /var/lib/apt/lists/* \
    /var/cache/apk/* \
    /usr/share/man \
    /tmp/*

VOLUME /var/run/docker.sock

On the build I get lot's of 404 not found on plugins lke sse-gateway workflow-step-api that are internal dependencies of blueocean.

Hello, though this issue can occur from time to time, this is AFAICT not an issue that is specific to this repository. This looks like something related to the mirroring infrastructure.
As Carlos was saying above, please file an issue in the INFRA project on the Jenkins issue tracker if you want to dig more. https://issues.jenkins-ci.org/

[jcrben]

So I guess this isn't tracked anywhere? Do you mind if I open an INFRA issue, or would that just be a distraction or a duplicate?

I am having this exact same issue. Setting ATTEMPTS=3 as per the suggestion in #767 seems to solve it.
