Este teste, outro teste de servidor não é problema. Há um problema no servidor criado pela empresa através do espelhamento virtual, e suspeita-se que seja configuração
Visualize a configuração de dns do próprio ambiente linux
cat /etc/resolv.conf
#
nameserver 218.1.23.333
Entre em /etc/docker/
cd /etc/docker
Modifique o arquivo daemon.json (adicione a configuração de DNS) da seguinte maneira
{
"insecure-registries": ["218.1.23.333:8089"],
"registry-mirrors": ["https://4xtasccp.mirror.aliyuncs.com"],
"dns":["218.1.23.333"]
}
recarregar arquivo de configuração
systemctl daemon-reload
Reinicie a janela de encaixe para entrar em vigor
systemctl restart docker
Recrie a imagem do python
Terminar
