### Containers

#### Template

First download a template : dc > node > local > CT Templates > Templates

Choose one distribution that you know, like *Ubuntu 22.04*.

#### Create a container

At the top right GUI : *Create CT*. Fill in all the forms.

#### Connect to SSH

From GUI, open a terminal on your container. Allow root login with password if needed (don't do that in prod) by modifying `/etc/ssh/sshd_config` on your container. Then start sshd with `systemctl start ssh`. Get the IP with `ip a`.

Ssh to your node first. Try to ping your container with the address you just got. Then ssh to your container from your node shell.

For example :

```sh
me@my-laptop ssh root@192.168.122.34
root@node1 ssh root@fe80::c7f:7dff:fec6:d09e%vmbr0
root@ct1 echo success
```

#### Trouble shoot container Internet connexion

Good question. Still does not work on my container. :'(

DNS : 192.168.122.1 -> 192.168.1.1 (l'adresse de la box)
Et mettre DHCP sur l'adresse IP ... et ça marche !

(Une IP fixe devrait marcher)

#### Trouble shoot container having DNS but does not reach Internet

Set the right gateway to the next thing.

For the ISF practice session, it was on the linux bridge.
