Change docker dns option on docker-compose

Question

Problem: My container not find others hosts outside the swarm if ndots=0 on resolv.conf .I did some tests and if a remove or change ndots to 1 works.

There's some way to delete or change the option ndots on docker-compose or in my docker network ?

Answer 1

the network inside the container is different than the one on the host computer so you may use a bashscript to change resolv.conf inside the container or just use your host network as the containers network with --net=host flag

docker run -it --net=hos -p 8080:8080 containerName

the flag above uses host computer network so you have to use same ports inside and outside of container
