Docker (stopped) container has no IP address
The reason is simple based on the output of docker ps -a
result that you posted in the top.
You might have noticed that it is showing status Exited (1) 5 minutes ago
for the container whose id is ca030d3cf1c2
. That means, container is stopped.
Once container is stopped, it will not have any IPAddress
. That's the reason being shown empty
in the result of docker inspect ca03
which you posted.
Start the container, you would get the IPAddress
.
To your last question, you may have that configuration for port forwarding using your docker-compose.yml
file. Or you may also do it while running docker run
using -p <hostport>:<container port>
option.
Hope this is helpful.
