NAME
SVN::Notify::Mirror::SSH - Mirror a repository path via SSH
SYNOPSIS
Use svnnotify in post-commit:
svnnotify --repos-path "$1" --revision "$2" \
--handler Mirror::SSH --to "/path/to/www/htdocs" \
[--svn-binary /full/path/to/svn] \
[[--ssh-host remote_host] [--ssh-user remote_user] \
[--ssh-tunnel 10.0.0.2] \
[--ssh-identity /home/user/.ssh/id_rsa]]
or better yet, use SVN::Notify::Config for a more sophisticated setup:
#!/usr/bin/perl -MSVN::Notify::Config=$0
--- #YAML:1.0
'':
PATH: "/usr/bin:/usr/local/bin"
'path/in/repository':
handler: Mirror
to: "/path/to/www/htdocs"
'some/other/path/in/repository':
handler: Mirror::SSH
to: "/path/to/remote/www/htdocs"
ssh-host: "remote_host"
ssh-user: "remote_user"
ssh-tunnel: "10.0.0.2"
ssh-identity: "/home/user/.ssh/id_rsa"
DESCRIPTION
Keep a directory in sync with a portion of a Subversion repository. Typically used to
keep a development web server in sync with the changes made to the repository. This
directory can either be on the same box as the repository itself, or it can be remote (via
SSH connection).
USAGE
Depending on whether the target is a "Local Mirror" or a Remote Mirror, there are
different options available. All options are available either as a commandline option to
svnnotify or as a hash key in SVN::Notify::Config (see their respective documentation for
more details).
Working Copy on Mirror
Because 'svn export' is not able to be consistently updated, the sync'd directory must be
a full working copy, and if you are running Apache, you should add lines like the
following to your Apache configuration file:
# Disallow browsing of Subversion working copy
# administrative directories.
<DirectoryMatch "^/.*/\.svn/">
Order deny,allow
Deny from all
</DirectoryMatch>
The files in the working copy must be writeable (preferrably owned) by the user identity
executing the hook script (this is the user identity that is running Apache or svnserve
respectively).
Local Mirror
Please see SVN::Notify::Mirror for details.
Remote Mirror
Used for directories not located on the same machine as the repository itself. Typically,
this might be a production web server located in a DMZ, so special consideration must be
paid to security concerns. In particular, the remote mirror server may not be able to
directly access the repository box.
NOTE: be sure and consult "Remote Mirror Pre-requisites" before configuring your post-
commit hook.
• ssh-host
This value is required and must be the hostname or IP address of the remote host
(where the mirror directories reside).
• ssh-user
This value is optional and specifies the remote username that owns the working copy
mirror.
• ssh-identity
This value may be optional and should be the full path to the local identity file
being used to authenticate with the remote host. If you are setting the ssh-user to be
something other than the local user name, you will typically also have to set the ssh-
identity.
• ssh-tunnel
If the remote server does not have direct access to the repository server, it is
possible to use the tunneling capabilities of SSH to provide temporary access to the
repository. This works even if repository is located internally, and the remote
server is located outside of a firewall or on a DMZ.
The value passed for ssh-tunnel should be the IP address to which the local repository
service is bound (when using svnserve). This will tunnel port 3690 from the
repository box to localhost:3690 on the remote box. This must also be the way that
the original working copy was checked out (see below).
To tunnel some other port, for example when using Apache/mod_dav, ssh-tunnel should be
the entire mapping expression, as described in the OpenSSH documentation under the
"-R" option (remote port forwarding). For most sites, passing "8080:10.0.0.2:80" will
work (which will tunnel port 80 from the repository to port 8080 on the remote
client). If you are using SSL with Apache, you can use e.g. "80443:10.0.0.2:443".
For example, see "Remote Mirror Pre-requisites" and after step #6, perform the
following additional steps (when using svnserve):
# su - localuser
$ ssh -i .ssh/id_rsa remote_user@remote_host -R3690:10.0.0.2:3690
$ cd /path/to/mirror/working/copy
$ svn co svn://127.0.0.1/repos/path/to/files .
where 10.0.0.2 is the IP address hosting the repository service. For the same
configuration when using Apache/mod_dav, do this instead:
# su - localuser
$ ssh -i .ssh/id_rsa remote_user@remote_host -R8080:10.0.0.2:80
$ cd /path/to/mirror/working/copy
$ svn co http://127.0.0.1:8080/repos/path/to/files .
• ssh-options
If you have any other options that you would like to pass to the ssh client (for
example to change the default SSH port), you can pass extra options using this
parameter. Be sure that you pass it a string that has ssh long option/value pairs
separated by a space, or short options without any space at all. Internally,
parameter is split on spaces and passed in the @Net::SSH::options array.
Remote Mirror Pre-requisites
Before you can configure a remote mirror, you need to produce an SSH identity file to use:
1. Log in as repository user
Give the user identity being used to execute the hook scripts (the user running Apache
or svnserve) a shell and log in as that user, e.g. "su - svn";
2. Create SSH identity files on repository machine
Run "ssh-keygen" and create an identity file (without a password).
3. Log in as remote user
Perform the same steps as #1, but this time on the remote machine. This username
doesn't have to be the same as in step #1, but it must be a user with full write
access to the mirror working copy.
4. Create SSH identity files on remote machine
It is usually more efficient to go ahead and use "ssh-keygen" to create the .ssh
folder in the home directory of the remote user.
5. Copy the public key from local to remote
Copy the .ssh/id_dsa.pub (or id_rsa.pub if you created an RSA key) to the remote
server and add it to the .ssh/authorized_keys for the remote user. See the SSH
documentation for instructions on how to configure
6. Confirm configuration
As the repository user, confirm that you can successfully connect to the remote
account, e.g.:
# su - local_user
$ ssh -i .ssh/id_rsa remote_user@remote_host
This is actually a good time to either check out the working copy or to confirm that
the remote account has rights to update the working copy mirror. If the remote server
does not have direct network access to the repository server, you can use the tunnel
facility of SSH (see ssh-tunnel above) to provide access (e.g. through a firewall).
Once you have set up the various accounts, you are ready to set your options.
