=== For Red Hat CodeReady Containers (CRC)
* You need to have https://docs.docker.com/get-docker/[Docker] installed and running (or connected to a Docker daemon)
+* You need to setup Docker daemon to https://docs.docker.com/registry/insecure/[trust] CRC's insecure Docker registry which is exposed by default through the route `default-route-openshift-image-registry.apps-crc.testing`. One way of doing that is to instruct the Docker daemon to trust the certificate:
+** `oc extract secret/router-ca --keys=tls.crt -n openshift-ingress-operator`: to extract the certificate
+** `sudo cp tls.crt /etc/docker/certs.d/default-route-openshift-image-registry.apps-crc.testing/ca.crt`: to copy the certificate for Docker daemon to trust
+** `docker login -u kubeadmin -p $(oc whoami -t) default-route-openshift-image-registry.apps-crc.testing`: to test that the certificate is trusted
+
* Run `make install-crc`: to build the project and install it in the current namespace on CRC
* You can specify a different namespace with `make install-crc project=myawesomeproject`
* To uninstall Camel K, run `kamel uninstall --all --olm=false`
