With my current Vault docker compose file, I'm not able to login with my token which I've set as part of my docker compose file. When Vault container starts up - it provides his own root token to authenticate in vault server. And this keep on change whenever we bring up new container and developer has to note it down from the console every-time and use that token to login in Vault.
Instead of that I want to set as part of docker compose file - How can I do that.
Please find my docker compose file below:

version: '3'
services:
  myvault:
        image: vault
        container_name: myvault
        ports:
          - "192.168.99.100:8200:8200"
        environment:
           VAULT_SERVER: "http://192.168.99.100:8200"
           TOKEN: mysuper-secret-vault-token
        volumes:
          - ./file:/vault/file:rw
          - ./config:/vault/config:rw
        cap_add:
          - IPC_LOCK
