Hi,
I have a problem with connect to my docker containers and I can’t figure out how to resolve it. Could you help me?
// I’m not a specialist of networks, I don’t understand all this stuff, sorry for that.
I’m using Docker for Windows… on Windows
Docker network configuration (from settings window) is:
Hyper-V subnet: 10.0.75.0/28
Docker subnet: 172.28.5.0/24
I created a Docker network
docker network create --driver=bridge --subnet=172.28.0.0/16 --ip-range=172.28.5.0/24 --gateway=172.28.5.254 webdev
I added a route on my host
route add -p 172.28.0.0 MASK 255.255.0.0 10.0.75.2
I created a container
docker run `
-d `
--name pma `
--network webdev `
--ip 172.28.0.12 `
-p 8012:80 `
-p 8112:443 `
--link mysqld:db `
-e PMA_USER=root `
-e PMA_PASSWORD=qwerty `
phpmyadmin/phpmyadmin
Everything was working by the months, but yesterday stopped.
I mean:
- I can open a phpmyadmin via http://localhost:8012
- I can NOT open a phpmyadmin via http://172.28.0.12 (ERR_CONNECTION_TIMED_OUT)
This is a ipconfig /all result from my host
