Kolla OpenStack deployment fails with "haproxy : Waiting for virtual IP to appear"

  • 772

I'm trying to deploy OpenStack Queens with kolla-ansible (7.0.0) on Ubuntu hosts, following the official guide.

After successful bootstrap-servers and precheck the deploy command fails:

RUNNING HANDLER [haproxy : Waiting for virtual IP to appear] **********************************************************  
fatal: [testcloudcontrol01]: FAILED! => {"changed": false, "elapsed": 300, "msg": "Timeout when waiting for 10.52.41.98:3306"}  
fatal: [testcloudcontrol02]: FAILED! => {"changed": false, "elapsed": 300, "msg": "Timeout when waiting for 10.52.41.98:3306"}

The reason for the check to fail is that the kolla_internal_vip_address does not come up.

globals.yml

config_strategy: "COPY_ALWAYS"
kolla_base_distro: "ubuntu"
kolla_install_type: "binary"
openstack_release: "queens"
kolla_internal_vip_address: "10.52.41.98"
kolla_internal_fqdn: "testcloudapi.example.com"
kolla_external_vip_address: "{{ kolla_internal_vip_address }}"
kolla_external_fqdn: "{{ kolla_internal_fqdn }}"
network_interface: "ens160"
api_interface: "ens160"
storage_interface: "ens161"
keepalived_virtual_router_id: "148"

I'm currently fixed on queens because I want to replicate our production environment for testing.

The output of ip addr on one of the nodes where haproxy is supposed to deploy:

The nodes are VMware virtual machines with VMXNet3 nics.

[message repeats until I stop the container]

That's it, both keepalived instances stay in the FAULT state, the IP address is not activated on any of the VMs.

I went through this question and the answer, even though I don't have the error messages in the log files:

  • keepalived_virtual_router_id has been changed and is unique
  • I ran kolla-genpwd again. I confirmed that keepalived_password is set in /etc/kolla/passwords.yml
  • kolla_internal_vip_address is accessible from network_interface. The main IP on that interface is in the same network. I can manually set the additional IP address and it works.
  • kolla-ansible prechecks passes
  • selinux is not active on Ubuntu

On the hypervisor side I tried enabling Promiscuous mode for the port group of that interface. That didn't make a difference.

    So, after running into the same problem on bare metal I dug deeper into the problem. Turns out it wasn't keepalived, but the haproxy container that had the problem.

    The haproxy container keeps restarting because haproxy is started with the command line parameter -W, which does not exist in the haproxy version that is shipped in the container.

    Running command: '/usr/sbin/haproxy -W -db -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid'
+ exec /usr/sbin/haproxy -W -db -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid
HA-Proxy version 1.6.3 2015/12/25
Copyright 2000-2015 Willy Tarreau <[email protected]>

Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ]
        [ -p <pidfile> ] [ -m <max megs> ] [ -C <dir> ] [-- <cfgfile>*]
        -v displays version ; -vv shows known build options.
        -d enters debug mode ; -db only disables background mode.
        -dM[<byte>] poisons memory with <byte> (defaults to 0x50)
        -V enters verbose mode (disables quiet mode)
        -D goes daemon ; -C changes to <dir> before loading files.
        -q quiet mode : don't display messages
        -c check mode : only check config files and exit
        -n sets the maximum total # of connections (2000)
        -m limits the usable amount of memory (in MB)
        -N sets the default, per-proxy maximum # of connections (2000)
        -L set local peer name (default to hostname)
        -p writes pids of all children to this file
        -de disables epoll() usage even when available
        -dp disables poll() usage even when available
        -dS disables splice usage (broken on old kernels)
        -dV disables SSL verify on servers side
        -sf/-st [pid ]* finishes/terminates old pids.

    Hence, the haproxy container keeps restarting. The keepalived container on the other hand, is configured with a check script for keepalived that keeps exiting with an error:

    Fri Feb 15 08:17:14 2019: /check_alive.sh exited with status 1
Keepalived_vrrp[12]: /check_alive.sh exited with status 1

    This check script is very simple, it checks the status of haproxy via a socket file:

    #!/bin/bash

# This will return 0 when it successfully talks to the haproxy daemon via the socket
# Failures return 1

echo "show info" | socat unix-connect:/var/lib/kolla/haproxy/haproxy.sock stdio > /dev/null

    So ... as long as haproxy is called with the invalid parameter and doesn't start, keepalived stays in FAULT state, with no floating IP up.

    Using grep -R "haproxy -W" * I found that the command line for haproxy is defined in the file /usr/local/share/kolla-ansible/ansible/roles/haproxy/templates/haproxy.json.j2. I removed the -W parameter from the command line, which resulted in haproxy starting properly and keepalived changing to MASTER state with configuration of the floating IP.

    There is already a bug report open on Launchpad regarding this issue. There is also a slightly different solution in the comments (changing the same file).

    This modification will of course be reverted when the file is updated. If you have the same problem, please log into Launchpad and mark that the bug (which was reported on 2018-06-08) affects you, so it gets priority and gets fixed.
