Initial .env config breaks when passwords contain certain special characters

[introini]

In the initial run of the docker-compose.yml, the .env file breaks when setting a password that contains special characters such as & ' /.

Pop!_OS 18.10

docker-compose up -d

The resulting .env file (www/.env) contains the following variables:

DB_HOST=bookstack_db
DB_DATABASE=bookstackapp
DB_USERNAME=bookstack
DB_PASSWORD=exampleDB_PASSWORD=database_user_passwordpassword

Not sure how the fields in the docker-compose.yml are parsed, but escaping these characters could be a solution. Another solution could be to mention the limitation and advise users to use only alphanumeric passwords.

Thanks, team linuxserver.io

Have you tried wrapping the password in single quotes?

If that fixes it, then I would expect that the variable needs to be quoted whenever it's getting parsed on container startup...

We use sed to take ENV variables and write them into the Env file.
We are not doing anything special to escape special characters and for the functionality this provides I do not believe we will be.

I know it is not what you want to hear, but please manually configure the file after the fact if you are running into this.
