I self-host using Docker, and it&#8217;s been incredibly easy. However, with the slightest oversight, you can accidentally weaponize a container against your hardware. I learned the hard way when I choked my device with unconstrained memory limits and rogue logs.<\/p>\n<p>This is just one of the many Docker mistakes I&#8217;ve made over the years. Here are the ones I regret the most and how I fixed them.<\/p>\n<h2 id=\"i-ignored-memory-limits\">\n                        I ignored memory limits<br \/>\n               <\/h2>\n<h3 id=\"one-container-ate-everything\">\n            One container ate everything<br \/>\n    <\/h3>\n<p>        Afam Onyimadu \/ MUO<\/p>\n<p> I&#8217;m used to having operating systems manage memory use. For instance, when I open several browser tabs, the browser freezes idle background tabs to free up RAM. I assumed that&#8217;s how Docker worked, but I was wrong.<\/p>\n<p>It was one afternoon, after my server ground to a halt with timed-out SSH connections and an unresponsive dashboard, that I learned the lesson. I initially thought it was a failing hardware component, but it turned out to be a single container hogging too much memory.<\/p>\n<p>By default, Docker doesn&#8217;t impose memory limits on containers. Without asking for permission, Linux&#8217;s OOM killer terminates processes to recover memory when the system runs out of RAM. Even important processes may be terminated.<\/p>\n<p>The OOM killer prioritizes processes by a score it calculates automatically, which&#8230;<\/p>\n<p><a href=\"https:\/\/www.makeuseof.com\/beginner-docker-mistakes-made-took-homelab-offline-how-fixed\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>4 beginner Docker mistakes I made that took my homelab offline \u2014 and how I&#8230;<\/p>\n","protected":false},"author":1,"featured_media":272163,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/static0.makeuseofimages.com\/wordpress\/wp-content\/uploads\/wm\/2026\/05\/htop-on-linux-mint.jpg?w=1600&h=900&fit=crop","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-272162","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/272162"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=272162"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/272162\/revisions"}],"predecessor-version":[{"id":272164,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/272162\/revisions\/272164"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/272163"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=272162"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=272162"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=272162"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
