由于 gcc 错误，Python docker 映像构建失败

Question

I am studying Nornir and want to containerize my application, here is the Dockerfile content:

FROM alpine

RUN apk update && apk upgrade 
RUN apk add gcc && apk add py3-pip && apk add libevent-dev
RUN apk add python3-dev && pip3 install nornir 

When I build the container with the command:

docker build --network=host .

I get the following errors:

somaiia@main-srv:~/core/nornir$ docker build --no-cache --network=host .
Sending build context to Docker daemon  10.24kB
Step 1/4 : FROM alpine
...
Step 4/4 : RUN apk add python3-dev && pip3 install nornir

I am unable to build Nornir and can't proceed with the next steps as a result, what can I do?

Answer 1

In the logs the error originates from this

Collecting ruamel.yaml.clib>=0.2.6
  Downloading ruamel.yaml.clib-0.2.6.tar.gz (180 kB)
    **ERROR: Command errored out with exit status 1:

But following the logs we this

Collecting ruamel.yaml.clib>=0.1.2
   Downloading ruamel.yaml.clib-0.2.2.tar.gz (179 kB)

Basically the first dependeny requirement demanded the ruamel.yaml.clib version to be greater or equal to 0.2.6 , but it failed.

In the next try it tried for a version greater or equal to 0.1.2 .

In the final logs we see

Successfully installed ... nornir-3.3.0 ruamel.yaml.clib-0.2.2 ...**

Meaning it successfully installed an older version of ruamel.yaml.clib library and finally installed the nornir library as well
