The WHL format was developed as a faster, more reliable way to install Python software, rather than rebuilding it from source every time. Just move the WHL file to the correct location on the target system to install, whereas source distribution requires build steps prior to installation.

Reference: github.com/jfloff/alpi…

Images based on the Alpine platform do not support roundpacks pandas and Numpy. This is why when we installed them using Python PIP during the build, we always compiled them from Alpine’s source file. Unfortunately, the only way to install Pandas on Alpine’s image is to wait until the build is complete. It can only be compiled and then installed, and can be used as a base image

If the container running docker build needs to access the Internet through the proxy, add the command line before the operation required to access the network in the file:

Export http_proxy = http://16.15.0.1:9011

And:

Export https_proxy = http://16.15.0.1:9011

If there is an error at runtime:

Solution:

———- If Centos8 cannot resolve the domain name:

# add firewall configuration:

#firewall-cmd --zone=public --add-masquerade --permanent
#firewall-cmd --reload
#systemctl restart docker
