Why can't you change the ip address?

Question

Docker

Why doesn't the IP change?

module.exports = {
    mode: "universal",
    
    cache: process.env.NODE_ENV === "production",
    
    env: {
        api: process.env.NODE_ENV === "development" ? "http://127.0.0.160:8090" : "https://api.domain.cn"
    },
    
    server: {
        port: process.env.NODE_ENV === "development" ? 3800 : 3001,
        host: process.env.NODE_ENV === "development" ? "127.0.0.1" : "0.0.0.0"
    },
...

...
"scripts": {
    "dev": "NODE_ENV=development nuxt",
    "build": "NODE_ENV=production nuxt build",
    "start": "NODE_ENV=production nuxt",
    "generate": "nuxt generate"
  },
...

The whole thing works in the docker
. When I run
it, I see in the logs

is not what you need
Although this configuration works fine on another VPS In
general, I noticed that ip changes randomly.
