Machina

Machina is an SDK for running remote commands in VM. This could be used for orchestrating installations, remote code execution over ssh etc. Consider it like ansible but with SDK and golang.

SSH into a machines

node := machina.NewNode(username, ip, privateKeyLocation)

err := node.SSHClient().Run(instructions)
if err != nil { 
  log.Fatal(err)
}

SSH with timeout

node := machina.NewNode(username, ip, privateKeyLocation)

err := node.SSHClientWithTimeout(2*time.Minutes).Run(instructions)
if err != nil { 
  log.Fatal(err)
}

Collect the output of instruction

node := machina.NewNode(username, ip, privateKeyLocation)

err := node.SSHClientWithTimeout(2*time.Minutes).Collect("cat /tmp/file")
if err != nil { 
  log.Fatal(err)
}

Determine OS of the machines

node := machina.NewNode(username, ip, privateKeyLocation)

osType, err := node.DetermineOS()
if err != nil { 
  log.Fatal(err)
}

log.Println(osType)

Running commands in parallel

node := machina.NewNode(username, ip, privateKeyLocation)

err := node.SSHClient().RunParallel([]string{"rm /tmp/file", "touch /tmp/example"})
if err != nil { 
  log.Fatal(err)
}

Creating node groups and running tasks in parallel across the nodes

	node1 := machina.NewNode("username", "ip", "key")
	node2 := machina.NewNode("username", "ip", "key")
	node3 := machina.NewNode("username", "ip", "key")

	nodeGroupManager := nodegroup.NewNodeGroup(node1, node2, node3)

	err := nodeGroupManager.Run("sudo apt-get install postgres")
	if err != nil {
		log.Fatal(err)
	}

Roadmap

• Creating orchectration for installing popular software that involves complex orchestrations
• Possible examples for docker, mariadb installation etc.
