How to update data? #27

Closed toton6868 closed 3 years ago

toton6868 commented 3 years ago

I have an SIT, UAT and Prod environment. Can you discuss a little bit how can I update my Prod environment without stopping the docker or having no maintenance mode? I have updated the data in the UAT environment. Is there any way to copy any folder or data from UAT to Prod? I know the docker cp but I do not know which folder needs to be replaced.

Can you describe your setup a little more? What data do you need updated? I guess the graph tiles?

Best paste your docker-compose.yml and explain a little more what exactly you want to achieve.

Yes, I want to update Graph Tiles. If I start processing the OSM data again then it will take a few minutes and the server will be unavailable. This is why I want to get a downtime less server maintenance mode.

Still no docker-compose.yml but if you're anywhere near the default setup then you have mapped a host directory to a container directory right? So, all you do is copy over the valhalla_tiles.tar from the builder to the runner host direcctory..

you'll have to restart the docker container though, no way around that. ref: https://github.com/valhalla/valhalla/issues/3117. I didn't get to that yet, but when it's finished there will be an endpoint on the http service allowing for an actor reset instead of exiting valhalla_service.
