Someone recommended it for keeping my containers up to date automatically. I checked out the [repo](https://github.com/containrrr/watchtower) and it seems too good to be true. It just updates your containers when a new image is available and everything just works out of the box? I'm a bit scared of just leaving it alone in case it might break something. The fact that it doesn't come with a gui also scares me a bit. Does anyone here use it and can recommend it? Any horror stories?

I've had to reset my Ubuntu server a couple of times in the last year and there's one thing I noticed that happens to my MariaDB container: The IP address goes up by one each time. For example, it was [172.17.0.10](https://172.17.0.10) and now its [172.17.0.11](https://172.17.0.11). The ports remain the same but this breaks any app that's using the DB since the app is still looking to connect to .10 and not .11. I'm not quite sure if this happens to other containers (I think it might) but other containers connect using the host + port. MariaDB connects using the IP address shown in portainer. The one that matches the network bridge. I'm not well-versed in networking and I've been asking about recommendations for Udemy/Coursera courses on the topic (Feel free to suggest one). If possible, I'd like to revert the container's Ip address back to [172.17.0.10](https://172.17.0.10) and prevent it from changing again, OR find a way to connect apps to the container using the localhost instead of the container IP address. ​ My workaround has been to go to the affected apps and point them to the new IP address when it changes but I'm hoping to find a way to eliminate the need for this. Thoughts?

I set up the [Nginx proxy manager container](https://nginxproxymanager.com/) to avoid the "not secure" warnings on my internal Docker containers. They all seem to work with my duck.dns SSL certificates and I can access them using custom domain names (e.g. [Plex.duck.dns.org](https://Plex.duck.dns.org)) but when I try it with Portainer, I get this error on Chrome. Firefox and other browsers don't show the error but tell me that my connection is still not secure. Does anyone here know why and how I could fix it? https://preview.redd.it/7rsxc10mh60c1.png?width=897&format=png&auto=webp&s=d0532cef522c6b7fb2c482c8d946b9a0bb7fd6a0

I have a couple dbs as Docker containers on my homelab and used accross multiple applications and the main ones are PostgreSQL and MariaDB. I spun up a pgAdmin container in order to vizualize my dbs. PostgreSQL worked like a breeze but for some reason MariaDB cannot be added to pgAdmin no matter what I try. I keep getting an error saying `"Unable to connect to server: connection to server at "IP', port 3306 failed: received invalid response to SSL negotiation: q` Neither container has SSL certs associated with them, and I even removed the SSL parameter from the pgAdmin configuration. I have been able to add this MAriaDB container to a bunch of other aplications (nextcloud, paperless, bookstack, etc.) with no issues so I'm not sure what the problem is with pgAdmin. Any help would be appreciated.

I have been on this sub and playing around with selfhosting for almost two years now but I feel like I've barely scratched the surface. I often feel inadequate when I see people on this sub discussing what I consider to be advanced networking terms and technologies, especially when discussing remote access. Will getting a certification like Network+ help me feel more comfortable managing my homelab? If not, can someone recommend any resources I should look into to get good at being my own sysadmin?

I have a decent server with a bunch of services I use regularly on a Windows and ubuntu server VMs. Here's a screenshot of some of them: https://preview.redd.it/xvg4w5fqt9wb1.png?width=1306&format=png&auto=webp&s=4670d51216d8c6884edbfb4090f99b2b645671ec I also happen to have a spare mini pc. It was originally a Chromebox that I converted to a TrueNas server a few years back, then abandoned it after building my current server. I want to put it back in use but I'm not sure what to do with it and I'm hoping to get some suggestions. It has 6gb of ram and 128gb of storage. I believe the current OS is TrueNas core but I can boot pretty much anything on it. I was thinking maybe a small SMB share for my family though we don't really need it. Any suggestions from my self-hosting bretheren?

[SOLVED] This might be the dumbest thing to happen to me. I've been running a home server for over a year now with Proxmox as my main OS and two VMs on it (Windows server 2019 & Ubuntu server). It has been a long time since I've needed to access Proxmox for anything and I recently lost all my browser history on Chrome. It just occured to me that I should probably save my proxmox ip address but for the life of me I don't remember what it is. It is not in my browser history because that was recently reset. I have access to both VMs so I'm hoping there's a way to find the proxmox IP address from them. ​ So far I have tried `ip route` on the Linux VM and `ipconfig` on the Windows VM. This is only getting me the ip of the VMs. Am I screwed or is there a way for me to get the Proxmox ip? EDIT: Thank you to those who suggested the router logs. I recognized the IP there and was able to access it!

I have a couple Android phones with little resell value and I'm wondering what I could do with them on my spare time. Not sure if this is the right sub to ask but figured it could be a good start to see if anyone here has done anything with phones.
