 ## [1.29.2]
 
 This release improve TeslaMate behavior on Tesla API rate limits, which occur from time to time. We respect the retry-after header on 429 response code to not hammer the API unnecessarily in these cases.

-title: Web based management of your docker installation
----
-
-To manage your docker installation of TeslaMate you could use the open-source management UI [portainer](https://portainer.io).
-
-## Installation
-
-Add a new `portainer` service and a `portainer-data` volume to your `docker-compose.yml`:
-
-```yml docker-compose.yml {4-12,15}
-services:
-  portainer:
-    image: portainer/portainer
-    restart: always
-    ports:
-      - 9000:9000
-    command: -H unix:///var/run/docker.sock
-    volumes:
-      - /var/run/docker.sock:/var/run/docker.sock
-      - portainer-data:/data
-
-volumes:
-  portainer-data:
-```
-
-Afterwards, access the docker management console at http://yourhost:9000.
-
-:::caution
-Exposing the docker socket (`docker.sock`) is a security risk. Giving an application access to it is equivalent to giving a unrestricted root access to your host. For more information see [OWASP: Do not expose the Docker daemon socket](https://cheatsheetseries.owasp.org/cheatsheets/Docker_Security_Cheat_Sheet.html#rule-1---do-not-expose-the-docker-daemon-socket-even-to-the-containers).
