Installing Calculate into a container
To install Calculate Linux Container, run:
lxc-create -n ccs -t download -- --server mirror.calculate-linux.org --no-validate --arch x86_64 Downloading the image index WARNING: Running without gpg validation! --- DIST RELEASE ARCH VARIANT BUILD --- CCS 18 x86_64 default 20181224 --- Distribution: CCS Release: 18 Downloading the image index Downloading the rootfs Downloading the metadata The image cache is now ready Unpacking the rootfs --- You just created a Gentoo container (release=18, arch=amd64, variant=default) To enable sshd, run: rc-update add sshd For security reason, container images ship without user accounts and without a root password. Use lxc-attach or chroot directly into the rootfs to set a root password or create user accounts.
css with any other suitable container name. The boot script will display the available images and prompt you for the distribution name in capitals ( CCS~ ) and the release number (currently 18). The application will automatically fetch the container on the cloud and install it. The installed containers are stored in the directory.
In further descriptions used in commands and paths, use the container name you have chosen instead of
Network configuration of the host computer
To configure the network in a LXC container, you will need to configure the network bridge on the host. To do this, select one of the two configuration options:
- If the host computer has multiple IP addresses, for example, if you intend to use the container on a desktop running in the local network and obtaining its IP via DHCP, you can configure the network by [using shared network] (network#ispolzovanie_obshchei_seti).
- If the host computer has a single IP address, say when starting a container on a VPS or on a dedicated server, you can configure [NAT] (network#transliatsiia_ip-adresov) with the same interface.
Network configuration of the container
Configure the network for your container:
# network type if bridge is used lxc.net.0.type = veth # start the network at system start lxc.net.0.flags = up # interface inside the container lxc.net.0.name = eth0 # bridge to be used by the virtual interface lxc.net.0.link = br0 # random MAC for the network interface of the container (first number must be even) lxc.net.0.hwaddr = 02:03:04:05:06:07
Replace the MAC (
02:03:04:05:06:07). Note that the first number must be even.
Start the container
To start the container, run:
Make sure the container is up and running:
Name: ccs State: RUNNING PID: 25107 CPU use: 3.03 seconds BlkIO use: 51.98 MiB Memory use: 61.21 MiB KMem use: 4.39 MiB Link: vethXLWII2 TX bytes: 516 bytes RX bytes: 516 bytes Total bytes: 1.01 KiB
Add the container to autostart:
ln -sf /etc/init.d/lxc /etc/init.d/lxc.ccs
rc-update add lxc.ccs
In order for the system in the container to start correctly once the network is up, create a file containing the following rule:
Configuring system in the container
You can adjust the container settings on the host computer using the
lxc-attach <container_name> -- <command> syntax, or connect to the container and run the following:
Network configuration when using a shared network
If you are using a shared network (with local IPs), you can configure the network either with DHCP or by specifying an available IP address and a router IP address.
When using a DHCP server on a local network, you simply have to run the following:
rc-update add net.eth0
Network configuration when using NAT
If using [network address translation (NAT)] (network#transliatsiia_ip-adresov), edit the host settings accordingly:
cl-setup-network --iface eth0:192.168.11.2:24 --route default:192.168.11.1 --dns 188.8.131.52
rc-update add net.eth0
In the example, the container uses IP ~192.168.11.2~~ to route via ~192.168.11.1~.
Check the localization parameters and set the password:
cl-setup-locale -l ru_RU --timezone Europe/Moscow
You can also specify the complete hostname:
cl-setup-network --hostname ccs.mydomain.org
To check the new hostname, run:
Adding applications in a container
Update Portage in the container:
At first startup, cl-update will fetch the Portage tree as well as all added overlays.
Now install the software you need for logging and cron jobs:
emerge -a syslog-ng logrotate vixie-cron
When you have completed the configuration, exit the container:
