### Setting default user and password
If you wish to change the default username and password of `guest` / `guest`, you can do so with the `RABBITMQ_DEFAULT_USER` and `RABBITMQ_DEFAULT_PASS` environmental variables. These variables were available previously in the docker-specific entrypoint shell script but are now available in RabbitMQ directly.
```console
$ docker run -d --hostname my-rabbit --name some-rabbit -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password %%IMAGE%%:3-management
```
You can then go to `http://localhost:8080` or `http://host-ip:8080` in a browser and use `user`/`password` to gain access to the management console
### Setting default vhost
If you wish to change the default vhost, you can do so with the `RABBITMQ_DEFAULT_VHOST` environmental variables:
```console
$ docker run -d --hostname my-rabbit --name some-rabbit -e RABBITMQ_DEFAULT_VHOST=my_vhost %%IMAGE%%:3-management
```
### Memory Limits ### Memory Limits
RabbitMQ contains functionality which explicitly tracks and manages memory usage, and thus needs to be made aware of cgroup-imposed limits (e.g. [`docker run --memory=..`](https://docs.docker.com/config/containers/resource_constraints/#limit-a-containers-access-to-memory)).
