Managing LXC (Linux Container) on a single host requires a deep understanding of the Linux environment, as well as the resources that the host environment has to offer. Here’s a process to managing multiple LXC:
1. Installation – Firstly, make sure you have installed LXC on your host. You can use the command `sudo apt-get install lxc`.
1. Create the containers – Use the command `sudo lxc-create -t download -n my-container` to create a container. You can repeat this process to create multiple containers.
1. Start the containers – Use the command `sudo lxc-start -n my-container -d` to start the container. Replace `my-container` with the name of your container.
1. Manage your resources – Distribute the resources of your host machines through c-groups to manage your containers. By doing this, none of the containers would lack resources while others have an abundance.
1. Monitor the containers – `lxc-info -n my-container` can be used to get information about the state of a container.
1. Stop/Destroying the containers – You can use `sudo lxc-stop -n my-container` to stop a running container. Also, if you want to remove a container, use the command `sudo lxc-destroy -n my-container`
1. Consolidated Management with LXC Web Panel: It is a web-based administration tool to manage LXC containers. It provides functionality to create, start, stop, destroy containers and going into more advanced features like clones, snapshots.
1. Using Tools like LXD: LXD is the next generation of LXC, making it even easier to manage and interact with your containers. LXD includes a REST API, multiple-host support, advanced resource control, and more.
1. Container Networking: Use container networking to enable communication between containers on a single host or across multiple hosts.
1. Security: Use Linux kernel security features like AppArmor or Seccomp to isolate the applications running inside your containers.
Always make sure to monitor the capacity and performance of your host environment, to ensure that each LXC is functioning optimally. You can use tools such as LXCFS to have a flexible and real view of system resources. If any LXC is consuming too much resource, it can be tuned with cgroups.
Remember to balance the load of processes between LXCs to keep your server in the best possible condition.
NOTE: All the commands listed above should be run on the host machine. Make sure the host system is configured properly and has the necessary hardware requirements before proceeding with LXC container management.
