Ubuntu 16.04 ：在 dockerfile 中运行"apt-get update "命令时出现错误"Could not connect to archive.ubuntu.com:80 (9

我将对我的问题进行如下处理：

我想为Hyperledger Indy-sdk构建一个docker镜像
在构建docker镜像时，它使用docker compose命令来构建两个镜像并将其组合，即indy池镜像和入门镜像。我的docker-compose.yml文件如下所示

version: '2'
services:
indy_pool:
build:
context: ../../ci/
dockerfile: indy-pool.dockerfile
args:
pool_ip: '10.0.0.2'
image: indy_pool
container_name: indy_pool
working_dir: /home/indy
ports:
- "9701:9701"
- "9702:9702"
- "9703:9703"
- "9704:9704"
- "9705:9705"
- "9706:9706"
- "9707:9707"
- "9708:9708"
networks:
pool_network:
ipv4_address: 10.0.0.2
volumes:
- sandbox:/var/lib/indy/sandbox/
jupyter:
build:
context: .
dockerfile: getting-started.dockerfile
command: jupyter notebook --ip=0.0.0.0
image: getting-started
container_name: getting_started
working_dir: /home/indy
volumes:
- ./getting-started.ipynb:/home/indy/getting-started.ipynb
- sandbox:/home/indy/sandbox
ports:
- "8888:8888"
networks:
- pool_network
links:
- indy_pool
networks:
pool_network:
driver: bridge
ipam:
driver: default
config:
-
subnet: 10.0.0.0/24
volumes:
sandbox:

上述docker compose将启动indy-pool.dockerfile以运行。indy-pool.dockerfile的内容如下所示

现在Ubuntu 16.04镜像和indy池镜像都将成功创建，如图所示Ubuntu 16.04和Indy池成功截图
在此之后，当启动时。docker文件开始运行。获取staretd.dockerfile看起来像这个

FROM ubuntu:16.04
RUN useradd -ms /bin/bash indy

&& apt-get update 
&& apt-get install -y 
libindy=1.11.0
USER indy
EXPOSE 8888

当在getting-started.dokerfile中执行RUN apt-get-update-y时，整个问题就开始了

注意：我的docker引擎和docker compose安装在Ubuntu 20.04之上

为了解决这个问题，我访问了互联网上的多个可用资源。由此我可以说这不是DNS查找和http代理的问题(因为我不在代理网络中工作(。

由于我是Docker构建和Docker撰写的新手，我坚信这与图像构建过程有关。如果你们中的任何人遇到类似的问题并解决了它，请向我提供解决上述问题的建议。

尝试使用选项--network=host构建依赖关系，并能够使用indy SDK 创建图像

docker build --network=host -t indy-image .

可能是代理问题
您可以将docker代理配置设置为~/.docker/config.json
在docker文档中对此进行了解释。
