Two things here:

- Your job won't always involve doing things you like doing. If you're stuck in jobs which use tech you don't like, at some point you have to accept that said tech is here to stay and spend just your work time on it. It's not a great choice, but jobs are like that more often than not.

- If, as you say, containerisation is a bad idea for most companies (I wouldn't know - my company uses the "boring" way of deploying our services), you just need to point out how it's hindering them. I'm sure when management starts wondering why their platform bills are going through the roof or features take ages to go live, you can pitch the boring way to management and make your case with actual facts.
