    This is why I said “most containers most of the time should”. It’s a bad practice to write to the inside of the container and a better practice to treat them as immutable. You can go as far as actively preventing them from writing to themselves when you build them or in certain container runtimes, but this is not usually how they work by default.

    Also a container that is stopped and restarted will not lose its internal changes in most runtimes. The container needs to be deleted and recreated from the image to do that

    A million times this. A major difference between the way most vms are run and most containers are run is:

    VMs write to their own internal disk, containers should be immutable and not be able to write to their internal filesystem

    You can have 100 identical containers running and if you are using your filesystem correctly only one copy of that container image is on your hard drive. You have have two nearly identical containers running and then only a small amount of the second container image (another layer) is wasting disk space

    Similarly containers and VMs use memory and cpu allocations differently and they run with extremely different security and networking scopes, but that requires even more explanation and is less relevant to self hosting unless you are trying to learn this to eventually get a job in it.

    I work for a healthcare company and when we launched we made a huge deal about only using Linux on our backend and only giving Macs to employees. It’s been almost 10 years and we’ve hired a small army of morons since then and they fired our CTO. These idiots have demanded windows so they can “do analytics” despite all our analytics being in looker and dbt and a bunch of fucking business bros in the csuite and vp level who demanded windows laptops because they just like it. They eventually canned our head of IT ans well and replaced him with a dumbass and that guy is currently trying to take MacBooks away from engineering. Then the head of “cloud engineering” just started outsourcing half our shit to consultants who keep building one off snowflake windows machines because nobody gives a shit anymore. So what used to be a clean ecosystem is now a giant botched pile of lowest effort garbage.

    Stay away from this entire industry. There’s some brain rot where they only hire people with healthcare backgrounds even if the role has nothing to do with healthcare. What that turns into is people from ancient out of date orgs who have no idea what they are doing being hired over people from legitimate tech roles or any other background that is more advanced in other fields and the company will always slowly roll backwards into stupidity.
