I use docker-compose to charge my container, I need to connect between container and host, so I need an ip that I always could access, I know docker's default ip on linux is 172.17.0.x, but something strange is that every time I start up the container the ip will change, from 172.18.0.1 to 172.19.0.1 to 172.20.0.1 and etc ..., step by step

Instead of relying on the ip address, what about just using port forwarding to expose the service you need to access on the host? – larsks Jan 06 '20 at 03:48
