Back-up and restore

Why do you need this?

There are several reasons when you need to use back-up and restore.

1. You need to migrate your DB from the container to the stand-alone version (which is a must for production with big amount of tests).
2. You care about your data and do not want to lose the data.

Backups and restoration of data from backups

How to make the backup of the database for docker-compose deployment

Before you start the backup process or restore process, please stop all the containers which do not have -db_ in their names.

Allure TestOps databases backup

docker exec -t [CONTAINER_WITH_DB] pg_dump -c -U [POSTGRESQL_USER] > [prefix-]backup.sql

where

• CONTAINER_WITH_DB is the name of a container running the database.

• POSTGRESQL_USER is the Postgres DB user name, you will find it in .env file

[prefix-] is the prefix for the file with DB dump, it is worth go name the files something like **uaa-**backup.sql and so on.

Restore a database

If you are started the containers using docker-compose, you need to stop the containers without the databases as described in the prerequisites section.

Drop the existing (presumably empty) database

docker exec -it [POSTGRESQL_CONTAINER] psql -U [POSTGRESQL_USER] -d postgres -c "DROP DATABASE [POSTGRESQL_DATABASE]"

• POSTGRESQL_DATABASE is either report or uaa

Create empty database

docker exec -it [POSTGRESQL_CONTAINER] psql -U [POSTGRESQL_USER] -d postgres -c "CREATE DATABASE [POSTGRESQL_DATABASE]"

• POSTGRESQL_DATABASE is either report or uaa

Restore from previously made backup

cat backup.sql | docker exec -i [POSTGRESQL_CONTAINER] psql -U [POSTGRESQL_USER] -d [POSTGRESQL_DATABASE]

• POSTGRESQL_DATABASE is either report or uaa

How to make the backup of the database for Kubernetes deployment

Allure TestOps databases backup

1. Stop all Allure TestOPs pods except the DB ones.
2. Create the DB dump as follows:

kubectl exec [pod-name] -- bash -c "pg_dump -U [postgres-user] [database-name]" > database.sql

where

• pod-name is the name of the Postgres pod.
• postgres-user is the database user that is able to access the database.
• database-name is the name of the database.

Allure TestOps databases restoration

cat database.sql | kubectl exec -i [pod-name] -- psql -U [postgres-user] -d [database-name]
