# sshpool
Connection pool for x/crypto/ssh connections
API docs: https://pkg.go.dev/github.com/desops/sshpool
This is a connection pooler for golang.org/x/crypto/ssh. It's good for making hundreds (or thousands) of SSH connections to do a lot of things on a lot of hosts.
The pool itself has no configuration apart from a ClientConfig:
```go
package main
import (
"fmt"
"io/ioutil"
"os"
"github.com/desops/sshpool"
"golang.org/x/crypto/ssh"
)
func main() {
if err := run(); err != nil {
fmt.Fprintln(os.Stderr, err)
os.Exit(1)
}
}
func run() error {
buf, err := ioutil.ReadFile("./keys/my_private_ssh_key")
if err != nil {
return err
}
key, err := ssh.ParsePrivateKey(buf)
if err != nil {
return err
}
config := &ssh.ClientConfig{
User: "myuser",
Auth: []ssh.AuthMethod{
ssh.PublicKeys(key),
},
}
pool := sshpool.New(config, nil)
for i := 0; i < 100; i++ {
go func() {
err := func() error {
session, err := pool.Get("myhost")
if err != nil {
return err
}
defer session.Put() // important: this returns it to the pool
session.Stdout = os.Stdout
session.Stderr = os.Stderr
if err := session.Run("sleep 10"); err != nil {
ee, ok := err.(*ssh.ExitError)
if ok {
return fmt.Errorf("remote command exit status %d", ee.ExitStatus())
}
return err
}
return nil
}
if err != nil {
fmt.Fprintln(os.Stderr, err)
}
}()
}
return nil
}
```
