Cloudbreak is a cloud agnostic Hadoop As A Service solution. It is easy to install, only one command in the command line, and an other one to start the service itself. During startup Cloudbreak Deployer tries to figure out the underlay infrastructure and sets required environment variables with competent default values, but some cases it isn't enough. In this article i collected all of the possible customizations, default values and some hint what does the variable configure in Profile file.

By default, Cloudbreak uses a built-in PostgreSQL database to persist data. For production environments, we suggest that you use an external database, an RDS served by your cloud provider. If you choose to use the default database, you should know that Cloudbreak deployer includes features for dumping and restoring built-in databases. Cloudbreak deployer uses Docker for the underlying infrastructure and uses Docker volume for storing data. There are two separate volumes: a volume called `common` for storing live data a volume called `cbreak_dump` for database dumps You can override default live data volume any time by extending your `Profile` with the following variable: export COMMON_DB_VOL="my-live-data-volume" To create database dumps, execute the following commands: cbd db dump common cbdb cbd db dump common uaadb cbd db dump common periscopedb The dump command has an optional third parameter, the `name` of the dump. If you give your dump a name, Cloudbreak deployer will create a symbolic link which points to the SQL dump. For example: cbd db dump common cbdb name-of-the-dum To list existing dumps, execute the `cbd db list-dumps` command. Each kind of database dump (cbdb, uaadb, periscopedb) has a link to the latest dump on the `cbreak_dump` volume. During the restore process, Cloudbreak deployer restores from latest dump. To check which dump is the latest, execute: docker run --rm -v cbreak_dump:/dump -it alpine ls -lsa /dump/cbdb/latest You can set any of the existing dumps as latest with `set-dump` command. You can set both regular or named dumps. For example: cbd db set-dump cbdb 20170628_1805 or cbd db set-dump cbdb name-of-the-dump To remove the existing `common` volume, stop all the related Cloudbreak containers with `cbd kill` command, and then remove the volume: docker volume rm common To restore databases from dumps, execute: cbd db restore-volume-from-dump common cbdb cbd db restore-volume-from-dump common uaadb cbd db restore-volume-from-dump common periscopedb You can easily save your dumps to the host machine by using the following commands: docker run --rm -v cbreak_dump:/dump -it alpine cat /dump/cbdb/latest/dump.sql > cbdb.sql docker run --rm -v cbreak_dump:/dump -it alpine cat /dump/uaadb/latest/dump.sql > uaadb.sql docker run --rm -v cbreak_dump:/dump -it alpine cat /dump/periscopedb/latest/dump.sql > periscopedb.sql ...
