[root@k8s-master-01 ingress-nginx]# kubectl get pod -o wide

配置host后访问报504

[root@k8s-worker-02 harbor]# netstat -ntpl|grep 443
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      24716/nginx: master 
tcp6       0      0 :::443                  :::*                    LISTEN      24716/nginx: master 
[root@k8s-worker-02 harbor]# netstat -ntpl|grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      24716/nginx: master

tcp6       0      0 :::80                   :::*                    LISTEN      24716/nginx: master 
tcp6       0      0 :::18080                :::*                    LISTEN      24716/nginx: master 

我用最新版的mandatory.yaml访问报503，日志显示已经Type:“ContainerStarted”

求老师教下排查思路

ingress与pod是不是得在一个worker节点上，我部署在同一节点就正常了

  恩 那跟ingress没关系了，基本是cni的问题，差一下calico的启动日志，注意开头的部分，是否网桥选错了
