Announcing DoltLab: Your Self-Hosted DoltHub Solution

10 min read

Download the latest DoltLab here and head over to for the latest documentation

In recent months, we've had a number of customers reach out to us in Discord telling us they're interested in exploring Dolt for their company, but feel uncomfortable pushing their company's private data to DoltHub.

More often than not, these conversations include a request to our CEO, Tim Sehn, for an on-prem DoltHub that users can self-host and self-manage. Unfortunately, before today, we did not offer such a solution.

The original vision for DoltHub was modeled on GitHub and it was designed to be a closed-source hub for all Dolt databases. But, as we are seeing now, and especially with the popularity of GitLab, people want a DIY DoltHub option. Well, giddy-up yall 🤠!

Today, we're excited to announce the launch of our latest product: DoltLab, your self-hosted, self-managed DoltHub solution! Since demand for such a product has been steadily increasing in our Discord server, we set out to quickly ship a product users could run themselves to more deeply explore the power of Dolt for their enterprise use-cases.


Please note, this blog will only cover how to start running your own DoltLab instance and is designed to be a step-by-step guide on how to launch DoltLab on EC2. We will cover some of the more technical aspects of DoltLab and how we created it in later blog posts.

Before we begin, please be aware that this is an alpha version of our DoltLab product and more stable releases will come out in the next few months. There will be no migration option for these early releases, so to upgrade to a newer DoltLab version you'll have to kill this one and start a new one. Currently, the DoltLab code is still closed-source, but we are working to open-source it along with the code for DoltHub. But be warned, DoltLab, in its current state, is only for the bold. There are known bugs and broken pieces of core functionality that I will identify in this blog's conclusion, but it works decently enough to get you started.

If you encounter any such bugs, please feel free to file issues for them so we can triage and fix them, and come chat with us on Discord in our #doltlab channel.

Let's get started!

  8. Push Data

Installing and Running DoltLab on EC2

At the time of this blog, DoltLab's current version, v0.1.0, is only supported on Linux and its setup and operation may be a bit too complicated for some of our users. We are prioritizing improving the development and operational experience of DoltLab, but if you are undeterred by a bit of shell-fu, read on!

DoltLab, in its current form, is a collection of service images that we maintain in a publicly accessible ECR repository. To run these services together, we provide a zip folder available for download from S3.

This folder contains everything you need to run DoltLab, including a script. However, there is a bit of setup and installation we need to do first before we can start our DoltLab instance.

Provision a Linux machine

To start, you need a Linux amd64 host with specific ports open, plenty of RAM, and plenty of disk. For this walkthrough I'll use a smaller EC2 instance type, but if you want to push large databases to DoltLab, don't skimp on the machine. For this guide I chose an Ubuntu Server 18.04 AMI.

DoltLab OS Type

Here I'm using a t2.medium instance as I will only be pushing a single example database to my DoltLab instance.

DoltLab Instance Type

Next, you'll need to open four specific ports in the "Security Group" settings.

DoltLab Security Groups

22 is for connecting to the machine using ssh, 80 is for connecting to DoltLab (currently only http is supported), 100 is a port used by DoltLab for retrieving data, and 50051 is the port used to push and pull data using Dolt.

At the time of this blog, these ports are not configurable 🤠.

After launching our instance and connecting to it using ssh, it's time to install the dependencies we need to download and run DoltLab.

Install Dependencies

I've included below the exact commands I've run on this machine, in the exact order I ran them.

Install unzip and make

$ sudo apt update -y
$ sudo apt install unzip
$ sudo apt install make

Install and Configure aws cli

To download the DoltLab zip folder from ECR, you can use the aws cli. Installation instructions can be found in detail here, but here's what I ran:

$ curl "" -o ""
$ unzip
$ sudo ./aws/install

Verify the installation succeeded:

$ aws --version
aws-cli/2.4.11 Python/3.8.8 Linux/5.4.0-1060-aws exe/x86_64.ubuntu.18 prompt/off

Configure the client with your AWS credentials:

$ aws configure
AWS Secret Access Key [None]: XXXXXXXXXXXXXXXX
Default region name [None]:
Default output format [None]:

Install Docker, Docker-Compose, and Perform the Post-Install Steps

Detailed instructions for installing Docker on ubuntu can be found here. Instructions for installing Docker-Compose can be found here. I ran:

sudo apt-get update
sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli
sudo apt-get install docker-ce=5:20.10.12~3-0~ubuntu-bionic docker-ce-cli=5:20.10.12~3-0~ubuntu-bionic

Verify the installation succeeded:

docker --version
Docker version 20.10.12, build e91ed57
sudo curl -L "$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Verify the installation succeeded:

docker-compose --version
docker-compose version 1.29.2, build 5becea4c

Detailed instructions for the post-install steps (required so that Docker can be run without the sudo command) can be found here. I ran:

sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

Verify docker can run without sudo:

docker ps

Install and Configure amazon-ecr-credential-helper

Installation instructions for amazon-ecr-credential-helper can be found here. I ran:

git clone
cd amazon-ecr-credential-helper && make docker
sudo mv ./bin/local/docker-credential-ecr-login /usr/local/bin/

Verify the installation was successful:

docker-credential-ecr-login -v
Version:    0.5.0
Git commit: f15886b

Now, we can create the required config.json file:

cd ..
mkdir ~/.docker
echo '{"credHelpers":{"":"ecr-login"}}' > ~/.docker/config.json

Download and Unzip DoltLab

Now for the good stuff! It's finally time to download and run DoltLab. I ran the following two commands to download and unzip the current release of DoltLab:

aws s3 cp s3://doltlab-releases/linux/amd64/
unzip -d doltlab
  inflating: doltlab/gentokenenckey
  inflating: doltlab/docker-compose.yaml
  inflating: doltlab/envoy.yaml
  inflating: doltlab/

Inside the unzipped directory doltlab, you'll find four items. gentokenenckey is a simple binary used to generate a token encryption key that DoltLab uses to sign tokens. It will create a file called iter_token.keys during start up.

envoy.yaml is the configuration for DoltLab's proxy server, required for service-to-service communication, and docker-compose.yaml is the docker-compose configuration file used to run all of DoltLab's services in unison. is the script used to start DoltLab, and that's what we will run to start our DoltLab instance. We need to supply a couple environment variables, though, to successfully run the script and start DoltLab.

Start DoltLab

You'll need to supply four environment variables to the script: HOST_IP is the IP address or DNS address of your EC2 instance. POSTGRES_USER=dolthubadmin is the postgres user used to create and run DoltLab's PostgreSQL server.

Finally, POSTGRES_PASSWORD and DOLTHUBAPI_PASSWORD are used to set the password for the postgres server and DoltLab API database. You can choose any password for these last two environment variables.

You can now execute which will setup all the services, and run them with docker-compose in daemon mode:

HOST_IP=12.345.678.901 POSTGRES_USER=dolthubadmin POSTGRES_PASSWORD=password DOLTHUBAPI_PASSWORD=password ./

Once the script finishes, verify the services are running:

docker ps
CONTAINER ID   IMAGE                                                             COMMAND                  CREATED          STATUS          PORTS                                                                                  NAMES

Your Doltlab instance is now running. Navigate to the IP address of your machine in your browser (for example http://12.345.678.901/), and you'll see DoltLab's minimal homepage:

DoltLab Homepage

Create an Account

To start using DoltLab, click the "Sign In" button then click "Create Account", then click "Sign up with Email". New accounts created on DoltLab will be instantly verified.

DoltLab Homepage

After you've created your new account, you'll see "Welcome to DoltLab" and some instructions on how to install Dolt and authenticate your Dolt client to start pushing, pulling, and cloning DoltLab databases.

Add Dolt Credentials

Unfortunately, using a Dolt client on the same machine where DoltLab is running takes a bit of work, since DoltLab's remote API runs inside a docker network.

I recommend using your local Dolt client to connect to your DoltLab instance, but if you insist on using Dolt on the same machine, you'll need to do so by using the Dolt client inside a Docker container that is attached to the DoltLab Docker network, ie:

docker run -it --rm --network doltlab_doltlab ubuntu:18.04 /bin/bash

The above command will provide you an ubuntu:18.04 container with access to the doltlab_doltlab network, where you can connect a Dolt client to the remote host http://doltlabremoteapi:50051/[owner name]/[database name].

For now, let's keep things a bit simpler by just working with the Dolt client installed on our local computer.

To authenticate your Dolt client to use DoltLab, run the dolt creds new command, which will output a new public key:

dolt creds new
Credentials created successfully.
pub key: fef0kj7ia389i5atv8mcb31ksg9h3i6cji7aunm4jea9tccdl2cg

Copy this public key and run:

dolt creds use fef0kj7ia389i5atv8mcb31ksg9h3i6cji7aunm4jea9tccdl2cg

Finally, on DoltLab, click your Profile image, then click "Settings".

DoltLab Profile Settings

Next, click "Credentials." Add the new public key here. This will allow you to start pushing, pulling, and cloning databases.

DoltLab Add Credentials

Create a Database

Click the "Databases" link at the top of the page, then click the "Create Database" button to create your first database. For this example, let's create a copy of DoltHub's dolthub/corona-virus database.

DoltLab Create Database

Currently, DoltLab only supports public databases. Click "Create database". You've now successfully created a new database on DoltLab! As our final step, lets push the data from dolthub/corona-virus to our copy on DoltLab.

Push Data

With our local Dolt client, let's clone dolthub/corona-virus by running:

dolt clone dolthub/corona-virus

After the clone completes, cd into the corona-virus directory and run the dolt remote add command to add your DoltLab instance as a new remote:

dolt remote add doltlab http://12.345.678.901:50051/dustin/corona-virus

And lastly, run the dolt push command to push the data to your DoltLab database:

dolt push doltlab master

After the push completes, refresh the database page on DoltLab and you'll see the pushed data!

DoltLab Pushed Data


As I mentioned above, this is an alpha release of DoltLab. Currently, there's some core functionality that is broken, like, private databases are unsupported, pull request merges and forking don't really work, but we will continue fixing these issues as well as improving the DoltLab operator experience so that it's much more pleasant and ergonomic.

At this time it is also unclear how well DoltLab will scale to accommodate large databases. Be sure to provision a large enough machine for what you're attempting to do. If you have any questions, or need additional help, please don't hesitate to contact us here or on Discord.
