and can&#x27;t credibly support <strong>high availability</strong> as a result, we do not support nor recommend
using our <code>docker-compose</code> constructs to support production-type use-cases. For single host
environments, we recommend using <a href="https://minikube.sigs.k8s.io/docs/start/" target="_blank" rel="noopener noreferrer">minikube</a> along
our <a href="https://superset.apache.org/docs/installation/running-on-kubernetes" target="_blank" rel="noopener noreferrer">installing on k8s</a>
documentation.</p></div></div><p>Note that there are 3 major ways we support to run docker-compose:</p><ol><li><strong>docker-compose.yml:</strong> for interactive development, where we mount your local folder with the
frontend/backend files that you can edit and experience the changes you
make in the app in real time</li><li><strong>docker-compose-non-dev.yml</strong> where we just build a more immutable image based on the
local branch and get all the required images running. Changes in the local branch
at the time you fire this up will be reflected, but changes to the code
while <code>up</code> won&#x27;t be reflected in the app</li><li><strong>docker-compose-image-tag.yml</strong> where we fetch an image from docker-hub say for the
<code>3.0.0</code> release for instance, and fire it up so you can try it. Here what&#x27;s in
the local branch has no effects on what&#x27;s running, we just fetch and run
pre-built images from docker-hub</li></ol><p>More on these two approaches after setting up the requirements for either.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="requirements">Requirements<a href="#requirements" class="hash-link" aria-label="Direct link to Requirements" title="Direct link to Requirements">​</a></h3><p>Note that this documentation assumes that you have <a href="https://www.docker.com" target="_blank" rel="noopener noreferrer">Docker</a>,

to <code>docker compose up</code> even though in some cases you may want to force a check for newer remote
images using <code>docker compose pull</code>, force a build with <code>docker compose build</code> or force a build
on latest base images using <code>docker compose build --pull</code>. In most cases though, the simple
<code>up</code> command should do just fine.

Also note that <code>docker/.env-local</code> is referenced in our <code>.gitignore</code>,
preventing developers from risking committing potentially sensitive configuration to the repository.</p><p>One important variable is <code>SUPERSET_LOAD_EXAMPLES</code> which determines whether the <code>superset_init</code>
container will populate example data and visualizations into the metadata database. These examples
are helpful for learning and testing out Superset but unnecessary for experienced users and
production deployments. The loading process can sometimes take a few minutes and a good amount of
CPU, so you may want to disable it on a resource-constrained device.</p><p>For more advanced or dynamic configurations that are typically managed in a <code>superset_config.py</code> file
located in your <code>PYTHONPATH</code>, note that it can be done by providing a
<code>docker/pythonpath_dev/superset_config_docker.py</code> that will be ignored by git
(preventing you to commit/push your local configuration back to the repository).
The mechanics of this are in <code>docker/pythonpath_dev/superset_config.py</code> where you can see
that the logic runs a <code>from superset_config_docker import *</code></p><div class="theme-admonition theme-admonition-note alert alert--secondary admonition_LlT9"><div class="admonitionHeading_tbUL"><span class="admonitionIcon_kALy"><svg viewBox="0 0 14 16"><path fill-rule="evenodd" d="M6.3 5.69a.942.942 0 0 1-.28-.7c0-.28.09-.52.28-.7.19-.18.42-.28.7-.28.28 0 .52.09.7.28.18.19.28.42.28.7 0 .28-.09.52-.28.7a1 1 0 0 1-.7.3c-.28 0-.52-.11-.7-.3zM8 7.99c-.02-.25-.11-.48-.31-.69-.2-.19-.42-.3-.69-.31H6c-.27.02-.48.13-.69.31-.2.2-.3.44-.31.69h1v3c.02.27.11.5.31.69.2.2.42.31.69.31h1c.27 0 .48-.11.69-.31.2-.19.3-.42.31-.69H8V7.98v.01zM7 2.3c-3.14 0-5.7 2.54-5.7 5.68 0 3.14 2.56 5.7 5.7 5.7s5.7-2.55 5.7-5.7c0-3.15-2.56-5.69-5.7-5.69v.01zM7 .98c3.86 0 7 3.14 7 7s-3.14 7-7 7-7-3.12-7-7 3.14-7 7-7z"></path></svg></span>note</div><div class="admonitionContent_S0QG"><p>Users often want to connect to other databases from Superset.

Connecting Superset to your local database instance" title="Direct link to 4. Connecting Superset to your local database instance">​</a></h3><p>When running Superset using <code>docker</code> or <code>docker compose</code> it runs in its own docker container, as if
the Superset was running in a separate machine entirely. Therefore attempts to connect to your local
database with the hostname <code>localhost</code> won&#x27;t work as <code>localhost</code> refers to the docker container
Superset is running in, and not your actual host machine. Fortunately, docker provides an easy way
to access network resources in the host machine from inside a container, and we will leverage this
capability to connect to our local database instance.</p><p>Here the instructions are for connecting to postgresql (which is running on your host machine) from
Superset (which is running in its docker container). Other databases may have slightly different
configurations but gist would be same and boils down to 2 steps -</p><ol><li><strong>(Mac users may skip this step)</strong> Configuring the local postgresql/database instance to accept
public incoming connections. By default, postgresql only allows incoming connections from
<code>localhost</code> and under Docker, unless you use <code>--network=host</code>, <code>localhost</code> will refer to different
endpoints on the host machine and in a docker container respectively. Allowing postgresql to accept
connections from the Docker involves making one-line changes to the files <code>postgresql.conf</code> and
<code>pg_hba.conf</code>; you can find helpful links tailored to your OS / PG version on the web easily for
this task. For Docker it suffices to only whitelist IPs <code>172.0.0.0/8</code> instead of <code>*</code>, but in any
case you are <em>warned</em> that doing this in a production database <em>may</em> have disastrous consequences as
you are opening your database to the public internet.  2. Instead of <code>localhost</code>, try using
<code>host.docker.internal</code> (Mac users, Ubuntu) or <code>172.18.0.1</code> (Linux users) as the hostname when
attempting to connect to the database. This is a Docker internal detail -- what is happening is
that, in Mac systems, Docker Desktop creates a dns entry for the hostname <code>host.docker.internal</code>
which resolves to the correct address for the host machine, whereas in Linux this is not the case
(at least by default). If neither of these 2 hostnames work then you may want to find the exact
hostname you want to use, for that you can do <code>ifconfig</code> or <code>ip addr show</code> and look at the IP
address of <code>docker0</code> interface that must have been created by Docker for you. Alternately if you
don&#x27;t even see the <code>docker0</code> interface try (if needed with sudo) <code>docker network inspect bridge</code> and
