+# assisted-service runs on minikube
+
+## Debug Setup
+
+To debug assisted-service directly from minikube container
+Install minikube setup with assisted-service
+
+```shell
+export KUBECONFIG=source /root/.kube/config
+kubectl patch deployment assisted-service -n assisted-installer --type json -p="[{\"op\": \"remove\", \"path\": \"/spec/template/spec/containers/0/livenessProbe\"}]"
+oc rollout restart deployment -n assisted-installer assisted-service
+```
+
+Login to minikube node and attach to assisted-service container
+
+```shell
+ssh -l docker [ip_address]   # password is tcuser  
+docker exec -it --user root [assisted_id]  /bin/bash
+# install packages git goland and telnet
+dnf install procps psmisc golang delve iproute iputils telnet net-tools  -y
+```
+
+Before running dlv attach make sure assisted-service sources exists 
+
+```shell
+git clone https://github.com/openshift/assisted-service.git
+# git checkout to the same minikube assisted-service version/tag
+```
+Note! Before attaching to golan binary you should know in case you break/debug 
+in line the assisted-service pod goes down. in order to start pod again run continue
+When we break in a line or function we can trigger the event from UI cluster or other tools
+
+```shell
+dlv attach 1
