Problems with fabric deployment

Question

Im using the fab script from here . fab deploy throws an error at right after creating the application. The error is:

Fatal error: Low level socket error connecting to host username.webfactional.com: Connection refused (tried 1 time)

Underlying exception:
    Connection refused

I have seen this answer , but I have ssh running on my machine.

Answer 1

The root cause of the issue ended up being use of port within the code.

The bug report is here , and the fix is here

Answer 2

I had a similar connection problem with recently started EC2 instances from AWS. Apparently, the instances may not yet be accessible via ssh even though their status has switched to running already.

There seems to be no proper solution, this is the most elegant I got:

while True:
    try:
        run('whoami')
        break
    except Exception, e:
        print "instance not yet reachable, wait a little bit", e
        time.sleep(10)

Answer 3

通过降级到Fabric 1.3.4而不是1.4来解决问题
