DBLab Engine v3.4.0

New name: DBLab Engine

The new name for the Database Lab Engine is "DBLab Engine". Updates are currently underway across our materials to reflect this change. To align with this change, we have introduced specific domains for the product:dblab.dev anddblab.sh. For ease of access, we have established the following short URLs:

By the numbers

Thank you for the support!

New DBLab SE installer

We've expanded the installation options for DBLab SE. Besides its presence inthe AWS Marketplace, you can now seamlessly install DBLab SE directly fromthe Postgres.ai Console.

This setup is entirely automated and can be used anywhere:

  • For those who have existing machines, we support the "BYOM" (Bring Your Own Machine) method
  • If you're utilizing AWS, GCP, DigitalOcean, or Hetzner Cloud, the installer handles resource provisioning—including VMs, disks, and more—automatically.

Check outthe updated tutorial.

Migration notes

For those considering an upgrade, we recommend executing a fresh installation of DBLab. At present, we don't have automation in place for upgrades. If you need to update an existing DBLab installation, it's essential to stop and remove the current containers. Then, initiate a fresh start of the DBLab container using the3.4.0 tag. More details can be found inthe docs. Before initiation, ensure you've adjusted the DBLab configuration as outlined below.

Postgres images

There is a new method for running clones with customized port and socket directories. Please note that this is NOT backward compatible with previous versions of the Postgres images that DBLab utilized. It is crucial to ensure thedockerImage options utilize tags with the-0.3.0 suffix or later, such aspostgresai/extended-postgres:15-0.3.0 (details can be found inthis MR).

Global telemetry

Theglobal.telemetry subsection has been deprecated and removed. The control to activate/deactivate telemetry has been relocated to theplatform section:

platform:url:"https://postgres.ai/api/general"enableTelemetry:true

Platform

From versionv3.4.0 onward, theplatform section is enabled by default.

If either theaccessToken ororgKey keys aren't empty, ensure theurl parameter is specified; otherwise, the DBLab instance will not initialize. By default, neitheraccessToken nororgKey are defined when in case of self-managed installations.

platform:url:"https://postgres.ai/api/general"enableTelemetry:true#  orgKey: "org_key"#  accessToken: "platform_access_token"

Docker mounts

Please omit the following Docker mount directives during container startup, as they are no longer necessary:

    --volume /sys/kernel/debug:/sys/kernel/debug:rw \    --volume /lib/modules:/lib/modules:ro \    --volume /proc:/host_proc:ro \

Database Lab Engine v3.2.0

19 Oct 17:51
Compare
Choose a tag to compare
Loading

Release v3.2.0 delivers a good number of new features and improvements. DLE UI is extended with two new tabs, "Logs" and "Configuration", to improve the user experience when configuring or reconfiguring DLE for managed Postgres services such as AWS RDS and Google Cloud SQL:

This allows users to see PGDATA initialization errors when setting up DLE, then adjust the configuration and retry initialization right in the UI – without any need to connect to the DLE machine using SSH.

The demo DLE instance can be found here:https://demo.aws.postgres.ai:446/instance (token:demo_token).

Postgres 15 is already supported!

PostgreSQL 15 is already supported by DLE and included in the list of default images, with many extensions shipped with it:https://postgres.ai/docs/database-lab/supported-databases.

AWS Marketplace – the easiest way to get DLE for any Postgres database

DLE in AWS Marketplace has now General Availability (GA) status, it has already been updated to version 3.2.0:https://aws.amazon.com/marketplace/pp/prodview-wlmm2satykuec, offering the Standard license, with support, embedded monitoring, simplified installation, and access to a wider variety of supported Postgres images (including extensions not available by default). An instance with DLE delivers "dev/test databases as a service" and levels up all dev&test processes. For example, on an r5.xlarge instance (4 vCPUs, 32 GiB RAM) with 200 GiB disk space, it is possible to run up to 30 database clones simultaneously (and even more, ifshared_buffers is adjusted to lower values) spending as low as $360 per month – less than for a single regular RDS clone of the same size.

Migration from DLE v3.1.x and configuration notes

There are no special actions that are required to migrate from DLE 3.1.x to 3.2.0: you need to stop the DLE container, change the image, and start a new one using the new image. All snapshots should remain available, and if, at stopping time, some clones were present, they should be automatically recreated by DLE.

Note: if you have an older version, check the previous release notes as well:https://gitlab.com/postgres-ai/database-lab/-/releases.

Configuration directory

The config directory, by default, is~/.dblab/engine/configs and the corresponding mounted volume must be writable:

  ...  --volume~/.dblab/engine/configs:/home/dblab/configs  ...

Logs directory

Make sure that~/.dblab/engine/logs is mounted as a volume to the DLE container:

  ...  --volume~/.dblab/engine/configs:/home/dblab/configs \  --volume~/.dblab/engine/meta:/home/dblab/meta \  --volume~/.dblab/engine/logs:/home/dblab/logs \  ...

Alternatively, you can mount the entire directory (includingconfigs andmeta – but make sure that these subdirectories exist, DLE doesn't create themyet):

  ...  --volume~/.dblab/engin...

Community news

TheREADME.md has been significantly improved. It now has four translations, with more coming in the future. Many thanks to our README translation contributors! It helps engineers worldwide understand DLE concepts and improve the development experience by building powerful dev&test environments.

Migration notes

⚠️ Prior to version 3.1, the default ZFS version DLE's Docker images were using was 0.8.x. For DLE 3.1, the default Docker image (postgresai/dblab-server:3.1.0) uses ZFS 2.1.2. If you need to upgrade DLE from a previous version that worked with a ZFS pool 0.8.x (default for previous DLE versions), consider the following options:

  • Option 1: upgrade your system to use ZFS 2.1, optionally upgrade your pool (zpool upgrade dblab_pool), and then upgrade DLE to use the default imagepostgresai/dblab-server:3.1.0
  • Option 2: postpone the ZFS upgrade, stay on ZFS 0.8, and upgrade DLE to version 3.1 using a special image,postgresai/dblab-server:3.1.0-zfs0.8

DLE 3.0.3 is a backward-compatibility update to ensure that the DLE image is compatible with existing datasets (ZFS 0.8.*). In DLE 3.0.2, in the Docker image ZFS version was prematurely switched to 2.*. The release 3.0.3 mitigates it. There are plans to switch to ZFS 2.* in the future major versions of DLE.

The development team asks everyone to participate in testing and report any bugs or improvement ideas in the DLE repository on GitLab or GitHub:

Migration notes

Make sure the DLE running command contains the environment variable--env DOCKER_API_VERSION="1.41".
The maximum supported Docker API version is 1.41, but the client version (1.42) is too new.
