I have many services running on my server and about half of them use postgres. As long as I installed them manually I would always create a new database and reuse the same postgres instance for each service, which seems to me quite logical. The least amount of overhead, fast boot, etc.
But since I started to use docker, most of the docker-compose files come with their own instance of postgres. Until now I just let them do it and were running a couple of instances of postgres. But it’s kind of getting rediciolous how many postgres instances I run on one server.
Do you guys run several dockerized instances of postgres or do you rewrite the docker compose files to give access to your one central postgres instance? And are there usually any problems with that like version incompatibilities, etc.?
Do not run databases in Docker unless you know really well what you are doing.
It’s completely possible to run them correctly in Docker. But it’s far from trivial, and if you need to ask this, it means that you probably won’t be able to.
Nothing worse in Linux communities than gatekeeper answers like this.
It’s fine to point out that something’s challenging to someone who may be a novice, but to suggest it’s above them? Eat it. At the very least, provide a resource and let them confirm for themselves.
This right here… This whole community is about learning to do things for yourself. It might be after been given resources to learn you do decide its too much for you but people should be given the chance to discover that themselves.
Shout out to hack the box.
If you’re a noob or a veteran in any branch of IT looking for a good cybersecurity community/platform…
Most of us IT folk check the box of “knowledge peaks and valleys”. They’re the first community I’ve found that seems to actually respect the idea that someone might know way more about XSS and SQL injection in react apps than some other guy knows about binary exploits through packet disassembly, and that both of them are fucking experts and neither of them are lacking for not knowing what the other knows.
Cybersecurity communities too, there was one guy on [The Other Site] I saw awhile back who, whenever somebody asked a question about what they should do to secure X or Y or if Z security product was better than V because they just did general IT, would always default to something along the lines of “If you don’t know, don’t bother its above you and you should shell out $$$ to an actual firm otherwise you’ll be shelling out $$$$ to another firm to clean up your mess”
Surprise surprise, when I googled his username (The fact I was even able to do this isnt a great sign for a “security professional” IMO lmao) he actually owned one of those “Databreach Triage” firms…yea…I’m sure there was no conflict of interest whatsoever lmaoo
