Setup and Installation

There are multiple way to bring up ModelDB.

Docker Setup

Deploy pre published images

If you have Docker Compose installed, you can bring up a ModelDB server with just a single command.

docker-compose -f docker-compose-all.yaml up

This command will fetch the published images from Docker hub and setup the multi container environment. The webapp can be accessed at http://localhost:3000.

Logs will have an entry similar to Backend server started listening on 8085 to indicate backend is up. During the first run backend will have to run the liquibase scripts so it will take a few extra minutes to come up. The progress can be monitored in the logs.

Once the command finishes it might take a couple of minutes for the proxy, backend and frontend to establish connection. During this time any access through frontend or client may result in 502.

Build images from source and deploy

To build the images you need Docker and jdk(1.8) installed. Each of the modules has a script to build its Docker image. This flow can be triggered by running from the root of the repository

./build_all_no_deploy_modeldb.sh

This will build the Docker images locally.

To use these images run steps in Deploy pre published images, but this time since there will be locally built images , those will be used instead of pulling the images from remote repository.

A utility script to combine the two steps is available and can be run as

./build_modeldb.sh

Kubernetes Setup

Helm chart is available at chart/modeldb. ModelDB can be brought up on a Kubernetes cluster by running:

cd chart/modeldb
helm install . --name <release-name> --namespace <k8s namespace>

By default, the default namespace on your Kubernetes cluster is used. release-name is a arbitrary identifier user picks to perform future helm operations on the cluster.

To bring a cluster down, run:

helm del --purge <release-name-used-install-cmd>

AWS ami

An pre-baked ami modeldb-ubuntu-18.04-amd64-minikube-1.14.9-oss-1585711178 with modeldb running on minikube is made available on AWS. You can launch a EC2 machine with the image to spin up a deployment of ModelDB, accessible at http://< public hostname or ip >: 30080. You will be required to open the port 30080 to access modeldb via client or browser.
