Mengakses internet di dalam wadah di belakang proxy perusahaan

Saya menjalankan daemon docker di windows dan telah mengkonfigurasi daemon saya untuk menggunakan proxy menggunakan nama pengguna dan kata sandi saya. Saya berhasil menarik ubuntu:latestgambar dari hub docker, tetapi begitu SSH meletakkan kontainer dan mencoba apt update, itu tidak berhasil. Suatu hal yang menarik untuk diperhatikan adalah bahwa ia mencoba terhubung ke server Repo Ubuntu secara langsung.

Saya kemudian mengkonfigurasi apt.conffile dan mulai menggunakan proxy tetapi, karena alasan tertentu, otentikasi gagal. Saya telah memeriksa dan mengecek ulang bahwa sintaks dan kata sandi saya sudah benar.

Saya menghapus apt.conffile dan mengkonfigurasi proxy di http_proxydan https_proxyvariabel lingkungan tetapi masih sama. Kegagalan otentikasi.

Saya mencoba menggunakan keduanya, dan sekali lagi, kegagalan otentikasi. Inilah yang saya dapatkan:
