LXD - Linux Containers - Lightweight open source virtualisation
- #Linux
A pratical step by step example of virtualisation using Linux Containers (LXD) - https://canonical.com/lxd.
LXD with MariaDB and RabbitMQ in linux containers using Alpine
LXD install
sudo apt update
sudo apt install snapd
sudo snap install lxd
sudo snap refresh lxd
getent group lxd | grep "$USER"
sudo usermod -aG lxd "$USER"
newgrp lxd
lxd init --minimal
acessing via browser (LXD UI)

MariaDB
set and start container
lxc image list images: alpine 3.20 architecture=$(uname -m)
lxc launch images:alpine/3.20 mariadbserver # add --vm here if you want a VM instead a Container
lxc config set mariadbserver limits.memory=500MiB
lxc config set mariadbserver limits.cpu=4
lxc config device override mariadbserver root size=1GiB
lxc restart mariadbserver
lxc info mariadbserver
lxc storage list
install mariadb
lxc exec mariadbserver -- sh
apk update
apk add mariadb mariadb-common mariadb-client
rc-service mariadb setup
# rc-service mariadb start
rc-update add mariadb default
mariadb-secure-installation
add the following at the end of /etc/my.cnf.d/mariadb-server.cnf
[mysqld]
skip-networking=0
skip-bind-address
configure mariadb
lxc exec mariadbserver -- sh
mysql -u root -p
create database somedb;
create user 'user'@'%' identified by 'password';
grant all privileges on somedatabase to 'user'@'%';
lxc snapshot mariadbserver mariadbserver-init
connect to mariadb
lxc list # get the ip address of mariadbserver
mysql -h the_ip_address -u user -p
RabbitMQ
set and start container for rabbitmq
lxc launch images:alpine/3.20 rabbitmqserver # add --vm here if you want a VM instead a Container
lxc config set rabbitmqserver limits.memory=500MiB
lxc config set rabbitmqserver limits.cpu=4
lxc config device override rabbitmqserver root size=1GiB
lxc restart rabbitmqserver
lxc info rabbitmqserver
install rabbitmq
lxc exec rabbitmqserver -- sh
apk update
apk add rabbitmq-server
#rc-service rabbitmq-server start
rc-update add rabbitmq-server default
mkdir /etc/rabbitmq
touch /etc/rabbitmq/enabled_plugins
rabbitmq-plugins enable rabbitmq_management
rabbitmqctl add_user username password
rabbitmqctl set_user_tags username administrator, management
rabbitmqctl set_permissions username ".*" ".*" ".*"
lxc snapshot rabbitmqserver rabbitmqserver-init
acessing ui via browser (RabbitMQ Management UI)
lxc list # get the ip address of rabbitmqserver
