The image pulled fine, Docker didn&amp;rsquo;t complain, and then the container refused to start because the binary inside was compiled for x86_64 and the Pi is arm64. Nothing in &lt;code&gt;docker pull&lt;/code&gt; warns you about this — it happily hands you an incompatible image if that&amp;rsquo;s the only tag that exists.&lt;/p&gt;</description><pubDate>Tue, 20 Jan 2026 10:30:00 +0000</pubDate></item></channel></rss>
