[SOLVED] No route to host - connectivity problem between kafka and zookeeper


(Ozma) #1

Hi,

I was using 2 docker containers and the second can’t connect the first.
These are the containers (see the link):

  $ docker run -d --name zookeeper jplock/zookeeper:3.4.6
  $ docker run -d --name kafka --link zookeeper:zookeeper ches/kafka
  • My env is linux mint 17.1.
  • The problem doesn’t occurs when using docker.io installation (installed from mint/ubuntu repository, but it is too old docker - ver-1.0.1)
  • The problem only happens when I am running with the docker that is installed from the web (“wget -qO- https://get.docker.com/ | sh”).
  • Running ping from the “kafka” docker to the “zookeeper” I can see that the connectivity exists.
  • The problem exists in 2 linux-mint" machine but not in a third one (all were updated in the same way - apt-get update/upgrade).
  • I have cleaned and reinstall docker (stop service, uninstall, reboot, install)
  • The error from the log can be found below.

** Any idea will be valued!

I’ve found a solution:
remove any installed docker.
install a specific version:

sudo aptitude install lxc-docker-1.6.2 

This version works fine and it is also not old.
This 1.6.2 is not in the repository of mint/ubuntu I had to install first the web script, then uninstall docker and finally install using the above commend
The following will be required as well:

 sudo aptitude install apparmor
