|
|
Istio configuration, as well as gives general insights to improve your configuration.
|
|
It can run against a live cluster or a set of local configuration files.
|
|
It can also run against a combination of the two, allowing you to catch problems before you
|
|
apply changes to a cluster.</p><p>To get started with it in just minutes, head over to the <a href=/v1.12/docs/ops/diagnostic-tools/istioctl-analyze/>documentation</a>.</p><h2 id=designed-to-be-approachable-for-novice-users>Designed to be approachable for novice users</h2><p>One of the key design goals that we followed for this feature is to make it extremely approachable.
|
|
This is achieved by making the command useful without having to pass any required complex parameters.</p><p>In practice, here are some of the scenarios that it goes after:</p><ul><li><em>“There is some problem with my cluster, but I have no idea where to start”</em></li><li><em>“Things are generally working, but I’m wondering if there is anything I could improve”</em></li></ul><p>In that sense, it is very different from some of the more advanced diagnostic tools, which go
|
|
after scenarios along the lines of (taking <code>istioctl proxy-config</code> as an example):</p><ul><li><em>“Show me the Envoy configuration for this specific pod so I can see if anything looks wrong”</em></li></ul><p>This can be very useful for advanced debugging, but it requires a lot of expertize before you
|
|
can figure out that you need to run this specific command, and which pod to run it on.</p><p>So really, the one-line pitch for <code>analyze</code> is: just run it! It’s completely safe, it takes no thinking,
|
|
it might help you, and at worst, you’ll have wasted a minute!</p><h2 id=improving-this-tool-over-time>Improving this tool over time</h2><p>In Istio 1.4, <code>analyze</code> comes with a nice set of analyzers that can detect a number of common issues.
|
|
But this is just the beginning, and we are planning to keep growing and fine tuning the analyzers with
|
|
each release.</p><p>In fact, we would welcome suggestions from Istio users. Specifically, if you encounter a situation
|
|
where you think an issue could be detected via configuration analysis, but is not currently flagged
|
|
by <code>analyze</code>, please do let us know. The best way to do this is to <a href=https://github.com/istio/istio/issues>open an issue on GitHub</a>.</p></div><nav class=pagenav><div class=left><a title="Provision and manage DNS certificates in
