+before usage, we have to configure insecure registry usage in dockerd (https://docs.docker.com/registry/insecure/)
+
+we have to check default deamon config file path:
+
+```bash
+dockerd --help | grep config-file
+```
+
+it should be:
+
+```bash
+--config-file string                      Daemon configuration file (default "/etc/docker/daemon.json")
+```
+
+open ```etc/docker/deamon.json``` file (If the daemon.json file does not exist, create it.) and append these lines:
+
+```json
+{
+  "insecure-registries" : ["http://0.0.0.0:5050"]
