Question

我有一个 Docker 镜像，我想在本地运行，但我认为它失败是由于 Qemu 的问题，这似乎源于试图在 M1 芯片上运行 Cypress：

REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
dna          local     097c5f291db5   2 hours ago   3.66GB

当我尝试使用 docker run dna:local 在本地运行图像时，我得到以下信息：

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
yarn run v1.22.10

我的 Dockerfile 如下所示：

FROM cypress/browsers:node14.16.0-chrome90-ff88

# Copy the project into the Docker container
COPY . /

# Install the API and UI packages
RUN yarn workspace checkin-api install
RUN yarn workspace checkin-ui install

# Run the e2e test suite
CMD yarn run e2e

奇怪的是，如果我尝试为镜像指定平台，Docker 会抱怨在本地找不到镜像：

docker run --platform linux/arm64/v8 dna:local

为我提供以下信息：

Unable to find image 'dna:local' locally
docker: Error response from daemon: pull access denied for dna, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

我假设从 Cypress Docker 存储库中提取的图像决定了所使用的架构，而不是我的 --platform 标志？如果是这样，这仅仅是因为 Cypress 不会在我机器上的 Docker 容器中运行吗？

Answer 1

您可能需要使用为 M1 / Apple Silicon 构建的 Docker 版本。

https://docs.docker.com/docker-for-mac/apple-silicon/

要尝试的另一件事是使用平台构建它，然后运行它。

docker build -t dna:local --platform linux/arm64/v8 .

看起来 Cypress 的 Docker 容器存在一个已知问题，无法与 M1 芯片一起正常工作：

https://github.com/cypress-io/cypress-docker-images/issues/431

由于 M1 芯片上的 Qemu 错误，Docker/Cypress 容器失败
