I have a Kubernetes cluster which have a few different services in it. A flask server, an nginx server for static content, traefik and a metabase service.
It all works fine, however, sometimes, when I'm going on the metabase website, the metabase website is really slow and the main website too. I go down for a few minutes.
I don't understand why the metabase service affect the access to the website. The memory/cpu of the cluster doesn't seems to be overloaded. When I fetch the static content from the flask service, I works fine. So it seems link to the network/outside access.
I'm lost. What should I check ?
