Centos+bond+bridge+docker (SSH container) Fixed IP Implementation test Environment (III)

Docker installation

Before installing, make sure that the VG has the remaining space left for Docker to do Thinpooldev, as if it were about 60% of the space left.

# yum-y Install Docker bridge-utils

Shut down the firewall and SELinux before you start

#systemctl Disable FIREWALLD

#systemctl Stop Firewalld

#setenforce 0

#sed-i ' s/selinux=enforcing/selinux=disabled/g '/etc/selinux/config

Note The SELinux configuration file locations for CENTOS6 and CENTOS7 are not the same.

Modify the Docker configuration file

Cat/etc/sysconfig/docker-network

#/etc/sysconfig/docker-network

docker_network_options="-B bridge0"

Docker detects that the VG has the remaining space to do the automatic creation of thinpooldev settings.

# Systemctl Start Docker

Cat/etc/sysconfig/docker-storage

Docker_storage_options=--storage-driver devicemapper--storage-opt dm.fs=xfs--storage-opt dm.thinpooldev=/dev/ Mapper/centos-docker--pool--storage-opt dm.use_deferred_removal=true--storage-opt Dm.basesize=20G

I added the red part myself. The default images is 10G, I increase to 20G, modify the completion remember to restart Docker.

The Docker installation is now complete.
