+# Prometheus image
+
+Command for run:
+```
+docker run -d --name="prometheus" -p 9090:9090 -v promdata:/var/lib/prometheus IMAGENAME
+```
+
+*If you want to be able to view services on localhost, instead of -p, specify the flag:
+```
+--network="host"
+```
+Prometheus will see all the services running on your local hosting, without this it will not be able to access your ports
+
+
+To upload your own configuration, create prometheus.yml, you can use example from:
+```
+https://raw.githubusercontent.com/prometheus/prometheus/main/documentation/examples/prometheus.yml
+```
+Then, while the container is running, enter its command:
+```
+docker cp $PWD/prometheus.yml prometheus:/etc/prometheus/prometheus.yml
+
+docker restart prometheus
+```
