What LXC can do:You can bind specific CPUs and memory to a container, assign a specific percentage of CPU time, IO time, limit the amount of memory that can be used (including memory and swap space), provide device access control, and provide an independent namespace (network, PID, IPC, MNT, UTS).The default LXC configuration is to isolate PIDs (process) SysV IPC (interprocess communication), and mount points. If you want to run sshd, you must provide a new network stack and hostname, and if you
How is Linux composed?A: Linux is made up of user space and kernel spaceWhy divide user space and kernel space?A: For CPU architectures, each processor can have multiple modes, and Linux is a partition that takes into account the system'sSecurity, such as X86 can have 4 mode
What is 1.LXC?LXC is the acronym for Linux containers and is a container-based virtualization technology for operating system tiers.What can 2.LXC do?LXC a virtual execution environment that can be provided for a process at the operating system level, a virtual execution environment is a container. You can bind a specific CPU and memory node to a container, allocate a specific percentage of CPU time, IO tim

files can restrict access or bandwidth, and reading values from these pseudo files provides I/O operation information
Blkio.weightSpecifies the relative proportion (weighted) of the Cgroup default available access block I/O, ranging from 100 to 1000. This value can be overridden by the Blkio.weight_device parameter of the specific device. This value is similar to Cpu.share and works in the form of a proportional access time. The default root group value is 1000. If you create two group below t
Use Docker to manage Linux iner containers in Ubuntu
Currently, Full Hardware virtualization technology (KVM, Xen, Hyper-V, etc.) can run multiple independent operating systems on a physical host, but this also brings about some problems: poor performance, waste of resources, and slow system response. Sometimes, Full Hardware virtualization is not the best choice for users.
One alternative is to use lightwe
Ctop: a command line artifact that monitors the performance of Linux containers
Ctop is a new command line-based tool that can be used to monitor processes at the container level. By using the resource management function of the controller group (cgroup), containers provide a virtual environment at the operating system level. The tool collects data related to mem
