cannot view web UI after start ambari:1.7.0 container

Hi @qinzhaokun, first of all thanks for the report. Do you use native Docker on Linux or Boot2Docker on OSX? Could you please try to download the resources from the container with curl or wget? And also please check the DNS server with nslookup or dig in the container. Is it possible to use newer version of Ambari, we suggest 2.1.0-consul.

Cheers,
Richard

hello, @mhmxs I use native docker on linux. I use curl in container. it shows:

root@zqin:/home/zqin/Desktop/ambari-1.7.0# docker exec -it amb0 bash
bash-4.1# curl http://s3.amazonaws.com/dev.hortonworks.com/HDP/hdp_urlinfo.json
curl: (6) Couldn't resolve host 's3.amazonaws.com'
bash-4.1# curl http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json
curl: (6) Couldn't resolve host 'public-repo-1.hortonworks.com'

the container cannot reslove the url!! but it is good out of container.
since the container does have nslookup and dig commands, I cannot check DNS server. I use yum command "install bind-utils" to set up them ,but it fails due to 404 Not found.

I have used the docker ambari of latest version but the same problem still exits.

How can I solve this and start the ambari server?

I tried on Centos and Ubuntu too with different Docker version. I started the Ambari server docker run -d --dns 127.0.0.1 --entrypoint /usr/local/serf/bin/start-serf-agent.sh -e KEYCHAIN= --name amb0 -h amb0.mycorp.kom sequenceiq/ambari:1.7.0 --tag ambari-server=true and it worked as well. It's hard to resolve network issues via a textfield here, but i guess your Docker configuration went wrong. Could you please export some extra Docker options before sourcing ambari-functions?

export $DOCKER_OPTS="--dns 127.0.0.1 --dns 8.8.8.8 --entrypoint /usr/local/serf/bin/start-serf-agent.sh -e KEYCHAIN=$KEYCHAIN"

And let's see what's happen? Which version of Docker do you use?

[qinzhaokun]

hello @mhmxs :
Thank you very much. it is the DNS problem. I can ping IP address in the container but cannot resolve any DNS address. I use 192.168.1.1 to instead of 127.0.0.1 like docker run -d --dns 192.168.1.1 --entrypoint /usr/local/serf/bin/start-serf-agent.sh -e KEYCHAIN= --name amb0 -h amb0.mycorp.kom sequenceiq/ambari:1.7.0 --tag ambari-server=true

and finally get no error in ambari server log and I can use curl $containerIP:8080 and it did return data. However, when checking ambari server status, it is still showing not running. It is normal?

root@Master:/home/hadoop# docker inspect --format='{{.NetworkSettings.IPAddress}}' amb0

I don't think so, but if cluster is running and nodes find each other it's good :)
