Using BitBucket Pipelines to Deploy onto VPS via SSH Access

Question

I have been trying to wrap my head around how to utilise BitBucket's Pipelines to auto-deploy my (Laravel) application onto a Vultr Server instance.

I have the following steps I do manually, which I am trying to replicate autonomously:

• I commit my changes and push to BitBucket repo
• I log into my server using Terminal: ssh root@ipaddress
• I cd to the correct directory: cd /var/www/html/app/
• I then pull from my BitBucket repo: git pull origin master
• I then run some commands: composer install, php artisan migrate etc..
• I then log out: exit

My understanding is that you can use Pipelines to automatise this, is this true?

So far, I have set up a SSH key pair for pipelines and my server, so my server's authorized_keys file contains the public key from BitBucket Pipelines.

My pipelines file bitbucket-pipelines.yml is as follows:

image: atlassian/default-image:latest  pipelines:   default:     - step:         deployment: staging         caches:           - composer         script:           - ssh root@ipaddress           - cd /var/www/html/app/           - git pull origin master           - php artisan down           - composer install --no-dev --prefer-dist           - php artisan cache:clear           - php artisan config:cache           - php artisan route:cache           - php artisan migrate           - php artisan up           - echo 'Deploy finished.' 

When the pipeline executes, I get the error: bash: cd: /var/www/html/app/: No such file or directory.

I read that each script step is run in it's own container.

Each step in your pipeline will start a separate Docker container to run the commands configured in the script

The error I get makes sense if it's not executing cd /var/www/html/app within the VPS after logging into it using SSH.

Could someone guide me into the correct direction?

Thanks

The commands you are defining under script are going to be run into a Docker container and not on your VPS.

Instead, put all your commands in a bash file on your server.

1 - Create a bash file pull.sh on your VPS, to do all your deployment tasks

#/var/www/html php artisan down git pull origin master composer install --no-dev --prefer-dist php artisan cache:clear php artisan config:cache php artisan route:cache php artisan migrate php artisan up echo 'Deploy finished.' 

2 - Create a script deploy.sh in your repository, like so

echo "Deploy script started" cd /var/www/html sh pull.sh echo "Deploy script finished execution" 

3 - Finally update your bitbucket-pipelines.yml file

image: atlassian/default-image:latest  pipelines:   default:     - step:         deployment: staging         script:           - cat ./deploy.sh | ssh <user>@<host>           - echo "Deploy step finished" 

I would recommend to already have your repo cloned on your VPS in /var/www/html and test your pull.sh file manually first.
