Functions

func GetSigner

func GetSigner(provider string) (ssh.Signer, error)

    GetSigner returns an ssh.Signer for the provider ("gce", etc.) that can be used to SSH to their nodes.

    func IssueSSHCommand

    func IssueSSHCommand(cmd, provider string, node *v1.Node) error

      IssueSSHCommand tries to execute a SSH command

      func LogResult

      func LogResult(result Result)

        LogResult records result log

        func NodeSSHHosts

        func NodeSSHHosts(c clientset.Interface) ([]string, error)

          NodeSSHHosts returns SSH-able host names for all schedulable nodes. If it can't find any external IPs, it falls back to looking for internal IPs. If it can't find an internal IP for every node it returns an error, though it still returns all hosts that it found in that case.

          Types

          type Result

          type Result struct {
          	User   string
          	Host   string
          	Cmd    string
          	Stdout string
          	Stderr string
          	Code   int
          }

            Result holds the execution result of SSH command

            func IssueSSHCommandWithResult

            func IssueSSHCommandWithResult(cmd, provider string, node *v1.Node) (*Result, error)

              IssueSSHCommandWithResult tries to execute a SSH command and returns the execution result

              func NodeExec

              func NodeExec(nodeName, cmd, provider string) (Result, error)

                NodeExec execs the given cmd on node via SSH. Note that the nodeName is an sshable name, eg: the name returned by framework.GetMasterHost(). This is also not guaranteed to work across cloud providers since it involves ssh.

                func SSH

                func SSH(cmd, host, provider string) (Result, error)

                  SSH synchronously SSHs to a node running on provider and runs cmd. If there is no error performing the SSH, the stdout, stderr, and exit code are returned.
