</code></pre><h2id=parameters>Parameters</h2><p>Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <code><external>:<internal></code> respectively. For example, <code>-p 8080:80</code> would expose port <code>80</code> from inside the container to be accessible from the host's IP on port <code>8080</code> outside the container.</p><h3id=ports-p>Ports (<code>-p</code>)</h3><table><thead><tr><thalign=center>Parameter</th><th>Function</th></tr></thead><tbody><tr><td></td><td></td></tr></tbody></table><h3id=environment-variables-e>Environment Variables (<code>-e</code>)</h3><table><thead><tr><thalign=center>Env</th><th>Function</th></tr></thead><tbody><tr><tdalign=center><code>PUID=1000</code></td><td>for UserID - see below for explanation</td></tr><tr><tdalign=center><code>PGID=1000</code></td><td>for GroupID - see below for explanation</td></tr><tr><tdalign=center><code>WALLET_URL=https://wallet.linuxserver.io/#/nano.linuxserver.io/</code></td><td>Hosted wallet endpoint to use.</td></tr><tr><tdalign=center><code>RPC_URL=https://nano.linuxserver.io:7077</code></td><td>RPC endpoint to publish blocks to and ingest account information.</td></tr><tr><tdalign=center><code>FAUCET_KEY=XXXXXXXXXXXXX</code></td><td>The private key for your faucet account.</td></tr><tr><tdalign=center><code>DISCORD_KEY=XXXXXXXXXXXXX</code></td><td>Discord api key for the bot.</td></tr><tr><tdalign=center><code>FAUCET_AMOUNT="1000"</code></td><td>Amount to distribute to individual Discord users in Nano.</td></tr></tbody></table><h3id=volume-mappings-v>Volume Mappings (<code>-v</code>)</h3><table><thead><tr><thalign=center>Volume</th><th>Function</th></tr></thead><tbody><tr><tdalign=center><code>/config</code></td><td>Database and Radarr configs</td></tr></tbody></table><h2id=environment-variables-from-files-docker-secrets>Environment variables from files (Docker secrets)</h2><p>You can set any environment variable from a file by using a special prepend <code>FILE__</code>.</p><p>As an example:</p><pre><code>-e FILE__PASSWORD=/run/secrets/mysecretpassword
