在gitlab ci中存储docker镜像的位置是什么？

Question

我已经成功地构建了一个docker镜像，并将其标记为testdock:latest ($CI_REGISTRY_IMAGE:latest)，$CI_REGISTRY变量保存在GitLab项目变量中。

我还有另一个阶段，开始使用Trivy扫描testdock图像:这个过程停滞不前，没有任何进展。我猜是找不到图像，或者GitLab中的docker环境有问题。

   Where is the `docker image (testdock)` stored?

这是我用来让Trivy扫描testdock镜像的命令：

$ TRIVY_INSECURE=true trivy --skip-update --output "$CI_PROJECT_DIR/scanning-report.json"  $CI_REGISTRY_IMAGE:latest

yml：

Answer 1

所有作业都是独立运行的。因此，只要您不专门告诉作业使用artifacts指令将其传递到下一个作业，jobA通常就不知道jobB生成了什么。

在你的例子中，你是在你的工作中建立你的形象，但如果你不推动它-它将就像任何丢弃的数据一样，在下一阶段丢失。最简单的方法是将其推送到docker注册表，并从那里使用它。例如：一种常见的做法是用提交SHA而不是最新的来标记它。这样你就可以确保你总是找到正确的图像。

最后的gitlan-ci.yml现在运行得很好：

variables:
  # Tell docker CLI how to talk to Docker daemon.
  DOCKER_HOST: tcp://localhost:2375/
  # Use the overlayfs driver for improved performance.
  DOCKER_DRIVER: overlay2
  # Disable TLS since we're running inside local network.
  DOCKER_TLS_CERTDIR: ""
