create folder in remote server using bitbucket branch name via pipeline - linux

Question

I am developing a Laravel project and I want to have CI with it. I am using bitbucket pipelines to do this. and I am using a ubuntu VPS.I would like to have separate folders for release-branchname.
for example, if I create a branch release-1.0.0 in bitbucket, and when i am trying to deploy it should create a folder in my remote server projectname/releases/release-1.0.0. I tried many ways but I was not successful.
here is my pipeline script
release-*:
- step:
name: Preparing pipeline for release
script:
- echo 'Preparing pipeline for releases'
- step:
name: Deploing release branches
trigger: manual
deployment: test
script:
- cat ./deploy.sh | ssh root#X.X.X.X
and here is my deploy.sh
echo 'Deployment started'
cd /home/core-cms/project-root
mkdir /home/core-cms/$BITBUCKET_BRANCH
git stash
git pull origin master
composer install
echo 'Deploy finished'
exit;
if I could pass $BITBUCKET_BRANCH variable into this deploy.sh, it would work perfectly I guess.
maybe I am totally wrong and there is another way to accomplish this. if so can anyone guide me, please? Thank you.

There are two different things that you are attempting to do:
Get name of the branch from the commit and pass it to the next step
default:
- step:
deployment: test
script:
- ssh user#host "bash -s" -- < ./deploy.sh $BITBUCKET_BRANCH
Get the branch name in your scrip and do the rest
BITBUCKET_BRANCH=${1}
echo 'Deployment started'
cd /home/core-cms/
git clone -b $BITBUCKET_BRANCH user#repository.com
composer install
echo 'Deploy finished'
exit;
Here is what I have done in the code in steps:
The $BITBUCKET_BRANCH is an standard Bitbucket variable. Be aware that this var is not available using custom or tag trigers.
In the pipeline code call the script on local machine pass the branch name to it and execute it on ssh server. The code ssh user#host "bash -s" -- < will run the rest of the code as if it is running it as a local code. Adding -- will stop the remote bash to take rest of the arguments for itself.
By adding the $BITBUCKET_BRANCH after the script file name, we pass it to the script.
In the script we get the input argument using $1 and assign it to $BITBUCKET_BRANCH variable.
The code will clone the code in the sub-directory. Here you might
need some changes to avoid git conflicts.
P.S. Just to mention, I haven't test the code. It might have some misspellings. However, the solution is there. You might be able to alter it to what you'd like to do.
