Docker Swarm Code Analysis Note (1)--main.go

This is a creation in Article, where the information may have evolved or changed.

main.goThe code is as follows:

package mainimport (    _ "github.com/docker/docker/pkg/discovery/file"    _ "github.com/docker/docker/pkg/discovery/kv"    _ "github.com/docker/docker/pkg/discovery/nodes"    _ "github.com/docker/swarm/discovery/token"    "github.com/docker/swarm/cli")func main() {    cli.Run()}

The following 4 line of code guarantees that package the corresponding init function can be executed:

_ "github.com/docker/docker/pkg/discovery/file"_ "github.com/docker/docker/pkg/discovery/kv"_ "github.com/docker/docker/pkg/discovery/nodes"_ "github.com/docker/swarm/discovery/token"

Only token This package is the swarm new realization, the rest file , kv and nodes all are docker existing.

The

CLI package uses GITHUB.COM/CODEGANGSTA/CLI this project to build the CLI program. Instead, the CLI. The run () function executes swarm specific command ( create , manage , and so on).
