容器 `cmd.cat/lspci` 超时

Question

我在一些测试中使用了

cmd.cat/lspci

容器。 今天突然开始失败。

docker run cmd.cat/lspci
Unable to find image 'cmd.cat/lspci:latest' locally
docker: Error response from daemon: Get "https://cmd.cat/v2/": context deadline exceeded (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.

连接似乎响应约 20 秒。

我尝试了本地和多个服务器，但出现了同样的问题。有没有办法增加

docker run

或

docker pull

或其他带有

lspci

的公共 docker 镜像的超时。

Answer 1

Dockerfile

# Use an official Ubuntu base image
FROM ubuntu:latest

# Update packages and install pciutils
RUN apt-get update && apt-get install -y pciutils

# Set the default command to run when starting the container
CMD ["bash"]

最终构建了我自己的容器。
