How to backup a Team Password Manager installation in a Docker container

In this document we're going to explain how to backup the data (database and files) of a Team Password Manager installation in Docker containers.

For reference, here's our general backup document: How to make a backup of Team Password Manager

Backing up the database

If your database runs in a Docker container, which is the case if you're using Docker Compose, execute this command from the host to make a backup copy of your Team Password Manager database:

docker exec -it mysql_container mysqldump -utpm_user -ptpm_password tpm_database > backup_file.sql

Where:

• mysql_container is the container that runs the database. You can see the running containers in your system with this command: docker ps.
• tpm_database is the Team Password Manager database.
• tpm_user and tpm_password are the credentials of the user that has access to the tpm_database.

Basically this command executes mysqldump inside the container and returns the backup_file.sql to the host.

Backing up the files

Execute this command from the host to copy the software files (including the uploads folder) into the host:

docker cp teampasswordmanager_container:/var/www/html/site/. ./backup/

Where teampasswordmanager_container is the container that runs Team Password Manager. You can see the running containers in your system with this command: docker ps.

This command copies the /var/www/html/site/ folder and its subfolders and files to the host, in the backup folder in the current folder. This copies all the software files, if you want to copy only the uploads folder, use this instead:

docker cp teampasswordmanager_container:/var/www/html/site/uploads/. ./backup/
