Installing with Dockerfile (FROM alpine:3.7), Dockerfile works fine two month ago, but now failed without modified Dockerfile.

Dockerfile's commands:

apk add --no-cache --virtual=.build-deps build-base linux-headers python3-dev==3.6.5-r0 zlib-dev openblas-dev apk add --no-cache --virtual=.run-deps dumb-init bash vim tini ca-certificates python3==3.6.5-r0 openblas libstdc++ libaio libnsl

build logs:
