docker - 构建器的 Gitlab CI 拉取访问被拒绝，存储库不存在或可能需要 'docker login'

Question

我有下一个构建脚本

echo 'Login'
sudo docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY

echo 'Build the project'
sudo docker build -t builder -f BuilderDockerfile .

echo 'Build the deployment containers'
sudo docker build -t $CI_REGISTRY_IMAGE/server:dev -f ApiDockerfile . & 
wait

echo 'Push the new images'
sudo docker push $CI_REGISTRY_IMAGE/server:dev &
wait

BuilderDockerfile 在哪里

FROM microsoft/dotnet:2.1-sdk as dotnet_build

RUN echo 'BuilderDockerfile preparations'
WORKDIR /usr/src/app
COPY ./All_In .
RUN dotnet restore
RUN dotnet publish -c Release

FROM alpine:3.5
COPY --from=dotnet_build /usr/src/app /usr/src/dotnet_app

ApiDockerfile 是

FROM microsoft/dotnet:2.1-aspnetcore-runtime

RUN echo 'ApiDockerfile preparations'
COPY --from=builder /usr/src/dotnet_app /usr/src/app

RUN echo 'ApiDockerfile run'
WORKDIR /usr/src/app/All_In.Server/bin/Release/netcoreapp2.1
CMD [ "dotnet", "./All_In.Server.dll" ]

我还配置了 gitlab-runner 并选择了 shell 执行器。结果在这个构建过程中我有下一个输出

The push refers to repository [registry.gitlab.com/crispried/all-in-backend/server]
An image does not exist locally with the tag: registry.gitlab.com/crispried/all-in-backend/server
Job succeeded

所以，第一个错误是 复制失败:stat/var/lib/docker/tmp/docker-builder533733656/All_In:没有那个文件或目录

但是，我不明白为什么会出现。结果是

sudo docker build -t builder -f BuilderDockerfile .

第二个是来自标志值构建器的无效:构建器的拉取访问被拒绝，存储库不存在或可能需要“docker login” 推送指的是存储库 [registry.gitlab.com/crispried/all-in-backend/server] 本地不存在带有标签的图像:registry.gitlab.com/crispried/all-in-backend/server

我相信这是第一个错误的结果，对吧？任何想法如何解决它？在我使用较旧的 netcore 图像的另一个项目中，类似的配置对我很有用。我是否遗漏了配置中的某些内容？

Answer 1

问题出在这行构建 Step 3/7 : COPY ./All_In .

我错过了在这个项目中我的构建脚本在我的项目根文件夹中。所以，实际上我的项目中没有 ./All_In 文件夹。在我的案例中，解决方案只是修改 BuilderDockerfile:

改变

COPY ./All_In .

到

COPY . .

作为结论 - 当您从其他项目复制一些脚本时要小心。
