Oh God. Story time.
I had an important CICD pipeline that published a dinky little web-thing that was important for customer experience. The first line of the final docker file was from company-node:base. I had all the source code. I had all the docker files. At no point was there ever a container named company-node let alone a tag of base.
The one and only version of this container was on the CICD server.
I'll keep this short and sweet.
The two hardest job interviews in IT are getting into the help desk, and getting out. Assuming you want to climb the ladder (it sounds like you do), does this new role set you up to get out of general help desk type roles or not?
Oh as for certs. One or two is useful if your trying to jump up rungs without experience. That said your get past HR and land with someone like me who won't even spend 20 seconds looking at your certs in the interview.
