问题
采用Neutron LBaaS v2实现HTTPS Health Monitors时的配置如下(步骤见附件 - Neutron LBaaS v2)
backend 52112201-05ce-4f4d-b5a8-9e67de2a895amode tcpbalance leastconntimeout check 10soption httpchk GET /http-check expect rstatus 200option ssl-hello-chkserver 37a1f5a8-ec7e-4208-9c96-27d2783a594f 192.168.21.13:443 weight 1 check inter 5s fall 2server 8e722b4b-08b8-4089-bba5-8fa5dd26a87f 192.168.21.8:443 weight 1 check inter 5s fall 2
这种配置会有一个问题, 当使用自定义签名证书时一切正常, 但使用机构颁发的证书时反而有问题.
1, 对于ssl check, 严格一点的是check-ssl, 但haproxy没有证书不支持严格的客户端认证, 所以需添加"check check-ssl verify none"参数禁止对客户端参数进行验证. lbaasv2由于久远不支持(那时都还是haproxy 1.7以前必须不支持), ocatavia则有对ssl check的支持.(https://github.com/openstack/octavia/blob/master/octavia/common/jinja/haproxy/templates/macros.j2)
154 {% if pool.health_monitor.type == constants.HEALTH_MONITOR_HTTPS %}
155 {% set monitor_ssl_opt = " check-ssl verify none" %}
下面的配置works
backend 79024d4d-4de4-492c-a3e2-21730b096a37mode tcpbalance roundrobintimeout check 10soption httpchk GET /http-check expect rstatus 200fullconn 1000000option allbackupstimeout connect 5000timeout server 50000server 317e4dea-5a62-4df0-a2f1-ea7bad4a9c5d 192.168.21.7:443 weight 1 check check-ssl verify none inter 5s fall 3 rise 4
但是似乎ocatavia的client有点问题, 它设置出来的是:
option httpchk None Nonehttp-check expect rstatus Noneserver 317e4dea-5a62-4df0-a2f1-ea7bad4a9c5d 192.168.21.7:443 weight 1 check check-ssl verify none inter 5s fall 3 rise 4ubuntu@zhhuabj-bastion:~/ca3$ openstack loadbalancer healthmonitor create --delay 5 --max-retries 4 --timeout 10 --type HTTPS --name https-monitor --http-method GET --url-path / --expected-codes 200 pool1
http_method is not a valid option for health monitors of type HTTPS (HTTP 400) (Request-ID: req-2d81bafa-1240-4f73-8e2e-cb0dd7691fdb)
2, ssl backend side采用了严格的客户端认证的话, 需改用TLS-HELLO check (https://docs.openstack.org/octavia/latest/user/guides/basic-cookbook.html)其实已经有说明, 如下:
HTTPS health monitors operate exactly like HTTP health monitors, but with ssl back-end servers. Unfortunately, this causes problems if the servers are performing client certificate validation, as HAProxy won’t have a valid cert. In this case, using TLS-HELLO type monitoring is an alternative.
TLS-HELLO health monitors simply ensure the back-end server responds to SSLv3 client hello messages. It will not check any other health metrics, like status code or body contents.
https://review.openstack.org/#/c/475944/
实际上客户并未使用客户端认证, 所以不是上面的原因, 应该是SNI所致. 因为后端有SNI认证, haproxy端需传入hostname, 但haproxy端无法传入hostname, 所以出错.但octavia-worker应该可以传SNI到后端.
ubuntu@zhhuabj-bastion:~/ca3$ curl --cacert ca.crt https://10.5.150.5
curl: (51) SSL: certificate subject name (www.server1.com) does not match target host name '10.5.150.5'
ubuntu@zhhuabj-bastion:~/ca3$ curl --resolve www.server1.com:443:10.5.150.5 -k https://www.server1.com
test1
什么是SNI, 就是ssl server端可能会根据每个节点的hostname生成不同的cert, 并启用SNI. 这样ssl client访问ssl server端时也应该将hostname也传过去. (注: SNIProxy是一个适用于 HTTPS 和 HTTP 的类似于透明代理的反向代理工具。它可以在 TCP 层直接将流量在不解包的情况下转发出来，实现不需要在代理服务器配置证书就能反向代理 HTTPS 网站的功能)
'curl -k’的方式测试无法很好的测试SNI, 最好是通过’openstack s_client’测试:
#Ideal Test to connect with SSLv3/No SNI
openssl s_client -ssl3 -connect 103.245.215.4:443
#openssl s_client -connect 192.168.254.214:9443 | openssl x509 -noout -text | grep DNS
#We can also send SNI using -servername:
openssl s_client -ssl3 -servername CERT_HOSTNAME -connect 103.245.215.4:443
这个文档 (https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#option%20ssl-hello-chk )指出ssl-hello-chk只检查SSLv3不检查HTTP, 事实上, HTTPS health check也不检查HTTP只是多了个SSL negotiation. check-ssl check似乎能做更多.
LBaas v2模板目前只支持"httpchk"与"ssl-hello-chk", 这只有SSL check, 没有HTTP check. 所以问题很可能是出在SSLv3 hello (without SNI)有问题.做个SNI相关的实验验证一下:
首先, charm应该将ca传给octavia, ocavia应该根据ca再去创建SNI证书, 并且传SNI证书到backend, octavia-worker的相关处理代码如下:
LOG.debug("request url %s", path)_request = getattr(self.session, method.lower())_url = self._base_url(amp.lb_network_ip) + pathLOG.debug("request url %s", _url)reqargs = {'verify': CONF.haproxy_amphora.server_ca,'url': _url,'timeout': (req_conn_timeout, req_read_timeout), }reqargs.update(kwargs)headers = reqargs.setdefault('headers', {})headers['User-Agent'] = OCTAVIA_API_CLIENTself.ssl_adapter.uuid = amp.idexception = None# Keep retryingdef get_create_amphora_flow(self):"""Creates a flow to create an amphora.:returns: The flow for creating the amphora"""create_amphora_flow = linear_flow.Flow(constants.CREATE_AMPHORA_FLOW)create_amphora_flow.add(database_tasks.CreateAmphoraInDB(provides=constants.AMPHORA_ID))create_amphora_flow.add(lifecycle_tasks.AmphoraIDToErrorOnRevertTask(requires=constants.AMPHORA_ID))if self.REST_AMPHORA_DRIVER:create_amphora_flow.add(cert_task.GenerateServerPEMTask(create_amphora_flow.add(database_tasks.UpdateAmphoraDBCertExpiration(requires=(constants.AMPHORA_ID, constants.SERVER_PEM)))create_amphora_flow.add(compute_tasks.CertComputeCreate(requires=(constants.AMPHORA_ID, constants.SERVER_PEM,constants.BUILD_TYPE_PRIORITY, constants.FLAVOR),provides=constants.COMPUTE_ID))
1, 两个证书, 略. lb_tls_secret_1的hostname是www.server1.com, lb_tls_secret_2的hostname是www.server2.com
secret1_id=$(openstack secret list |grep lb_tls_secret_1 |awk '{print $2}')
secret2_id=$(openstack secret list |grep lb_tls_secret_2 |awk '{print $2}')
2, 创建listener时使用( --sni-container-refs $secret1_id $secret2_id )加入了两个域名的SNI
IP=192.168.21.7
secret1_id=$(openstack secret list |grep lb_tls_secret_1 |awk '{print $2}')
secret2_id=$(openstack secret list |grep lb_tls_secret_2 |awk '{print $2}')
subnetid=$(openstack subnet show private_subnet -f value -c id); echo $subnetid
lb_id=$(openstack loadbalancer show lb3 -f value -c id)
#lb_id=$(openstack loadbalancer create --name test_tls_termination --vip-subnet-id $subnetid -f value -c id); echo $lb_id
listener_id=$(openstack loadbalancer listener create $lb_id --name https_listener --protocol-port 443 --protocol TERMINATED_HTTPS --default-tls-container=$secret1_id --sni-container-refs $secret1_id $secret2_id -f value -c id); echo $listener_id
pool_id=$(openstack loadbalancer pool create --protocol HTTP --listener $listener_id --lb-algorithm ROUND_ROBIN -f value -c id); echo $pool_id
openstack loadbalancer member create --address ${IP} --subnet-id $subnetid --protocol-port 80 $pool_idpublic_network=$(openstack network show ext_net -f value -c id)
fip=$(openstack floating ip create $public_network -f value -c floating_ip_address)
vip=$(openstack loadbalancer show $lb_id -c vip_address -f value)
vip_port=$(openstack port list --fixed-ip ip-address=$vip -c ID -f value)
openstack floating ip set $fip --fixed-ip-address $vip --port $vip_port
3, 测试, client传入www.server1.com或www.server2.com两个域名时, server端能正常响应, 但传入一个域名www.server3.com时就报了这个错:‘does not match target host name ‘www.server3.com’’
ubuntu@zhhuabj-bastion:~/ca3$ curl --resolve www.server1.com:443:10.5.150.5 --cacert ca.crt https://www.server1.com
Hello World!
ubuntu@zhhuabj-bastion:~/ca3$ curl --resolve www.server2.com:443:10.5.150.5 --cacert ca.crt https://www.server2.com
Hello World!
ubuntu@zhhuabj-bastion:~/ca3$ curl --resolve www.server3.com:443:10.5.150.5 --cacert ca.crt https://www.server3.com
curl: (51) SSL: certificate subject name (www.server1.com) does not match target host name 'www.server3.com'
为什么会这样呢?
LBaaS v2中的ssl check将在haproxy中添加下列配置, 实际上有ssl-hello-chk时httpchk将被覆盖(haproxy忽略的). haproxy 1.7开始添加了更高级的check-ssl(xenial使用haproxy 1.6, 不支持), 估计就是早期的lbaas为ssl check添加ssl-hello-chk的原因
mode tcp
option httpchk GET /
http-check expect rstatus 303
option ssl-hello-chk
haproxy(http://cbonte.github.io/haproxy-dconv/1.6/configuration.html#4-option%20ssl-hello-chk)将为ssl-hello-chk伪造SSLv3包.
When some SSL-based protocols are relayed in TCP mode through HAProxy, it is
possible to test that the server correctly talks SSL instead of just testing
that it accepts the TCP connection. When "option ssl-hello-chk" is set, pure
SSLv3 client hello messages are sent once the connection is established to
the server, and the response is analyzed to find an SSL server hello message.
The server is considered valid only when the response contains this server
hello message.
All servers tested till there correctly reply to SSLv3 client hello messages,
and most servers tested do not even log the requests containing only hello
messages, which is appreciable.
Note that this check works even when SSL support was not built into haproxy
because it forges the SSL message. When SSL support is available, it is best
to use native SSL health checks instead of this one.
这是haproxy相关处理的源代码, 它没使用SSL libray, 先发硬编码的SSLv3 hello消息, 然后从response里找0x15 (SSL3_RT_ALERT) or 0x16 (SSL3_RT_HANDSHAKE), 若没找着就返回HCHK_STATUS_L6RSP(Layer6 invalid response) - https://github.com/haproxy/haproxy/blob/master/src/checks.c#L915
case PR_O2_SSL3_CHK:if (!done && b_data(&check->bi) < 5)goto wait_more_data;/* Check for SSLv3 alert or handshake */if ((b_data(&check->bi) >= 5) && (*b_head(&check->bi) == 0x15 || *b_head(&check->bi) == 0x16))set_server_check_status(check, HCHK_STATUS_L6OK, NULL);elseset_server_check_status(check, HCHK_STATUS_L6RSP, NULL);break;
错误’Layer6 invalid response’正是从客户日志中看到的:
Oct 25 04:50:34 neut002 haproxy[54990]: Server aaa0a533-073b-4b0f-8b81-777b6a8f3900/f2dc685f-58f7-4201-8060-3409d2d73a0d is DOWN, reason: Layer6 invalid response, check duration: 4ms. 0 active and 0 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
所以backend ssl server端应该返回0x15, 客户究竟在haproxy之前运行什么ssl backend端, 我们不清楚. 假设它们运行的是apache2. 我们搭建一个测试环境, apache2采用默认的tls1.2, 而haproxy里还使用老的sslv3 hello时, apache2 ssl backend将返回下列的ssl协商错误:
ubuntu@zhhuabj-bastion:~/ca3$ openssl s_client -ssl3 -connect www.server1.com:443
140306875094680:error:140A90C4:SSL routines:SSL_CTX_new:null ssl method passed:ssl_lib.c:1878:
ubuntu@zhhuabj-bastion:~/ca3$ openssl s_client -ssl3 -servername www.server1.com -connect www.server1.com:443

ubuntu@zhhuabj-bastion:~/ca3$ openssl s_client -ssl3 -servername www.server2.com -connect www.server1.com:443
140564176807576:error:140A90C4:SSL routines:SSL_CTX_new:null ssl method passed:ssl_lib.c:1878:
为什么ssl backend端不返回0x15或0x16呢, 理论上可能有以下几个原因
a, SSLv3现在已经被废弃了, 主流http server已经禁用了SSLv3支持, apach2收到haproxy过来的SSLv3 hello包时, apache2的SSL实现可能会响应别的消息而不是0x15/0x15
b, 因为haproxy过来的SSLv3 hello请求里没有SNI, 这样若启用了SNI的backend端(如apache2)就会ssl协商失败了, 这样也就未返回0x15/0x16
c, 其他原因
具体原因还需继续在backend抓包(tcpdump -eni ens3 -w ssl-test.pcap -s 0 port 443 or port 8443)确认.
更新, 原因已找到:
octavia/0会创建amphorae service vm, octavia/0上的/usr/lib/python3/dist-packages/octavia/amphorae/drivers/haproxy/rest_api_driver.py采用python requests模块去连接service vm上的9443端口. 这块代码类似下面这句所以不work:
curl --cacert /etc/octavia/certs/issuing_ca.pem 192.168.254.31:9443
改试下面的都work , 其中26835e25-7c4f-4776-940f-209eb9a9e826是SNI (loadbalance-id).
curl -k 192.168.254.31:9443
openssl s_client -connect 192.168.254.31:9443 -key /etc/octavia/certs/issuing_ca_key.pem

#tlsv13 alert certificate required, it shows ssh client verfication is required
curl -6 -k https://[fc00:ea96:ae23:2d4f:f816:3eff:fe76:d87a]:9443/
#no alternative certificate subject name matches target host name, it shows it's about sni
curl -6 --cacert /etc/octavia/certs/issuing_ca.pem https://[fc00:ea96:ae23:2d4f:f816:3eff:fe76:d87a]:9443/
curl -6 --cacert /etc/octavia/certs/issuing_ca.pem --resolve backend1.domain:9443:[fc00:ea96:ae23:2d4f:f816:3eff:fe76:d87a] https://backend1.domain:9443 -v
在octavia/0上测试:
openssl s_client -connect 192.168.254.31:9443 -key /etc/octavia/certs/issuing_ca_key.pem
最后的原因是, 创建证书时未指明CN=$DOMAIN1:
SUBJECT="/C=CN/ST=BJ/L=BJ/O=STS/OU=Joshua/CN=$DOMAIN1"
openssl req -new -nodes -subj $SUBJECT -key $DOMAIN1.key -out $DOMAIN1.csr我们知道, python requests module中的assert_hostname用来往backend传递SNI, 见 - https://medium.com/@yzlin/python-requests-ssl-ip-binding-6df25a9a8f6a
而下列代码(https://github.com/openstack/octavia/blob/master/octavia/amphorae/drivers/haproxy/rest_api_driver.py#L542), 将传self.uuid(self.ssl_adapter.uuid = amp.id)到conn.asser_hostname.
class CustomHostNameCheckingAdapter(requests.adapters.HTTPAdapter):def cert_verify(self, conn, url, verify, cert):conn.assert_hostname = self.uuidreturn super(CustomHostNameCheckingAdapter,self).cert_verify(conn, url, verify, cert)

openstack security group rule create $secgroup --protocol udp --dst-port 546 --ethertype IPv6
最容易出现的问题是health-manager-octavia-0-listen-port port为DOWN, 从而o-hm0网络不通而无法从dhcp server处获得IP, 网段不通多半是br-int上的flow rules的问题, 我多次遇到这种情况, 但后来重建环境不知为什么又好了.

如果o-hm0总是无法获得IP, 我们也可以手工配置一个IPv4管理网段试试.

openssl req -new -x509 -keyout lb.pem -out lb.pem -days 365 -nodes -subj "/C=CN/ST=BJ/O=STS/CN=www.quqi.com"
$ curl --resolve www.quqi.com:443:192.168.99.135 --cacert ./lb.pem https://www.quqi.com

经进一步调试, 原来是因为 这一句"curl --resolve www.quqi.com:443:10.5.150.4 --cacert ~/ca/ca.crt https://www.quqi.com"应该是"curl --resolve www.quqi.com:443:10.5.150.4 --cacert ~/ca/lb.pem https://www.quqi.com"
或者使用apache2安装ssl

测试虚机中安装HTTP测试服务
下面的这种HTTP测试服务实际上有问题, 会导致haproxy对backend作check时报下列错误.
ae847e94-5aeb-4da6-9b66-07e1a385465b is UP, reason: Layer7 check passed, code: 200, info: "HTTP status check returned code <3C>200<3E>", check duration: 7ms. 1 active and 0 backup servers online. 0 sessions requeued, 0 total in queue.
1, deploy http server in backend
MYIP=$(ifconfig ens2|grep 'inet addr'|awk -F: '{print $2}'| awk '{print $1}')
while true; do echo -e "HTTP/1.0 200 OK\r\n\r\nWelcome to $MYIP" | sudo nc -l -p 80 ; done
2, test it
sudo ip netns exec qrouter-2ea1fc45-69e5-4c77-b6c9-d4fabc57145b curl http://192.168.21.7:80
3, add it into haproxy
openstack loadbalancer member create --subnet-id private_subnet --address 192.168.21.7 --protocol-port 80 pool1
并且还会导致在作haproxy vip作curl测试时返回Bad Gateway的错误.
所以最后在backend上运行"sudo python -m SimpleHTTPServer 80"之后解决.

目前剩下的问题是service vm无法访问backend 192.168.21.7, 原理应该是:
octavia通过_plug_amphora_vip方法添加一个vip port (octavia-lb-vrrp-7e56de03-298e-43dd-a78f-33aa8d4af735), 它应该往amphora虚机上再添加一个port, 然后为此vip添加allowed_address_pairs. 但是在amphora虚机上我们没有发现这块新添的vip NIC, 重新运行下列’nova interface-attach’也不好使
nova list --all
nova interface-attach --port-id $(neutron port-show octavia-lb-vrrp-f63f0c5b-a541-442a-929c-b8ed7f7b3604 -f value -c id) 044f42c9-d205-4a11-aa8f-6b9aea896861
使用下列方法也不好使:
lb_id=$(openstack loadbalancer show lb3 -f value -c id)
old_vip=$(openstack loadbalancer show lb3 -f value -c vip_address)
private_subnet_id=$(neutron subnet-show private_subnet -f value -c id)
# delete old vip port (named 'octavia-lb-$lb_id')
neutron port-delete octavia-lb-$lb_id
# create new vip port with the same name and vip and binding:host_id is amphora service vm's host
# nova show $(nova list --all |grep amphora |awk '{print $2}') |grep OS-EXT-SRV-ATTR:host
neutron port-create --name octavia-lb-$lb_id --device-owner Octavia --binding:host_id=juju-50fb86-bionic-rocky-barbican-octavia-8 --fixed-ip subnet_id=${private_subnet_id},ip_address=${old_vip} private
mac=$(neutron port-show octavia-lb-$lb_id -f value -c mac_address)
nova interface-attach --port-id $(neutron port-show octavia-lb-$lb_id -f value -c id) $(nova list --all |grep amphora |awk '{print $2}')接着发现admin-state-up为False, 但enable(neutron port-update --admin-state-up True 6dc5b0bd-d0b7-4b29-9fce-b8f7b23c7914)后status仍然为DOWN. 继续检查设置如下;

继续查找原因, 既然从service vm能ping backend说明网络都没问题, 现在只是无法从gateway ping service vm那说明应该还是防火墙的问题. 采用’neutron port-show '查看该vip port关联的是一个新security group, 添加之后问题解决:
openstack security group rule create --protocol tcp --dst-port 22 lb-7f2985f0-c0d5-47ab-b805-7f5dafe20d3e
openstack security group rule create --protocol icmp lb-7f2985f0-c0d5-47ab-b805-7f5dafe20d3e
接着就是报这个错, 后来确认是上面在backend模拟HTTP服务的方法有问题, 后改成"sudo python -m SimpleHTTPServer 80"后问题解决 .

附录 - 上层的k8s如何使用下层的openstack中的LBaaS资源
如果在一个OpenStack云上面再创建K8S的话, 在k8s中使用下列命令创建LoadBalancer服务会永远Pending状态.
kubectl run test-nginx --image=nginx --replicas=2 --port=80 --expose --service-overrides='{ "spec": { "type": "LoadBalancer" } }'
kubectl get svc test-nginx
那是因为k8s需要调用底层OpenStack LBaaS服务创建VIP资源, 然后将所有后端服务的NodeIP:NodePort作为backend. 那么该如何让k8s具有访问openstack lbaas资源的能力呢? 如下:
# https://blog.ubuntu.com/2019/01/28/taking-octavia-for-a-ride-with-kubernetes-on-openstack
# openstack上部署k8s, 'juju trust openstack-integrator'将让openstack-integrator具有访问bootstrap时所用的openstack credential的权限,
# 之后, 因为cdk实现了interface-openstack-integration接口, 所以cdk k8s可以使用这些openstack credential来直接使用openstack里的LBaaS等资源
juju deploy cs:~containers/openstack-integrator

juju add-relation openstack-integrator kubernetes-worker
juju config openstack-integrator subnet-id=<UUID of subnet>
juju config openstack-integrator floating-network-id=<UUID of ext_net># 'juju trust' grants openstack-integrator access to the credential used in the bootstrap command, this charm acts as a proxy for the
juju trust openstack-integrator测试yaml, 有时要提供loadbalancer.openstack.org/floating-network-id, 见: https://github.com/kubernetes/cloud-provider-openstack/tree/master/examples/loadbalancers

spec:selector:app: nginxtype: LoadBalancerports:- name: httpport: 80targetPort: 80
同时也应该确保service tenant下的security group的quata别超了.quata超了的现象是例如对于FIP, 有时可以有时不可以.
后面继续搭建k8s可参见 - https://ubuntu.com/blog/taking-octavia-for-a-ride-with-kubernetes-on-openstack

遇到又一例, service vm不work, 创建lb后, service vm是ACTIVE状态其管理网段IP也work, 但LB的状态是PENDING_STATE, 但LB有VIP也可以ssh, 但过一会之后, service vm变成ERROR状态且被删除. 查出来的原因是:
During verification of the agent update, It was also found that firewall changes introduced caused DNS to become unreachable for the octavia load balancer instances. These rules have been updated to allow access, which allowed DNS to work inside the amphora VMs, which in turn, in combination with disabling a host, and the update of the agent,returned the load balancers to a working 'state."
20200220更新
用下列方法更新添加nbthread元素之后，LB创建成功后一会儿死掉，
juju config octavia haproxy-template | base64 -d > /tmp/haproxy-custom.j2
vim /tmp/haproxy-custom.j2 # edit the nbthread option
nbproc 1
nbthread 2
cpu-map auto:1/1-2 0-1
maxconns=64000
juju config octavia haproxy-template="$(base64 /tmp/haproxy-custom.j2)"
这种问题一般能从octavia-worker.log中找到答案：
2020-02-19 04:53:11.465 14180 ERROR octavia.controller.worker.controller_worker jinja2.exceptions.UndefinedError: 'dict object' has no attribute 'listener'
原因是这个patch(https://review.opendev.org/#/c/673518/)引入了combined_listeners, combined_listeners是为了解决下列问题：
Since 1.8.x version, haproxy consumes at least 160MB at init time using the default configuration provided by octavia. When a LB is updated, haproxy configuration is updated and a signal is sent to haproxy to reload the configuration.
When haproxy reloads its configuration, it creates a new worker, does some allocations (up to 160MB), then destroys the previous worker. So during a short time, memory consumption is increased, and if 2 processes reload a the same time, it may fail with a "Cannot fork" error.
所以custom template (https://paste.ubuntu.com/p/PGvD7fzjd2/ )中的之前的split_listeners的中loadbalancer.listener.pools应该改成现在combined_listeners中的loadbalancer.listeners.pools
20200427更新 -
另一个问题, 如下, socket.getfqdn在处理/etc/hosts里的fqdn(见: https://bugs.python.org/issue5004), 所以还是要使用socket.getaddrinfo代替socket.getfqdn来处理fqdn (neutron agent现在改成使用fqdn注册), 但观察到socket.getaddrinfo时时而能获取到fqdn时而不能获取, 从而导致octavia里的出现binding error从而导致o-hm0无法获取IP.
ubuntu@juju-5b1810-octavia-6:~$ python3 -c 'import socket; print(socket.getaddrinfo("juju-5b1810-octavia-6", None, 0, socket.SOCK_DGRAM, 0,

juju-5b1810-octavia-6
尤其是vm里的/etc/resovle.conf里用到了如maas dns与neutron ml2-dns等多个search项时, ml2-dns的search项排到第一位时会导致octavia上的l2-agent无法正常处理fqdn从而导致 o-hm0无IP, 见: https://bugs.launchpad.net/charm-octavia/+bug/1845303/comments/15
while true; do for X in {0..2}; do juju ssh octavia/$X "cat /etc/resolv.conf | grep -v "^#"; sudo python -c 'import socket; name=socket.gethostname(); addrs = socket.getaddrinfo(name, None, 0, socket.SOCK_DGRAM, 0, socket.AI_CANONNAME); print(addrs)'" 2>/dev/null; done; done
解决方法是在systemd-network中使用UseDomains=route
UseDomains接受布尔参数或特殊值“ route”。设置为true时，将从DHCP服务器(neutron dns)收到的域名用作DNS, 通过该链接搜索域。如果设置为“ route”，则从DHCP接收的域名 , 服务器将仅用于路由DNS查询.

+-------------------------------------+----------------------------------------------------------------------------+20210601 - immutable and cannot be updated
As explained here [2], All objects in Octavia should and will end in a consistent state: ACTIVE or ERROR.
PENDING_* means the object is actively being worked on by a controller that has locked the object to make
sure others do not make changes to this object while the controller is working on the object.So in other words, we can see this immutable error, which means that at the momnet of the error, lb's
state or listener's state must be PENDING_* according to [3] and [4].and this state is transient. How can Octavia object be in PENDING_* state? The code [5] shows healthmonitor will change the pool status to PENDING_* and then back to ACTIVE once healthmonitor creation finishes. So HM(healthmonitor) creation is fine and they should wait until LB/pool is back to ACTIVE before adding
members, if not they will hit immutable since state will be like PENDING_UPDATE. [2] https://bugs.launchpad.net/octavia/+bug/1498130/comments/14

20210603 - 修复LB状态
有时LB处于error状态，其amphora vm有的role是None，有的amphora vm从nova show中看不到虚机，可通过下列方法修复
删除role为none的amphora行之后，LB的状态才会进入PENDING_UPDATE状态

这次的问题是o-hm0是DOWN状态的:
- 有fe00的ipv6 mgmt地址，只是是DOWN状态。所以neutron-keepalived-state-change应该没问题，它能正常触发active/standby, keepalived应该也没问题因为有IP嘛
- 应该是l3-agent的问题造成port没有UP, l3-agent的问题可能是SG太多造成的CPU load
- disable HA for mgmt newtork 可能解决问题
- 如果只是ipv6方面的问题，也可以switch mght newtork from ipv6 to ipv4

OVN supported DHCP options - https://docs.openstack.org/neutron/latest/ovn/dhcp_opts.html
neutron port-update <PORT_ID> --extra-dhcp-opt opt_name=‘server-ip-address’,opt_value=‘10.0.0.1’
neutron port-update <PORT_ID> --extra-dhcp-opt ip_version=4, opt_name=dhcp_disabled, opt_value=false
#Using the native DHCP feature provided by OVN - https://docs.openstack.org/networking-ovn/ocata/design/native_dhcp.html
OVN implements a native DHCPv6 support similar to DHCPv4. When a v6 subnet is created, the OVN ML2 driver will insert a new entry into DHCP_Options table only when the subnet ‘ipv6_address_mode’ is not ‘slaac’, and enable_dhcp is True.
347 def is_dhcp_options_ignored(subnet):
348 # Don't insert DHCP_Options entry for v6 subnet with 'SLAAC' as
349 # 'ipv6_address_mode', since DHCPv6 shouldn't work for this mode.
350 return (subnet['ip_version'] == const.IP_VERSION_6 and
351 subnet.get('ipv6_address_mode') == const.IPV6_SLAAC)
所以slaac类型的IPv6是没有dhcp的（那就不通过dhcpv6 server来提供前缀和dns信息），那就只有通过router来提供前缀, 那问题就出在router端．
对于router port (lrp-xxx)如果定义了 HA Chassis Group 就会bind到 highest priority chassis, 否则通过requested-chassis设置(create_port|update_port -> _get_port_options)
1, 可以看到lrp-xxx port是没有requested-chassis属性的

通过’nova reboot’启动amphora之后’nova list --all’看到状态正常了，但 'openstack loadbalancer amphora list’仍看到ERROR．最后通过下列脚本恢复状态.
DB_PASS=$(juju run -u mysql/leader leader-get mysql.passwd)
DB_IP=$(juju ssh mysql/leader -- ip addr show ens3 |grep global |awk '{print $2}' |awk -F/ '{print $1}')
LB_IDS=$(openstack loadbalancer amphora list --status ERROR -c loadbalancer_id -f value | sort | uniq)
AMPHORA_IDS=$(openstack loadbalancer amphora list --status ERROR --loadbalancer ${LB_ID} -c id -f value)
for LB_ID in ${LB_IDS}; do# update LB status to ACTIVEjuju ssh mysql/leader -- "sudo mysql --database=octavia --user=root --password=${DB_PASS} \--execute=\"update load_balancer set provisioning_status='ACTIVE' where id='${LB_ID}';\""# get amphora IDAMPHORA_IDS=$(openstack loadbalancer amphora list --status ERROR --loadbalancer ${LB_ID} -c id -f value)for AMPHORA_ID in ${AMPHORA_IDS}; do# failover broken amphora VMsopenstack loadbalancer amphora failover ${AMPHORA_ID}sleep 60done
done
在这个过程中，会看到下列中间状态
