short question: according to the changelog at

so far only 6.5.0-beta was released as docker container - is this correct?

When will the docker container for 6.6.1 be available?

Thanks for a short reply.


@agerhard Every new release of Grafana pushes a new docker image. Please have a look at and you should see that 6.6.1 is available there. We only update the docker hub changelog when there have been actual changes made to the docker image. Will have a look and see if we can make this more clear in the docker hub readme.

Hello Marcus,

thanks for pointing me in the right direction.

Checking the link yesterday at first did not help me, but today after typing the 6.6.1 into the tag field the release is visible.
