Container
The container is a basic tool, refers to any tool can accommodate other items.
Linux Namespaces (docker container technology is mainly achieved by isolation 6)
| namespace | System call arguments | Isolate content | Kernel version |
| UTS | CLONE_NEWUTS | Host and domain name | 2.6.19 |
| IPC | CLONE_NEWIPC | Information, message queues and shared memory | 2.6.19 |
| PID | CLONE_NEWPID | Process number | 2.6.24 |
| Network | CLONE_NEWNET | Network equipment, network stack, ports, etc. |
2.6.29 |
| Mount | CLONE_NEWNS | Mount point (file system) | 2.4.19 |
| User | COLNE_NEWUSER | Users and user groups | 3.8 |
Control Groups, CGroups control group (typically used to restrict the use of resources) the system-level resources into a plurality of groups, and the amount of resources within each group is assigned or allocated to a different user-space process.
blkio: IO block device
cpu: CPU
cpuacct: CPU resource usage reports
cpuset: a collection of multi-processing CPU on the platform
devices: Device Access
freezer: suspend or resume the task
memory: Memory Usage Report
perf_event: task group from the unified performance test
net_ds: data cgroup tasks created packet class identifier
A tool LXC (LinuX Container) first to achieve art container (container belongs to a technical linux kernel)
When the container is created using lxc-create, it will not activate the template to allow you to install, but is connected to the server to download the template match you wear a mirror, so the mirror onto the local and container-based image to boot. When a user to control a container used.
docker LXC is actually an enhanced version of a management tool, but docker is based mirroring to achieve, and LXC is based on a template to achieve.
Scheduling tool
compose: single arrangement
machine + swarm + compose a cluster arrangement
mesos + marathhon
kubernetes
