Configure Debian

Lets configure Debian 9 OS to run our Docker containers. We are going to use it as our staging server.

First download Debian distribution. Then install that into your virtual box. Just ssh and headless mode will be fine. Create at least 4GB disc.

Then we can do basic configuration.

$ su
$ apt-get install sudo
$ adduser ondrej sudo
$ sudo vi /etc/sudoers

And change this line to, that will stop requiring password for users who are in sudo group.

%sudo     ALL=(ALL:ALL) NOPASSWD:ALL

Then logout from root and your session and login again. We should see the difference when we run.

$ whoami
ondrej
$ sudo whoami
root

Lets setup static IP address to avoid changing IP every time when we start that virtual machine.

$ ip address
$ sudo vi /ect/network/interfaces

Make the file look like this.

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

allow-hotplug enp0s3
iface eth0 inet static
  address 192.168.199
  netmask 255.255.255.0
  gateway 192.168.1.1

Then.

sudo reboot --reboot

Then verify the static address is assigned.

ip address
