Add ability to control Docker default route and route priority

dan273 · May 7, 2024, 12:13pm

For those that use docker IPvlans or multiple networks where the default route is important. You might have noticed docker sets the default route and route order based off the alphabet using the network names.

As a result you might have had to stick a letter in the alphabet into your network names in order to set the default route and priority for your container.

I opened a feature request to hopefully solve this both here on the forums and GitHub . If you would like to see a feature implemented where we get to choose the default route and configure priority if desired please like and comment on both this feature request and then one on GitHub so it can gain traction.

**Tell us about your request** A clear and concise description of what you want… to happen or the change you would like to see It would be nice to be able to set the default docker route to a docker network name defined in the compose and define the route priority in either a dictionary or list where the order in the yaml is the order docker would use. **Which service(s) is this request for?** Let us know which product(s) you want this for? Docker compose I think and maybe more under the hood I am not sure. **Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?** A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] There's no way currently to set the default route in docker or to set the priority it uses. Rather the default route and priority is currently selected based on the alphabet of the network name. That makes for a bad user experience and a lot of confusion when using docker networks. **Are you currently working around the issue?** A clear and concise description of any alternative solutions or features you've considered or are using today. My work around is to create networks but append an alphabet letter `a-example-network` for example so that network is the default network for example and subsequent networks would come after `a`. **Additional context** Add any other context or screenshots about the feature request here.
