Problem
We want to access the host machine port from the docker container, some use cases are you have existing DB in local machine and want to use.
Solution
-
open bash inside you docker container
-
run the following command
ip route show-
The command will return a result something like below
default via 172.15.0.1 dev eth0
172.15.0.0/16 dev eth0 proto kernel scope link src 172.15.0.4 -
The eth0 is the ip can be used to interact with host machine
-
To get a IP alone, we can use following IP
ip route show | awk '/default/ {print $3}'
-
