link to Installing Superset Locally Using Docker Compose" title="Direct link to Installing Superset Locally Using Docker Compose"></a></h2><p>The fastest way to try Superset locally is using Docker and Docker Compose on a Linux or Mac OSX
computer. Superset does not have official support for Windows, so we have provided a VM workaround
below.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="1-install-a-docker-engine-and-docker-compose">1.

engine and a recent version of <code>docker compose</code> out of the box.</p><p>Once you have Docker for Mac installed, open up the preferences pane for Docker, go to the
&quot;Resources&quot; section and increase the allocated memory to 6GB. With only the 2GB of RAM allocated by
default, Superset will fail to start.</p><p><strong>Linux</strong></p><p><a href="https://docs.docker.com/engine/install/" target="_blank" rel="noopener noreferrer">Install Docker on Linux</a> by following Docker’s
instructions for whichever flavor of Linux suits you. Because <code>docker compose</code> is not installed as
part of the base Docker installation on Linux, once you have a working engine, follow the
<a href="https://docs.docker.com/compose/install/" target="_blank" rel="noopener noreferrer">docker compose installation instructions</a> for Linux.</p><p><strong>Windows</strong></p><p>Superset is not officially supported on Windows unfortunately. One option for Windows users to
try out Superset locally is to install an Ubuntu Desktop VM via
<a href="https://www.virtualbox.org/" target="_blank" rel="noopener noreferrer">VirtualBox</a> and proceed with the Docker on Linux instructions inside
of that VM. We recommend assigning at least 8GB of RAM to the virtual machine as well as
provisioning a hard drive of at least 40GB, so that there will be enough space for both the OS and
all of the required dependencies. Docker Desktop <a href="https://docs.docker.com/docker-for-windows/wsl/" target="_blank" rel="noopener noreferrer">recently added support for Windows Subsystem for Linux (WSL) 2</a>, which may be another option.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="2-clone-supersets-github-repository">2.

Connecting Superset to your local database instance" title="Direct link to 5. 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.</li><li>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 see if there is an entry for <code>&quot;Gateway&quot;</code> and note the IP address.</li></ol></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/apache/superset/tree/master/docs/docs/installation/installing-superset-using-docker-compose.mdx" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_Z9Sw" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div><div class="col lastUpdated_vwxv"></div></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages"><a class="pagination-nav__link pagination-nav__link--prev" href="/docs/quickstart"><div class="pagination-nav__sublabel">Previous</div><div class="pagination-nav__label">Quickstart</div></a><a class="pagination-nav__link pagination-nav__link--next" href="/docs/installation/installing-superset-from-scratch"><div class="pagination-nav__sublabel">Next</div><div class="pagination-nav__label">Installing From Scratch</div></a></nav></div></div><div class="col col--3"><div class="tableOfContents_bqdL thin-scrollbar theme-doc-toc-desktop"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#installing-superset-locally-using-docker-compose" class="table-of-contents__link toc-highlight">Installing Superset Locally Using Docker Compose</a><ul><li><a href="#1-install-a-docker-engine-and-docker-compose" class="table-of-contents__link toc-highlight">1.
