I looked at the documentation found here: [http://docs.graylog.org/en/2.3/pages/upgrade/graylog-2.3.html](http://docs.graylog.org/en/2.3/pages/upgrade/graylog-2.3.html) But it just looks like things I should know but not the actual procedure. What am I missing? Where on this page does it actually say how to do the upgrade or is there another place I should look? Thanks! ---

Please refer to [http://docs.graylog.org/en/2.3/pages/installation/docker.html](http://docs.graylog.org/en/2.3/pages/installation/docker.html) Upgrades of Docker-based installations typically only require reading (and acting upon) the [Graylog upgrade notes](http://docs.graylog.org/en/2.3/pages/upgrade.html) and pulling and starting the new Docker image. ---

> [@GPConnect](#): > > should i add the plugin to the new graylog image tag everytime i do an upgrad ? Yes, otherwise the image won’t include the plugin.
