Hi Jerems

You can install packages via pip in guestshell:

[guestshell@guestshell ~]$ sudo pip3 install requests

WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

To do so i need to provide with internet access to guestshell which seems impossible at the moment.

My guestshell runs on top of a Cisco ISR1111 version 16.12.04.

By the way, let me double check with google if i can find out a way to fix this.

Yes, either internet access or you host your own repo somewhere accessible by the router (https://packaging.python.org/en/latest/guides/hosting-your-own-index/)

Hello dear community,

If you plan to provide with Internet access to your Guestshell container please follow this procedure :

Configure interface VirtualPortGroup0 (GW for the container):

interface VirtualPortGroup0
 ip address 192.168.1.1 255.255.255.0
 ip nat inside
 no mop enabled
 no mop sysid

Configure interface GigabitEthernet0/0/0.13 (My "WAN" interface"):

interface GigabitEthernet0/0/0.13
 description Lien vers Jeyniper01 - vlan Internet
 encapsulation dot1Q 13
 ip address 192.168.13.2 255.255.255.252
 ip nat outside

 Configure NAT :

ip nat inside source list GUESTSHELL-NAT-ACL interface GigabitEthernet0/0/0.13 overload
ip access-list extended GUESTSHELL-NAT-ACL
 10 permit ip 192.168.1.0 0.0.0.255 any

And the app-hosting part:

app-hosting appid guestshell
 app-vnic gateway0 virtualportgroup 0 guest-interface 0
  guest-ipaddress 192.168.1.2 netmask 255.255.255.0
 app-default-gateway 192.168.1.1 guest-interface 0
 name-server0 192.168.0.252
 name-server1 192.168.0.250
