Build failing due to failing COPY directive in Dockerfile

Support

I’m trying to build an Okteto manifest for my application. I’ve simplified it as much as possible, but the COPY directives in my Dockerfile are failing without an obvious error. Relevant lines:

$ okteto build
...
 => CACHED [ 2/17] WORKDIR /app                                                                                                                        0.0s
 => ERROR [ 3/17] COPY ./generic/web/config/apache2 /etc/apache2                                                                                       0.0s
 => CACHED [ 4/17] RUN mv "/usr/local/etc/php/php.ini-production" "/usr/local/etc/php/php.ini"                                                         0.0s
 => ERROR [ 5/17] COPY ./generic/web/config/php/proprietary.ini /usr/local/etc/php/conf.d/                                                                 0.0s
...

The manifest is pretty simple at this point:

build:
  generic-web:
    context: src/generic/web
    dockerfile: Dockerfile

In the process of tracking down logs, I found the logs for the buildkit container:

$ k -n okteto logs pods/okteto-okteto-enterprise-buildkit-0 | tail
time="2022-08-18T14:36:36Z" level=info msg="running server on [::]:1234"

Are there any other logs that might be relevant for figuring out what’s going on? Thanks.

Thanks to Okteto personnel for helping resolve the problem. The issue was an incorrect context in my Okteto manifest. My Dockerfile is written with the expectation that the context will be src in my repository, but my manifest was passing it src/generic/web. The build was successful after rewriting my manifest like this:

build:
  generic-web:
    context: src
    dockerfile: generic/web/Dockerfile

Thanks again!
