Hi Alejandro, The error message "http://10.8.9.54:2379 exceeded header timeout" indicates that Docker Daemon was not able to access the URL "http://10.8.9.54:2379", which is supposed to be the ETCD endpoint. If you run "curl http://10.8.9.54:2379" in compute host. Are you able to reach that endpoint?

I tried to launch another container without defining a network and without executing any command, and it also had the same error. I can launch container from the computer node cli with docker commands, the errors are when i try to launch them from the controller CLI. I run a docker run hello-world at the compute node and everything went fine Wen u runned openstack appcontainer create hello-world i had exactly the same error
