Yum List Docker-ce--showduplicates | Sort-r

3. Compile Dockerd compile dockerd, you need to install many packages. You can install the required packages based on the error message. For example, I'm fedora25. Go build will report libdevmapper.h missing. Then DNF install Device-mapper-devel.x86_6.

A Docker image is a read-only template.For example, an image can contain a complete CentOS operating system environment where only httpd or other applications are installed.
Images can be used to create
containers. What specific work does Docker do after running this command? Specific as follows:
docker runCommand initialization.
Docker runs Lxc-start to execute the Run command.
Lxc-start creates a set of namespace and control Groups in the container.
options:
host1:docker_opts= "-b=br0–fixed-cidr= ' 10.211.55.64/26 '"
host2:docker_opts= "-b=br1–fixed-cidr= ' 10.211.55.128/26 '" Here, the bridge name used to specify the container connection
–fixed-cidr used to qualify the range of IP addresses assigned to a container
