修改正在运行的Docker容器的hosts文件

Question

I need to add an entry to /etc/hosts file of a running container and get it applied same time. I manually modified the hosts file but the change did not get reflected on container. Is there any other we can do this? I want to do this without restarting the container.

Answer 1

if you check docker inspect {contaner id} as you can see it's different network subnet on your host. because of docker will create totally sandbox environment for you.

it will give you random IP when you docker up everytime.

so I recommend you use docker-compose to help you build your multi-services.
