- The URL hostname for the MinIO Server.
The MinIO Console by default uses the local hostname (i.e. ``$HOSTNAME``)
as the address for the MinIO server. You may need to set this variable
in the following scenarios:
- The URL hostname the MinIO Console uses for connecting to the MinIO
Server. The hostname *must* be resolveable and reachable for the
Console to function correctly.
- The MinIO server TLS certificates do not cover the local hostname
(i.e. in IP or DNS :abbr:`SAN (Subject Alternative Name)`) such that
the Console cannot validate the TLS certificates.
Specify a hostname contained in the TLS certificate to allow the MinIO
The MinIO Console connects to the MinIO Server using an IP
address by default. For example, when the MinIO Server starts up,
the server logs include a line
``API: https://<IP ADDRESS 1> https://<IP ADDRESS 2>``.
The MinIO Console defaults to connecting using ``<IP ADDRESS 1>``.
The MinIO Console may require setting this variable in the following
scenarios:
- The MinIO server TLS certificates do not include the local IP address

Static vs Dynamic Port Assignment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MinIO by default selects a random port for the MinIO Console on each server
startup. Browser clients accessing the MinIO Server are automatically
redirected to the MinIO Console on its dynamically selected port.
This behavior emulates the legacy web browser behavior while reducing the
the risk of a port collision on systems which were running MinIO *before* the
embedded Console update.
You can select an explicit static port by passing the
:mc-cmd-option:`minio server console-address` commandline option when starting
each MinIO Server in the deployment.
For example, the following command starts a distributed MinIO deployment using
a static port assignment of ``9001`` for the MinIO Console. This deployment
would respond to S3 API operations on the default MinIO server port ``:9000``
and browser access on the MinIO Console port ``:9001``.
.. code-block:: shell
:class: copyable
minio server https://minio-{1...4}.example.net/mnt/disk-{1...4} \
--console-address ":9001"
Deployments behind network routing components which require static ports for
routing rules may require setting a static MinIO Console port. For example,
load balancers, reverse proxies, or Kubernetes ingress may by default block
or exhibit unexpected behavior with the the dynamic redirection behavior.
