Hello,

Is this a greenfield newton?
Could you wget your http://172.16.1.2:8181/os-releases/14.0.1/requirements_constraints.txt  file reliably?
Are you using haproxy?  Are all the backends OK there?

Don’t hesitate to come by our irc channel, it’s probably easier to have a conversation there.

Best regards,
Jean-Philippe

Hi all,

Context:
openstact-ansible newton, tag: 14.0.1
OS: ubuntu 16.04 LTS

the pip command is unable to download packages form the repo container. I can reach the repo container from within galera container through the port 8181:

root at node01:~# lxc-attach -n node01_galera_container-368f269a
root at node01-galera-container-368f269a:~# nc -nzv 172.16.1.2 8181
Connection to 172.16.1.2 8181 port [tcp/*] succeeded!

However, when i run galera-install.yml playbook it throws the following error (but the root cause is pip_install role)  :
root at maas:/opt/openstack-ansible/playbooks# openstack-ansible galera-install.yml

Please advice on what i am doing wrong. I am stuck :)

Thank you,
