<p><strong>UPDATE</strong>: Apologies for perhaps causing controversy but it seems like there was another cronjob running that was also calling a function that was grabbing those apiKeys from the DB but I was not sure until I seperated the part where it was grabbing them from the environment variables ;_;.
So basically this whole post is wrong and one container was not grabbing env variables from another container. I am so ashamed I wanted to delete this question but not sure if a good idea or not?</p>
<hr />
<p>Kubernetes pod running two of basically the same NodeJS application seems to be taking environment variables from another container, I logged the variable and it logged me the correct one but when it makes a request it seems to show two different results.</p>
<p>These variables are taken from two different secrets.
I have checked inside of each container that they do indeed have different env variables but for some reason inside of NodeJS when it makes these requests out to a third-party API it grabs both of the variables.
Yes, they do have the same name.</p>
<p>In the image below you, can see some logs these entries show the Authorization header for an <strong>http</strong> request, and this header is taken from an environment variable. Technically speaking it should always stay the same but it grabs the other one for some reason as well.
