Slow symlink upload
Symlinks can be uploaded from the command line by running scp
in recursive mode:
bashscp -r
$
However, enabling the mode will also copy the content to which the symlink is pointing to. This is troublesome if we only want the symlinks to be copied, and it’s not possible to do it differently with SCP.
This is usually solved by using rsync:
bashrsync -avz -e ssh /scr-dir user@host:/dst-dir
$
Unfortunately, rsync is very time-consuming.
Solution 1: Local Script + Server Upload + Host Script
The first solution employs some simple scripts alongside the deployment action. First we need a script grab-links.sh
that will list all symlinks in the folder. The script will search the folder in recursive mode and create a file create-links.sh
with instructions that will reproduce the symlinks on the target server:
bash# !/bin/sh echo "#!/bin/sh\n" > create-links.sh for file in $(find . -type l); do link=$(readlink $file); echo "if [ ! -L $file ]; then ln -s $link $file; fi" >> create-links.sh; done
$$$$$$$
Now, we need to save the script to the grab-links.sh
file and execute:
bashchmod +x grab-links.sh ./grab-links.sh
$$
This will generate create-links.sh
that you can upload and run on the target server to reproduce your symlinks:
bashchmod +x create-links.sh ./create-links.sh
$$
Automation
In Buddy, you can create a pipeline that will automatically perform all these steps on every push to the repository. Here's what you need to do:
- Upload the script
grab-links.sh
to the repository. - Add a new pipeline and set the trigger mode to run on every push.
- Add a Local Shell action and enter the commands that will run the script in the Buddy’s infrastructure:
bashchmod +x grab-links.sh ./grab-links.sh
$$
- Add an SFTP action that will upload the newly generated script
create-links.sh
. - Add an SSH action and enter these commands to run the script on the target server:
bashchmod +x create-links.sh ./create-links.sh
$$

Solution 2: Git Clone
Git handles symlinks exactly the way one could expect: if you push a symlink to the repository and somebody else clones this repository, the symlink will be reproduced in their local repo. So, basically, all that you need to do is install Git on the production server and run
bashgit clone
$
Automation
With Buddy you can execute git clone
automatically on every push the repository. A good practice is to add unit tests to make sure your code is free of errors before it’s pulled.
- Add a new pipeline and set the trigger mode to run on every push.
- Add a Local Shell action.
- Add an SSH action that will execute
git clone
on the external repository.
