Re: Post Commit Hook Script !!

Well the interactive part has been removed. Moreover, there exists null keys between the servers so it won't prompt for password. The current issue that I'm facing is that it gives the following error on execution
Warning: post-commit hook failed (exit code 255) with output:+ /usr/bin/ssh -l root 'cd /deploy/Project/config; /usr/bin/cap deploy:php tagid=Code1'Host key verification failed.
The deployment script has an environment variable set which takes the tagid as specified in the command line. The set is as follow
From my machine I do commit, the changes are updated in the repository on svn server. The hook script gets invoked and connects to another server where deployments scripts are available and the script in turn connects to different destination servers. The entire process uses SSH and I am using null keys for the time being.

I modified the script as given below. Only changes I have done is removed IF loops and it works fine. The permissions are the same.

Your original script showed you using absolute paths to head, cut, awk, which is what you should be doing because the hook script runs with an empty environment and who knows what the $PATH is.

ssh? How will the authentication occur? Obviously if it prompts you for a password there's no way to respond to that prompt. So you'd need ssh keys. Make sure they're in the correct directory for the user that this hook script is running under.
