Add a scp command

[mietek]

It would be great to be easily able to scp files to droplets.

Good idea, or even rsync! 👍

FWIW, here's my current workaround:

function tug () {
    local info
    info=`tugboat info "$1"` || return 1
    awk '/IP:/ { print $2 }' <<<"${info}"
}

function tugpath () {
    case "$1" in
    *:*)
        local ip
        ip=`tug "${1%:*}"` || return 1
        echo "root@${ip}:${1#*:}"
        ;;
    *)
        echo "$1"
    esac
}

function tugscp () {
    local from to
    from=`tugpath "$1"` || return 1
    to=`tugpath "$2"` || return 1
    scp "${from}" "${to}"
}

Goes well with a somewhat lenient ssh config, shown here with what is presumably the London data centre IP range:

Host 178.62.*
  LogLevel quiet
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null

Works both for uploads and downloads:

$ touch baz
$ tugscp baz foobar:
baz                                           100%    0     0.0KB/s   00:00 

$ rm baz
$ tugscp foobar:baz .
baz                                           100%    0     0.0KB/s   00:00

@petems: You may find e.g. Ubuntu 10.04 LTS doesn't ship with rsync:

$ rsync baz `tugpath oldbar:baz`
bash: rsync: command not found
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at /SourceCache/rsync/rsync-42/rsync/io.c(452) [sender=2.6.9]

Nevertheless, a native rsync command would be great, too:

$ rsync -v baz `tugpath foobar:baz`
baz

sent 80 bytes  received 42 bytes  81.33 bytes/sec
total size is 0  speedup is 0.00

BTW I would opt for not using Ubuntu 10.04 LTS anymore ...

My wrapper looks like this:

#!/bin/bash

function tug-remove-ssh-config(){
  local NAME=$1
  if test -z "$NAME"; then echo "no name given"; return 1; fi

  sed "\|# ${NAME}|,+3 d" ~/.ssh/config-digitalocean
}

function tug-add-ssh-config(){
  local NAME=$1
  local IP=$2

  if test -z "$NAME"; then echo "no name given"; return 1; fi
  if test -z "$IP";   then echo "no ip given";   return 1; fi

  # if you add lines here, remember to remove them in tug-tug-remove-ssh-config()
cat <<EOF > ~/.ssh/config-digitalocean
# $NAME $(date)
Host $NAME
  HostName $IP
  User root

EOF
}

function tug-create(){
  local NAME=$1
  if test -z "$NAME"; then echo "no name given"; return 1; fi

  tugboat create $NAME -i SOMEID -r 10 -k SOMESSHKEY
  tugboat wait $NAME

  local IP=$(tugboat info $NAME | awk '/IP:/ { print $2  }')

  tug-remove-ssh-config $NAME
  tug-add-ssh-config $NAME $IP
}

alias tug-ssh="ssh -F ~/.ssh/config-digitalocean"
alias tug-scp="scp -F ~/.ssh/config-digitalocean"

The benefit of aliasing ssh instead of using tugboat ssh is that I can open tunnels etc. just as with the native ssh command… because it is the native ssh command. ;)

The drawback is it only works for droplets created by the script a.t.m..

This probably the next big feature I want to work on, I might have some free time over the christmas period so hopefully I'll be able to give it some time over December! 👍

[petems]

Only took over 3 years but initial minimal version of the feature has been added here! #291
