I've tried

• dns: dns-server
• dns: 127.0.0.1
• dns: 192.168.2.170
• dns: 172.21.0.2 (dns-server container IP)

followed by sudo docker compose down && sudo docker compose up -d

But it never resolves jenkins.webdev or gitea.webdev to 192.168.2.170 like set up in dns-server

dns-server is working fine.

This is all inside a Ubuntu VM, my Windows Host machine has 192.168.2.170 as primary DNS and resolves jenkins.webdev and gitea.webdev just fine.

Edit: Updated my docker-compose.yml files to reflect current state, I've tried stopping all containers and then:

• Create a network inside the dns-server compose file

networks:
  dns-network:
    name: dns-network
    driver: bridge

• Adding that network to jenkins and gitea composer files

networks:
  gitea-network:
    name: dns-network
    external: true

services:
  server:
     networks:
      - gitea-network
  dns: dns-server

still doesn't work, inside gitea container I can ping dns-server and the ip shown is correct one, but if I ping webdev, gitea.webdev or jenkins.webdev I get ping: bad address

I can ping jenkins or gitea, and I see the local IPs but jenkins.webdev and gitea.webdev which point to my host IP 192.168.2.170 as defined in dns-server are bad address, and if I try using jenkins or gitea I get Delivery: Post "https://jenkins/gitea-webhook/post": dial tcp 172.20.0.5:443: connect: connection refused
