Customer SSH - Useful Commands

Enter a customer's application container

To enter a website container as a customer, you can either:

• Add your SSH key through developer tools in the UI and SSH to username@server_ip.
• Log in as root on the server and type:

su - customer_username

Either way, you will be within the customer's containerised PHP environment. You will have access to the exact file structure and binaries that the customer's PHP applications use, and you can monitor their PHP processes and sub-processes.

Running PHP CLI

The PHP binary is located at /usr/bin/php. This will match the version selected in the dashboard.

php script.php

For deeper debugging, you can use strace to see system calls, such as file reads or network connections:

strace php script.php

Piping Output

To send a script's output (stdout) to a file:

php script.php > script.log

To send both stdout and error logs (stderr) to a file:

php script.php > script.log 2>&1

Available Binaries

/usr/bin/composer

/usr/bin/wp-cli

/usr/bin/top

/usr/bin/rm

/usr/bin/mkdir

/usr/bin/chmod

Copying Files

You and your customers also have access to ssh and rsync binaries which are very useful for transferring websites from other servers without the risk of using root privileges.
