Run SCP From Command Line With Password
python,command-line,centos,fabric,scp
First, elaborating on the security hazards of doing this, it's very easy to view command line arguments just by running ps -ww -fp <pid>. This vulnerability is why scp doesn't allow the password to be passed in on the command line. So make sure that you're okay with the fact...
fabric: run() hangs without any errors
I'm not sure what your end goal is with this code snippet. If you're trying to isolate the effects of modifying env by having it in a class, that's not going to work. It's a module level global in fabric and no matter where you modify it (by assignment like...
executing standalone fabric script by calling it by its name, without the .py extension
EDIT: Original answer corrected The fabric.main.main() function automatically adds .py to the end of supplied fabfile locations (see https://github.com/fabric/fabric/blob/master/fabric/main.py#L93). Unfortunately that function also uses Python's import machinery to load the file so it has to look like a module or package. Without reimplementing much of the fabric.main module I don't...

I want change directory and run command in fabric
As per the official tutorial, the error specifies that you have not specified a connection in your fabfile for it to deploy. Please check here. Other than that, in the cd method(used along side the with statement), use full path like with cd('/path/to/directory/myApp') rather than just the 'myApp'. Even if...

directory size of a linux machine using python fabric
This isn't a syntax error, rather the python code is still being executed on your machine and not the remote machine. So calling os.path.getsize is checking the path size on your local machine (where it does not exist). Instead you need to use fabric to execute shell commands on the...
Fabric execute with SSH key?
python,python-2.7,ssh,fabric,python-2.x
Your solution is correct, use execute to run task programmatically. The error TypeError: hostname() takes no arguments (1 given) means your function does not accept argument, which is my_env. Just modify to: def hostname(my_env): return run('hostname') And it will work....

So, I found the solution to my question. It was just a stupid thing not to check my pem file, which was secured with a passphrase. The python file can be named anything, as far as it has an execute method - and it is executed just like a normal...

Alex from Fabric here. To use different Twitter API keys or API keys generated on apps.twitter.com, you're declaring it correctly in your code above.

Python Fabric - Remove files matching a pattern in a directory w/ spaces?
Found a solution, edited in the answer to the question above as 'EDIT 2' I didn't realize there was a cd context manager in Fabric, so using that I found a solution: from fabric.api import cd with cd('/myfolder/name with spaces/files/'): sudo('rm -f *.pyc') I also discovered a separate issue: using...
How to configure fabric with SSH key on a Window machine

There are two ways to do this: Set env.hosts at the module level, so it gets set when the fabfile is imported Chain modules to set the env variable. In your case, the second one can be accomplished by removing the line prod() from collectstatic and instead invoking fabric like...
How to open another tab in command line and proceed there with fabric?
Not sure what you mean by "another tab" but I think you get stuck because python waits for the process to complete which is in the infinite loop. You need to detach the process from python after starting it. If I want Firefox to open another page in a separate...
Wait until process in remote server finishes using Fabric
python,server,wait,fabric,remote-server
One way to do this is to change the way you're calling remote_function, and use Fabric execute instead. from fabric.api import execute local_function_1() execute(remote_function) local_function_2() execute should block until the tasks complete. For more info, see Intelligently executing tasks with execute....
Fabric on Oracle Linux 6.5 fails with “pkg_resources.DistributionNotFound: paramiko>=1.10”

It looks like your fabric settings are correct with the use of variables. I was able to use the code you provided to connect to my Ubuntu VM. I am wondering if you are having a connection issue due to the amazon Instance not being fully booted and ready for...
Fabric task dependencies
I managed to do this with the runs_once decorator and execute function. The build task is now decorated with runs_once and every task that depends on build, e.g. deploy, will do execute(build) at the beginning. This will execute the build task or silently fail if it was already executed (thanks...
How to exit a supervisor process with fabric file?

How to initiate SSH connection from within a Fabric run command

In Fabric, how can I execute tasks from another python file?
Change execute('start') to execute(start). I didn't find out why pass a taskname to execute did not work, but there is a workaround: import fabfile execute(getattr(fabfile, 'start')) Update： After reading a bit code and doing some test of fabric, I think execute('task_name') can only be used when fabric tasks are loaded....

Can I have multiple Python fabfiles in one project directory?
I have learned that a single fab file is enough for a project. Instead, it is best to have a single fab file that defines multiple functions that each make use of a different server. Fabric documentation offers a few ways to do this, depending on the specific needs of...

Fabric sudo() not respecting env.password
Oh, my mistake. I had foolishly set env.sudo_user to my deploy user testuser, thinking that it was specifying the invoking user on remote. In fact, it was specifying the target user, and I was attempting to sudo into myself. Whoops.
Can fabric run a local script on a remote machine?
