I was able to connect to the DB with Cloudbeaver, but it straight up wasn’t providing the diagram tab in the way the picture said it outta. The example pic even specifically is using a postgres DB as its example!

I pretty much had the exact same view, but no diagram tab. Unfortunately the wiki article doesn’t go into much detail, it just says:

“(if the tab is not presented then the object does not support the diagram presentation)”

With no information provided further listing off what is, and is not, supported for diagram presentation.

Lack of documentation it seems, which is unfortunate. It seemed like it has potential but I spent a good 20 minutes fiddling with it, trying different configurations and settings, nothing made it start working and it seems like (as is the case on a few of these tools) the ERD tooling is often a bit of an afterthought and poorly supported.

Many of the tools are sql first, ERD… third? fourth? forgotten and lacking most features :(

I have no idea how to respond to this. I wrote up a few attempts but it just felt weird.

Why do you think I need to explain what ERD stands for, in the context of my question?

Trying it out, the wiki says it has an ERD editor, but its documentation is kind of lacking.

It’s example image here: https://github.com/dbeaver/cloudbeaver/wiki/Entity-Diagrams

Shows it interacting with a postgres database, but when I try the same I am not getting a Diagram tab. Its also proving to be pretty awkward to try and work with.

So far best I have found is Azimutt, which is pretty close to what I want but its interface is lacking atm, and I couldnt get it to successfully connect to my postgres database in the end (kept giving NOT FOUND errors even though I tested inside the docker image to validate the connection and it could indeed TCP the postgres database’s port)

Let me know what specific questions you have that my post did not cover and I can try and help out.

I feel like I specified exactly what I am looking for and even gave some examples of existing (non self hosted) tools, so not sure what else to add.

Are you familiar with what an ERD is, with respect to database management?

Have you used tools like Luna/Moon, Navicat, Visual Paradigm, etc?

Im looking for such a tool, but self hosted via docker in the form of a Web App.

I have a K3OS cluster built out of a bunch of raspberry pis, it works well.

The big reason I like kubernetes is that once it is up and running with git ops style management, adding another service becomes trivial.

I just copy paste one if my e is ting services, tweak the names/namespaces, and then change the specific for the pods to match what their docker configuration needs, ie what folders need mounting and any other secrets or configs.

I then just commit the changes to github and apply them to the cluster.

The process of being able to roll back changes via git is awesome

If you set a secondary DNS server, your clients will just use it to get ads, negating the effect of your pihole.

Unless, of course, the second DNS server is a second pi-hole ;p

When the raspberry pi (running pi hole) is down for any reason

You can have 2 DNS servers provided over DHCP assignment, if this is really an issue for you (ideally it shouldnt) you should be running 2x PiHoles for failover protection, that way you can take 1 offline and all devices will auto swap to the second one for DNS.

This will also horizontally scale your DNS querying, as devices will just 50/50 flip flop between the two while both are online and it will sort of auto-load balance.

Largely speaking thats your best bet though, just 2x PiHoles for failover protection.

For DHCP just use one of the pi-holes DHCP, or your routers, or whatever, they all largely perform the same but I personally find the pi-hole’s DHCP settings to be easiest to work with (you can even super fast modify them by SSHing in and using nano/vim to text edit the config file, so instead of using a UI you can just copy-paste all the entries in quickly)

If you need to take the DHCP pi-hole offline, you can just flip DHCP on for the second one, however as long as new devices arent connecting you don’t actually need the DHCP server online once everyone has an IP assigned until their registration time is up (24 hours by default) so as long as you get the pi-hole back online quickly, you’re network typically wont even have a problem.
