I tried to use bash script provided by Passbolt: Create A Backup of Passbolt Data With A Bash Script

I’m hosting Passbolt community myself using Docker. When running the script I get this message:

±-----------------------------------------------------------------------------------------+
| You don’t have the webserver_user set in the backup.sh file |
| Please correct this and then re-run this script |
±-----------------------------------------------------------------------------------------+

Why does this happen? The article suggest this script can be run outside the docker container. I also tried running the script inside the docker container, but get the message mysql-server is not installed.

Hey, @daankennes welcome to the forum!

For this you need to open the script with an editor and then on lines 3-4 there are instructions

#! /bin/bash

# Be sure to set this variable to what your webserver user is. Typically it will be www-data or nginx
# webserver_user=

So in the end you’d likely want this set to:

#! /bin/bash

# Be sure to set this variable to what your webserver user is. Typically it will be www-data or nginx
webserver_user=www-data

Hi Clayton, thank you!

In the article, it seems to be implied that you should not have to edit that line when using Docker. Is that wrong?

I edited the backup script, but I now get this output:

So a couple misunderstandings here, I didn’t initially realize you were trying to run this on the host machine where you have a docker container running. That isn’t supported with this script. It needs to be either on the server where passbolt is running via a package installation or in the docker container itself

As for running it in the container it is correct that you’ll get the error about not having mysql/mariadb installed since we don’t bundle that in the passbolt docker image by default. To run this script you’ll have to install it so you can access the mysqldump command which this relies on
