Building Docker Image Using Kaniko tls_process_server_certificate:certificate verify failed

I am trying to build a custom alpine docker image using Kaniko. When I attempt to use the APK package manager to download package, I see the following ssl error.

:SSL routines:tls_process_server_certificate:certificate verify failed:ssl/statem/statem_clnt.c

Note that I am behind an enterprise proxy. I have already provided Kaniko with certificate bundles and proxy settings. That is why I am able to pull alpine images from docker hub.

ARG HTTP_PROXY
ARG HTTPS_PROXY

FROM alpine:3.13.2

ENV http_proxy=$HTTP_PROXY
ENV https_proxy=$HTTPS_PROXY

RUN apk update

What is the issue with the SSL in this case, and how can I configure the APK/Docker to ensure I am able to download packages?

Solution

  • The issue was not due to configuration. The issue was due to alpine image. There is a bug with 13.3.2.

    I reverted my image to alpine3.12.
