Question

我有一个以.p开头的Dockerfile

FROM python:3.7-slim

RUN mkdir -p /usr/share/man/man1mkdir -p /usr/share/man/man1
RUN apt-get update && apt-get install -y openjdk-8-jdk

在本地，这很完美。因此，我将.gitlab-ci.yml文件编写如下：

docker-image:
  stage: containerise_requirements
  image: docker:19.03.1
  tag:
    - my-runner
  services:
    - docker:19.03.1-dind
  variables:
    DOCKER_TLS_CERTDIR: ""
  script:
    - docker pull $IMAGENAME:latest || true
    - docker build --cache-from $IMAGENAME:latest --tag $IMAGENAME:$CI_COMMIT_SHA --tag $IMAGENAME:latest .
    - docker push $IMAGENAME:$CI_COMMIT_SHA
    - docker push $IMAGENAME:latest

但是现在，我得到了错误

Sending build context to Docker daemon  1.031MB

E: Unable to locate package openjdk-8-jdk

这让我感到惊讶-如果Dockerfile在本地构建，为什么它不在CI期间构建？

Answer 1

Python：3.7-slim现在基于Debian10。没有这样的软件包openjdk-8-jdk。因此，要么安装openjdk-11-jdk，要么添加sid Repo源。很有可能您的本地Python映像较旧，因此基于较旧的Debian（例如Stretch）。

Dockerfile在本地运行良好，但在.gitlab-ci.yml中无法正常运行
