Data source: Custom

info

As the first step, you need to set up a machine for Database Lab Engine instance. See the guide Set up a machine for the Database Lab Engine.

Configuration

With this data source type you can use any PostgreSQL backup tool (e.g. pg_basebackup, Barman, pgBackRest) to transfer the data to the Database Lab Engine instance.

Jobs

To set up it you need to use following jobs:

Options

Copy the contents of configuration example config.example.physical_generic.yml from the Database Lab repository to ~/.dblab/server.yml. For demo purposes we've made example based on pg_basebackup tool, but you can use any tool suitable for the task. Check and update the following options:

  • Set secure server:verificationToken, it will be used to authorize API requests to the Engine
  • Set connection options in physicalRestore:options:envs, based on your tool
  • Set PostgreSQL commands in physicalRestore:options:customTool:
    • command: defines the command to restore data using a custom tool
    • restore_command: defines the PostgreSQL restore_command configuration option to refresh data
  • Set a proper version in Postgres Docker images tags (change the images itself only if you know what are you doing):
    • provision:options:dockerImage
    • retrieval:spec:physicalRestore:options:dockerImage
    • retrieval:spec:physicalSnapshot:options:promotion:dockerImage

Run Database Lab Engine

sudo docker run \
--name dblab_server \
--label dblab_control \
--privileged \
--publish 2345:2345 \
--volume /var/run/docker.sock:/var/run/docker.sock \
--volume /var/lib/dblab:/var/lib/dblab/:rshared \
--volume ~/.dblab/server.yml:/home/dblab/configs/config.yml \
--env DOCKER_API_VERSION=1.39 \
--detach \
--restart on-failure \
postgresai/dblab-server:2.1-latest

Restart in the case of failure
