why I can't ping my docker container?
I run a docker container, which is named “redis”. I want to use the “redis” container redis service, but I can’t ping the container!
As the picture shows, my “redis” container is IP address is 172.17.0.15, but I can’t connect to it.
I want to use the redis services. What is wrong with my configuration?

Because you’re not on the same network. Containers are started on their own network by default, separate to the host’s network.
If you run:
docker run -it debian ping 172.17.0.15
You should find it works. Even better, you can link containers and refer to them by name:
$ docker run -d --name redis redis $ docker run --link redis:redis redis redis-cli -h redis ping PONG
If you really want to access redis from your host, just publish a port through to the host:
$ docker run -d -p 6379:6379 redis
You should now be able to reach it at
localhost:6379 on the host.
