Documentation

All the documentation for the MINT framework can be found in the MINT documentation page.

Testing on local machine

To test the MINT services on your local machine, we strongly recommend using the microk8s Kubernetes distribution. Follow the instructions in the microk8s documentation to install microk8s on your machine.

Microk8s installation

Tested on MacOS (arm64) and microk8s 1.28/stable. Tested on Ubuntu 22.04 (amd64) and microk8s 1.28/stable.

Install the microk8s using the following command:

$ microk8s install --memory 8
Support for 'multipass' needs to be set up. Would you like to do that now? [y/N]: y

Enable required addons:

$ microk8s enable dns
$ microk8s enable dashboard
$ microk8s enable hostpath-storage
$ microk8s enable ingress

To test, list the existing resources. It should be list multiple services, deployments, and pods. Please wait until all the resources are up and running.

$ microk8s kubectl get all --all-namespaces

Verify the node status

$ microk8s kubectl get nodes

MINT services installation

Use the following commands to install the MINT services:

$ microk8s helm repo add mint https://mintproject.github.io/mint
$ microk8s helm repo update
$ microk8s helm install testing-mint mint/MINT --namespace mint --create-namespace

If you using MacOS Silicon, you need to install the arm64 version of the postgresql database.

WARNING: The arm64 image has not been tested and may not work as expected. Please use it at your own risk.

$ microk8s helm repo add mint https://mintproject.github.io/mint
$ microk8s helm repo update
$ microk8s helm install testing-mint mint/mint --namespace mint --create-namespace --set arm_support=true

Helm will returns the URL to access the MINT services. You can use the following command to get the URL:

The MINT system has been installed!

Please remember to edit your `/etc/hosts/`

After that, you can access to the MINT services

http://mint.local
http://ensemble-manager.mint.local
http://cromo.mint.local
http://mic.mint.local
http://datacatalog.mint.local

If you are using microk8s on a VM, need to get the IP address of the VM to access the MINT services. You can use the following command to get the IP address of the VM:

$ microk8s kubectl get node -o json | jq '.items[].status.addresses[] | select(.type=="InternalIP") | .address'
10.211.59.16

Then, edit the /etc/hosts file and add the following lines:

$ sudo vim /etc/hosts

Add the following lines (replace the IP address with the IP address of the VM):

10.211.59.16 mint.local
10.211.59.16 cromo.mint.local
10.211.59.16 mic.mint.local
10.211.59.16 api.mic.mint.local
10.211.59.16 datacatalog.mint.local
10.211.59.16 endpoint.models.mint.local
10.211.59.16 graphql.mint.local
10.211.59.16 models.mint.local
10.211.59.16 api.models.mint.local
10.211.59.16 endpoint.models.mint.local

MINT services removal

To remove the MINT services, use the following command:

$ helm uninstall mint -n mint
$ kubectl delete pvc --all  -n mint
$ kubectl delete jobs --all -n mint

or

bash uninstall.sh
