Use this library to do remote testing of vagrant nodes.
For example, this will select the "mynode" node and run "ls" on it.
vagrant := &Vagrant{}
vagrant.Setup(false, "", 3) // 3 node cluster, do not run `vagrant up`.
out, err := vagrant.GetNode("mynode").RunCommandWithOutput("ls")
if err != nil {
// exit status != 0
panic(err)
}
fmt.Println(out) // already a stringSimilarly for a Baremetal node:
hosts := []HostInfo{
{
Name: "self",
SSHAddr: "127.0.0.1",
SSHPort: "22",
User: "vagrant",
PrivKeyFile: "/vagrant/testdata/insecure_private_key",
},
{
Name: "self1",
SSHAddr: "127.0.0.1",
SSHPort: "22",
User: "vagrant",
PrivKeyFile: "/vagrant/testdata/insecure_private_key",
},
}
bm := &Baremetal{}
c.Assert(bm.Setup(hosts), IsNil)
out, err := bm.GetNode("mynode").RunCommandWithOutput("ls")
if err != nil {
// exit status != 0
panic(err)
}
fmt.Println(out) // already a stringIf you want to walk nodes, you have a few options:
Sequentially:
vagrant := &remotessh.Vagrant{}
vagrant.Setup(false, "", 3)
for _, node := range vagrant.GetNodes() {
node.RunCommand("something")
}In Parallel:
vagrant := &remotessh.Vagrant{}
vagrant.Setup(false, "", 3)
err := vagrant.IterateNodes(func (node remotessh.TestbedNode) error {
return node.RunCommand("docker ps -aq | xargs docker rm")
})
if err != nil {
// one or more nodes failed
panic(err)
