期望脚本在单独调用时有效，但不能作为盐状态 [英] expect script works while invoking individually but not as a salt state

问题描述

我正在尝试通过期望做scp以及ssh.如果我像/usr/bin/expect myexpect.sh这样直接从终端调用它，则下面的脚本有效，但是当我使用salt运行它时，第一个scp命令在第二个ssh失败的地方起作用.

I'm trying to do scp as well as ssh through expect. Below script works if I invoke it directly from terminal like /usr/bin/expect myexpect.sh but when I ran it using salt, the first scp command works where the second ssh fails.

myexpect.sh

#!/usr/bin/expect -f

set timeout 240

spawn scp apps.tar.gz /srv/salt/integration/serverclass_merged.conf foo@10.10.10.10:/home/foo
expect "password:"
send "password\n";
expect eof

spawn ssh -o StrictHostKeyChecking=no foo@10.10.10.10 "cd /home/foo;tar --strip-components=1 -xzvf apps.tar.gz -C /opt/apps/;cp serverclass_merged.conf /opt/local/serverclass.conf"
expect "assword:"
send "password\r"
interact

相关的盐状态看起来像

st.sls

copy_apps:
  cmd.run:
    - name: /usr/bin/expect /home/ocdn_adm/myexpect.sh

推荐答案

我对盐堆，但我怀疑它没有从pty运行您的Expect脚本.因此，将interact替换为expect eof(或在必要时使用expect -timeout 12345 eof). interact仅在stdin位于tty/pty上时有效.

I know nothing about salt-stack but I suspect it's not running your Expect script from a pty. So replace interact with expect eof (or expect -timeout 12345 eof if necessary). interact works only when stdin is on a tty/pty.
