Calculate Linux family has recently received one more distro - Calculate Linux Container (CLC). It is created specially to be installed in a LXC/LXD container.
Before installing it, please, update the system:
Below you can find an example of creating LXC container with setting up OpenRC using DHCP server in a local network.
Install required packages
To work with LXC containers you need the package
Install the system in the container
To install Calculate Linux Container you should run following command:
lxc-create -n calculate -t download -- --server mirror.calculate-linux.org --no-validate
nname you assign to the container
servermirror (list of available mirrors)
no-validatedon’t check gpg signature
The download scenario will show a list of available images and ask to select distro “CLC” (in capital letters), its release and architecture.
Then the program will download an image and install it. All installed containers are located in the directory
To setup a network in LXC container you need to setup a network bridge. An example of settings for OpenRC in the file
config_eth0="null" bridge_br0="eth0" config_br0="dhcp" bridge_worward_delay_br0=0 bridge_hello_time_br0=1000 bridge_stp_state_br0=0
You should also delete a symbolic link
/etc/init.d/net.eth0 and create a new one
/etc/init.d/net.eth0 stop rm -f /etc/init.d/net.eth0 ln -s /etc/init.d/net.lo /etc/init.d/net.br0 /etc/init.d/net.br0 start
Then you need to make network settings of the container in the file
# network type, veth if you use a bridge lxc.network.type = veth # startup network interface during the boot lxc.network.flags = up # interface name inside the container lxc.network.name = eth0 # bridge name for a virtual interface lxc.network.link = br0 # name of the network adaptor for this container on a host machine lxc.network.veth.pair = veth-calculate # random MAC address for the network interface of the container (first digit must be even) lxc.network.hwaddr = 02:03:04:05:06:07
Start the container
You can start the container with the following command:
lxc-start -n calculate
Open the container console:
lxc-attach -n calculate
After that you can enable a network:
/etc/init.d/net.eth0 start rc-update add net.eth0 default
To leave you can either enter ‘exit’ or press Ctrl+d.
To add the container to the autostart:
ln -sf /etc/init.d/lxc /etc/init.d/lxc.calculate rc-update add lxc.calculate default
Please, notice that the path must already exist in the system.
/home you should edit the container settings file
/var/calculate/lxc/calculate/config by adding a following string:
lxc.mount.entry = /home home none rw,bind 0.0
