A implantação do Kolla OpenStack falha com "haproxy: aguardando o IP virtual aparecer"

  • 772

Estou tentando implantar o OpenStack Queens com kolla-ansible (7.0.0) em hosts Ubuntu, seguindo o guia oficial .

Depois de bem-sucedido bootstrap-serverse prechecko deploycomando falhar:

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"}

A razão para a verificação falhar é que o kolla_internal_vip_addressnão aparece.

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"

Atualmente estou fixo em rainhas porque quero replicar nosso ambiente de produção para testes.

A saída de ip addrum dos nós em que o haproxy deve implantar:

[message repeats until I stop the container]

É isso, ambas as instâncias keepalived ficam no estado FAULT, o endereço IP não é ativado em nenhuma das VMs.

Passei por essa pergunta e a resposta , mesmo não tendo as mensagens de erro nos arquivos de log:

  • keepalived_virtual_router_id foi alterado e é único
  • Eu corri kolla-genpwdnovamente. Eu confirmei que keepalived_passwordestá definido em/etc/kolla/passwords.yml
  • kolla_internal_vip_addressé acessível a partir de network_interface. O IP principal dessa interface está na mesma rede. Posso definir manualmente o endereço IP adicional e funciona.
  • kolla-ansible precheckspassa
  • selinux não está ativo no Ubuntu

No lado do hipervisor, tentei habilitar Promiscuous modeo grupo de portas dessa interface. Isso não fez diferença.

    Então, depois de encontrar o mesmo problema no bare metal, me aprofundei no problema. Acontece que não foi keepalived, mas o contêiner haproxy que teve o problema.

    O contêiner haproxy continua reiniciando porque o haproxy é iniciado com o parâmetro de linha de comando -W, que não existe na versão do haproxy fornecida no contêiner.

    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.

    Portanto, o contêiner haproxy continua reiniciando. O contêiner keepalived, por outro lado, é configurado com um script de verificação para keepalived que continua saindo com um erro:

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

    Este script de verificação é muito simples, ele verifica o status do haproxy através de um arquivo de soquete:

    #!/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

    Então ... enquanto haproxy é chamado com o parâmetro inválido e não inicia, keepalived permanece no FAULTestado, sem IP flutuante para cima.

    Usando grep -R "haproxy -W" *descobri que a linha de comando para haproxy está definida no arquivo /usr/local/share/kolla-ansible/ansible/roles/haproxy/templates/haproxy.json.j2. Eu removi o -Wparâmetro da linha de comando, o que resultou no haproxy iniciando corretamente e no keepalived mudando para o MASTERestado com a configuração do IP flutuante.

    Já existe um relatório de bug aberto no Launchpad sobre este problema . Há também uma solução ligeiramente diferente nos comentários (alterando o mesmo arquivo).

    Essa modificação será, obviamente, revertida quando o arquivo for atualizado. Se você tiver o mesmo problema, faça login no Launchpad e marque que o bug (que foi relatado em 2018-06-08) afeta você, para que tenha prioridade e seja corrigido.
