Lets face it: you are little more than junior devops Engineer (I suspect, you are not giving much bachground, but then due to the nature of your post...)
You need some sort of guidance. Try to find a formal or informal mentor. Once again, given tour questions, I suspect it will be the latter.
Ask for training, for instance Containers conferences from the Linux Foundation. You will need it. Ask for monthly subscripyions to Safari from OReilly and Udemy. They have to have a generous amount of money ser aside for external training if they want to save on not having senior guys giving you a hand.
Youtube is also your friend, loads of conferences there.
Join the certification path and ask for the relevant training.
Udemy has some introductions to the devops theme that will save you lots of time getting your feet wet, however they often end when things starting getting interesting.
Network with similar people in events and over the Internet. They will have overlaping interests and often a lit bit of advice that will offer clues or insights to your particular problems.
Put together a test network; do not test on your production systems. If there are no resources dedicated to that, ask for a paid cloud services account, like AWS or Azure. (I prefer AWS)
I hate to break it to you, but your boss expectations without having a senior type mentoring you are unrealistic. Been there, done that, and reinvented myself a couple of times, for you to both adapt to a new infrastructure, new technologies and being fully productive it takes normally 1 to 1.5 years as a full time job.
Having said that, enjoy also this period as you can, it is a great opportunity to learn and enter a very interesting career path.
Unfortunately, it is expected of you to define your own path; the big picture will come with experience, give it time. If you are fortunate enough, they will get out of way after that happens. Do not expect someone to define it for you, that will be your job. Management is often clueless about this, and if you are lucky, they wont have delusions they have a clue, and will give you space over time to take your own technical decisions.
I was lucky enough in one of the jobs to have the guidance of someone who was experienced in the industry as a CEO and was a stepping stone in my career. He gave precious advice, however he was also savvy enough to stay out of my way of growing. Ditto for colleagues. Do not impose too much on them. With time you will also find out the right balance. I do agree with others that a formal meeting each week is the right idea. Over time, daily formal meetings are unproductive.
Do not get too stressed out, they are paying what they are getting, and they do know that. A devops senior type can command a much higher salary.
