Here is how to do web development using the very fast Ubuntu native LXC/LXD containers. Part of the Practical Ubuntu Linux Server for beginners course.
First lets install lxd in our system:
sudo snap install lxd
Then initialize the basic environment:
sudo lxd init
We will also fetch image from a repository: linuxcontainers.org
and will start a container based on it:
sudo lxc launch images:alpine/3.10/amd64 webdevelopment
Let's see what we have in the system:
sudo lxc ls
sudo lxc storage ls
sudo lxc network ls
Now it is time to access the container with: sudo lxc exec webdevelopment sh
and then we will use apk to install openssh
apk add openssh-server
lets' also add unprivileged user in order to access the ssh:
adduser webdev
we will also start the server:
service sshd start
Ok let's check with: ip a the address of the container.
Now we exit the shell(sh) and we can connect to the container using our new user: ssh webdev@ip address of container
Alright, now go back inside the container and will add the Apache service:
apk add apache2
service apache2 restart
Optional:
If we need to get rid of the container we need to stop it first:
sudo lxc stop demo
sudo lxc delete demo
If we need to get rid of the created storage pool, we run the following:
printf 'config: {}\ndevices: {}' | lxc profile edit default
lxc storage delete default
If we need to remove the created network bridge we can run:
sudo lxc network delete lxdbr0
Congratulations and happy learning !
