Installation Centos Docker-CE in VirtualBox
Because of the need to test environment, a CentosOS 7 installed.
After installation found no IP, I thought it was because NAT setup issues.
The network is set to bridging, in use ip addr or not.
After the original is because the default does not start, you need to start can.
vi / etc / sysconfig / network- scripts / ifcfg-enp0s3
modified ONBOOT = yes then systemctl restart network can obtain the IP
Then install the docker-ce
First update the system sudo yum update
Install the necessary dependencies.
