Question

这与此question有关，但稍有不同：我不需要传递'yes'或'no'，而是需要Fabric将任意字符串传递给远程shell。

例如，如果远程shell提示“你叫什么名字？”然后我需要'先，最后'喂它。

澄清：我知道我说任意输入，但我真的是trying to use it for the SSH key passwd prompt when I try to do a git pull。

更新＃1：得到Jeff Forcier @bitprophet的回复

that’s like the #1 wart right now :( Either tunnelling to send a key agent out-of-band, or remote prompting, is needed.
I meant adding support for those things in Fabric, is what we need to do to get network-borne git ops working
Adding an easy way to kick off an OOB ssh agent-friendly tunnel is going to be easier/faster, most likely. Soon probably

Answer 1

我已在邮件列表的Fabric中为此功能提出了一个API，最后自己写了一些东西：

from fexpect import expect, expecting, run 

prompts = []
prompts += expect('What is your name?','John')
prompts += expect('Where do you live?','New York')

with expecting(prompts):
    run('command')

请参阅expecting prompts in fabric with fexpect

Answer 2

Fabric 1.0最终支持与远程服务器的交互。有关详细信息，请参阅this page。

Answer 3

也许请查看pexpect

Answer 4

我已经设置了一个名为project_name / .git的git源代码库。

   ssh to the server, (entering ssh passwords or passphrases as I go)
   mkdir project_name
   cd project_name
   git init
   touch fabfile.py
   git add  fabfile.py
   git commit -a -m "almost empty"
   git checkout -b web

我将分支网络检出。回到本地机器。

我通过克隆从服务器拉出来，并在本地仓库的分支主机中添加了我的项目目录内容。虽然这些步骤也可以自动完成，但我认为这些步骤不会使用结构，而且也不需要另外的ssh密码短语。

   cd /path/to/project_name/..
   git clone ssh://joe@some_server.com/var/web/project_name/.git
   cd project_name
   gvim fabfile.py
   git add  fabfile.py
   git commit -a -m "fabfile edits"

现在我开始使用面料了。以下是我用于管理git标签的fabfile的摘录和分支机构：

  #Usage: fab committag brpush  |    fab committag push   |  fab push  | fab tag
def committag():
    """commit chgs, tag new commit, push tags to server."""
    prompt('commit descr: ', 'COM_MSG', default='new stuff')
    prompt('commit name: ', 'COM_NAME', default='0.0.1')
    local('git commit -a -m "%(COM_MSG)s"' % env)
    local('sleep 1')
    local('git tag -u "John Griessen" -m "%(COM_MSG)s" %(COM_NAME)s' % env)
    local('sleep 1')
    local('git push origin --tags') #pushes local tags

def brpush():
    """create  a new branch, default COM_NAME, then push to server."""
    prompt('new branch name: ', 'BR_NAME', default= '%(COM_NAME)s'  % env)
    local('git checkout -b %(BR_NAME)s'  % env)
    local('sleep 2')
    local('git checkout master')
    local('git push origin --tags') #pushes local tags
    local('git push --all origin')  #pushes local master and branches

def push():
    """Push existing tags and changes to server."""
    local('git push origin --tags') #pushes local tags
    local('git push --all origin')  #pushes local master and branches


def tag():   #Call this from committag()
    """create  a gpg signed tag on the local git repo tag from prompted name ."""
    prompt('tag descr: ', 'TAG_MSG', default='0.0.1')
    prompt('tag name: ', 'TAG_NAME', default='0.0.1')
    local('git tag -u "John Griessen" -m "%(TAG_MSG)s" %(TAG_NAME)s' % env)

要使用上面的fabfile defs，我只是对我的项目目录做了一些修改，想一想关于他们的适当消息，并做：

$fab committag

我在服务器上标记和更新了更改。或者：

$fab committag brpush

我创建了一个新分支并更新了服务器。

跳过主机验证提示的一种方法是：

run('ssh-keyscan github.com > ~/.ssh/known_hosts')

另外，我正在使用py-github来安装deploy keys:

run('ssh-keygen -q -t rsa -f /home/%(user)s/.ssh/id_rsa -N ""' % env)
key = run('cat /home/%(user)s/.ssh/id_rsa.pub' % env)
gh.repos.addDeployKey(repo, env.host, key)
