ambari-shell throw "Cannot get property 'items' on null object"

Hi,

I am using ambari-shell docker (
http://blog.sequenceiq.com/blog/2014/05/26/ambari-shell/). However,

docker run -it --rm sequenceiq/ambari-shell --ambari.host=localhost
--ambari.port=8080

threw error "Cannot get property 'items' on null object" even I can use
ambari web UI to sign in localhost:8080 using admin/admin.

Any idea will be highly appreciated!

Thanks for reply.

I did below:

1. get ip of the host.

sudo ip addr show docker0
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
state DOWN
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
    inet 172.17.42.1/16 scope global docker0
       valid_lft forever preferred_lft forever
    inet6 fe80::2cd2:3ff:fec4:809d/64 scope link
       valid_lft forever preferred_lft forever

2. use below command to invoke docker:

sudo docker run -it --rm sequenceiq/ambari-shell --network="host"
--ambari.host=172.17.42.1 --ambari.port=8080

The new error I got:
Cannot connect to Ambari http://172.17.42.1:8080/api/v1/

Any idea? Thanks.

Hi Lian,

localhost in the docker container is not the same as localhost on your
own computer.  The address where the container can talk to your
computer depends on the networking mode and OS.  See
