Configuration

Add Cytomine registry to MicroK8s

After installing the Cytomine, you will have to set up a configuration file to allow MicroK8s to communicate with the private registry.

1. Get the IP address of the registry container, using

   sudo docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' cytomine-registry-1
   

2. Create the directory and configuration file:

   • mkdir -p /var/snap/microk8s/current/args/certs.d/<registry-ip>:5000
   • touch /var/snap/microk8s/current/args/certs.d/<registry-ip>:5000/hosts.toml

   Where <registry-ip> is the output of step 1.

   Normally, sudo privileges are not required.

3. Add the following lines inside the hosts.toml file:

   server = "http://<registry-ip>:5000"
   [host."http://<registry-ip>:5000"]
   capabilities = ["pull", "resolve"]
   

4. Restart MicroK8s to have the new configuration loaded:

   microk8s stop
   

   microk8s start
   

More information are available at the How to work with a private registry (opens new window) section of the official documentation of MicroK8s.

MicroK8s is now ready for use by Cytomine, you can proceed with the installation.
