I'm using 1Panel to manage my Docker setup, but I'm running into an issue where my containers keep changing their IP addresses. Right now, I'm using a bridge network configuration. Is there a way to assign static IP addresses to my containers so they remain consistent and don't cause problems for my applications?

You actually shouldn't manage containers like VMs. But if you really need to keep IP addresses static, check the IPAM settings in your network configuration. You can assign static addresses there. Just make sure the DHCP pool is smaller than your subnet range and doesn't overlap with the static addresses you're using.
It sounds like you're encountering an XY problem. What exactly is the issue you're facing with the IP changes? Are your domain names not resolving to the new IPs, causing application breakage?
The best approach is to create a custom network for your containers. From there, you can either set their IP addresses manually or, even better, use DNS and refer to them by their container names.
