Jamie Gaskins<p>Having a 5% error rate for 30 seconds and then immediate recovery is honestly a great outcome. I have no doubt there are some edge cases to consider, but for a few hours of effort I&#39;m pretty happy with it.</p><p>This is the deployment strategy I spent 2 years trying to convince my previous employer to try.</p><p><a href="https://zomglol.wtf/tags/kubernetes" class="mention hashtag" rel="tag">#<span>kubernetes</span></a> <a href="https://zomglol.wtf/tags/sre" class="mention hashtag" rel="tag">#<span>sre</span></a></p>
Jamie Gaskins<p>This strategy worked really well! In my proof of concept, my health-check endpoint was set to return 500s above a 0.05% error rate (after a minimum of 1k requests). I had this config:</p><p>replicas: 30<br />minReadySeconds: 30<br />maxSurge: 5%<br />{liveness,readiness}Probe:<br /> failureThreshold: 3<br /> intervalSeconds: 10</p><p>Then I set it to use a known-bad image. K8s deployed 2 pods, which hit &gt; 0.05% threshold pretty quickly. K8s CLBOed it and never deployed more pods, so the app recovered in 30 seconds.</p><p><a href="https://zomglol.wtf/tags/kubernetes" class="mention hashtag" rel="tag">#<span>kubernetes</span></a></p>
Jamie Gaskins<p>Today I&#39;ve been experimenting with a slow-rollout canary idea for Kubernetes. Basically:</p><p>1. Set minReadySeconds to &gt;= your probe&#39;s `failureThreshold * periodSeconds`</p><p>2. Set maxSurge to something like 5% so it deploys small batches of pods at a time</p><p>3. Have the health-check endpoint return 500s if that pod&#39;s error rate is above your error threshold — I&#39;m using middleware to track error count vs total request count</p><p><a href="https://zomglol.wtf/tags/kubernetes" class="mention hashtag" rel="tag">#<span>kubernetes</span></a> <a href="https://zomglol.wtf/tags/k8s" class="mention hashtag" rel="tag">#<span>k8s</span></a></p>

Jamie Gaskins<p>Something must be wrong. CI passed on the first commit setting it up instead of requiring 18 failing attempts first.</p>

Jamie Gaskins<p>I just wrote a rudimentary time-series DB using <span class="h-card" translate="no"><a href="https://mastodon.social/@Dragonflydbio" class="u-url mention">@<span>Dragonflydbio</span></a></span> sets and streams.</p><p>Still needs some more work to be useful as a TSDB, like downsampling and a network interface, but it supports measuring and simple querying/aggregation in 120 lines of code, which is pretty amazing.</p>
